Runs and maintains your desired number of tasks from a specified task definition. If the number of tasks running in a service drops below the desiredCount , Amazon ECS runs another copy of the task in the specified cluster. To update an existing service, see the UpdateService action.
Note
Starting April 15, 2023, Amazon Web Services will not onboard new customers to Amazon Elastic Inference (EI), and will help current customers migrate their workloads to options that offer better price and performance. After April 15, 2023, new customers will not be able to launch instances with Amazon EI accelerators in Amazon SageMaker, Amazon ECS, or Amazon EC2. However, customers who have used Amazon EI at least once during the past 30-day period are considered current customers and will be able to continue using the service.
In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind one or more load balancers. The load balancers distribute traffic across the tasks that are associated with the service. For more information, see Service load balancing in the Amazon Elastic Container Service Developer Guide .
You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when creating or updating a service. volumeConfigurations is only supported for REPLICA service and not DAEMON service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide .
Tasks for services that don't use a load balancer are considered healthy if they're in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they're in the RUNNING state and are reported as healthy by the load balancer.
There are two service scheduler strategies available:
REPLICA - The replica scheduling strategy places and maintains your desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. For more information, see Service scheduler concepts in the Amazon Elastic Container Service Developer Guide .
DAEMON - The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It also stops tasks that don't meet the placement constraints. When using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies. For more information, see Service scheduler concepts in the Amazon Elastic Container Service Developer Guide .
You can optionally specify a deployment configuration for your service. The deployment is initiated by changing properties. For example, the deployment might be initiated by the task definition or by your desired count of a service. This is done with an UpdateService operation. The default value for a replica service for minimumHealthyPercent is 100%. The default value for a daemon service for minimumHealthyPercent is 0%.
If a service uses the ECS deployment controller, the minimum healthy percent represents a lower limit on the number of tasks in a service that must remain in the RUNNING state during a deployment. Specifically, it represents it as a percentage of your desired number of tasks (rounded up to the nearest integer). This happens when any of your container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. Using this parameter, you can deploy without using additional cluster capacity. For example, if you set your service to have desired number of four tasks and a minimum healthy percent of 50%, the scheduler might stop two existing tasks to free up cluster capacity before starting two new tasks. If they're in the RUNNING state, tasks for services that don't use a load balancer are considered healthy . If they're in the RUNNING state and reported as healthy by the load balancer, tasks for services that do use a load balancer are considered healthy . The default value for minimum healthy percent is 100%.
If a service uses the ECS deployment controller, the maximum percent parameter represents an upper limit on the number of tasks in a service that are allowed in the RUNNING or PENDING state during a deployment. Specifically, it represents it as a percentage of the desired number of tasks (rounded down to the nearest integer). This happens when any of your container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. Using this parameter, you can define the deployment batch size. For example, if your service has a desired number of four tasks and a maximum percent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximum percent is 200%.
If a service uses either the CODE_DEPLOY or EXTERNAL deployment controller types and tasks that use the EC2 launch type, the minimum healthy percent and maximum percent values are used only to define the lower and upper limit on the number of the tasks in the service that remain in the RUNNING state. This is while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the minimum healthy percent and maximum percent values aren't used. This is the case even if they're currently visible when describing your service.
When creating a service that uses the EXTERNAL deployment controller, you can specify only parameters that aren't controlled at the task set level. The only required parameter is the service name. You control your services using the CreateTaskSet operation. For more information, see Amazon ECS deployment types in the Amazon Elastic Container Service Developer Guide .
When the service scheduler launches new tasks, it determines task placement. For information about task placement and task placement strategies, see Amazon ECS task placement in the Amazon Elastic Container Service Developer Guide .

string
The short name or full Amazon Resource Name (ARN) of the cluster that you run your service on. If you do not specify a cluster, the default cluster is assumed.
string
[REQUIRED]
The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a Region or across multiple Regions.
string
The family and revision ( family:revision ) or full ARN of the task definition to run in your service. If a revision isn't specified, the latest ACTIVE revision is used.
A task definition must be specified if the service uses either the ECS or CODE_DEPLOY deployment controllers.
For more information about deployment types, see Amazon ECS deployment types.
list
A load balancer object representing the load balancers to use with your service. For more information, see Service load balancing in the Amazon Elastic Container Service Developer Guide .
If the service uses the rolling update ( ECS ) deployment controller and using either an Application Load Balancer or Network Load Balancer, you must specify one or more target group ARNs to attach to the service. The service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide .
If the service uses the CODE_DEPLOY deployment controller, the service is required to use either an Application Load Balancer or Network Load Balancer. When creating an CodeDeploy deployment group, you specify two target groups (referred to as a targetGroupPair ). During a deployment, CodeDeploy determines which task set in your service has the status PRIMARY , and it associates one target group with it. Then, it also associates the other target group with the replacement task set. The load balancer can also have up to two listeners: a required listener for production traffic and an optional listener that you can use to perform validation tests with Lambda functions before routing production traffic to it.
If you use the CODE_DEPLOY deployment controller, these values can be changed when updating the service.
For Application Load Balancers and Network Load Balancers, this object must contain the load balancer target group ARN, the container name, and the container port to access from the load balancer. The container name must be as it appears in a container definition. The load balancer name parameter must be omitted. When a task from this service is placed on a container instance, the container instance and port combination is registered as a target in the target group that's specified here.
For Classic Load Balancers, this object must contain the load balancer name, the container name , and the container port to access from the load balancer. The container name must be as it appears in a container definition. The target group ARN parameter must be omitted. When a task from this service is placed on a container instance, the container instance is registered with the load balancer that's specified here.
Services with tasks that use the awsvpc network mode (for example, those with the Fargate launch type) only support Application Load Balancers and Network Load Balancers. Classic Load Balancers aren't supported. Also, when you create any target groups for these services, you must choose ip as the target type, not instance . This is because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
(dict) --
The load balancer configuration to use with a service or task set.
When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.
We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.
A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.
list
The details of the service discovery registry to associate with this service. For more information, see Service discovery.
Note
Each service may be associated with one service registry. Multiple service registries for each service isn't supported.
(dict) --
The details for the service registry.
Each service may be associated with one service registry. Multiple service registries for each service are not supported.
When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.
port (integer) --
The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
containerPort (integer) --
The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
integer
The number of instantiations of the specified task definition to place and keep running in your service.
This is required if schedulingStrategy is REPLICA or isn't specified. If schedulingStrategy is DAEMON then this isn't required.
string
An identifier that you provide to ensure the idempotency of the request. It must be unique and is case sensitive. Up to 36 ASCII characters in the range of 33-126 (inclusive) are allowed.
string
The infrastructure that you run your service on. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .
The FARGATE launch type runs your tasks on Fargate On-Demand infrastructure.
Note
Fargate Spot infrastructure is available for use but a capacity provider strategy must be used. For more information, see Fargate capacity providers in the Amazon ECS User Guide for Fargate .
The EC2 launch type runs your tasks on Amazon EC2 instances registered to your cluster.
The EXTERNAL launch type runs your tasks on your on-premises server or virtual machine (VM) capacity registered to your cluster.
A service can use either a launch type or a capacity provider strategy. If a launchType is specified, the capacityProviderStrategy parameter must be omitted.
list
The capacity provider strategy to use for the service.
If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.
A capacity provider strategy may contain a maximum of 6 capacity providers.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
A capacity provider strategy may contain a maximum of 6 capacity providers.
capacityProvider (string) -- [REQUIRED]
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
string
The platform version that your tasks in the service are running on. A platform version is specified only for tasks using the Fargate launch type. If one isn't specified, the LATEST platform version is used. For more information, see Fargate platform versions in the Amazon Elastic Container Service Developer Guide .
string
The name or full Amazon Resource Name (ARN) of the IAM role that allows Amazon ECS to make calls to your load balancer on your behalf. This parameter is only permitted if you are using a load balancer with your service and your task definition doesn't use the awsvpc network mode. If you specify the role parameter, you must also specify a load balancer object with the loadBalancers parameter.
Warning
If your account has already created the Amazon ECS service-linked role, that role is used for your service unless you specify a role here. The service-linked role is required if your task definition uses the awsvpc network mode or if the service is configured to use service discovery, an external deployment controller, multiple target groups, or Elastic Inference accelerators in which case you don't specify a role here. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide .
If your specified role has a path other than / , then you must either specify the full role ARN (this is recommended) or prefix the role name with the path. For example, if a role with the name bar has a path of /foo/ then you would specify /foo/bar as the role name. For more information, see Friendly names and paths in the IAM User Guide .
dict
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker (dict) --
Note
The deployment circuit breaker can only be used for services using the rolling update ( ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable (boolean) -- [REQUIRED]
Determines whether to use the deployment circuit breaker logic for the service.
rollback (boolean) -- [REQUIRED]
Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
minimumHealthyPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.
For services that do not use a load balancer, the following should be noted:
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services are that do use a load balancer, the following should be noted:
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.
alarms (dict) --
Information about the CloudWatch alarms.
alarmNames (list) -- [REQUIRED]
One or more CloudWatch alarm names. Use a "," to separate the alarms.
(string) --
enable (boolean) -- [REQUIRED]
Determines whether to use the CloudWatch alarm option in the service deployment process.
rollback (boolean) -- [REQUIRED]
Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
list
An array of placement constraint objects to use for tasks in your service. You can specify a maximum of 10 constraints for each task. This limit includes constraints in the task definition and those specified at runtime.
(dict) --
An object representing a constraint on task placement. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide .
Note
If you're using the Fargate launch type, task placement constraints aren't supported.
type (string) --
The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
expression (string) --
A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is distinctInstance . For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .
list
The placement strategy objects to use for tasks in your service. You can specify a maximum of 5 strategy rules for each service.
(dict) --
The task placement strategy for a task or service. For more information, see Task placement strategies in the Amazon Elastic Container Service Developer Guide .
type (string) --
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.
field (string) --
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.
dict
The network configuration for the service. This parameter is required for task definitions that use the awsvpc network mode to receive their own elastic network interface, and it isn't supported for other network modes. For more information, see Task networking in the Amazon Elastic Container Service Developer Guide .
awsvpcConfiguration (dict) --
The VPC subnets and security groups that are associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
subnets (list) -- [REQUIRED]
The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per AwsVpcConfiguration .
Note
All specified subnets must be from the same VPC.
(string) --
securityGroups (list) --
The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
(string) --
assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
integer
The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started. This is only used when your service is configured to use a load balancer. If your service has a load balancer defined and you don't specify a health check grace period value, the default value of 0 is used.
If you do not use an Elastic Load Balancing, we recommend that you use the startPeriod in the task definition health check parameters. For more information, see Health check.
If your service's tasks take a while to start and respond to Elastic Load Balancing health checks, you can specify a health check grace period of up to 2,147,483,647 seconds (about 69 years). During that time, the Amazon ECS service scheduler ignores health check status. This grace period can prevent the service scheduler from marking tasks as unhealthy and stopping them before they have time to come up.
string
The scheduling strategy to use for the service. For more information, see Services.
There are two service scheduler strategies available:
REPLICA -The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. This scheduler strategy is required if the service uses the CODE_DEPLOY or EXTERNAL deployment controller types.
DAEMON -The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks and will stop tasks that don't meet the placement constraints. When you're using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies.
Note
Tasks using the Fargate launch type or the CODE_DEPLOY or EXTERNAL deployment controller types don't support the DAEMON scheduling strategy.
dict
The deployment controller to use for the service. If no deployment controller is specified, the default value of ECS is used.
type (string) -- [REQUIRED]
The deployment controller type to use.
There are three deployment controller types available:
ECS
The rolling update ( ECS ) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration.
CODE_DEPLOY
The blue/green ( CODE_DEPLOY ) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.
EXTERNAL
The external ( EXTERNAL ) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.
list
The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define. When a service is deleted, the tags are deleted as well.
The following basic restrictions apply to tags:
Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
boolean
Specifies whether to turn on Amazon ECS managed tags for the tasks within the service. For more information, see Tagging your Amazon ECS resources in the Amazon Elastic Container Service Developer Guide .
When you use Amazon ECS managed tags, you need to set the propagateTags request parameter.
string
Specifies whether to propagate the tags from the task definition to the task. If no value is specified, the tags aren't propagated. Tags can only be propagated to the task during task creation. To add tags to a task after task creation, use the TagResource API action.
The default is NONE .
boolean
Determines whether the execute command functionality is turned on for the service. If true , this enables execute command functionality on all containers in the service tasks.
dict
The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
enabled (boolean) -- [REQUIRED]
Specifies whether to use Service Connect with this service.
namespace (string) --
The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace for use with Service Connect. The namespace must be in the same Amazon Web Services Region as the Amazon ECS service and cluster. The type of namespace doesn't affect Service Connect. For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide .
services (list) --
The list of Service Connect service objects. These are names and aliases (also known as endpoints) that are used by other Amazon ECS services to connect to this service.
This field is not required for a "client" Amazon ECS service that's a member of a namespace only to connect to other services within the namespace. An example of this would be a frontend application that accepts incoming requests from either a load balancer that's attached to the service or by other means.
An object selects a port from the task definition, assigns a name for the Cloud Map service, and a list of aliases (endpoints) and ports for client applications to refer to this service.
(dict) --
The Service Connect service object configuration. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
portName (string) -- [REQUIRED]
The portName must match the name of one of the portMappings from all the containers in the task definition of this Amazon ECS service.
discoveryName (string) --
The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.
If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .
clientAliases (list) --
The list of client aliases for this Service Connect service. You use these to assign names that can be used by client applications. The maximum number of client aliases that you can have in this list is 1.
Each alias ("endpoint") is a fully-qualified name and port number that other Amazon ECS tasks ("clients") can use to connect to this service.
Each name and port mapping must be unique within the namespace.
For each ServiceConnectService , you must provide at least one clientAlias with one port .
(dict) --
Each alias ("endpoint") is a fully-qualified name and port number that other tasks ("clients") can use to connect to this service.
Each name and port mapping must be unique within the namespace.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
port (integer) -- [REQUIRED]
The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.
To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
dnsName (string) --
The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.
If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .
To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database , db , or the lowercase name of a database, such as mysql or redis . For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
ingressPortOverride (integer) --
The port number for the Service Connect proxy to listen on.
Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.
In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.
logConfiguration (dict) --
The log configuration for the container. This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run.
By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition. For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Understand the following when specifying a log configuration for your containers.
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent. For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens . For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide .
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.
logDriver (string) -- [REQUIRED]
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
(string) --
(string) --
secretOptions (list) --
The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.
To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.
For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
name (string) -- [REQUIRED]
The name of the secret.
valueFrom (string) -- [REQUIRED]
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide .
Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
list
The configuration for a volume specified in the task definition as a volume that is configured at launch time. Currently, the only supported volume type is an Amazon EBS volume.
(dict) --
The configuration for a volume specified in the task definition as a volume that is configured at launch time. Currently, the only supported volume type is an Amazon EBS volume.
name (string) -- [REQUIRED]
The name of the volume. This value must match the volume name from the Volume object in the task definition.
managedEBSVolume (dict) --
The configuration for the Amazon EBS volume that Amazon ECS creates and manages on your behalf. These settings are used to create each Amazon EBS volume, with one volume created for each task in the service. The Amazon EBS volumes are visible in your account in the Amazon EC2 console once they are created.
encrypted (boolean) --
Indicates whether the volume should be encrypted. If no value is specified, encryption is turned on by default. This parameter maps 1:1 with the Encrypted parameter of the CreateVolume API in the Amazon EC2 API Reference .
kmsKeyId (string) --
The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference .
Warning
Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.
volumeType (string) --
The volume type. This parameter maps 1:1 with the VolumeType parameter of the CreateVolume API in the Amazon EC2 API Reference . For more information, see Amazon EBS volume types in the Amazon EC2 User Guide .
The following are the supported volume types.
General Purpose SSD: gp2 | gp3
Provisioned IOPS SSD: io1 | io2
Throughput Optimized HDD: st1
Cold HDD: sc1
Magnetic: standard
Note
The magnetic volume type is not supported on Fargate.
sizeInGiB (integer) --
The size of the volume in GiB. You must specify either a volume size or a snapshot ID. If you specify a snapshot ID, the snapshot size is used for the volume size by default. You can optionally specify a volume size greater than or equal to the snapshot size. This parameter maps 1:1 with the Size parameter of the CreateVolume API in the Amazon EC2 API Reference .
The following are the supported volume size values for each volume type.
gp2 and gp3 : 1-16,384
io1 and io2 : 4-16,384
st1 and sc1 : 125-16,384
standard : 1-1,024
snapshotId (string) --
The snapshot that Amazon ECS uses to create the volume. You must specify either a snapshot ID or a volume size. This parameter maps 1:1 with the SnapshotId parameter of the CreateVolume API in the Amazon EC2 API Reference .
iops (integer) --
The number of I/O operations per second (IOPS). For gp3 , io1 , and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.
The following are the supported values for each volume type.
gp3 : 3,000 - 16,000 IOPS
io1 : 100 - 64,000 IOPS
io2 : 100 - 256,000 IOPS
This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS . This parameter is not supported for st1 , sc1 , or standard volume types.
This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference .
throughput (integer) --
The throughput to provision for a volume, in MiB/s, with a maximum of 1,000 MiB/s. This parameter maps 1:1 with the Throughput parameter of the CreateVolume API in the Amazon EC2 API Reference .
Warning
This parameter is only supported for the gp3 volume type.
tagSpecifications (list) --
The tags to apply to the volume. Amazon ECS applies service-managed tags by default. This parameter maps 1:1 with the TagSpecifications.N parameter of the CreateVolume API in the Amazon EC2 API Reference .
(dict) --
The tag specifications of an Amazon EBS volume.
resourceType (string) -- [REQUIRED]
The type of volume resource.
tags (list) --
The tags applied to this Amazon EBS volume. AmazonECSCreated and AmazonECSManaged are reserved tags that can't be used.
(dict) --
The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value. You define them.
The following basic restrictions apply to tags:
Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

Response Structure
(dict) --
service (dict) --
The full description of your service following the create call.
A service will return either a capacityProviderStrategy or launchType parameter, but not both, depending where one was specified when it was created.
If a service is using the ECS deployment controller, the deploymentController and taskSets parameters will not be returned.
if the service uses the CODE_DEPLOY deployment controller, the deploymentController , taskSets and deployments parameters will be returned, however the deployments parameter will be an empty list.
serviceArn (string) --
The ARN that identifies the service. For more information about the ARN format, see Amazon Resource Name (ARN) in the Amazon ECS Developer Guide .
serviceName (string) --
The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster. However, you can have similarly named services in multiple clusters within a Region or across multiple Regions.
clusterArn (string) --
The Amazon Resource Name (ARN) of the cluster that hosts the service.
loadBalancers (list) --
A list of Elastic Load Balancing load balancer objects. It contains the load balancer name, the container name, and the container port to access from the load balancer. The container name is as it appears in a container definition.
(dict) --
The load balancer configuration to use with a service or task set.
When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.
We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.
A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details for the service discovery registries to assign to this service. For more information, see Service Discovery.
(dict) --
The details for the service registry.
Each service may be associated with one service registry. Multiple service registries for each service are not supported.
When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.
port (integer) --
The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
containerPort (integer) --
The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
status (string) --
The status of the service. The valid values are ACTIVE , DRAINING , or INACTIVE .
desiredCount (integer) --
The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
runningCount (integer) --
The number of tasks in the cluster that are in the RUNNING state.
pendingCount (integer) --
The number of tasks in the cluster that are in the PENDING state.
launchType (string) --
The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.
capacityProviderStrategy (list) --
The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
A capacity provider strategy may contain a maximum of 6 capacity providers.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
platformVersion (string) --
The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn't specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
platformFamily (string) --
The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.
All tasks that run as part of this service must use the same platformFamily value as the service (for example, LINUX ).
taskDefinition (string) --
The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
deploymentConfiguration (dict) --
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker (dict) --
Note
The deployment circuit breaker can only be used for services using the rolling update ( ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable (boolean) --
Determines whether to use the deployment circuit breaker logic for the service.
rollback (boolean) --
Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
minimumHealthyPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.
For services that do not use a load balancer, the following should be noted:
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services are that do use a load balancer, the following should be noted:
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.

When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.
We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.
A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.

containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details for the service discovery registries to assign to this task set. For more information, see Service discovery.
(dict) --
The details for the service registry.
Each service may be associated with one service registry. Multiple service registries for each service are not supported.
When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
containerPort (integer) --
The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
port (integer) --
The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.
To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
dnsName (string) --
The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.
If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .
To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database , db , or the lowercase name of a database, such as mysql or redis . For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
ingressPortOverride (integer) --
The port number for the Service Connect proxy to listen on.
Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.
In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.
logConfiguration (dict) --
The log configuration for the container. This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run.
By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition. For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Understand the following when specifying a log configuration for your containers.
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent. For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens . For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide .
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.
logDriver (string) --
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
(string) --
(string) --
secretOptions (list) --
The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.
To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.
For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
name (string) --
The name of the secret.
valueFrom (string) --
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide .
Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
serviceConnectResources (list) --
The list of Service Connect resources that are associated with this deployment. Each list entry maps a discovery name to a Cloud Map service name.
(dict) --
The Service Connect resource. Each configuration maps a discovery name to a Cloud Map service name. The data is stored in Cloud Map as part of the Service Connect configuration for each discovery name of this Amazon ECS service.
A task can resolve the dnsName for each of the clientAliases of a service. However a task can't resolve the discovery names. If you want to connect to a service, refer to the ServiceConnectConfiguration of that service for the list of clientAliases that you can use.
discoveryName (string) --
The discovery name of this Service Connect resource.
The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.
If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .
discoveryArn (string) --

The Amazon EBS volumes are visible in your account in the Amazon EC2 console once they are created.
encrypted (boolean) --
Indicates whether the volume should be encrypted. If no value is specified, encryption is turned on by default. This parameter maps 1:1 with the Encrypted parameter of the CreateVolume API in the Amazon EC2 API Reference .
kmsKeyId (string) --
The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference .
Warning
Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.

iops (integer) --
The number of I/O operations per second (IOPS). For gp3 , io1 , and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.
The following are the supported values for each volume type.
gp3 : 3,000 - 16,000 IOPS
io1 : 100 - 64,000 IOPS
io2 : 100 - 256,000 IOPS
This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS . This parameter is not supported for st1 , sc1 , or standard volume types.
This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference .
throughput (integer) --
The throughput to provision for a volume, in MiB/s, with a maximum of 1,000 MiB/s. This parameter maps 1:1 with the Throughput parameter of the CreateVolume API in the Amazon EC2 API Reference .

For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

An object representing a constraint on task placement. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide .
Note
If you're using the Fargate launch type, task placement constraints aren't supported.
type (string) --
The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
expression (string) --
A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is distinctInstance . For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .
placementStrategy (list) --
The placement strategy that determines how tasks for the service are placed.
(dict) --
The task placement strategy for a task or service. For more information, see Task placement strategies in the Amazon Elastic Container Service Developer Guide .
type (string) --
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.
field (string) --
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.
networkConfiguration (dict) --
The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.

Note
All specified subnets must be from the same VPC.
(string) --
securityGroups (list) --
The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
(string) --
assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
healthCheckGracePeriodSeconds (integer) --

schedulingStrategy (string) --
The scheduling strategy to use for the service. For more information, see Services.
There are two service scheduler strategies available.
REPLICA -The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions.
DAEMON -The daemon scheduling strategy deploys exactly one task on each active container instance. This task meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It stop tasks that don't meet the placement constraints.
Note
Fargate tasks don't support the DAEMON scheduling strategy.
deploymentController (dict) --
The deployment controller type the service is using.
type (string) --
The deployment controller type to use.
There are three deployment controller types available:
ECS
The rolling update ( ECS ) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration.
CODE_DEPLOY
The blue/green ( CODE_DEPLOY ) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.
EXTERNAL
The external ( EXTERNAL ) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.
tags (list) --
The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value. You define bot the key and value.
The following basic restrictions apply to tags:
Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

Deletes a specified service within a cluster. You can delete a service if you have no running tasks in it and the desired task count is zero. If the service is actively maintaining tasks, you can't delete it, and you must update the service to a desired task count of zero. For more information, see UpdateService.
Note
When you delete a service, if there are still running tasks that require cleanup, the service status moves from ACTIVE to DRAINING , and the service is no longer visible in the console or in the ListServices API operation. After all tasks have transitioned to either STOPPING or STOPPED status, the service status moves from DRAINING to INACTIVE . Services in the DRAINING or INACTIVE status can still be viewed with the DescribeServices API operation. However, in the future, INACTIVE services may be cleaned up and purged from Amazon ECS record keeping, and DescribeServices calls on those services return a ServiceNotFoundException error.
Warning
If you attempt to create a new service with the same name as an existing service in either ACTIVE or DRAINING status, you receive an error.

service (dict) --
The full description of the deleted service.
serviceArn (string) --
The ARN that identifies the service. For more information about the ARN format, see Amazon Resource Name (ARN) in the Amazon ECS Developer Guide .
serviceName (string) --
The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster. However, you can have similarly named services in multiple clusters within a Region or across multiple Regions.
clusterArn (string) --
The Amazon Resource Name (ARN) of the cluster that hosts the service.
loadBalancers (list) --
A list of Elastic Load Balancing load balancer objects. It contains the load balancer name, the container name, and the container port to access from the load balancer. The container name is as it appears in a container definition.
(dict) --
The load balancer configuration to use with a service or task set.
When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.
We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.
A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details for the service discovery registries to assign to this service. For more information, see Service Discovery.
(dict) --
The details for the service registry.
Each service may be associated with one service registry. Multiple service registries for each service are not supported.
When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.
port (integer) --
The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
containerPort (integer) --
The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
status (string) --
The status of the service. The valid values are ACTIVE , DRAINING , or INACTIVE .
desiredCount (integer) --
The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
runningCount (integer) --
The number of tasks in the cluster that are in the RUNNING state.
pendingCount (integer) --
The number of tasks in the cluster that are in the PENDING state.
launchType (string) --
The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.
capacityProviderStrategy (list) --
The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
A capacity provider strategy may contain a maximum of 6 capacity providers.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
platformVersion (string) --
The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn't specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
platformFamily (string) --
The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.
All tasks that run as part of this service must use the same platformFamily value as the service (for example, LINUX ).
taskDefinition (string) --
The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
deploymentConfiguration (dict) --
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker (dict) --
Note
The deployment circuit breaker can only be used for services using the rolling update ( ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable (boolean) --
Determines whether to use the deployment circuit breaker logic for the service.
rollback (boolean) --
Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
minimumHealthyPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.
For services that do not use a load balancer, the following should be noted:
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services are that do use a load balancer, the following should be noted:
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

This field is not required for a "client" Amazon ECS service that's a member of a namespace only to connect to other services within the namespace. An example of this would be a frontend application that accepts incoming requests from either a load balancer that's attached to the service or by other means.
An object selects a port from the task definition, assigns a name for the Cloud Map service, and a list of aliases (endpoints) and ports for client applications to refer to this service.
(dict) --
The Service Connect service object configuration. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
portName (string) --
The portName must match the name of one of the portMappings from all the containers in the task definition of this Amazon ECS service.
discoveryName (string) --
The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.
If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .
clientAliases (list) --
The list of client aliases for this Service Connect service. You use these to assign names that can be used by client applications. The maximum number of client aliases that you can have in this list is 1.
Each alias ("endpoint") is a fully-qualified name and port number that other Amazon ECS tasks ("clients") can use to connect to this service.
Each name and port mapping must be unique within the namespace.
For each ServiceConnectService , you must provide at least one clientAlias with one port .
(dict) --
Each alias ("endpoint") is a fully-qualified name and port number that other tasks ("clients") can use to connect to this service.
Each name and port mapping must be unique within the namespace.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
port (integer) --
The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.
To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
dnsName (string) --
The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.
If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .
To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database , db , or the lowercase name of a database, such as mysql or redis . For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
ingressPortOverride (integer) --
The port number for the Service Connect proxy to listen on.
Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.
In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.
logConfiguration (dict) --
The log configuration for the container. This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run.
By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition. For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Understand the following when specifying a log configuration for your containers.
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent. For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens . For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide .
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.
logDriver (string) --
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
(string) --
(string) --
secretOptions (list) --
The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.
To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.
For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
name (string) --
The name of the secret.
valueFrom (string) --
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide .
Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
serviceConnectResources (list) --
The list of Service Connect resources that are associated with this deployment. Each list entry maps a discovery name to a Cloud Map service name.
(dict) --
The Service Connect resource. Each configuration maps a discovery name to a Cloud Map service name. The data is stored in Cloud Map as part of the Service Connect configuration for each discovery name of this Amazon ECS service.
A task can resolve the dnsName for each of the clientAliases of a service. However a task can't resolve the discovery names. If you want to connect to a service, refer to the ServiceConnectConfiguration of that service for the list of clientAliases that you can use.
discoveryName (string) --
The discovery name of this Service Connect resource.
The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.
If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .
discoveryArn (string) --

managedEBSVolume (dict) --
The configuration for the Amazon EBS volume that Amazon ECS creates and manages on your behalf. These settings are used to create each Amazon EBS volume, with one volume created for each task in the service. The Amazon EBS volumes are visible in your account in the Amazon EC2 console once they are created.
encrypted (boolean) --
Indicates whether the volume should be encrypted. If no value is specified, encryption is turned on by default. This parameter maps 1:1 with the Encrypted parameter of the CreateVolume API in the Amazon EC2 API Reference .
kmsKeyId (string) --
The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference .
Warning
Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.

iops (integer) --
The number of I/O operations per second (IOPS). For gp3 , io1 , and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.
The following are the supported values for each volume type.
gp3 : 3,000 - 16,000 IOPS
io1 : 100 - 64,000 IOPS
io2 : 100 - 256,000 IOPS
This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS . This parameter is not supported for st1 , sc1 , or standard volume types.
This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference .

Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

roleArn (string) --
The ARN of the IAM role that's associated with the service. It allows the Amazon ECS container agent to register container instances with an Elastic Load Balancing load balancer.
events (list) --
The event stream for your service. A maximum of 100 of the latest events are displayed.
(dict) --
The details for an event that's associated with a service.
id (string) --
The ID string for the event.
createdAt (datetime) --
The Unix timestamp for the time when the event was triggered.
message (string) --
The event message.
createdAt (datetime) --
The Unix timestamp for the time when the service was created.
placementConstraints (list) --
The placement constraints for the tasks in the service.
(dict) --
An object representing a constraint on task placement. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide .
Note
If you're using the Fargate launch type, task placement constraints aren't supported.
type (string) --
The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
expression (string) --
A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is distinctInstance . For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .

The placement strategy that determines how tasks for the service are placed.
(dict) --
The task placement strategy for a task or service. For more information, see Task placement strategies in the Amazon Elastic Container Service Developer Guide .
type (string) --
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.
field (string) --
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.
networkConfiguration (dict) --
The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.

schedulingStrategy (string) --
The scheduling strategy to use for the service. For more information, see Services.
There are two service scheduler strategies available.
REPLICA -The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions.
DAEMON -The daemon scheduling strategy deploys exactly one task on each active container instance. This task meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It stop tasks that don't meet the placement constraints.
Note
Fargate tasks don't support the DAEMON scheduling strategy.
deploymentController (dict) --
The deployment controller type the service is using.
type (string) --
The deployment controller type to use.
There are three deployment controller types available:
ECS
The rolling update ( ECS ) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration.
CODE_DEPLOY
The blue/green ( CODE_DEPLOY ) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.
EXTERNAL
The external ( EXTERNAL ) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.
tags (list) --
The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value. You define bot the key and value.
The following basic restrictions apply to tags:
Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
createdBy (string) --
The principal that created the service.
enableECSManagedTags (boolean) --
Determines whether to use Amazon ECS managed tags for the tasks in the service. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide .
propagateTags (string) --
Determines whether to propagate the tags from the task definition or the service to the task. If no value is specified, the tags aren't propagated.
enableExecuteCommand (boolean) --
Determines whether the execute command functionality is turned on for the service. If true , the execute command functionality is turned on for all containers in tasks as part of the service.
{'taskDefinitions': {'volumes': {'configuredAtLaunch': 'boolean'}}}
Deletes one or more task definitions.
You must deregister a task definition revision before you delete it. For more information, see DeregisterTaskDefinition.
When you delete a task definition revision, it is immediately transitions from the INACTIVE to DELETE_IN_PROGRESS . Existing tasks and services that reference a DELETE_IN_PROGRESS task definition revision continue to run without disruption. Existing services that reference a DELETE_IN_PROGRESS task definition revision can still scale up or down by modifying the service's desired count.
You can't use a DELETE_IN_PROGRESS task definition revision to run new tasks or create new services. You also can't update an existing service to reference a DELETE_IN_PROGRESS task definition revision.
A task definition revision will stay in DELETE_IN_PROGRESS status until all the associated tasks and services have been terminated.
When you delete all INACTIVE task definition revisions, the task definition name is not displayed in the console and not returned in the API. If a task definition revisions are in the DELETE_IN_PROGRESS state, the task definition name is displayed in the console and returned in the API. The task definition name is retained by Amazon ECS and the revision is incremented the next time you create a task definition with that name.

Response Structure
(dict) --
taskDefinitions (list) --
The list of deleted task definitions.
(dict) --
The details of a task definition which describes the container and volume definitions of an Amazon Elastic Container Service task. You can specify which Docker images to use, the required resources, and other configurations related to launching the task definition through an Amazon ECS service or task.
taskDefinitionArn (string) --
The full Amazon Resource Name (ARN) of the task definition.
containerDefinitions (list) --
A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide .
(dict) --
Container definitions are used in task definitions to describe the different containers that are launched as part of a task.
name (string) --
The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run.
image (string) --
The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.
Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest . For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE .
Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo ).
Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent ).
Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu ).
repositoryCredentials (dict) --
The private repository authentication credentials to use.
credentialsParameter (string) --
The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note
When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu (integer) --
The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run.
This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.
Note
You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.
Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter isn't required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0 , which Windows interprets as 1% of one CPU.
memory (integer) --
The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.
If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
memoryReservation (integer) --
The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run.
If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.
The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
links (list) --
The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge . The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run.
Note
This parameter is not supported for Windows containers.
Warning
Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
(string) --
portMappings (list) --
The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the awsvpc network mode, only specify the containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Port mappings on Windows use the NetNAT gateway address rather than localhost . There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.
This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to none , then you can't specify port mappings. If the network mode of a task definition is set to host , then host ports must either be undefined or they must match the container port in the port mapping.
Note
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
(dict) --
Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.
If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Most fields of this parameter ( containerPort , hostPort , protocol ) maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to host , host ports must either be undefined or match the container port in the port mapping.
Note
You can't expose the same container port for multiple protocols. If you attempt this, an error is returned.
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses.
containerPort (integer) --
The port number on the container that's bound to the user-specified or automatically assigned host port.
If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort .
If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort . Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.
hostPort (integer) --
The port number on the container instance to reserve for your container.
If you specify a containerPortRange , leave this field empty and the value of the hostPort is set as follows:
For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.
If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort .
If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0 ) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.
The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range . If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.
The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.
protocol (string) --
The protocol used for the port mapping. Valid values are tcp and udp . The default is tcp . protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.
name (string) --
The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.
For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
appProtocol (string) --
The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.
If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.
appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
containerPortRange (string) --
The port number range on the container that's bound to the dynamically mapped host port range.
The following rules apply when you specify a containerPortRange :
You must use either the bridge network mode or the awsvpc network mode.
This parameter is available for both the EC2 and Fargate launch types.
This parameter is available for both the Linux and Windows operating systems.
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package
You can specify a maximum of 100 port ranges per container.
You do not specify a hostPortRange . The value of the hostPortRange is set as follows:
For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
The containerPortRange valid values are between 1 and 65535.
A port can only be included in one port mapping per container.
You cannot specify overlapping port ranges.
The first port in the range must be less than last port in the range.
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see Issue #11185 on the Github website. For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide .
You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.
essential (boolean) --
If the essential parameter of a container is marked as true , and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false , its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.
All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide .
entryPoint (list) --
Warning
Early versions of the Amazon ECS container agent don't properly handle entryPoint parameters. If you have problems using entryPoint , update your container agent or enter your commands and arguments as command array items instead.
The entry point that's passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint.
(string) --
command (list) --
The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd. If there are multiple arguments, each argument is a separated string in the array.
(string) --
environment (list) --
The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run.
Warning
We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.
(dict) --
A key-value pair object.
name (string) --
The name of the key-value pair. For environment variables, this is the name of the environment variable.
value (string) --
The value of the key-value pair. For environment variables, this is the value of the environment variable.
environmentFiles (list) --
A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run.
You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file contains an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored. For more information about the environment variable file syntax, see Declare default environment variables in file.
If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide .
(dict) --
A list of files containing the environment variables to pass to a container. You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file should contain an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored.

If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying environment variables in the Amazon Elastic Container Service Developer Guide .
You must use the following platforms for the Fargate launch type:
Linux platform version 1.4.0 or later.
Windows platform version 1.0.0 or later.
Consider the following when using the Fargate launch type:
The file is handled like a native Docker env-file.

(string) --
devices (list) --
Any host devices to expose to the container. This parameter maps to Devices in the Create a container section of the Docker Remote API and the --device option to docker run.
Note
If you're using tasks that use the Fargate launch type, the devices parameter isn't supported.

(string) --
maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value.
If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
If you're using tasks that use the Fargate launch type, the maxSwap parameter isn't supported.
If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.
swappiness (integer) --
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run.
Note
If you're using tasks that use the Fargate launch type, the swappiness parameter isn't supported.
If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.
secrets (list) --

(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.
To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.
For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
name (string) --
The name of the secret.
valueFrom (string) --
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide .
Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
dependsOn (list) --
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies on other containers in a task definition. When a dependency is defined for container startup, for container shutdown it is reversed.
For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
(dict) --
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
Your Amazon ECS container instances require at least version 1.26.0 of the container agent to use container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
Note
For tasks that use the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
containerName (string) --
The name of a container.
condition (string) --
The dependency condition of the container. The following are the available conditions and their behavior:
START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.
COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.
SUCCESS - This condition is the same as COMPLETE , but it also requires that the container exits with a zero status. This condition can't be set on an essential container.
HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.
startTimeout (integer) --
Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE , SUCCESS , or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state.
Note
When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value.
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
The valid values are 2-120 seconds.
stopTimeout (integer) --
Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
The valid values are 2-120 seconds.

For Linux tasks on EC2, this parameter can be used to reference custom labels for SELinux and AppArmor multi-level security systems.
For any tasks on EC2, this parameter can be used to reference a credential spec file that configures a container for Active Directory authentication. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers in the Amazon Elastic Container Service Developer Guide .
This parameter maps to SecurityOpt in the Create a container section of the Docker Remote API and the --security-opt option to docker run.
Note
The Amazon ECS container agent running on a container instance must register with the ECS_SELINUX_CAPABLE=true or ECS_APPARMOR_CAPABLE=true environment variables before containers placed on that instance can use these security options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
For more information about valid values, see Docker Run Security Configuration.
Valid values: "no-new-privileges" | "apparmor:PROFILE" | "label:value" | "credentialspec:CredentialSpecFilePath"

pseudoTerminal (boolean) --
When this parameter is true , a TTY is allocated. This parameter maps to Tty in the Create a container section of the Docker Remote API and the --tty option to docker run.
dockerLabels (dict) --
A key/value map of labels to add to the container. This parameter maps to Labels in the Create a container section of the Docker Remote API and the --label option to docker run. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
(string) --
(string) --
ulimits (list) --
A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it overrides the default values set by Docker. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type.
Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 4096 .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
This parameter is not supported for Windows containers.
(dict) --
The ulimit settings to pass to the container.
Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 4096 .
You can specify the ulimit settings for a container in a task definition.
name (string) --
The type of the ulimit .
softLimit (integer) --
The soft limit for the ulimit type.
hardLimit (integer) --
The hard limit for the ulimit type.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
logDriver (string) --
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
(string) --
(string) --
secretOptions (list) --
The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.
To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.
For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
name (string) --
The name of the secret.
valueFrom (string) --
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide .
Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
healthCheck (dict) --
The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run.
command (list) --
A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to run the command arguments directly, or CMD-SHELL to run the command with the container's default shell.
When you use the Amazon Web Services Management Console JSON panel, the Command Line Interface, or the APIs, enclose the list of commands in double quotes and brackets.
[ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]
You don't include the double quotes and brackets when you use the Amazon Web Services Management Console.
CMD-SHELL, curl -f http://localhost/ || exit 1
An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in the Create a container section of the Docker Remote API.
(string) --
interval (integer) --
The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.
timeout (integer) --
The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5.
retries (integer) --
The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3.
startPeriod (integer) --
The optional grace period to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You can specify between 0 and 300 seconds. By default, the startPeriod is off.
Note
If a health check succeeds within the startPeriod , then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
systemControls (list) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.
Note
We don't recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. For tasks that use the awsvpc network mode, the container that's started last determines which systemControls parameters take effect. For tasks that use the host network mode, it changes the container instance's namespaced kernel parameters as well as the containers.
Note
This parameter is not supported for Windows containers.
Note
This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
(dict) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run.
We don't recommend that you specify network-related systemControls parameters for multiple containers in a single task. This task also uses either the awsvpc or host network mode. It does it for the following reasons.
For tasks that use the awsvpc network mode, if you set systemControls for any container, it applies to all containers in the task. If you set different systemControls for multiple containers in a single task, the container that's started last determines which systemControls take effect.
For tasks that use the host network mode, the systemControls parameter applies to the container instance's kernel parameter and that of all containers of any tasks running on that container instance.
namespace (string) --
The namespaced kernel parameter to set a value for.
value (string) --
The namespaced kernel parameter to set a value for.
Valid IPC namespace values: "kernel.msgmax" | "kernel.msgmnb" | "kernel.msgmni" | "kernel.sem" | "kernel.shmall" | "kernel.shmmax" | "kernel.shmmni" | "kernel.shm_rmid_forced" , and Sysctls that start with "fs.mqueue.*"
Valid network namespace values: Sysctls that start with "net.*"
All of these values are supported by Fargate.
resourceRequirements (list) --
The type and amount of a resource to assign to a container. The only supported resource is a GPU.
(dict) --
The type and amount of a resource to assign to a container. The supported resource types are GPUs and Elastic Inference accelerators. For more information, see Working with GPUs on Amazon ECS or Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide
value (string) --
The value for the specified resource type.
If the GPU type is used, the value is the number of physical GPUs the Amazon ECS container agent reserves for the container. The number of GPUs that's reserved for all containers in a task can't exceed the number of available GPUs on the container instance that the task is launched on.
If the InferenceAccelerator type is used, the value matches the deviceName for an InferenceAccelerator specified in a task definition.
type (string) --
The type of resource to assign to a container. The supported values are GPU or InferenceAccelerator .
firelensConfiguration (dict) --
The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide .
type (string) --
The log router to use. The valid values are fluentd or fluentbit .
options (dict) --
The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"} . For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide .
Note
Tasks hosted on Fargate only support the file configuration file type.
(string) --
(string) --
credentialSpecs (list) --
A list of ARNs in SSM or Amazon S3 to a credential spec ( CredSpec ) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions . The maximum number of ARNs is 1.
There are two formats for each ARN.
credentialspecdomainless:MyARN
You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.
Each task that runs on any container instance can join different domains.
You can use this format without joining the container instance to a domain.
credentialspec:MyARN
You use credentialspec:MyARN to provide a CredSpec for a single domain.
You must join the container instance to the domain before you start any tasks that use this task definition.
In both formats, replace MyARN with the ARN in SSM or Amazon S3.
If you provide a credentialspecdomainless:MyARN , the credspec must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.
(string) --
family (string) --
The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.
A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
taskRoleArn (string) --
The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide .
IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code to use the feature. For more information, see Windows IAM roles for tasks in the Amazon Elastic Container Service Developer Guide .
executionRoleArn (string) --
The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide .
networkMode (string) --
The Docker networking mode to use for the containers in the task. The valid values are none , bridge , awsvpc , and host . If no network mode is specified, the default is bridge .
For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none , you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.
With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.
Warning
When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.
If the network mode is awsvpc , the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .
If the network mode is host , you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.
For more information, see Network settings in the Docker run reference .
revision (integer) --
The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is 1 . Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.
volumes (list) --
The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide .
Note
The host and sourcePath parameters aren't supported for tasks run on Fargate.
(dict) --
The data volume configuration for tasks launched using this task definition. Specifying a volume configuration in a task definition is optional. The volume configuration may contain multiple volumes but only one volume configured at launch is supported. Each volume defined in the volume configuration may only specify a name and one of either configuredAtLaunch , dockerVolumeConfiguration , efsVolumeConfiguration , fsxWindowsFileServerVolumeConfiguration , or host . If an empty volume configuration is specified, by default Amazon ECS uses a host volume. For more information, see Using data volumes in tasks.
name (string) --
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.
When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task.
For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition.
When a volume is using the efsVolumeConfiguration , the name is required.
host (dict) --
This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.
Windows containers can mount whole directories on the same drive as $env:ProgramData . Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\ , but not D:\my\path:C:\my\path or D:\:C:\my\path .
sourcePath (string) --
When the host parameter is used, specify a sourcePath to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
If you're using the Fargate launch type, the sourcePath parameter is not supported.
dockerVolumeConfiguration (dict) --
This parameter is specified when you use Docker volumes.
Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.
Note
Docker volumes aren't supported by tasks run on Fargate.
scope (string) --
The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.
autoprovision (boolean) --
If this value is true , the Docker volume is created if it doesn't already exist.
Note
This field is only used if the scope is shared .
driver (string) --
The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. For more information, see Docker plugin discovery. This parameter maps to Driver in the Create a volume section of the Docker Remote API and the xxdriver option to docker volume create.
driverOpts (dict) --
A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the Create a volume section of the Docker Remote API and the xxopt option to docker volume create.
(string) --
(string) --
labels (dict) --
Custom metadata to add to your Docker volume. This parameter maps to Labels in the Create a volume section of the Docker Remote API and the xxlabel option to docker volume create.
(string) --
(string) --
efsVolumeConfiguration (dict) --
This parameter is specified when you use an Amazon Elastic File System file system for task storage.
fileSystemId (string) --
The Amazon EFS file system ID to use.
rootDirectory (string) --
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.
transitEncryption (string) --
Determines whether to use encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be turned on if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide .
transitEncryptionPort (integer) --
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS mount helper in the Amazon Elastic File System User Guide .
authorizationConfig (dict) --
The authorization configuration details for the Amazon EFS file system.

requiresAttributes (list) --
The container instance attributes required by your task. When an Amazon EC2 instance is registered to your cluster, the Amazon ECS container agent assigns some standard attributes to the instance. You can apply custom attributes. These are specified as key-value pairs using the Amazon ECS console or the PutAttributes API. These attributes are used when determining task placement for tasks hosted on Amazon EC2 instances. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide .
Note
This parameter isn't supported for tasks run on Fargate.

inferenceAccelerators (list) --
The Elastic Inference accelerator that's associated with the task.
(dict) --
Details on an Elastic Inference accelerator. For more information, see Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide .
deviceName (string) --
The Elastic Inference accelerator device name. The deviceName must also be referenced in a container definition as a ResourceRequirement.
deviceType (string) --
The Elastic Inference accelerator type to use.
pidMode (string) --
The process namespace to use for the containers in the task. The valid values are host or task . On Fargate for Linux containers, the only valid value is task . For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.
If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.
If task is specified, all containers within the specified task share the same process namespace.
If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference .
If the host PID mode is used, there's a heightened risk of undesired process namespace exposure. For more information, see Docker security.
Note
This parameter is not supported for Windows containers.
Note
This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
ipcMode (string) --
The IPC resource namespace to use for the containers in the task. The valid values are host , task , or none . If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference .
If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security.
If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide .
For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.
For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task.
Note
This parameter is not supported for Windows containers or tasks run on Fargate.
proxyConfiguration (dict) --

{'taskDefinition': {'volumes': {'configuredAtLaunch': 'boolean'}}}
Deregisters the specified task definition by family and revision. Upon deregistration, the task definition is marked as INACTIVE . Existing tasks and services that reference an INACTIVE task definition continue to run without disruption. Existing services that reference an INACTIVE task definition can still scale up or down by modifying the service's desired count. If you want to delete a task definition revision, you must first deregister the task definition revision.
You can't use an INACTIVE task definition to run new tasks or create new services, and you can't update an existing service to reference an INACTIVE task definition. However, there may be up to a 10-minute window following deregistration where these restrictions have not yet taken effect.
Note
At this time, INACTIVE task definitions remain discoverable in your account indefinitely. However, this behavior is subject to change in the future. We don't recommend that you rely on INACTIVE task definitions persisting beyond the lifecycle of any associated tasks and services.
You must deregister a task definition revision before you delete it. For more information, see DeleteTaskDefinitions.

Response Structure
(dict) --
taskDefinition (dict) --
The full description of the deregistered task.
taskDefinitionArn (string) --
The full Amazon Resource Name (ARN) of the task definition.
containerDefinitions (list) --
A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide .
(dict) --
Container definitions are used in task definitions to describe the different containers that are launched as part of a task.
name (string) --
The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run.
image (string) --
The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.
Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest . For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE .
Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo ).
Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent ).
Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu ).
repositoryCredentials (dict) --
The private repository authentication credentials to use.
credentialsParameter (string) --
The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note
When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu (integer) --
The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run.
This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.
Note
You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.
Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter isn't required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0 , which Windows interprets as 1% of one CPU.
memory (integer) --
The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.
If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
memoryReservation (integer) --
The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run.
If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.
The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.

The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge . The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run.
Note
This parameter is not supported for Windows containers.
Warning
Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
(string) --
portMappings (list) --
The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the awsvpc network mode, only specify the containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Port mappings on Windows use the NetNAT gateway address rather than localhost . There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.
This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to none , then you can't specify port mappings. If the network mode of a task definition is set to host , then host ports must either be undefined or they must match the container port in the port mapping.
Note
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
(dict) --
Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.
If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Most fields of this parameter ( containerPort , hostPort , protocol ) maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to host , host ports must either be undefined or match the container port in the port mapping.
Note
You can't expose the same container port for multiple protocols. If you attempt this, an error is returned.
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses.
containerPort (integer) --
The port number on the container that's bound to the user-specified or automatically assigned host port.
If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort .
If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort . Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.
hostPort (integer) --
The port number on the container instance to reserve for your container.
If you specify a containerPortRange , leave this field empty and the value of the hostPort is set as follows:
For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.
If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort .
If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0 ) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.
The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range . If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.
The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.
protocol (string) --
The protocol used for the port mapping. Valid values are tcp and udp . The default is tcp . protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.
name (string) --
The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.
For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
appProtocol (string) --
The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.
If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.
appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
containerPortRange (string) --
The port number range on the container that's bound to the dynamically mapped host port range.
The following rules apply when you specify a containerPortRange :
You must use either the bridge network mode or the awsvpc network mode.
This parameter is available for both the EC2 and Fargate launch types.
This parameter is available for both the Linux and Windows operating systems.
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package
You can specify a maximum of 100 port ranges per container.
You do not specify a hostPortRange . The value of the hostPortRange is set as follows:
For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
The containerPortRange valid values are between 1 and 65535.
A port can only be included in one port mapping per container.
You cannot specify overlapping port ranges.
The first port in the range must be less than last port in the range.
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see Issue #11185 on the Github website. For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide .
You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.
essential (boolean) --
If the essential parameter of a container is marked as true , and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false , its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.
All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide .
entryPoint (list) --
Warning
Early versions of the Amazon ECS container agent don't properly handle entryPoint parameters. If you have problems using entryPoint , update your container agent or enter your commands and arguments as command array items instead.

Lines beginning with # are treated as comments and are ignored. For more information about the environment variable file syntax, see Declare default environment variables in file.
If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide .

For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide .
Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
dependsOn (list) --
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies on other containers in a task definition. When a dependency is defined for container startup, for container shutdown it is reversed.
For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
(dict) --
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
Your Amazon ECS container instances require at least version 1.26.0 of the container agent to use container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .

For tasks that use the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
containerName (string) --
The name of a container.
condition (string) --
The dependency condition of the container. The following are the available conditions and their behavior:
START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.
COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.
SUCCESS - This condition is the same as COMPLETE , but it also requires that the container exits with a zero status. This condition can't be set on an essential container.
HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.
startTimeout (integer) --
Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE , SUCCESS , or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state.
Note
When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value.
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
The valid values are 2-120 seconds.
stopTimeout (integer) --
Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
The valid values are 2-120 seconds.

(string) --
interactive (boolean) --
When this parameter is true , you can deploy containerized applications that require stdin or a tty to be allocated. This parameter maps to OpenStdin in the Create a container section of the Docker Remote API and the --interactive option to docker run.
pseudoTerminal (boolean) --
When this parameter is true , a TTY is allocated. This parameter maps to Tty in the Create a container section of the Docker Remote API and the --tty option to docker run.
dockerLabels (dict) --
A key/value map of labels to add to the container. This parameter maps to Labels in the Create a container section of the Docker Remote API and the --label option to docker run. This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
(string) --
(string) --
ulimits (list) --
A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it overrides the default values set by Docker. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type.
Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 4096 .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
This parameter is not supported for Windows containers.
(dict) --
The ulimit settings to pass to the container.
Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 4096 .
You can specify the ulimit settings for a container in a task definition.
name (string) --
The type of the ulimit .
softLimit (integer) --
The soft limit for the ulimit type.
hardLimit (integer) --
The hard limit for the ulimit type.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
logDriver (string) --
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
(string) --
(string) --
secretOptions (list) --
The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.
To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.
For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
name (string) --
The name of the secret.
valueFrom (string) --
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide .
Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
healthCheck (dict) --
The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run.
command (list) --
A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to run the command arguments directly, or CMD-SHELL to run the command with the container's default shell.
When you use the Amazon Web Services Management Console JSON panel, the Command Line Interface, or the APIs, enclose the list of commands in double quotes and brackets.
[ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]
You don't include the double quotes and brackets when you use the Amazon Web Services Management Console.
CMD-SHELL, curl -f http://localhost/ || exit 1
An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in the Create a container section of the Docker Remote API.
(string) --
interval (integer) --
The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.
timeout (integer) --
The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5.
retries (integer) --
The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3.
startPeriod (integer) --
The optional grace period to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You can specify between 0 and 300 seconds. By default, the startPeriod is off.
Note
If a health check succeeds within the startPeriod , then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
systemControls (list) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.
Note
We don't recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. For tasks that use the awsvpc network mode, the container that's started last determines which systemControls parameters take effect. For tasks that use the host network mode, it changes the container instance's namespaced kernel parameters as well as the containers.
Note
This parameter is not supported for Windows containers.
Note
This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
(dict) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run.
We don't recommend that you specify network-related systemControls parameters for multiple containers in a single task. This task also uses either the awsvpc or host network mode. It does it for the following reasons.
For tasks that use the awsvpc network mode, if you set systemControls for any container, it applies to all containers in the task. If you set different systemControls for multiple containers in a single task, the container that's started last determines which systemControls take effect.
For tasks that use the host network mode, the systemControls parameter applies to the container instance's kernel parameter and that of all containers of any tasks running on that container instance.
namespace (string) --
The namespaced kernel parameter to set a value for.
value (string) --
The namespaced kernel parameter to set a value for.
Valid IPC namespace values: "kernel.msgmax" | "kernel.msgmnb" | "kernel.msgmni" | "kernel.sem" | "kernel.shmall" | "kernel.shmmax" | "kernel.shmmni" | "kernel.shm_rmid_forced" , and Sysctls that start with "fs.mqueue.*"
Valid network namespace values: Sysctls that start with "net.*"
All of these values are supported by Fargate.
resourceRequirements (list) --
The type and amount of a resource to assign to a container. The only supported resource is a GPU.
(dict) --
The type and amount of a resource to assign to a container. The supported resource types are GPUs and Elastic Inference accelerators. For more information, see Working with GPUs on Amazon ECS or Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide
value (string) --
The value for the specified resource type.
If the GPU type is used, the value is the number of physical GPUs the Amazon ECS container agent reserves for the container. The number of GPUs that's reserved for all containers in a task can't exceed the number of available GPUs on the container instance that the task is launched on.
If the InferenceAccelerator type is used, the value matches the deviceName for an InferenceAccelerator specified in a task definition.
type (string) --
The type of resource to assign to a container. The supported values are GPU or InferenceAccelerator .
firelensConfiguration (dict) --
The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide .
type (string) --
The log router to use. The valid values are fluentd or fluentbit .
options (dict) --
The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"} . For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide .
Note
Tasks hosted on Fargate only support the file configuration file type.
(string) --
(string) --
credentialSpecs (list) --
A list of ARNs in SSM or Amazon S3 to a credential spec ( CredSpec ) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions . The maximum number of ARNs is 1.
There are two formats for each ARN.
credentialspecdomainless:MyARN
You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.
Each task that runs on any container instance can join different domains.
You can use this format without joining the container instance to a domain.
credentialspec:MyARN
You use credentialspec:MyARN to provide a CredSpec for a single domain.
You must join the container instance to the domain before you start any tasks that use this task definition.
In both formats, replace MyARN with the ARN in SSM or Amazon S3.
If you provide a credentialspecdomainless:MyARN , the credspec must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.
(string) --
family (string) --
The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.
A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
taskRoleArn (string) --
The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide .
IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code to use the feature. For more information, see Windows IAM roles for tasks in the Amazon Elastic Container Service Developer Guide .
executionRoleArn (string) --
The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide .
networkMode (string) --
The Docker networking mode to use for the containers in the task. The valid values are none , bridge , awsvpc , and host . If no network mode is specified, the default is bridge .
For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none , you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.
With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.
Warning
When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.
If the network mode is awsvpc , the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .
If the network mode is host , you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.
For more information, see Network settings in the Docker run reference .
revision (integer) --
The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is 1 . Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.
volumes (list) --
The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide .
Note
The host and sourcePath parameters aren't supported for tasks run on Fargate.
(dict) --
The data volume configuration for tasks launched using this task definition. Specifying a volume configuration in a task definition is optional. The volume configuration may contain multiple volumes but only one volume configured at launch is supported. Each volume defined in the volume configuration may only specify a name and one of either configuredAtLaunch , dockerVolumeConfiguration , efsVolumeConfiguration , fsxWindowsFileServerVolumeConfiguration , or host . If an empty volume configuration is specified, by default Amazon ECS uses a host volume. For more information, see Using data volumes in tasks.
name (string) --
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.
When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task.
For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition.
When a volume is using the efsVolumeConfiguration , the name is required.
host (dict) --
This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.
Windows containers can mount whole directories on the same drive as $env:ProgramData . Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\ , but not D:\my\path:C:\my\path or D:\:C:\my\path .
sourcePath (string) --
When the host parameter is used, specify a sourcePath to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
If you're using the Fargate launch type, the sourcePath parameter is not supported.
dockerVolumeConfiguration (dict) --
This parameter is specified when you use Docker volumes.
Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.
Note
Docker volumes aren't supported by tasks run on Fargate.
scope (string) --
The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.
autoprovision (boolean) --
If this value is true , the Docker volume is created if it doesn't already exist.
Note
This field is only used if the scope is shared .
driver (string) --
The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. For more information, see Docker plugin discovery. This parameter maps to Driver in the Create a volume section of the Docker Remote API and the xxdriver option to docker volume create.
driverOpts (dict) --
A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the Create a volume section of the Docker Remote API and the xxopt option to docker volume create.
(string) --
(string) --
labels (dict) --

(string) --
efsVolumeConfiguration (dict) --
This parameter is specified when you use an Amazon Elastic File System file system for task storage.
fileSystemId (string) --
The Amazon EFS file system ID to use.
rootDirectory (string) --
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.
transitEncryption (string) --
Determines whether to use encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be turned on if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide .
transitEncryptionPort (integer) --
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS mount helper in the Amazon Elastic File System User Guide .
authorizationConfig (dict) --
The authorization configuration details for the Amazon EFS file system.
accessPointId (string) --
The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which will enforce the path set on the EFS access point. If an access point is used, transit encryption must be on in the EFSVolumeConfiguration . For more information, see Working with Amazon EFS access points in the Amazon Elastic File System User Guide .
iam (string) --
Determines whether to use the Amazon ECS task role defined in a task definition when mounting the Amazon EFS file system. If it is turned on, transit encryption must be turned on in the EFSVolumeConfiguration . If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS access points in the Amazon Elastic Container Service Developer Guide .
fsxWindowsFileServerVolumeConfiguration (dict) --
This parameter is specified when you use Amazon FSx for Windows File Server file system for task storage.
fileSystemId (string) --
The Amazon FSx for Windows File Server file system ID to use.
rootDirectory (string) --
The directory within the Amazon FSx for Windows File Server file system to mount as the root directory inside the host.
authorizationConfig (dict) --
The authorization configuration details for the Amazon FSx for Windows File Server file system.
credentialsParameter (string) --
The authorization credential option to use. The authorization credential options can be provided using either the Amazon Resource Name (ARN) of an Secrets Manager secret or SSM Parameter Store parameter. The ARN refers to the stored credentials.
domain (string) --
A fully qualified domain name hosted by an Directory Service Managed Microsoft AD (Active Directory) or self-hosted AD on Amazon EC2.
configuredAtLaunch (boolean) --
Indicates whether the volume should be configured at launch time. This is used to create Amazon EBS volumes for standalone tasks or tasks created as part of a service. Each task definition revision may only have one volume configured at launch in the volume configuration.
To configure a volume at launch time, use this task definition revision and specify a volumeConfigurations object when calling the CreateService , UpdateService , RunTask or StartTask APIs.
status (string) --
The status of the task definition.
requiresAttributes (list) --
The container instance attributes required by your task. When an Amazon EC2 instance is registered to your cluster, the Amazon ECS container agent assigns some standard attributes to the instance. You can apply custom attributes. These are specified as key-value pairs using the Amazon ECS console or the PutAttributes API. These attributes are used when determining task placement for tasks hosted on Amazon EC2 instances. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide .
Note
This parameter isn't supported for tasks run on Fargate.
(dict) --
An attribute is a name-value pair that's associated with an Amazon ECS object. Use attributes to extend the Amazon ECS data model by adding custom metadata to your resources. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide .
name (string) --
The name of the attribute. The name must contain between 1 and 128 characters. The name may contain letters (uppercase and lowercase), numbers, hyphens (-), underscores (_), forward slashes (/), back slashes (), or periods (.).

It can contain letters (uppercase and lowercase), numbers, hyphens (-), underscores (_), periods (.), at signs (@), forward slashes (/), back slashes (), colons (:), or spaces. The value can't start or end with a space.
targetType (string) --
The type of the target to attach the attribute with. This parameter is required if you use the short form ID for a resource instead of the full ARN.
targetId (string) --
The ID of the target. You can specify the short form ID for a resource or the full Amazon Resource Name (ARN).
placementConstraints (list) --
An array of placement constraint objects to use for tasks.
Note
This parameter isn't supported for tasks run on Fargate.

deviceType (string) --
The Elastic Inference accelerator type to use.
pidMode (string) --
The process namespace to use for the containers in the task. The valid values are host or task . On Fargate for Linux containers, the only valid value is task . For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.
If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.
If task is specified, all containers within the specified task share the same process namespace.
If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference .
If the host PID mode is used, there's a heightened risk of undesired process namespace exposure. For more information, see Docker security.
Note
This parameter is not supported for Windows containers.
Note
This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
ipcMode (string) --
The IPC resource namespace to use for the containers in the task. The valid values are host , task , or none . If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference .
If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security.
If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide .
For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.
For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task.
Note
This parameter is not supported for Windows containers or tasks run on Fargate.
proxyConfiguration (dict) --
The configuration details for the App Mesh proxy.
Your Amazon ECS container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to use a proxy configuration. If your container instances are launched from the Amazon ECS optimized AMI version 20190301 or later, they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
type (string) --
The proxy type. The only supported value is APPMESH .
containerName (string) --
The name of the container that will serve as the App Mesh proxy.
properties (list) --
The set of network configuration parameters to provide the Container Network Interface (CNI) plugin, specified as key-value pairs.
IgnoredUID - (Required) The user ID (UID) of the proxy container as defined by the user parameter in a container definition. This is used to ensure the proxy ignores its own traffic. If IgnoredGID is specified, this field can be empty.
IgnoredGID - (Required) The group ID (GID) of the proxy container as defined by the user parameter in a container definition. This is used to ensure the proxy ignores its own traffic. If IgnoredUID is specified, this field can be empty.
AppPorts - (Required) The list of ports that the application uses. Network traffic to these ports is forwarded to the ProxyIngressPort and ProxyEgressPort .
ProxyIngressPort - (Required) Specifies the port that incoming traffic to the AppPorts is directed to.
ProxyEgressPort - (Required) Specifies the port that outgoing traffic from the AppPorts is directed to.
EgressIgnoredPorts - (Required) The egress traffic going to the specified ports is ignored and not redirected to the ProxyEgressPort . It can be an empty list.
EgressIgnoredIPs - (Required) The egress traffic going to the specified IP addresses is ignored and not redirected to the ProxyEgressPort . It can be an empty list.

Response Structure
(dict) --
services (list) --
The list of services described.
(dict) --
Details on a service within a cluster.
serviceArn (string) --
The ARN that identifies the service. For more information about the ARN format, see Amazon Resource Name (ARN) in the Amazon ECS Developer Guide .
serviceName (string) --
The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster. However, you can have similarly named services in multiple clusters within a Region or across multiple Regions.
clusterArn (string) --
The Amazon Resource Name (ARN) of the cluster that hosts the service.
loadBalancers (list) --
A list of Elastic Load Balancing load balancer objects. It contains the load balancer name, the container name, and the container port to access from the load balancer. The container name is as it appears in a container definition.
(dict) --
The load balancer configuration to use with a service or task set.
When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.
We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.
A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details for the service discovery registries to assign to this service. For more information, see Service Discovery.
(dict) --
The details for the service registry.
Each service may be associated with one service registry. Multiple service registries for each service are not supported.
When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.
port (integer) --
The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
containerPort (integer) --
The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
status (string) --
The status of the service. The valid values are ACTIVE , DRAINING , or INACTIVE .
desiredCount (integer) --
The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
runningCount (integer) --
The number of tasks in the cluster that are in the RUNNING state.
pendingCount (integer) --
The number of tasks in the cluster that are in the PENDING state.
launchType (string) --
The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.
capacityProviderStrategy (list) --
The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
A capacity provider strategy may contain a maximum of 6 capacity providers.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
platformVersion (string) --
The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn't specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
platformFamily (string) --
The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.
All tasks that run as part of this service must use the same platformFamily value as the service (for example, LINUX ).
taskDefinition (string) --
The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
deploymentConfiguration (dict) --
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker (dict) --
Note
The deployment circuit breaker can only be used for services using the rolling update ( ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable (boolean) --
Determines whether to use the deployment circuit breaker logic for the service.
rollback (boolean) --
Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
minimumHealthyPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.
For services that do not use a load balancer, the following should be noted:
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services are that do use a load balancer, the following should be noted:
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.
alarms (dict) --
Information about the CloudWatch alarms.
alarmNames (list) --
One or more CloudWatch alarm names. Use a "," to separate the alarms.
(string) --
enable (boolean) --
Determines whether to use the CloudWatch alarm option in the service deployment process.
rollback (boolean) --
Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
taskSets (list) --
Information about a set of Amazon ECS tasks in either an CodeDeploy or an EXTERNAL deployment. An Amazon ECS task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.
(dict) --
Information about a set of Amazon ECS tasks in either an CodeDeploy or an EXTERNAL deployment. An Amazon ECS task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.
id (string) --
The ID of the task set.
taskSetArn (string) --
The Amazon Resource Name (ARN) of the task set.
serviceArn (string) --
The Amazon Resource Name (ARN) of the service the task set exists in.
clusterArn (string) --
The Amazon Resource Name (ARN) of the cluster that the service that hosts the task set exists in.
startedBy (string) --
The tag specified when a task set is started. If an CodeDeploy deployment created the task set, the startedBy parameter is CODE_DEPLOY . If an external deployment created the task set, the startedBy field isn't used.
externalId (string) --
The external ID associated with the task set.
If an CodeDeploy deployment created a task set, the externalId parameter contains the CodeDeploy deployment ID.
If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.
status (string) --
The status of the task set. The following describes each state.
PRIMARY
The task set is serving production traffic.
ACTIVE
The task set isn't serving production traffic.
DRAINING
The tasks in the task set are being stopped, and their corresponding targets are being deregistered from their target group.
taskDefinition (string) --
The task definition that the task set is using.
computedDesiredCount (integer) --
The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.
pendingCount (integer) --
The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it's restarted after being in the STOPPED state.

capacityProviderStrategy (list) --
The capacity provider strategy that are associated with the task set.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
A capacity provider strategy may contain a maximum of 6 capacity providers.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --

loadBalancers (list) --
Details on a load balancer that are used with a task set.
(dict) --
The load balancer configuration to use with a service or task set.
When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.
We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.
A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details for the service discovery registries to assign to this task set. For more information, see Service discovery.
(dict) --
The details for the service registry.
Each service may be associated with one service registry. Multiple service registries for each service are not supported.
When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.

containerName (string) --
The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
containerPort (integer) --
The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

runningCount (integer) --
The number of tasks in the deployment that are in the RUNNING status.
failedTasks (integer) --
The number of consecutively failed tasks in the deployment. A task is considered a failure if the service scheduler can't launch the task, the task doesn't transition to a RUNNING state, or if it fails any of its defined health checks and is stopped.
Note
Once a service deployment has one or more successfully running tasks, the failed task count resets to zero and stops being evaluated.
createdAt (datetime) --
The Unix timestamp for the time when the service deployment was created.
updatedAt (datetime) --
The Unix timestamp for the time when the service deployment was last updated.
capacityProviderStrategy (list) --
The capacity provider strategy that the deployment is using.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
A capacity provider strategy may contain a maximum of 6 capacity providers.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

Each alias ("endpoint") is a fully-qualified name and port number that other Amazon ECS tasks ("clients") can use to connect to this service.
Each name and port mapping must be unique within the namespace.
For each ServiceConnectService , you must provide at least one clientAlias with one port .
(dict) --
Each alias ("endpoint") is a fully-qualified name and port number that other tasks ("clients") can use to connect to this service.
Each name and port mapping must be unique within the namespace.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
port (integer) --
The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.
To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
dnsName (string) --
The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.
If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .
To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database , db , or the lowercase name of a database, such as mysql or redis . For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
ingressPortOverride (integer) --
The port number for the Service Connect proxy to listen on.
Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.
In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.
logConfiguration (dict) --
The log configuration for the container. This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run.
By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition. For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Understand the following when specifying a log configuration for your containers.
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent. For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens . For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide .
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.
logDriver (string) --
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance.

Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
serviceConnectResources (list) --
The list of Service Connect resources that are associated with this deployment. Each list entry maps a discovery name to a Cloud Map service name.
(dict) --
The Service Connect resource. Each configuration maps a discovery name to a Cloud Map service name. The data is stored in Cloud Map as part of the Service Connect configuration for each discovery name of this Amazon ECS service.
A task can resolve the dnsName for each of the clientAliases of a service. However a task can't resolve the discovery names. If you want to connect to a service, refer to the ServiceConnectConfiguration of that service for the list of clientAliases that you can use.
discoveryName (string) --
The discovery name of this Service Connect resource.
The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

id (string) --
The ID string for the event.
createdAt (datetime) --
The Unix timestamp for the time when the event was triggered.
message (string) --
The event message.
createdAt (datetime) --
The Unix timestamp for the time when the service was created.
placementConstraints (list) --
The placement constraints for the tasks in the service.
(dict) --
An object representing a constraint on task placement. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide .
Note
If you're using the Fargate launch type, task placement constraints aren't supported.
type (string) --
The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
expression (string) --
A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is distinctInstance . For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .
placementStrategy (list) --
The placement strategy that determines how tasks for the service are placed.
(dict) --
The task placement strategy for a task or service. For more information, see Task placement strategies in the Amazon Elastic Container Service Developer Guide .
type (string) --
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.
field (string) --
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.
networkConfiguration (dict) --
The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.
awsvpcConfiguration (dict) --
The VPC subnets and security groups that are associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
subnets (list) --
The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per AwsVpcConfiguration .
Note
All specified subnets must be from the same VPC.
(string) --
securityGroups (list) --
The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
(string) --
assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
healthCheckGracePeriodSeconds (integer) --
The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started.
schedulingStrategy (string) --
The scheduling strategy to use for the service. For more information, see Services.
There are two service scheduler strategies available.
REPLICA -The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions.
DAEMON -The daemon scheduling strategy deploys exactly one task on each active container instance. This task meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It stop tasks that don't meet the placement constraints.
Note
Fargate tasks don't support the DAEMON scheduling strategy.
deploymentController (dict) --
The deployment controller type the service is using.
type (string) --
The deployment controller type to use.
There are three deployment controller types available:
ECS
The rolling update ( ECS ) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration.
CODE_DEPLOY
The blue/green ( CODE_DEPLOY ) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.
EXTERNAL
The external ( EXTERNAL ) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.
tags (list) --
The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value. You define bot the key and value.
The following basic restrictions apply to tags:
Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

Response Structure
(dict) --
taskDefinition (dict) --
The full task definition description.
taskDefinitionArn (string) --
The full Amazon Resource Name (ARN) of the task definition.
containerDefinitions (list) --
A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide .
(dict) --
Container definitions are used in task definitions to describe the different containers that are launched as part of a task.
name (string) --
The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run.
image (string) --
The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.
Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest . For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE .
Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo ).
Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent ).
Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu ).
repositoryCredentials (dict) --
The private repository authentication credentials to use.
credentialsParameter (string) --
The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note
When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu (integer) --
The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run.
This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.
Note
You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.
Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter isn't required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0 , which Windows interprets as 1% of one CPU.
memory (integer) --
The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.
If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
memoryReservation (integer) --
The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run.
If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.
The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
links (list) --
The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge . The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run.
Note
This parameter is not supported for Windows containers.
Warning
Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
(string) --
portMappings (list) --
The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the awsvpc network mode, only specify the containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Port mappings on Windows use the NetNAT gateway address rather than localhost . There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.
This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to none , then you can't specify port mappings. If the network mode of a task definition is set to host , then host ports must either be undefined or they must match the container port in the port mapping.
Note
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
(dict) --
Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.
If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Most fields of this parameter ( containerPort , hostPort , protocol ) maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to host , host ports must either be undefined or match the container port in the port mapping.
Note
You can't expose the same container port for multiple protocols. If you attempt this, an error is returned.
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses.
containerPort (integer) --
The port number on the container that's bound to the user-specified or automatically assigned host port.
If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort .
If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort . Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.
hostPort (integer) --
The port number on the container instance to reserve for your container.
If you specify a containerPortRange , leave this field empty and the value of the hostPort is set as follows:
For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.
If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort .
If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0 ) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.
The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range . If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.
The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.
protocol (string) --
The protocol used for the port mapping. Valid values are tcp and udp . The default is tcp . protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.
name (string) --
The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.
For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
appProtocol (string) --
The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.
If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.
appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
containerPortRange (string) --
The port number range on the container that's bound to the dynamically mapped host port range.
The following rules apply when you specify a containerPortRange :
You must use either the bridge network mode or the awsvpc network mode.
This parameter is available for both the EC2 and Fargate launch types.
This parameter is available for both the Linux and Windows operating systems.
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package
You can specify a maximum of 100 port ranges per container.
You do not specify a hostPortRange . The value of the hostPortRange is set as follows:
For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
The containerPortRange valid values are between 1 and 65535.
A port can only be included in one port mapping per container.
You cannot specify overlapping port ranges.
The first port in the range must be less than last port in the range.
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see Issue #11185 on the Github website. For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide .
You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.
essential (boolean) --
If the essential parameter of a container is marked as true , and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false , its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.
All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide .

START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.
COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.
SUCCESS - This condition is the same as COMPLETE , but it also requires that the container exits with a zero status. This condition can't be set on an essential container.
HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.
startTimeout (integer) --
Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE , SUCCESS , or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state.
Note
When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value.
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init .

stopTimeout (integer) --
Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package.

An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in the Create a container section of the Docker Remote API.
(string) --
interval (integer) --
The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.
timeout (integer) --
The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5.
retries (integer) --
The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3.
startPeriod (integer) --
The optional grace period to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You can specify between 0 and 300 seconds. By default, the startPeriod is off.
Note
If a health check succeeds within the startPeriod , then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
systemControls (list) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.
Note
We don't recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. For tasks that use the awsvpc network mode, the container that's started last determines which systemControls parameters take effect. For tasks that use the host network mode, it changes the container instance's namespaced kernel parameters as well as the containers.
Note
This parameter is not supported for Windows containers.
Note
This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
(dict) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run.
We don't recommend that you specify network-related systemControls parameters for multiple containers in a single task. This task also uses either the awsvpc or host network mode. It does it for the following reasons.
For tasks that use the awsvpc network mode, if you set systemControls for any container, it applies to all containers in the task. If you set different systemControls for multiple containers in a single task, the container that's started last determines which systemControls take effect.
For tasks that use the host network mode, the systemControls parameter applies to the container instance's kernel parameter and that of all containers of any tasks running on that container instance.
namespace (string) --
The namespaced kernel parameter to set a value for.
value (string) --
The namespaced kernel parameter to set a value for.
Valid IPC namespace values: "kernel.msgmax" | "kernel.msgmnb" | "kernel.msgmni" | "kernel.sem" | "kernel.shmall" | "kernel.shmmax" | "kernel.shmmni" | "kernel.shm_rmid_forced" , and Sysctls that start with "fs.mqueue.*"
Valid network namespace values: Sysctls that start with "net.*"
All of these values are supported by Fargate.
resourceRequirements (list) --
The type and amount of a resource to assign to a container. The only supported resource is a GPU.
(dict) --
The type and amount of a resource to assign to a container. The supported resource types are GPUs and Elastic Inference accelerators. For more information, see Working with GPUs on Amazon ECS or Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide
value (string) --
The value for the specified resource type.
If the GPU type is used, the value is the number of physical GPUs the Amazon ECS container agent reserves for the container. The number of GPUs that's reserved for all containers in a task can't exceed the number of available GPUs on the container instance that the task is launched on.
If the InferenceAccelerator type is used, the value matches the deviceName for an InferenceAccelerator specified in a task definition.
type (string) --
The type of resource to assign to a container. The supported values are GPU or InferenceAccelerator .
firelensConfiguration (dict) --
The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide .
type (string) --
The log router to use. The valid values are fluentd or fluentbit .
options (dict) --
The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"} . For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide .
Note
Tasks hosted on Fargate only support the file configuration file type.
(string) --
(string) --
credentialSpecs (list) --
A list of ARNs in SSM or Amazon S3 to a credential spec ( CredSpec ) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions . The maximum number of ARNs is 1.
There are two formats for each ARN.
credentialspecdomainless:MyARN
You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.
Each task that runs on any container instance can join different domains.
You can use this format without joining the container instance to a domain.
credentialspec:MyARN
You use credentialspec:MyARN to provide a CredSpec for a single domain.
You must join the container instance to the domain before you start any tasks that use this task definition.
In both formats, replace MyARN with the ARN in SSM or Amazon S3.
If you provide a credentialspecdomainless:MyARN , the credspec must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.
(string) --
family (string) --
The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.
A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
taskRoleArn (string) --
The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide .
IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code to use the feature. For more information, see Windows IAM roles for tasks in the Amazon Elastic Container Service Developer Guide .
executionRoleArn (string) --
The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide .
networkMode (string) --
The Docker networking mode to use for the containers in the task. The valid values are none , bridge , awsvpc , and host . If no network mode is specified, the default is bridge .
For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none , you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.
With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.
Warning
When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.
If the network mode is awsvpc , the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .
If the network mode is host , you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.
For more information, see Network settings in the Docker run reference .
revision (integer) --
The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is 1 . Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.
volumes (list) --
The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide .
Note
The host and sourcePath parameters aren't supported for tasks run on Fargate.
(dict) --
The data volume configuration for tasks launched using this task definition. Specifying a volume configuration in a task definition is optional. The volume configuration may contain multiple volumes but only one volume configured at launch is supported. Each volume defined in the volume configuration may only specify a name and one of either configuredAtLaunch , dockerVolumeConfiguration , efsVolumeConfiguration , fsxWindowsFileServerVolumeConfiguration , or host . If an empty volume configuration is specified, by default Amazon ECS uses a host volume. For more information, see Using data volumes in tasks.
name (string) --
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.
When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task.
For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition.
When a volume is using the efsVolumeConfiguration , the name is required.
host (dict) --
This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.
Windows containers can mount whole directories on the same drive as $env:ProgramData . Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\ , but not D:\my\path:C:\my\path or D:\:C:\my\path .
sourcePath (string) --
When the host parameter is used, specify a sourcePath to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
If you're using the Fargate launch type, the sourcePath parameter is not supported.
dockerVolumeConfiguration (dict) --
This parameter is specified when you use Docker volumes.
Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.
Note
Docker volumes aren't supported by tasks run on Fargate.
scope (string) --
The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.
autoprovision (boolean) --
If this value is true , the Docker volume is created if it doesn't already exist.
Note
This field is only used if the scope is shared .
driver (string) --
The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. For more information, see Docker plugin discovery. This parameter maps to Driver in the Create a volume section of the Docker Remote API and the xxdriver option to docker volume create.
driverOpts (dict) --
A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the Create a volume section of the Docker Remote API and the xxopt option to docker volume create.
(string) --

(string) --
(string) --
efsVolumeConfiguration (dict) --
This parameter is specified when you use an Amazon Elastic File System file system for task storage.
fileSystemId (string) --
The Amazon EFS file system ID to use.
rootDirectory (string) --
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.
transitEncryption (string) --
Determines whether to use encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be turned on if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide .
transitEncryptionPort (integer) --
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS mount helper in the Amazon Elastic File System User Guide .
authorizationConfig (dict) --
The authorization configuration details for the Amazon EFS file system.
accessPointId (string) --
The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which will enforce the path set on the EFS access point. If an access point is used, transit encryption must be on in the EFSVolumeConfiguration . For more information, see Working with Amazon EFS access points in the Amazon Elastic File System User Guide .
iam (string) --
Determines whether to use the Amazon ECS task role defined in a task definition when mounting the Amazon EFS file system. If it is turned on, transit encryption must be turned on in the EFSVolumeConfiguration . If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS access points in the Amazon Elastic Container Service Developer Guide .
fsxWindowsFileServerVolumeConfiguration (dict) --
This parameter is specified when you use Amazon FSx for Windows File Server file system for task storage.
fileSystemId (string) --

domain (string) --
A fully qualified domain name hosted by an Directory Service Managed Microsoft AD (Active Directory) or self-hosted AD on Amazon EC2.
configuredAtLaunch (boolean) --
Indicates whether the volume should be configured at launch time. This is used to create Amazon EBS volumes for standalone tasks or tasks created as part of a service. Each task definition revision may only have one volume configured at launch in the volume configuration.
To configure a volume at launch time, use this task definition revision and specify a volumeConfigurations object when calling the CreateService , UpdateService , RunTask or StartTask APIs.
status (string) --
The status of the task definition.
requiresAttributes (list) --
The container instance attributes required by your task. When an Amazon EC2 instance is registered to your cluster, the Amazon ECS container agent assigns some standard attributes to the instance. You can apply custom attributes. These are specified as key-value pairs using the Amazon ECS console or the PutAttributes API. These attributes are used when determining task placement for tasks hosted on Amazon EC2 instances. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide .
Note
This parameter isn't supported for tasks run on Fargate.
(dict) --
An attribute is a name-value pair that's associated with an Amazon ECS object. Use attributes to extend the Amazon ECS data model by adding custom metadata to your resources. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide .

deviceType (string) --
The Elastic Inference accelerator type to use.
pidMode (string) --
The process namespace to use for the containers in the task. The valid values are host or task . On Fargate for Linux containers, the only valid value is task . For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.
If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.
If task is specified, all containers within the specified task share the same process namespace.
If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference .
If the host PID mode is used, there's a heightened risk of undesired process namespace exposure. For more information, see Docker security.
Note
This parameter is not supported for Windows containers.
Note
This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
ipcMode (string) --
The IPC resource namespace to use for the containers in the task. The valid values are host , task , or none . If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference .
If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security.
If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide .
For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.

{'volumes': {'configuredAtLaunch': 'boolean'}}
Response {'taskDefinition': {'volumes': {'configuredAtLaunch': 'boolean'}}}
Registers a new task definition from the supplied family and containerDefinitions . Optionally, you can add data volumes to your containers with the volumes parameter. For more information about task definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide .
You can specify a role for your task with the taskRoleArn parameter. When you specify a role for a task, its containers can then use the latest versions of the CLI or SDKs to make API requests to the Amazon Web Services services that are specified in the policy that's associated with the role. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide .
You can specify a Docker networking mode for the containers in your task definition with the networkMode parameter. The available network modes correspond to those described in Network settings in the Docker run reference. If you specify the awsvpc network mode, the task is allocated an elastic network interface, and you must specify a NetworkConfiguration when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .

string
[REQUIRED]
You must specify a family for a task definition. You can use it track multiple versions of the same task definition. The family is used as a name for your task definition. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.
string
The short name or full Amazon Resource Name (ARN) of the IAM role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide .
string
The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide .
string
The Docker networking mode to use for the containers in the task. The valid values are none , bridge , awsvpc , and host . If no network mode is specified, the default is bridge .
For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none , you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.
With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.
Warning
When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.
If the network mode is awsvpc , the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .
If the network mode is host , you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.
For more information, see Network settings in the Docker run reference .
list
[REQUIRED]
A list of container definitions in JSON format that describe the different containers that make up your task.
(dict) --
Container definitions are used in task definitions to describe the different containers that are launched as part of a task.
name (string) --
The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run.
image (string) --
The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.
Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest . For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE .
Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo ).
Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent ).
Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu ).
repositoryCredentials (dict) --
The private repository authentication credentials to use.
credentialsParameter (string) -- [REQUIRED]
The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note
When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu (integer) --
The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run.
This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.
Note
You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.
Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter isn't required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0 , which Windows interprets as 1% of one CPU.
memory (integer) --
The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.
If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
memoryReservation (integer) --
The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run.
If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.
The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
links (list) --
The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge . The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run.
Note
This parameter is not supported for Windows containers.
Warning
Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
(string) --
portMappings (list) --
The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the awsvpc network mode, only specify the containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Port mappings on Windows use the NetNAT gateway address rather than localhost . There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.
This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to none , then you can't specify port mappings. If the network mode of a task definition is set to host , then host ports must either be undefined or they must match the container port in the port mapping.
Note
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
(dict) --
Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.
If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Most fields of this parameter ( containerPort , hostPort , protocol ) maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to host , host ports must either be undefined or match the container port in the port mapping.
Note
You can't expose the same container port for multiple protocols. If you attempt this, an error is returned.
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses.
containerPort (integer) --
The port number on the container that's bound to the user-specified or automatically assigned host port.
If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort .
If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort . Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.
hostPort (integer) --
The port number on the container instance to reserve for your container.
If you specify a containerPortRange , leave this field empty and the value of the hostPort is set as follows:
For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.
If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort .
If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0 ) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.
The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range . If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.
The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.
protocol (string) --
The protocol used for the port mapping. Valid values are tcp and udp . The default is tcp . protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.
name (string) --
The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.
For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
appProtocol (string) --
The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.
If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.
appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
containerPortRange (string) --
The port number range on the container that's bound to the dynamically mapped host port range.
The following rules apply when you specify a containerPortRange :
You must use either the bridge network mode or the awsvpc network mode.
This parameter is available for both the EC2 and Fargate launch types.
This parameter is available for both the Linux and Windows operating systems.
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package
You can specify a maximum of 100 port ranges per container.
You do not specify a hostPortRange . The value of the hostPortRange is set as follows:
For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
The containerPortRange valid values are between 1 and 65535.
A port can only be included in one port mapping per container.
You cannot specify overlapping port ranges.
The first port in the range must be less than last port in the range.
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see Issue #11185 on the Github website. For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide .
You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.
essential (boolean) --
If the essential parameter of a container is marked as true , and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false , its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.
All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide .
entryPoint (list) --
Warning
Early versions of the Amazon ECS container agent don't properly handle entryPoint parameters. If you have problems using entryPoint , update your container agent or enter your commands and arguments as command array items instead.
The entry point that's passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint.
(string) --
command (list) --
The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd. If there are multiple arguments, each argument is a separated string in the array.
(string) --
environment (list) --
The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run.
Warning
We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.
(dict) --
A key-value pair object.
name (string) --
The name of the key-value pair. For environment variables, this is the name of the environment variable.
value (string) --
The value of the key-value pair. For environment variables, this is the value of the environment variable.
environmentFiles (list) --
A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run.
You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file contains an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored. For more information about the environment variable file syntax, see Declare default environment variables in file.
If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide .

If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying environment variables in the Amazon Elastic Container Service Developer Guide .
You must use the following platforms for the Fargate launch type:
Linux platform version 1.4.0 or later.
Windows platform version 1.0.0 or later.
Consider the following when using the Fargate launch type:
The file is handled like a native Docker env-file.
There is no support for shell escape handling.
The container entry point interperts the VARIABLE values.
value (string) -- [REQUIRED]
The Amazon Resource Name (ARN) of the Amazon S3 object containing the environment variable file.
type (string) -- [REQUIRED]
The file type to use. The only supported value is s3 .
mountPoints (list) --
The mount points for data volumes in your container.
This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run.
Windows containers can mount whole directories on the same drive as $env:ProgramData . Windows containers can't mount directories on a different drive, and mount point can't be across drives.
(dict) --
The details for a volume mount point that's used in a container definition.
sourceVolume (string) --
The name of the volume to mount. Must be a volume name referenced in the name parameter of task definition volume .

For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
(dict) --
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
Your Amazon ECS container instances require at least version 1.26.0 of the container agent to use container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .

For tasks that use the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
containerName (string) -- [REQUIRED]
The name of a container.
condition (string) -- [REQUIRED]
The dependency condition of the container. The following are the available conditions and their behavior:
START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.
COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.
SUCCESS - This condition is the same as COMPLETE , but it also requires that the container exits with a zero status. This condition can't be set on an essential container.
HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.
startTimeout (integer) --
Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE , SUCCESS , or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state.
Note
When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value.
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
The valid values are 2-120 seconds.
stopTimeout (integer) --
Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
The valid values are 2-120 seconds.

(string) --
(string) --
ulimits (list) --
A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it overrides the default values set by Docker. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type.
Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 4096 .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
This parameter is not supported for Windows containers.
(dict) --

The hard limit for the ulimit type.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
logDriver (string) -- [REQUIRED]

For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

(string) --
secretOptions (list) --
The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.
To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.
For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
name (string) -- [REQUIRED]
The name of the secret.
valueFrom (string) -- [REQUIRED]
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide .
Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
healthCheck (dict) --
The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run.
command (list) -- [REQUIRED]
A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to run the command arguments directly, or CMD-SHELL to run the command with the container's default shell.
When you use the Amazon Web Services Management Console JSON panel, the Command Line Interface, or the APIs, enclose the list of commands in double quotes and brackets.
[ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]
You don't include the double quotes and brackets when you use the Amazon Web Services Management Console.
CMD-SHELL, curl -f http://localhost/ || exit 1
An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in the Create a container section of the Docker Remote API.
(string) --
interval (integer) --
The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.

The optional grace period to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You can specify between 0 and 300 seconds. By default, the startPeriod is off.
Note
If a health check succeeds within the startPeriod , then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
systemControls (list) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.
Note
We don't recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. For tasks that use the awsvpc network mode, the container that's started last determines which systemControls parameters take effect. For tasks that use the host network mode, it changes the container instance's namespaced kernel parameters as well as the containers.
Note
This parameter is not supported for Windows containers.
Note
This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
(dict) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run.
We don't recommend that you specify network-related systemControls parameters for multiple containers in a single task. This task also uses either the awsvpc or host network mode. It does it for the following reasons.
For tasks that use the awsvpc network mode, if you set systemControls for any container, it applies to all containers in the task. If you set different systemControls for multiple containers in a single task, the container that's started last determines which systemControls take effect.
For tasks that use the host network mode, the systemControls parameter applies to the container instance's kernel parameter and that of all containers of any tasks running on that container instance.
namespace (string) --
The namespaced kernel parameter to set a value for.
value (string) --
The namespaced kernel parameter to set a value for.
Valid IPC namespace values: "kernel.msgmax" | "kernel.msgmnb" | "kernel.msgmni" | "kernel.sem" | "kernel.shmall" | "kernel.shmmax" | "kernel.shmmni" | "kernel.shm_rmid_forced" , and Sysctls that start with "fs.mqueue.*"
Valid network namespace values: Sysctls that start with "net.*"
All of these values are supported by Fargate.
resourceRequirements (list) --
The type and amount of a resource to assign to a container. The only supported resource is a GPU.
(dict) --
The type and amount of a resource to assign to a container. The supported resource types are GPUs and Elastic Inference accelerators. For more information, see Working with GPUs on Amazon ECS or Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide
value (string) -- [REQUIRED]
The value for the specified resource type.
If the GPU type is used, the value is the number of physical GPUs the Amazon ECS container agent reserves for the container. The number of GPUs that's reserved for all containers in a task can't exceed the number of available GPUs on the container instance that the task is launched on.
If the InferenceAccelerator type is used, the value matches the deviceName for an InferenceAccelerator specified in a task definition.
type (string) -- [REQUIRED]
The type of resource to assign to a container. The supported values are GPU or InferenceAccelerator .
firelensConfiguration (dict) --
The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide .
type (string) -- [REQUIRED]
The log router to use. The valid values are fluentd or fluentbit .
options (dict) --
The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"} . For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide .
Note
Tasks hosted on Fargate only support the file configuration file type.
(string) --
(string) --
credentialSpecs (list) --
A list of ARNs in SSM or Amazon S3 to a credential spec ( CredSpec ) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions . The maximum number of ARNs is 1.
There are two formats for each ARN.
credentialspecdomainless:MyARN
You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.
Each task that runs on any container instance can join different domains.
You can use this format without joining the container instance to a domain.
credentialspec:MyARN
You use credentialspec:MyARN to provide a CredSpec for a single domain.
You must join the container instance to the domain before you start any tasks that use this task definition.
In both formats, replace MyARN with the ARN in SSM or Amazon S3.
If you provide a credentialspecdomainless:MyARN , the credspec must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.
(string) --
list
A list of volume definitions in JSON format that containers in your task might use.
(dict) --
The data volume configuration for tasks launched using this task definition. Specifying a volume configuration in a task definition is optional. The volume configuration may contain multiple volumes but only one volume configured at launch is supported. Each volume defined in the volume configuration may only specify a name and one of either configuredAtLaunch , dockerVolumeConfiguration , efsVolumeConfiguration , fsxWindowsFileServerVolumeConfiguration , or host . If an empty volume configuration is specified, by default Amazon ECS uses a host volume. For more information, see Using data volumes in tasks.
name (string) --
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.
When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task.
For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition.
When a volume is using the efsVolumeConfiguration , the name is required.
host (dict) --
This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.
Windows containers can mount whole directories on the same drive as $env:ProgramData . Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\ , but not D:\my\path:C:\my\path or D:\:C:\my\path .
sourcePath (string) --
When the host parameter is used, specify a sourcePath to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
If you're using the Fargate launch type, the sourcePath parameter is not supported.
dockerVolumeConfiguration (dict) --
This parameter is specified when you use Docker volumes.
Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.
Note
Docker volumes aren't supported by tasks run on Fargate.
scope (string) --
The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.
autoprovision (boolean) --
If this value is true , the Docker volume is created if it doesn't already exist.
Note
This field is only used if the scope is shared .
driver (string) --
The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. For more information, see Docker plugin discovery. This parameter maps to Driver in the Create a volume section of the Docker Remote API and the xxdriver option to docker volume create.
driverOpts (dict) --
A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the Create a volume section of the Docker Remote API and the xxopt option to docker volume create.
(string) --
(string) --
labels (dict) --
Custom metadata to add to your Docker volume. This parameter maps to Labels in the Create a volume section of the Docker Remote API and the xxlabel option to docker volume create.
(string) --
(string) --
efsVolumeConfiguration (dict) --
This parameter is specified when you use an Amazon Elastic File System file system for task storage.
fileSystemId (string) -- [REQUIRED]
The Amazon EFS file system ID to use.
rootDirectory (string) --
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.
transitEncryption (string) --
Determines whether to use encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be turned on if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide .
transitEncryptionPort (integer) --
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS mount helper in the Amazon Elastic File System User Guide .
authorizationConfig (dict) --
The authorization configuration details for the Amazon EFS file system.
accessPointId (string) --
The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which will enforce the path set on the EFS access point. If an access point is used, transit encryption must be on in the EFSVolumeConfiguration . For more information, see Working with Amazon EFS access points in the Amazon Elastic File System User Guide .
iam (string) --
Determines whether to use the Amazon ECS task role defined in a task definition when mounting the Amazon EFS file system. If it is turned on, transit encryption must be turned on in the EFSVolumeConfiguration . If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS access points in the Amazon Elastic Container Service Developer Guide .
fsxWindowsFileServerVolumeConfiguration (dict) --
This parameter is specified when you use Amazon FSx for Windows File Server file system for task storage.
fileSystemId (string) -- [REQUIRED]
The Amazon FSx for Windows File Server file system ID to use.
rootDirectory (string) -- [REQUIRED]
The directory within the Amazon FSx for Windows File Server file system to mount as the root directory inside the host.
authorizationConfig (dict) -- [REQUIRED]
The authorization configuration details for the Amazon FSx for Windows File Server file system.
credentialsParameter (string) -- [REQUIRED]
The authorization credential option to use. The authorization credential options can be provided using either the Amazon Resource Name (ARN) of an Secrets Manager secret or SSM Parameter Store parameter. The ARN refers to the stored credentials.
domain (string) -- [REQUIRED]
A fully qualified domain name hosted by an Directory Service Managed Microsoft AD (Active Directory) or self-hosted AD on Amazon EC2.
configuredAtLaunch (boolean) --
Indicates whether the volume should be configured at launch time. This is used to create Amazon EBS volumes for standalone tasks or tasks created as part of a service. Each task definition revision may only have one volume configured at launch in the volume configuration.
To configure a volume at launch time, use this task definition revision and specify a volumeConfigurations object when calling the CreateService , UpdateService , RunTask or StartTask APIs.
list
An array of placement constraint objects to use for the task. You can specify a maximum of 10 constraints for each task. This limit includes constraints in the task definition and those specified at runtime.
(dict) --
The constraint on task placement in the task definition. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide .
Note
Task placement constraints aren't supported for tasks run on Fargate.
type (string) --
The type of constraint. The MemberOf constraint restricts selection to be from a group of valid candidates.
expression (string) --
A cluster query language expression to apply to the constraint. For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .
list
The task launch type that Amazon ECS validates the task definition against. A client exception is returned if the task definition doesn't validate against the compatibilities specified. If no value is specified, the parameter is omitted from the response.
(string) --
string
The number of CPU units used by the task. It can be expressed as an integer using CPU units (for example, 1024 ) or as a string using vCPUs (for example, 1 vCPU or 1 vcpu ) in a task definition. String values are converted to an integer indicating the CPU units when the task definition is registered.
Note
Task-level CPU and memory parameters are ignored for Windows containers. We recommend specifying container-level resources for Windows containers.
If you're using the EC2 launch type, this field is optional. Supported values are between 128 CPU units ( 0.125 vCPUs) and 10240 CPU units ( 10 vCPUs). If you do not specify a value, the parameter is ignored.
If you're using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of supported values for the memory parameter:
The CPU units cannot be less than 1 vCPU when you use Windows containers on Fargate.
256 (.25 vCPU) - Available memory values: 512 (0.5 GB), 1024 (1 GB), 2048 (2 GB)

list
The metadata that you apply to the task definition to help you categorize and organize them. Each tag consists of a key and an optional value. You define both of them.
The following basic restrictions apply to tags:
Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
string
The process namespace to use for the containers in the task. The valid values are host or task . On Fargate for Linux containers, the only valid value is task . For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.
If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.
If task is specified, all containers within the specified task share the same process namespace.
If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference .
If the host PID mode is used, there's a heightened risk of undesired process namespace exposure. For more information, see Docker security.
Note
This parameter is not supported for Windows containers.
Note
This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
string
The IPC resource namespace to use for the containers in the task. The valid values are host , task , or none . If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference .
If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security.
If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide .
For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.
For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task.
Note
This parameter is not supported for Windows containers or tasks run on Fargate.
dict
The configuration details for the App Mesh proxy.
For tasks hosted on Amazon EC2 instances, the container instances require at least version 1.26.0 of the container agent and at least version 1.26.0-1 of the ecs-init package to use a proxy configuration. If your container instances are launched from the Amazon ECS-optimized AMI version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized AMI versions in the Amazon Elastic Container Service Developer Guide .

IgnoredGID - (Required) The group ID (GID) of the proxy container as defined by the user parameter in a container definition. This is used to ensure the proxy ignores its own traffic. If IgnoredUID is specified, this field can be empty.
AppPorts - (Required) The list of ports that the application uses. Network traffic to these ports is forwarded to the ProxyIngressPort and ProxyEgressPort .
ProxyIngressPort - (Required) Specifies the port that incoming traffic to the AppPorts is directed to.
ProxyEgressPort - (Required) Specifies the port that outgoing traffic from the AppPorts is directed to.
EgressIgnoredPorts - (Required) The egress traffic going to the specified ports is ignored and not redirected to the ProxyEgressPort . It can be an empty list.
EgressIgnoredIPs - (Required) The egress traffic going to the specified IP addresses is ignored and not redirected to the ProxyEgressPort . It can be an empty list.

Response Structure
(dict) --
taskDefinition (dict) --
The full description of the registered task definition.
taskDefinitionArn (string) --
The full Amazon Resource Name (ARN) of the task definition.
containerDefinitions (list) --
A list of container definitions in JSON format that describe the different containers that make up your task. For more information about container definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon Elastic Container Service Developer Guide .
(dict) --
Container definitions are used in task definitions to describe the different containers that are launched as part of a task.
name (string) --
The name of a container. If you're linking multiple containers together in a task definition, the name of one container can be entered in the links of another container to connect the containers. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. This parameter maps to name in the Create a container section of the Docker Remote API and the --name option to docker run.
image (string) --
The image used to start a container. This string is passed directly to the Docker daemon. By default, images in the Docker Hub registry are available. Other repositories are specified with either repository-url/image:tag or repository-url/image@digest . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.
When a new task starts, the Amazon ECS container agent pulls the latest version of the specified image and tag for the container to use. However, subsequent updates to a repository image aren't propagated to already running tasks.
Images in Amazon ECR repositories can be specified by either using the full registry/repository:tag or registry/repository@digest . For example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>:latest or 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name>@sha256:94afd1f2e64d908bc90dbca0035a5b567EXAMPLE .
Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo ).
Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent ).
Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu ).
repositoryCredentials (dict) --
The private repository authentication credentials to use.
credentialsParameter (string) --
The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
Note
When you use the Amazon ECS API, CLI, or Amazon Web Services SDK, if the secret exists in the same Region as the task that you're launching then you can use either the full ARN or the name of the secret. When you use the Amazon Web Services Management Console, you must specify the full ARN of the secret.
cpu (integer) --
The number of cpu units reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run.
This field is optional for tasks using the Fargate launch type, and the only requirement is that the total amount of CPU reserved for all containers within a task be lower than the task-level cpu value.
Note
You can determine the number of CPU units that are available per EC2 instance type by multiplying the vCPUs listed for that instance type on the Amazon EC2 Instances detail page by 1,024.
Linux containers share unallocated CPU units with other containers on the container instance with the same ratio as their allocated amount. For example, if you run a single-container task on a single-core instance type with 512 CPU units specified for that container, and that's the only task running on the container instance, that container could use the full 1,024 CPU unit share at any given time. However, if you launched another copy of the same task on that container instance, each task is guaranteed a minimum of 512 CPU units when needed. Moreover, each container could float to higher CPU usage if the other container was not using it. If both tasks were 100% active all of the time, they would be limited to 512 CPU units.
On Linux container instances, the Docker daemon on the container instance uses the CPU value to calculate the relative CPU share ratios for running containers. For more information, see CPU share constraint in the Docker documentation. The minimum valid CPU share value that the Linux kernel allows is 2. However, the CPU parameter isn't required, and you can use CPU values below 2 in your container definitions. For CPU values below 2 (including null), the behavior varies based on your Amazon ECS container agent version:
Agent versions less than or equal to 1.1.0: Null and zero CPU values are passed to Docker as 0, which Docker then converts to 1,024 CPU shares. CPU values of 1 are passed to Docker as 1, which the Linux kernel converts to two CPU shares.
Agent versions greater than or equal to 1.2.0: Null, zero, and CPU values of 1 are passed to Docker as 2.
On Windows container instances, the CPU limit is enforced as an absolute limit, or a quota. Windows containers only have access to the specified amount of CPU that's described in the task definition. A null or zero CPU value is passed to Docker as 0 , which Windows interprets as 1% of one CPU.
memory (integer) --
The amount (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. The total amount of memory reserved for all containers within a task must be lower than the task memory value, if one is specified. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.
If using the Fargate launch type, this parameter is optional.
If using the EC2 launch type, you must specify either a task-level memory value or a container-level memory value. If you specify both a container-level memory and memoryReservation value, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
memoryReservation (integer) --
The soft limit (in MiB) of memory to reserve for the container. When system memory is under heavy contention, Docker attempts to keep the container memory to this soft limit. However, your container can consume more memory when it needs to, up to either the hard limit specified with the memory parameter (if applicable), or all of the available memory on the container instance, whichever comes first. This parameter maps to MemoryReservation in the Create a container section of the Docker Remote API and the --memory-reservation option to docker run.
If a task-level memory value is not specified, you must specify a non-zero integer for one or both of memory or memoryReservation in a container definition. If you specify both, memory must be greater than memoryReservation . If you specify memoryReservation , then that value is subtracted from the available memory resources for the container instance where the container is placed. Otherwise, the value of memory is used.
For example, if your container normally uses 128 MiB of memory, but occasionally bursts to 256 MiB of memory for short periods of time, you can set a memoryReservation of 128 MiB, and a memory hard limit of 300 MiB. This configuration would allow the container to only reserve 128 MiB of memory from the remaining resources on the container instance, but also allow the container to consume more memory resources when needed.
The Docker 20.10.0 or later daemon reserves a minimum of 6 MiB of memory for a container. So, don't specify less than 6 MiB of memory for your containers.
The Docker 19.03.13-ce or earlier daemon reserves a minimum of 4 MiB of memory for a container. So, don't specify less than 4 MiB of memory for your containers.
links (list) --
The links parameter allows containers to communicate with each other without the need for port mappings. This parameter is only supported if the network mode of a task definition is bridge . The name:internalName construct is analogous to name:alias in Docker links. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. For more information about linking Docker containers, go to Legacy container links in the Docker documentation. This parameter maps to Links in the Create a container section of the Docker Remote API and the --link option to docker run.
Note
This parameter is not supported for Windows containers.
Warning
Containers that are collocated on a single container instance may be able to communicate with each other without requiring links or host port mappings. Network isolation is achieved on the container instance using security groups and VPC settings.
(string) --
portMappings (list) --
The list of port mappings for the container. Port mappings allow containers to access ports on the host container instance to send or receive traffic.
For task definitions that use the awsvpc network mode, only specify the containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Port mappings on Windows use the NetNAT gateway address rather than localhost . There's no loopback for port mappings on Windows, so you can't access a container's mapped port from the host itself.
This parameter maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to none , then you can't specify port mappings. If the network mode of a task definition is set to host , then host ports must either be undefined or they must match the container port in the port mapping.
Note
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the Network Bindings section of a container description for a selected task in the Amazon ECS console. The assignments are also visible in the networkBindings section DescribeTasks responses.
(dict) --
Port mappings allow containers to access ports on the host container instance to send or receive traffic. Port mappings are specified as part of the container definition.
If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort . The hostPort can be left blank or it must be the same value as the containerPort .
Most fields of this parameter ( containerPort , hostPort , protocol ) maps to PortBindings in the Create a container section of the Docker Remote API and the --publish option to docker run. If the network mode of a task definition is set to host , host ports must either be undefined or match the container port in the port mapping.
Note
You can't expose the same container port for multiple protocols. If you attempt this, an error is returned.
After a task reaches the RUNNING status, manual and automatic host and container port assignments are visible in the networkBindings section of DescribeTasks API responses.
containerPort (integer) --
The port number on the container that's bound to the user-specified or automatically assigned host port.
If you use containers in a task with the awsvpc or host network mode, specify the exposed ports using containerPort .
If you use containers in a task with the bridge network mode and you specify a container port and not a host port, your container automatically receives a host port in the ephemeral port range. For more information, see hostPort . Port mappings that are automatically assigned in this way do not count toward the 100 reserved ports limit of a container instance.
hostPort (integer) --
The port number on the container instance to reserve for your container.
If you specify a containerPortRange , leave this field empty and the value of the hostPort is set as follows:
For containers in a task with the awsvpc network mode, the hostPort is set to the same value as the containerPort . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open ports on the host and automatically binds them to the container ports. This is a dynamic mapping strategy.
If you use containers in a task with the awsvpc or host network mode, the hostPort can either be left blank or set to the same value as the containerPort .
If you use containers in a task with the bridge network mode, you can specify a non-reserved host port for your container port mapping, or you can omit the hostPort (or set it to 0 ) while specifying a containerPort and your container automatically receives a port in the ephemeral port range for your container instance operating system and Docker version.
The default ephemeral port range for Docker version 1.6.0 and later is listed on the instance under /proc/sys/net/ipv4/ip_local_port_range . If this kernel parameter is unavailable, the default ephemeral port range from 49153 through 65535 (Linux) or 49152 through 65535 (Windows) is used. Do not attempt to specify a host port in the ephemeral port range as these are reserved for automatic assignment. In general, ports below 32768 are outside of the ephemeral port range.
The default reserved ports are 22 for SSH, the Docker ports 2375 and 2376, and the Amazon ECS container agent ports 51678-51680. Any host port that was previously specified in a running task is also reserved while the task is running. That is, after a task stops, the host port is released. The current reserved ports are displayed in the remainingResources of DescribeContainerInstances output. A container instance can have up to 100 reserved ports at a time. This number includes the default reserved ports. Automatically assigned ports aren't included in the 100 reserved ports quota.
protocol (string) --
The protocol used for the port mapping. Valid values are tcp and udp . The default is tcp . protocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.
name (string) --
The name that's used for the port mapping. This parameter only applies to Service Connect. This parameter is the name that you use in the serviceConnectConfiguration of a service. The name can include up to 64 characters. The characters can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.
For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
appProtocol (string) --
The application protocol that's used for the port mapping. This parameter only applies to Service Connect. We recommend that you set this parameter to be consistent with the protocol that your application uses. If you set this parameter, Amazon ECS adds protocol-specific connection handling to the Service Connect proxy. If you set this parameter, Amazon ECS adds protocol-specific telemetry in the Amazon ECS console and CloudWatch.
If you don't set a value for this parameter, then TCP is used. However, Amazon ECS doesn't add protocol-specific telemetry for TCP.
appProtocol is immutable in a Service Connect service. Updating this field requires a service deletion and redeployment.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
containerPortRange (string) --
The port number range on the container that's bound to the dynamically mapped host port range.
The following rules apply when you specify a containerPortRange :
You must use either the bridge network mode or the awsvpc network mode.
This parameter is available for both the EC2 and Fargate launch types.
This parameter is available for both the Linux and Windows operating systems.
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package
You can specify a maximum of 100 port ranges per container.
You do not specify a hostPortRange . The value of the hostPortRange is set as follows:
For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
The containerPortRange valid values are between 1 and 65535.
A port can only be included in one port mapping per container.
You cannot specify overlapping port ranges.
The first port in the range must be less than last port in the range.
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see Issue #11185 on the Github website. For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide .
You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.
essential (boolean) --
If the essential parameter of a container is marked as true , and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false , its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.
All tasks must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide .
entryPoint (list) --
Warning
Early versions of the Amazon ECS container agent don't properly handle entryPoint parameters. If you have problems using entryPoint , update your container agent or enter your commands and arguments as command array items instead.
The entry point that's passed to the container. This parameter maps to Entrypoint in the Create a container section of the Docker Remote API and the --entrypoint option to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#entrypoint.

environment (list) --
The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run.
Warning
We don't recommend that you use plaintext environment variables for sensitive information, such as credential data.
(dict) --
A key-value pair object.
name (string) --
The name of the key-value pair. For environment variables, this is the name of the environment variable.

environmentFiles (list) --
A list of files containing the environment variables to pass to a container. This parameter maps to the --env-file option to docker run.
You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file contains an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored. For more information about the environment variable file syntax, see Declare default environment variables in file.
If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying Environment Variables in the Amazon Elastic Container Service Developer Guide .

(string) --
devices (list) --
Any host devices to expose to the container. This parameter maps to Devices in the Create a container section of the Docker Remote API and the --device option to docker run.
Note
If you're using tasks that use the Fargate launch type, the devices parameter isn't supported.

(string) --
maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter will be translated to the --memory-swap option to docker run where the value would be the sum of the container memory plus the maxSwap value.
If a maxSwap value of 0 is specified, the container will not use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container will use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
If you're using tasks that use the Fargate launch type, the maxSwap parameter isn't supported.
If you're using tasks on Amazon Linux 2023 the swappiness parameter isn't supported.
swappiness (integer) --
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 will cause swapping to not happen unless absolutely necessary. A swappiness value of 100 will cause pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter is not specified, a default value of 60 is used. If a value is not specified for maxSwap then this parameter is ignored. This parameter maps to the --memory-swappiness option to docker run.

To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.
To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.
For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
name (string) --
The name of the secret.
valueFrom (string) --
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide .
Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
dependsOn (list) --
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies on other containers in a task definition. When a dependency is defined for container startup, for container shutdown it is reversed.
For tasks using the EC2 launch type, the container instances require at least version 1.26.0 of the container agent to turn on container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
(dict) --
The dependencies defined for container startup and shutdown. A container can contain multiple dependencies. When a dependency is defined for container startup, for container shutdown it is reversed.
Your Amazon ECS container instances require at least version 1.26.0 of the container agent to use container dependencies. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
Note
For tasks that use the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
containerName (string) --
The name of a container.
condition (string) --
The dependency condition of the container. The following are the available conditions and their behavior:
START - This condition emulates the behavior of links and volumes today. It validates that a dependent container is started before permitting other containers to start.
COMPLETE - This condition validates that a dependent container runs to completion (exits) before permitting other containers to start. This can be useful for nonessential containers that run a script and then exit. This condition can't be set on an essential container.
SUCCESS - This condition is the same as COMPLETE , but it also requires that the container exits with a zero status. This condition can't be set on an essential container.
HEALTHY - This condition validates that the dependent container passes its Docker health check before permitting other containers to start. This requires that the dependent container has health checks configured. This condition is confirmed only at task startup.
startTimeout (integer) --
Time duration (in seconds) to wait before giving up on resolving dependencies for a container. For example, you specify two containers in a task definition with containerA having a dependency on containerB reaching a COMPLETE , SUCCESS , or HEALTHY status. If a startTimeout value is specified for containerB and it doesn't reach the desired status within that time then containerA gives up and not start. This results in the task transitioning to a STOPPED state.
Note
When the ECS_CONTAINER_START_TIMEOUT container agent configuration variable is used, it's enforced independently from this start timeout value.
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
For tasks using the EC2 launch type, your container instances require at least version 1.26.0 of the container agent to use a container start timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
The valid values are 2-120 seconds.
stopTimeout (integer) --
Time duration (in seconds) to wait before the container is forcefully killed if it doesn't exit normally on its own.
For tasks using the Fargate launch type, the task or service requires the following platforms:
Linux platform version 1.3.0 or later.
Windows platform version 1.0.0 or later.
The max stop timeout value is 120 seconds and if the parameter is not specified, the default value of 30 seconds is used.
For tasks that use the EC2 launch type, if the stopTimeout parameter isn't specified, the value set for the Amazon ECS container agent configuration variable ECS_CONTAINER_STOP_TIMEOUT is used. If neither the stopTimeout parameter or the ECS_CONTAINER_STOP_TIMEOUT agent configuration variable are set, then the default values of 30 seconds for Linux containers and 30 seconds on Windows containers are used. Your container instances require at least version 1.26.0 of the container agent to use a container stop timeout value. However, we recommend using the latest container agent version. For information about checking your agent version and updating to the latest version, see Updating the Amazon ECS Container Agent in the Amazon Elastic Container Service Developer Guide . If you're using an Amazon ECS-optimized Linux AMI, your instance needs at least version 1.26.0-1 of the ecs-init package. If your container instances are launched from version 20190301 or later, then they contain the required versions of the container agent and ecs-init . For more information, see Amazon ECS-optimized Linux AMI in the Amazon Elastic Container Service Developer Guide .
The valid values are 2-120 seconds.

(string) --
(string) --
ulimits (list) --
A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it overrides the default values set by Docker. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run. Valid naming values are displayed in the Ulimit data type.
Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 4096 .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
This parameter is not supported for Windows containers.
(dict) --
The ulimit settings to pass to the container.
Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 4096 .
You can specify the ulimit settings for a container in a task definition.
name (string) --
The type of the ulimit .
softLimit (integer) --
The soft limit for the ulimit type.
hardLimit (integer) --
The hard limit for the ulimit type.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
logDriver (string) --
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
(string) --
(string) --
secretOptions (list) --
The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.
To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.
For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
name (string) --
The name of the secret.
valueFrom (string) --
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide .
Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
healthCheck (dict) --
The container health check command and associated configuration parameters for the container. This parameter maps to HealthCheck in the Create a container section of the Docker Remote API and the HEALTHCHECK parameter of docker run.
command (list) --
A string array representing the command that the container runs to determine if it is healthy. The string array must start with CMD to run the command arguments directly, or CMD-SHELL to run the command with the container's default shell.
When you use the Amazon Web Services Management Console JSON panel, the Command Line Interface, or the APIs, enclose the list of commands in double quotes and brackets.
[ "CMD-SHELL", "curl -f http://localhost/ || exit 1" ]
You don't include the double quotes and brackets when you use the Amazon Web Services Management Console.
CMD-SHELL, curl -f http://localhost/ || exit 1
An exit code of 0 indicates success, and non-zero exit code indicates failure. For more information, see HealthCheck in the Create a container section of the Docker Remote API.
(string) --
interval (integer) --
The time period in seconds between each health check execution. You may specify between 5 and 300 seconds. The default value is 30 seconds.
timeout (integer) --
The time period in seconds to wait for a health check to succeed before it is considered a failure. You may specify between 2 and 60 seconds. The default value is 5.
retries (integer) --
The number of times to retry a failed health check before the container is considered unhealthy. You may specify between 1 and 10 retries. The default value is 3.
startPeriod (integer) --
The optional grace period to provide containers time to bootstrap before failed health checks count towards the maximum number of retries. You can specify between 0 and 300 seconds. By default, the startPeriod is off.
Note
If a health check succeeds within the startPeriod , then the container is considered healthy and any subsequent failures count toward the maximum number of retries.
systemControls (list) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run. For example, you can configure net.ipv4.tcp_keepalive_time setting to maintain longer lived connections.
Note
We don't recommended that you specify network-related systemControls parameters for multiple containers in a single task that also uses either the awsvpc or host network modes. For tasks that use the awsvpc network mode, the container that's started last determines which systemControls parameters take effect. For tasks that use the host network mode, it changes the container instance's namespaced kernel parameters as well as the containers.
Note
This parameter is not supported for Windows containers.
Note
This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
(dict) --
A list of namespaced kernel parameters to set in the container. This parameter maps to Sysctls in the Create a container section of the Docker Remote API and the --sysctl option to docker run.
We don't recommend that you specify network-related systemControls parameters for multiple containers in a single task. This task also uses either the awsvpc or host network mode. It does it for the following reasons.
For tasks that use the awsvpc network mode, if you set systemControls for any container, it applies to all containers in the task. If you set different systemControls for multiple containers in a single task, the container that's started last determines which systemControls take effect.
For tasks that use the host network mode, the systemControls parameter applies to the container instance's kernel parameter and that of all containers of any tasks running on that container instance.
namespace (string) --
The namespaced kernel parameter to set a value for.
value (string) --
The namespaced kernel parameter to set a value for.
Valid IPC namespace values: "kernel.msgmax" | "kernel.msgmnb" | "kernel.msgmni" | "kernel.sem" | "kernel.shmall" | "kernel.shmmax" | "kernel.shmmni" | "kernel.shm_rmid_forced" , and Sysctls that start with "fs.mqueue.*"
Valid network namespace values: Sysctls that start with "net.*"
All of these values are supported by Fargate.
resourceRequirements (list) --
The type and amount of a resource to assign to a container. The only supported resource is a GPU.
(dict) --
The type and amount of a resource to assign to a container. The supported resource types are GPUs and Elastic Inference accelerators. For more information, see Working with GPUs on Amazon ECS or Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide
value (string) --
The value for the specified resource type.
If the GPU type is used, the value is the number of physical GPUs the Amazon ECS container agent reserves for the container. The number of GPUs that's reserved for all containers in a task can't exceed the number of available GPUs on the container instance that the task is launched on.
If the InferenceAccelerator type is used, the value matches the deviceName for an InferenceAccelerator specified in a task definition.
type (string) --
The type of resource to assign to a container. The supported values are GPU or InferenceAccelerator .
firelensConfiguration (dict) --
The FireLens configuration for the container. This is used to specify and configure a log router for container logs. For more information, see Custom Log Routing in the Amazon Elastic Container Service Developer Guide .
type (string) --
The log router to use. The valid values are fluentd or fluentbit .
options (dict) --
The options to use when configuring the log router. This field is optional and can be used to specify a custom configuration file or to add additional metadata, such as the task, task definition, cluster, and container instance details to the log event. If specified, the syntax to use is "options":{"enable-ecs-log-metadata":"true|false","config-file-type:"s3|file","config-file-value":"arn:aws:s3:::mybucket/fluent.conf|filepath"} . For more information, see Creating a task definition that uses a FireLens configuration in the Amazon Elastic Container Service Developer Guide .
Note
Tasks hosted on Fargate only support the file configuration file type.
(string) --
(string) --
credentialSpecs (list) --
A list of ARNs in SSM or Amazon S3 to a credential spec ( CredSpec ) file that configures the container for Active Directory authentication. We recommend that you use this parameter instead of the dockerSecurityOptions . The maximum number of ARNs is 1.
There are two formats for each ARN.
credentialspecdomainless:MyARN
You use credentialspecdomainless:MyARN to provide a CredSpec with an additional section for a secret in Secrets Manager. You provide the login credentials to the domain in the secret.
Each task that runs on any container instance can join different domains.
You can use this format without joining the container instance to a domain.
credentialspec:MyARN
You use credentialspec:MyARN to provide a CredSpec for a single domain.
You must join the container instance to the domain before you start any tasks that use this task definition.
In both formats, replace MyARN with the ARN in SSM or Amazon S3.
If you provide a credentialspecdomainless:MyARN , the credspec must provide a ARN in Secrets Manager for a secret containing the username, password, and the domain to connect to. For better security, the instance isn't joined to the domain for domainless authentication. Other applications on the instance can't use the domainless credentials. You can use this parameter to run tasks on the same instance, even it the tasks need to join different domains. For more information, see Using gMSAs for Windows Containers and Using gMSAs for Linux Containers.
(string) --
family (string) --
The name of a family that this task definition is registered to. Up to 255 characters are allowed. Letters (both uppercase and lowercase letters), numbers, hyphens (-), and underscores (_) are allowed.
A family groups multiple versions of a task definition. Amazon ECS gives the first task definition that you registered to a family a revision number of 1. Amazon ECS gives sequential revision numbers to each task definition that you add.
taskRoleArn (string) --
The short name or full Amazon Resource Name (ARN) of the Identity and Access Management role that grants containers in the task permission to call Amazon Web Services APIs on your behalf. For more information, see Amazon ECS Task Role in the Amazon Elastic Container Service Developer Guide .
IAM roles for tasks on Windows require that the -EnableTaskIAMRole option is set when you launch the Amazon ECS-optimized Windows AMI. Your containers must also run some configuration code to use the feature. For more information, see Windows IAM roles for tasks in the Amazon Elastic Container Service Developer Guide .
executionRoleArn (string) --
The Amazon Resource Name (ARN) of the task execution role that grants the Amazon ECS container agent permission to make Amazon Web Services API calls on your behalf. The task execution IAM role is required depending on the requirements of your task. For more information, see Amazon ECS task execution IAM role in the Amazon Elastic Container Service Developer Guide .
networkMode (string) --
The Docker networking mode to use for the containers in the task. The valid values are none , bridge , awsvpc , and host . If no network mode is specified, the default is bridge .
For Amazon ECS tasks on Fargate, the awsvpc network mode is required. For Amazon ECS tasks on Amazon EC2 Linux instances, any network mode can be used. For Amazon ECS tasks on Amazon EC2 Windows instances, <default> or awsvpc can be used. If the network mode is set to none , you cannot specify port mappings in your container definitions, and the tasks containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.
With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.
Warning
When using the host network mode, you should not run containers using the root user (UID 0). It is considered best practice to use a non-root user.
If the network mode is awsvpc , the task is allocated an elastic network interface, and you must specify a NetworkConfiguration value when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide .
If the network mode is host , you cannot run multiple instantiations of the same task on a single container instance when port mappings are used.
For more information, see Network settings in the Docker run reference .
revision (integer) --
The revision of the task in a particular family. The revision is a version number of a task definition in a family. When you register a task definition for the first time, the revision is 1 . Each time that you register a new revision of a task definition in the same family, the revision value always increases by one. This is even if you deregistered previous revisions in this family.
volumes (list) --
The list of data volume definitions for the task. For more information, see Using data volumes in tasks in the Amazon Elastic Container Service Developer Guide .
Note
The host and sourcePath parameters aren't supported for tasks run on Fargate.
(dict) --
The data volume configuration for tasks launched using this task definition. Specifying a volume configuration in a task definition is optional. The volume configuration may contain multiple volumes but only one volume configured at launch is supported. Each volume defined in the volume configuration may only specify a name and one of either configuredAtLaunch , dockerVolumeConfiguration , efsVolumeConfiguration , fsxWindowsFileServerVolumeConfiguration , or host . If an empty volume configuration is specified, by default Amazon ECS uses a host volume. For more information, see Using data volumes in tasks.
name (string) --
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.
When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task.
For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition.
When a volume is using the efsVolumeConfiguration , the name is required.
host (dict) --
This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.
Windows containers can mount whole directories on the same drive as $env:ProgramData . Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\ , but not D:\my\path:C:\my\path or D:\:C:\my\path .
sourcePath (string) --
When the host parameter is used, specify a sourcePath to declare the path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If the host parameter contains a sourcePath file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the sourcePath value doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
If you're using the Fargate launch type, the sourcePath parameter is not supported.
dockerVolumeConfiguration (dict) --
This parameter is specified when you use Docker volumes.
Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.
Note
Docker volumes aren't supported by tasks run on Fargate.
scope (string) --
The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.
autoprovision (boolean) --
If this value is true , the Docker volume is created if it doesn't already exist.
Note
This field is only used if the scope is shared .
driver (string) --
The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. For more information, see Docker plugin discovery. This parameter maps to Driver in the Create a volume section of the Docker Remote API and the xxdriver option to docker volume create.
driverOpts (dict) --
A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the Create a volume section of the Docker Remote API and the xxopt option to docker volume create.
(string) --
(string) --
labels (dict) --
Custom metadata to add to your Docker volume. This parameter maps to Labels in the Create a volume section of the Docker Remote API and the xxlabel option to docker volume create.
(string) --
(string) --
efsVolumeConfiguration (dict) --
This parameter is specified when you use an Amazon Elastic File System file system for task storage.
fileSystemId (string) --
The Amazon EFS file system ID to use.
rootDirectory (string) --
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / which will enforce the path set on the EFS access point.
transitEncryption (string) --
Determines whether to use encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be turned on if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide .
transitEncryptionPort (integer) --
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS mount helper in the Amazon Elastic File System User Guide .
authorizationConfig (dict) --
The authorization configuration details for the Amazon EFS file system.
accessPointId (string) --
The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which will enforce the path set on the EFS access point. If an access point is used, transit encryption must be on in the EFSVolumeConfiguration . For more information, see Working with Amazon EFS access points in the Amazon Elastic File System User Guide .
iam (string) --
Determines whether to use the Amazon ECS task role defined in a task definition when mounting the Amazon EFS file system. If it is turned on, transit encryption must be turned on in the EFSVolumeConfiguration . If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS access points in the Amazon Elastic Container Service Developer Guide .
fsxWindowsFileServerVolumeConfiguration (dict) --
This parameter is specified when you use Amazon FSx for Windows File Server file system for task storage.
fileSystemId (string) --
The Amazon FSx for Windows File Server file system ID to use.
rootDirectory (string) --
The directory within the Amazon FSx for Windows File Server file system to mount as the root directory inside the host.
authorizationConfig (dict) --
The authorization configuration details for the Amazon FSx for Windows File Server file system.
credentialsParameter (string) --
The authorization credential option to use. The authorization credential options can be provided using either the Amazon Resource Name (ARN) of an Secrets Manager secret or SSM Parameter Store parameter. The ARN refers to the stored credentials.
domain (string) --
A fully qualified domain name hosted by an Directory Service Managed Microsoft AD (Active Directory) or self-hosted AD on Amazon EC2.
configuredAtLaunch (boolean) --
Indicates whether the volume should be configured at launch time. This is used to create Amazon EBS volumes for standalone tasks or tasks created as part of a service. Each task definition revision may only have one volume configured at launch in the volume configuration.
To configure a volume at launch time, use this task definition revision and specify a volumeConfigurations object when calling the CreateService , UpdateService , RunTask or StartTask APIs.
status (string) --
The status of the task definition.
requiresAttributes (list) --
The container instance attributes required by your task. When an Amazon EC2 instance is registered to your cluster, the Amazon ECS container agent assigns some standard attributes to the instance. You can apply custom attributes. These are specified as key-value pairs using the Amazon ECS console or the PutAttributes API. These attributes are used when determining task placement for tasks hosted on Amazon EC2 instances. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide .
Note
This parameter isn't supported for tasks run on Fargate.
(dict) --
An attribute is a name-value pair that's associated with an Amazon ECS object. Use attributes to extend the Amazon ECS data model by adding custom metadata to your resources. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide .

(dict) --
Details on an Elastic Inference accelerator. For more information, see Working with Amazon Elastic Inference on Amazon ECS in the Amazon Elastic Container Service Developer Guide .
deviceName (string) --
The Elastic Inference accelerator device name. The deviceName must also be referenced in a container definition as a ResourceRequirement.
deviceType (string) --
The Elastic Inference accelerator type to use.
pidMode (string) --
The process namespace to use for the containers in the task. The valid values are host or task . On Fargate for Linux containers, the only valid value is task . For example, monitoring sidecars might need pidMode to access information about other containers running in the same task.
If host is specified, all containers within the tasks that specified the host PID mode on the same container instance share the same process namespace with the host Amazon EC2 instance.
If task is specified, all containers within the specified task share the same process namespace.
If no value is specified, the default is a private namespace for each container. For more information, see PID settings in the Docker run reference .
If the host PID mode is used, there's a heightened risk of undesired process namespace exposure. For more information, see Docker security.
Note
This parameter is not supported for Windows containers.
Note
This parameter is only supported for tasks that are hosted on Fargate if the tasks are using platform version 1.4.0 or later (Linux). This isn't supported for Windows containers on Fargate.
ipcMode (string) --
The IPC resource namespace to use for the containers in the task. The valid values are host , task , or none . If host is specified, then all containers within the tasks that specified the host IPC mode on the same container instance share the same IPC resources with the host Amazon EC2 instance. If task is specified, all containers within the specified task share the same IPC resources. If none is specified, then IPC resources within the containers of a task are private and not shared with other containers in a task or on the container instance. If no value is specified, then the IPC resource namespace sharing depends on the Docker daemon setting on the container instance. For more information, see IPC settings in the Docker run reference .
If the host IPC mode is used, be aware that there is a heightened risk of undesired IPC namespace expose. For more information, see Docker security.
If you are setting namespaced kernel parameters using systemControls for the containers in the task, the following will apply to your IPC resource namespace. For more information, see System Controls in the Amazon Elastic Container Service Developer Guide .
For tasks that use the host IPC mode, IPC namespace related systemControls are not supported.
For tasks that use the task IPC mode, IPC namespace related systemControls will apply to all containers within a task.
Note
This parameter is not supported for Windows containers or tasks run on Fargate.

Starts a new task using the specified task definition.
You can allow Amazon ECS to place tasks for you, or you can customize how Amazon ECS places tasks using placement constraints and placement strategies. For more information, see Scheduling Tasks in the Amazon Elastic Container Service Developer Guide .
Alternatively, you can use StartTask to use your own scheduler or place tasks manually on specific container instances.
Note
Starting April 15, 2023, Amazon Web Services will not onboard new customers to Amazon Elastic Inference (EI), and will help current customers migrate their workloads to options that offer better price and performance. After April 15, 2023, new customers will not be able to launch instances with Amazon EI accelerators in Amazon SageMaker, Amazon ECS, or Amazon EC2. However, customers who have used Amazon EI at least once during the past 30-day period are considered current customers and will be able to continue using the service.
You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide .
The Amazon ECS API follows an eventual consistency model. This is because of the distributed nature of the system supporting the API. This means that the result of an API command you run that affects your Amazon ECS resources might not be immediately visible to all subsequent commands you run. Keep this in mind when you carry out an API command that immediately follows a previous API command.
To manage eventual consistency, you can do the following:
Confirm the state of the resource before you run a command to modify it. Run the DescribeTasks command using an exponential backoff algorithm to ensure that you allow enough time for the previous command to propagate through the system. To do this, run the DescribeTasks command repeatedly, starting with a couple of seconds of wait time and increasing gradually up to five minutes of wait time.
Add wait time between subsequent commands, even if the DescribeTasks command returns an accurate response. Apply an exponential backoff algorithm starting with a couple of seconds of wait time, and increase gradually up to about five minutes of wait time.

list
The capacity provider strategy to use for the task.
If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.
When you use cluster auto scaling, you must specify capacityProviderStrategy and not launchType .
A capacity provider strategy may contain a maximum of 6 capacity providers.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
A capacity provider strategy may contain a maximum of 6 capacity providers.
capacityProvider (string) -- [REQUIRED]
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
string

boolean
Specifies whether to use Amazon ECS managed tags for the task. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide .
boolean
Determines whether to use the execute command functionality for the containers in this task. If true , this enables execute command functionality on all containers in the task.
If true , then the task definition must have a task role, or you must provide one as an override.
string
The name of the task group to associate with the task. The default value is the family name of the task definition (for example, family:my-family-name ).
string
The infrastructure to run your standalone task on. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .
The FARGATE launch type runs your tasks on Fargate On-Demand infrastructure.
Note
Fargate Spot infrastructure is available for use but a capacity provider strategy must be used. For more information, see Fargate capacity providers in the Amazon ECS User Guide for Fargate .
The EC2 launch type runs your tasks on Amazon EC2 instances registered to your cluster.
The EXTERNAL launch type runs your tasks on your on-premises server or virtual machine (VM) capacity registered to your cluster.
A task can use either a launch type or a capacity provider strategy. If a launchType is specified, the capacityProviderStrategy parameter must be omitted.
When you use cluster auto scaling, you must specify capacityProviderStrategy and not launchType .
dict
The network configuration for the task. This parameter is required for task definitions that use the awsvpc network mode to receive their own elastic network interface, and it isn't supported for other network modes. For more information, see Task networking in the Amazon Elastic Container Service Developer Guide .

The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
(string) --
assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
dict

Each line in an environment file should contain an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored.
If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they're processed from the top down. We recommend that you use unique variable names. For more information, see Specifying environment variables in the Amazon Elastic Container Service Developer Guide .

string
An optional tag specified when a task is started. For example, if you automatically trigger a task to run a batch process job, you could apply a unique identifier for that job to your task with the startedBy parameter. You can then identify which tasks belong to that job by filtering the results of a ListTasks call with the startedBy value. Up to 128 letters (uppercase and lowercase), numbers, hyphens (-), and underscores (_) are allowed.
If a task is started by an Amazon ECS service, then the startedBy parameter contains the deployment ID of the service that starts it.

The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
string
[REQUIRED]
The family and revision ( family:revision ) or full ARN of the task definition to run. If a revision isn't specified, the latest ACTIVE revision is used.
When you create a policy for run-task, you can set the resource to be the latest task definition revision, or a specific revision.
The full ARN value must match the value that you specified as the Resource of the principal's permissions policy.
When you specify the policy resource as the latest task definition version (by setting the Resource in the policy to arn:aws:ecs:us-east-1:111122223333:task-definition/TaskFamilyName ), then set this value to arn:aws:ecs:us-east-1:111122223333:task-definition/TaskFamilyName .
When you specify the policy resource as a specific task definition version (by setting the Resource in the policy to arn:aws:ecs:us-east-1:111122223333:task-definition/TaskFamilyName:1 or arn:aws:ecs:us-east-1:111122223333:task-definition/TaskFamilyName:* ), then set this value to arn:aws:ecs:us-east-1:111122223333:task-definition/TaskFamilyName:1 .

This parameter is available for both the EC2 and Fargate launch types.
This parameter is available for both the Linux and Windows operating systems.
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package
You can specify a maximum of 100 port ranges per container.

For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
The containerPortRange valid values are between 1 and 65535.
A port can only be included in one port mapping per container.
You cannot specify overlapping port ranges.
The first port in the range must be less than last port in the range.
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see Issue #11185 on the Github website. For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide .

The following rules apply when you specify a containerPortRange :
You must use either the bridge network mode or the awsvpc network mode.
This parameter is available for both the EC2 and Fargate launch types.
This parameter is available for both the Linux and Windows operating systems.
The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package
You can specify a maximum of 100 port ranges per container.
You do not specify a hostPortRange . The value of the hostPortRange is set as follows:
For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange . This is a static mapping strategy.
For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.
The containerPortRange valid values are between 1 and 65535.
A port can only be included in one port mapping per container.
You cannot specify overlapping port ranges.
The first port in the range must be less than last port in the range.
Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see Issue #11185 on the Github website. For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide .
You can call DescribeTasks to view the hostPortRange which are the host ports that are bound to the container ports.

Modifies the parameters of a service.
For services using the rolling update ( ECS ) you can update the desired count, deployment configuration, network configuration, load balancers, service registries, enable ECS managed tags option, propagate tags option, task placement constraints and strategies, and task definition. When you update any of these parameters, Amazon ECS starts new tasks with the new configuration.
You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when starting or running a task, or when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide . You can update your volume configurations and trigger a new deployment. volumeConfigurations is only supported for REPLICA service and not DAEMON service. If you leave volumeConfigurations null , it doesn't trigger a new deployment. For more infomation on volumes, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide .
For services using the blue/green ( CODE_DEPLOY ) deployment controller, only the desired count, deployment configuration, health check grace period, task placement constraints and strategies, enable ECS managed tags option, and propagate tags can be updated using this API. If the network configuration, platform version, task definition, or load balancer need to be updated, create a new CodeDeploy deployment. For more information, see CreateDeployment in the CodeDeploy API Reference .
For services using an external deployment controller, you can update only the desired count, task placement constraints and strategies, health check grace period, enable ECS managed tags option, and propagate tags option, using this API. If the launch type, load balancer, network configuration, platform version, or task definition need to be updated, create a new task set For more information, see CreateTaskSet.
You can add to or subtract from the number of instantiations of a task definition in a service by specifying the cluster that the service is running in and a new desiredCount parameter.
You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when starting or running a task, or when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide .
If you have updated the container image of your application, you can create a new task definition with that image and deploy it to your service. The service scheduler uses the minimum healthy percent and maximum percent parameters (in the service's deployment configuration) to determine the deployment strategy.
Note
If your updated Docker image uses the same tag as what is in the existing task definition for your service (for example, my_image:latest ), you don't need to create a new revision of your task definition. You can update the service using the forceNewDeployment option. The new tasks launched by the deployment pull the current image/tag combination from your repository when they start.
You can also update the deployment configuration of a service. When a deployment is triggered by updating the task definition of a service, the service scheduler uses the deployment configuration parameters, minimumHealthyPercent and maximumPercent , to determine the deployment strategy.
If minimumHealthyPercent is below 100%, the scheduler can ignore desiredCount temporarily during a deployment. For example, if desiredCount is four tasks, a minimum of 50% allows the scheduler to stop two existing tasks before starting two new tasks. Tasks for services that don't use a load balancer are considered healthy if they're in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they're in the RUNNING state and are reported as healthy by the load balancer.
The maximumPercent parameter represents an upper limit on the number of running tasks during a deployment. You can use it to define the deployment batch size. For example, if desiredCount is four tasks, a maximum of 200% starts four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available).
When UpdateService stops a task during a deployment, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM and a 30-second timeout. After this, SIGKILL is sent and the containers are forcibly stopped. If the container handles the SIGTERM gracefully and exits within 30 seconds from receiving it, no SIGKILL is sent.
When the service scheduler launches new tasks, it determines task placement in your cluster with the following logic.
Determine which of the container instances in your cluster can support your service's task definition. For example, they have the required CPU, memory, ports, and container instance attributes.
By default, the service scheduler attempts to balance tasks across Availability Zones in this manner even though you can choose a different placement strategy.
Sort the valid container instances by the fewest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have zero, valid container instances in either zone B or C are considered optimal for placement.
Place the new service task on a valid container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the fewest number of running tasks for this service.
When the service scheduler stops running tasks, it attempts to maintain balance across the Availability Zones in your cluster using the following logic:
Sort the container instances by the largest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have two, container instances in either zone B or C are considered optimal for termination.
Stop the task on a container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the largest number of running tasks for this service.
Note
You must have a service-linked role when you update any of the following service properties:
loadBalancers ,
serviceRegistries
For more information about the role see the CreateService request parameter role.

string
The short name or full Amazon Resource Name (ARN) of the cluster that your service runs on. If you do not specify a cluster, the default cluster is assumed.
string
[REQUIRED]
The name of the service to update.
integer
The number of instantiations of the task to place and keep running in your service.
string
The family and revision ( family:revision ) or full ARN of the task definition to run in your service. If a revision is not specified, the latest ACTIVE revision is used. If you modify the task definition with UpdateService , Amazon ECS spawns a task with the new version of the task definition and then stops an old task after the new version is running.
list
The capacity provider strategy to update the service to use.
if the service uses the default capacity provider strategy for the cluster, the service can be updated to use one or more capacity providers as opposed to the default capacity provider strategy. However, when a service is using a capacity provider strategy that's not the default capacity provider strategy, the service can't be updated to use the cluster's default capacity provider strategy.
A capacity provider strategy consists of one or more capacity providers along with the base and weight to assign to them. A capacity provider must be associated with the cluster to be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster. Only capacity providers with an ACTIVE or UPDATING status can be used.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used.
The PutClusterCapacityProviders API operation is used to update the list of available capacity providers for a cluster after the cluster is created.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
A capacity provider strategy may contain a maximum of 6 capacity providers.
capacityProvider (string) -- [REQUIRED]
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
dict
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker (dict) --
Note
The deployment circuit breaker can only be used for services using the rolling update ( ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable (boolean) -- [REQUIRED]
Determines whether to use the deployment circuit breaker logic for the service.
rollback (boolean) -- [REQUIRED]
Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
minimumHealthyPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.
For services that do not use a load balancer, the following should be noted:
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services are that do use a load balancer, the following should be noted:
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.
alarms (dict) --
Information about the CloudWatch alarms.
alarmNames (list) -- [REQUIRED]
One or more CloudWatch alarm names. Use a "," to separate the alarms.
(string) --
enable (boolean) -- [REQUIRED]
Determines whether to use the CloudWatch alarm option in the service deployment process.
rollback (boolean) -- [REQUIRED]
Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is used, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
dict
An object representing the network configuration for the service.
awsvpcConfiguration (dict) --
The VPC subnets and security groups that are associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
subnets (list) -- [REQUIRED]
The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per AwsVpcConfiguration .
Note
All specified subnets must be from the same VPC.
(string) --
securityGroups (list) --
The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
(string) --
assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
list
An array of task placement constraint objects to update the service to use. If no value is specified, the existing placement constraints for the service will remain unchanged. If this value is specified, it will override any existing placement constraints defined for the service. To remove all existing placement constraints, specify an empty array.
You can specify a maximum of 10 constraints for each task. This limit includes constraints in the task definition and those specified at runtime.
(dict) --
An object representing a constraint on task placement. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide .
Note
If you're using the Fargate launch type, task placement constraints aren't supported.
type (string) --
The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
expression (string) --
A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is distinctInstance . For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .
list
The task placement strategy objects to update the service to use. If no value is specified, the existing placement strategy for the service will remain unchanged. If this value is specified, it will override the existing placement strategy defined for the service. To remove an existing placement strategy, specify an empty object.
You can specify a maximum of five strategy rules for each service.
(dict) --
The task placement strategy for a task or service. For more information, see Task placement strategies in the Amazon Elastic Container Service Developer Guide .
type (string) --
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.
field (string) --
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.
string
The platform version that your tasks in the service run on. A platform version is only specified for tasks using the Fargate launch type. If a platform version is not specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
boolean
Determines whether to force a new deployment of the service. By default, deployments aren't forced. You can use this option to start a new deployment with no service definition changes. For example, you can update a service's tasks to use a newer Docker image with the same image/tag combination ( my_image:latest ) or to roll Fargate tasks onto a newer platform version.
integer
The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started. This is only valid if your service is configured to use a load balancer. If your service's tasks take a while to start and respond to Elastic Load Balancing health checks, you can specify a health check grace period of up to 2,147,483,647 seconds. During that time, the Amazon ECS service scheduler ignores the Elastic Load Balancing health check status. This grace period can prevent the ECS service scheduler from marking tasks as unhealthy and stopping them before they have time to come up.
boolean
If true , this enables execute command functionality on all task containers.
If you do not want to override the value that was set when the service was created, you can set this to null when performing this action.
boolean
Determines whether to turn on Amazon ECS managed tags for the tasks in the service. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide .
Only tasks launched after the update will reflect the update. To update the tags on all tasks, set forceNewDeployment to true , so that Amazon ECS starts new tasks with the updated tags.
list
A list of Elastic Load Balancing load balancer objects. It contains the load balancer name, the container name, and the container port to access from the load balancer. The container name is as it appears in a container definition.
When you add, update, or remove a load balancer configuration, Amazon ECS starts new tasks with the updated Elastic Load Balancing configuration, and then stops the old tasks when the new tasks are running.
For services that use rolling updates, you can add, update, or remove Elastic Load Balancing target groups. You can update from a single target group to multiple target groups and from multiple target groups to a single target group.
For services that use blue/green deployments, you can update Elastic Load Balancing target groups by using CreateDeployment through CodeDeploy. Note that multiple target groups are not supported for blue/green deployments. For more information see Register multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .
For services that use the external deployment controller, you can add, update, or remove load balancers by using CreateTaskSet. Note that multiple target groups are not supported for external deployments. For more information see Register multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .
You can remove existing loadBalancers by passing an empty list.
(dict) --
The load balancer configuration to use with a service or task set.
When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.
We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.
A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.
string
Determines whether to propagate the tags from the task definition or the service to the task. If no value is specified, the tags aren't propagated.
Only tasks launched after the update will reflect the update. To update the tags on all tasks, set forceNewDeployment to true , so that Amazon ECS starts new tasks with the updated tags.
list
The details for the service discovery registries to assign to this service. For more information, see Service Discovery.
When you add, update, or remove the service registries configuration, Amazon ECS starts new tasks with the updated service registries configuration, and then stops the old tasks when the new tasks are running.
You can remove existing serviceRegistries by passing an empty list.
(dict) --
The details for the service registry.
Each service may be associated with one service registry. Multiple service registries for each service are not supported.
When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.
port (integer) --
The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
containerPort (integer) --
The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
dict
The configuration for this service to discover and connect to services, and be discovered by, and connected from, other services within a namespace.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
enabled (boolean) -- [REQUIRED]
Specifies whether to use Service Connect with this service.
namespace (string) --
The namespace name or full Amazon Resource Name (ARN) of the Cloud Map namespace for use with Service Connect. The namespace must be in the same Amazon Web Services Region as the Amazon ECS service and cluster. The type of namespace doesn't affect Service Connect. For more information about Cloud Map, see Working with Services in the Cloud Map Developer Guide .
services (list) --
The list of Service Connect service objects. These are names and aliases (also known as endpoints) that are used by other Amazon ECS services to connect to this service.
This field is not required for a "client" Amazon ECS service that's a member of a namespace only to connect to other services within the namespace. An example of this would be a frontend application that accepts incoming requests from either a load balancer that's attached to the service or by other means.
An object selects a port from the task definition, assigns a name for the Cloud Map service, and a list of aliases (endpoints) and ports for client applications to refer to this service.
(dict) --
The Service Connect service object configuration. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
portName (string) -- [REQUIRED]
The portName must match the name of one of the portMappings from all the containers in the task definition of this Amazon ECS service.
discoveryName (string) --
The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.
If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .
clientAliases (list) --
The list of client aliases for this Service Connect service. You use these to assign names that can be used by client applications. The maximum number of client aliases that you can have in this list is 1.
Each alias ("endpoint") is a fully-qualified name and port number that other Amazon ECS tasks ("clients") can use to connect to this service.
Each name and port mapping must be unique within the namespace.
For each ServiceConnectService , you must provide at least one clientAlias with one port .
(dict) --
Each alias ("endpoint") is a fully-qualified name and port number that other tasks ("clients") can use to connect to this service.
Each name and port mapping must be unique within the namespace.
Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
port (integer) -- [REQUIRED]
The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.
To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
dnsName (string) --
The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.
If this parameter isn't specified, the default value of discoveryName.namespace is used. If the discoveryName isn't specified, the port mapping name from the task definition is used in portName.namespace .
To avoid changing your applications in client Amazon ECS services, set this to the same name that the client application uses by default. For example, a few common names are database , db , or the lowercase name of a database, such as mysql or redis . For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
ingressPortOverride (integer) --
The port number for the Service Connect proxy to listen on.
Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.
In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.
logConfiguration (dict) --
The log configuration for the container. This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run.
By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition. For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Understand the following when specifying a log configuration for your containers.
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent. For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens . For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide .
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.
logDriver (string) -- [REQUIRED]
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'
(string) --
(string) --
secretOptions (list) --
The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.
To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.
For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
name (string) -- [REQUIRED]
The name of the secret.
valueFrom (string) -- [REQUIRED]
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.
For information about the require Identity and Access Management permissions, see Required IAM permissions for Amazon ECS secrets (for Secrets Manager) or Required IAM permissions for Amazon ECS secrets (for Systems Manager Parameter store) in the Amazon Elastic Container Service Developer Guide .
Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
list
The details of the volume that was configuredAtLaunch . You can configure the size, volumeType, IOPS, throughput, snapshot and encryption in ServiceManagedEBSVolumeConfiguration. The name of the volume must match the name from the task definition. If set to null, no new deployment is triggered. Otherwise, if this configuration differs from the existing one, it triggers a new deployment.
(dict) --
The configuration for a volume specified in the task definition as a volume that is configured at launch time. Currently, the only supported volume type is an Amazon EBS volume.
name (string) -- [REQUIRED]
The name of the volume. This value must match the volume name from the Volume object in the task definition.
managedEBSVolume (dict) --
The configuration for the Amazon EBS volume that Amazon ECS creates and manages on your behalf. These settings are used to create each Amazon EBS volume, with one volume created for each task in the service. The Amazon EBS volumes are visible in your account in the Amazon EC2 console once they are created.
encrypted (boolean) --
Indicates whether the volume should be encrypted. If no value is specified, encryption is turned on by default. This parameter maps 1:1 with the Encrypted parameter of the CreateVolume API in the Amazon EC2 API Reference .
kmsKeyId (string) --
The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference .
Warning
Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.
volumeType (string) --
The volume type. This parameter maps 1:1 with the VolumeType parameter of the CreateVolume API in the Amazon EC2 API Reference . For more information, see Amazon EBS volume types in the Amazon EC2 User Guide .
The following are the supported volume types.
General Purpose SSD: gp2 | gp3
Provisioned IOPS SSD: io1 | io2
Throughput Optimized HDD: st1
Cold HDD: sc1
Magnetic: standard
Note
The magnetic volume type is not supported on Fargate.
sizeInGiB (integer) --
The size of the volume in GiB. You must specify either a volume size or a snapshot ID. If you specify a snapshot ID, the snapshot size is used for the volume size by default. You can optionally specify a volume size greater than or equal to the snapshot size. This parameter maps 1:1 with the Size parameter of the CreateVolume API in the Amazon EC2 API Reference .
The following are the supported volume size values for each volume type.
gp2 and gp3 : 1-16,384
io1 and io2 : 4-16,384
st1 and sc1 : 125-16,384
standard : 1-1,024
snapshotId (string) --
The snapshot that Amazon ECS uses to create the volume. You must specify either a snapshot ID or a volume size. This parameter maps 1:1 with the SnapshotId parameter of the CreateVolume API in the Amazon EC2 API Reference .
iops (integer) --
The number of I/O operations per second (IOPS). For gp3 , io1 , and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.
The following are the supported values for each volume type.
gp3 : 3,000 - 16,000 IOPS
io1 : 100 - 64,000 IOPS
io2 : 100 - 256,000 IOPS
This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS . This parameter is not supported for st1 , sc1 , or standard volume types.
This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference .
throughput (integer) --
The throughput to provision for a volume, in MiB/s, with a maximum of 1,000 MiB/s. This parameter maps 1:1 with the Throughput parameter of the CreateVolume API in the Amazon EC2 API Reference .
Warning
This parameter is only supported for the gp3 volume type.
tagSpecifications (list) --
The tags to apply to the volume. Amazon ECS applies service-managed tags by default. This parameter maps 1:1 with the TagSpecifications.N parameter of the CreateVolume API in the Amazon EC2 API Reference .
(dict) --
The tag specifications of an Amazon EBS volume.
resourceType (string) -- [REQUIRED]
The type of volume resource.
tags (list) --
The tags applied to this Amazon EBS volume. AmazonECSCreated and AmazonECSManaged are reserved tags that can't be used.
(dict) --
The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value. You define them.
The following basic restrictions apply to tags:
Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
propagateTags (string) --
Determines whether to propagate the tags from the task definition to the Amazon EBS volume. Tags can only propagate to a SERVICE specified in ServiceVolumeConfiguration . If no value is specified, the tags aren't propagated.
roleArn (string) -- [REQUIRED]
The ARN of the IAM role to associate with this volume. This is the Amazon ECS infrastructure IAM role that is used to manage your Amazon Web Services infrastructure. We recommend using the Amazon ECS-managed AmazonECSInfrastructureRolePolicyForVolumes IAM policy with this role. For more information, see Amazon ECS infrastructure IAM role in the Amazon ECS Developer Guide .
filesystemType (string) --
The Linux filesystem type for the volume. For volumes created from a snapshot, you must specify the same filesystem type that the volume was using when the snapshot was created. If there is a filesystem type mismatch, the task will fail to start.
The available filesystem types are ext3 , ext4 , and xfs . If no value is specified, the xfs filesystem type is used by default.

Response Structure
(dict) --
service (dict) --
The full description of your service following the update call.
serviceArn (string) --
The ARN that identifies the service. For more information about the ARN format, see Amazon Resource Name (ARN) in the Amazon ECS Developer Guide .
serviceName (string) --
The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster. However, you can have similarly named services in multiple clusters within a Region or across multiple Regions.
clusterArn (string) --
The Amazon Resource Name (ARN) of the cluster that hosts the service.
loadBalancers (list) --
A list of Elastic Load Balancing load balancer objects. It contains the load balancer name, the container name, and the container port to access from the load balancer. The container name is as it appears in a container definition.
(dict) --
The load balancer configuration to use with a service or task set.
When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.
We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.
A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.
containerName (string) --
The name of the container (as it appears in a container definition) to associate with the load balancer.
containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details for the service discovery registries to assign to this service. For more information, see Service Discovery.
(dict) --
The details for the service registry.
Each service may be associated with one service registry. Multiple service registries for each service are not supported.
When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.
port (integer) --
The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
containerPort (integer) --
The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
status (string) --
The status of the service. The valid values are ACTIVE , DRAINING , or INACTIVE .
desiredCount (integer) --
The desired number of instantiations of the task definition to keep running on the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
runningCount (integer) --
The number of tasks in the cluster that are in the RUNNING state.
pendingCount (integer) --
The number of tasks in the cluster that are in the PENDING state.
launchType (string) --
The launch type the service is using. When using the DescribeServices API, this field is omitted if the service was created using a capacity provider strategy.
capacityProviderStrategy (list) --
The capacity provider strategy the service uses. When using the DescribeServices API, this field is omitted if the service was created using a launch type.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
A capacity provider strategy may contain a maximum of 6 capacity providers.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.
platformVersion (string) --
The platform version to run your service on. A platform version is only specified for tasks that are hosted on Fargate. If one isn't specified, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
platformFamily (string) --
The operating system that your tasks in the service run on. A platform family is specified only for tasks using the Fargate launch type.
All tasks that run as part of this service must use the same platformFamily value as the service (for example, LINUX ).
taskDefinition (string) --
The task definition to use for tasks in the service. This value is specified when the service is created with CreateService, and it can be modified with UpdateService.
deploymentConfiguration (dict) --
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
deploymentCircuitBreaker (dict) --
Note
The deployment circuit breaker can only be used for services using the rolling update ( ECS ) deployment type.
The deployment circuit breaker determines whether a service deployment will fail if the service can't reach a steady state. If you use the deployment circuit breaker, a service deployment will transition to a failed state and stop launching new tasks. If you use the rollback option, when a service deployment fails, the service is rolled back to the last deployment that completed successfully. For more information, see Rolling update in the Amazon Elastic Container Service Developer Guide
enable (boolean) --
Determines whether to use the deployment circuit breaker logic for the service.
rollback (boolean) --
Determines whether to configure Amazon ECS to roll back the service if a service deployment fails. If rollback is on, when a service deployment fails, the service is rolled back to the last deployment that completed successfully.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service is using the REPLICA service scheduler and has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler may start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default maximumPercent value for a service using the REPLICA service scheduler is 200%.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and tasks that use the EC2 launch type, the maximum percent value is set to the default value and is used to define the upper limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If the tasks in the service use the Fargate launch type, the maximum percent value is not used, although it is returned when describing your service.
minimumHealthyPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, the minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the service scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks.
For services that do not use a load balancer, the following should be noted:
A service is considered healthy if all essential containers within the tasks in the service pass their health checks.
If a task has no essential containers with a health check defined, the service scheduler will wait for 40 seconds after a task reaches a RUNNING state before the task is counted towards the minimum healthy percent total.
If a task has one or more essential containers with a health check defined, the service scheduler will wait for the task to reach a healthy status before counting it towards the minimum healthy percent total. A task is considered healthy when all essential containers within the task have passed their health checks. The amount of time the service scheduler can wait for is determined by the container health check settings.
For services are that do use a load balancer, the following should be noted:
If a task has no essential containers with a health check defined, the service scheduler will wait for the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a task has an essential container with a health check defined, the service scheduler will wait for both the task to reach a healthy status and the load balancer target group health check to return a healthy status before counting the task towards the minimum healthy percent total.
If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the EC2 launch type, the minimum healthy percent value is set to the default value and is used to define the lower limit on the number of the tasks in the service that remain in the RUNNING state while the container instances are in the DRAINING state. If a service is using either the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and is running tasks that use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

alarmNames (list) --
One or more CloudWatch alarm names. Use a "," to separate the alarms.
(string) --
enable (boolean) --

externalId (string) --
The external ID associated with the task set.
If an CodeDeploy deployment created a task set, the externalId parameter contains the CodeDeploy deployment ID.
If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID Cloud Map attribute.
status (string) --
The status of the task set. The following describes each state.
PRIMARY
The task set is serving production traffic.
ACTIVE
The task set isn't serving production traffic.
DRAINING
The tasks in the task set are being stopped, and their corresponding targets are being deregistered from their target group.
taskDefinition (string) --
The task definition that the task set is using.
computedDesiredCount (integer) --
The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.
pendingCount (integer) --
The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it's restarted after being in the STOPPED state.
runningCount (integer) --
The number of tasks in the task set that are in the RUNNING status during a deployment. A task in the RUNNING state is running and ready for use.
createdAt (datetime) --
The Unix timestamp for the time when the task set was created.
updatedAt (datetime) --
The Unix timestamp for the time when the task set was last updated.
launchType (string) --
The launch type the tasks in the task set are using. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .
capacityProviderStrategy (list) --
The capacity provider strategy that are associated with the task set.
(dict) --
The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.
Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.
If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateCapacityProvider API operation.
To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.
A capacity provider strategy may contain a maximum of 6 capacity providers.
capacityProvider (string) --
The short name of the capacity provider.
weight (integer) --
The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.
If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can't be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.
An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that's run using capacityProviderA , four tasks would use capacityProviderB .
base (integer) --
The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

Details on a load balancer that are used with a task set.
(dict) --
The load balancer configuration to use with a service or task set.
When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.
We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.
A service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles in the Amazon Elastic Container Service Developer Guide .
targetGroupArn (string) --
The full Amazon Resource Name (ARN) of the Elastic Load Balancing target group or groups associated with a service or task set.
A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer.
For services using the ECS deployment controller, you can specify one or multiple target groups. For more information, see Registering multiple target groups with a service in the Amazon Elastic Container Service Developer Guide .
For services using the CODE_DEPLOY deployment controller, you're required to define two target groups for the load balancer. For more information, see Blue/green deployment with CodeDeploy in the Amazon Elastic Container Service Developer Guide .
Warning
If your service's task definition uses the awsvpc network mode, you must choose ip as the target type, not instance . Do this when creating your target groups because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance. This network mode is required for the Fargate launch type.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
If you are using an Application Load Balancer or a Network Load Balancer the load balancer name parameter should be omitted.

containerPort (integer) --
The port on the container to associate with the load balancer. This port must correspond to a containerPort in the task definition the tasks in the service are using. For tasks that use the EC2 launch type, the container instance they're launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details for the service discovery registries to assign to this task set. For more information, see Service discovery.
(dict) --
The details for the service registry.
Each service may be associated with one service registry. Multiple service registries for each service are not supported.
When you add, update, or remove the service registries configuration, Amazon ECS starts a new deployment. New tasks are registered and deregistered to the updated service registry configuration.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is Cloud Map. For more information, see CreateService.
port (integer) --
The port value used if your service discovery service specified an SRV record. This field might be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value to be used for your service discovery service. It's already specified in the task definition. If the task definition that your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition that your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.
containerPort (integer) --
The port value to be used for your service discovery service. It's already specified in the task definition. If the task definition your service task specifies uses the bridge or host network mode, you must specify a containerName and containerPort combination from the task definition. If the task definition your service task specifies uses the awsvpc network mode and a type SRV DNS record is used, you must specify either a containerName and containerPort combination or a port value. However, you can't specify both.

The Unix timestamp for the time when the task set stability status was retrieved.
tags (list) --
The metadata that you apply to the task set to help you categorize and organize them. Each tag consists of a key and an optional value. You define both.
The following basic restrictions apply to tags:
Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

Tasks that run in a namespace can use short names to connect to services in the namespace. Tasks can connect to services across all of the clusters in the namespace. Tasks connect through a managed proxy container that collects logs and metrics for increased visibility. Only the tasks that Amazon ECS services create are supported with Service Connect. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
port (integer) --
The listening port number for the Service Connect proxy. This port is available inside of all of the tasks within the same namespace.
To avoid changing your applications in client Amazon ECS services, set this to the same port that the client application uses by default. For more information, see Service Connect in the Amazon Elastic Container Service Developer Guide .
dnsName (string) --
The dnsName is the name that you use in the applications of client tasks to connect to this service. The name must be a valid DNS name but doesn't need to be fully-qualified. The name can include up to 127 characters. The name can include lowercase letters, numbers, underscores (_), hyphens (-), and periods (.). The name can't start with a hyphen.

The port number for the Service Connect proxy to listen on.
Use the value of this field to bypass the proxy for traffic on the port number specified in the named portMapping in the task definition of this application, and then use it in your VPC security groups to allow traffic into the proxy for this Amazon ECS service.
In awsvpc mode and Fargate, the default value is the container port number. The container port number is in the portMapping in the task definition. In bridge mode, the default value is the ephemeral port of the Service Connect proxy.
logConfiguration (dict) --
The log configuration for the container. This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run.
By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver configuration in the container definition. For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Understand the following when specifying a log configuration for your containers.
Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon. Additional log drivers may be available in future releases of the Amazon ECS container agent. For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens . For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance.
For tasks that are hosted on Amazon EC2 instances, the Amazon ECS container agent must register the available logging drivers with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS container agent configuration in the Amazon Elastic Container Service Developer Guide .
For tasks that are on Fargate, because you don't have access to the underlying infrastructure your tasks are hosted on, any additional software needed must be installed outside of the task. For example, the Fluentd output aggregators or a remote host running Logstash to send Gelf logs to.
logDriver (string) --
The log driver to use for the container.
For tasks on Fargate, the supported log drivers are awslogs , splunk , and awsfirelens .
For tasks hosted on Amazon EC2 instances, the supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , splunk , and awsfirelens .
For more information about using the awslogs log driver, see Using the awslogs log driver in the Amazon Elastic Container Service Developer Guide .
For more information about using the awsfirelens log driver, see Custom log routing in the Amazon Elastic Container Service Developer Guide .
Note
If you have a custom driver that isn't listed, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you would like to have included. However, we don't currently provide support for running modified copies of this software.
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance.

The secrets to pass to the log configuration. For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
(dict) --
An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:
To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.
To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.
For more information, see Specifying sensitive data in the Amazon Elastic Container Service Developer Guide .
name (string) --
The name of the secret.
valueFrom (string) --
The secret to expose to the container. The supported values are either the full ARN of the Secrets Manager secret or the full ARN of the parameter in the SSM Parameter Store.

Note
If the SSM Parameter Store parameter exists in the same Region as the task you're launching, then you can use either the full ARN or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
serviceConnectResources (list) --
The list of Service Connect resources that are associated with this deployment. Each list entry maps a discovery name to a Cloud Map service name.
(dict) --
The Service Connect resource. Each configuration maps a discovery name to a Cloud Map service name. The data is stored in Cloud Map as part of the Service Connect configuration for each discovery name of this Amazon ECS service.
A task can resolve the dnsName for each of the clientAliases of a service. However a task can't resolve the discovery names. If you want to connect to a service, refer to the ServiceConnectConfiguration of that service for the list of clientAliases that you can use.
discoveryName (string) --
The discovery name of this Service Connect resource.
The discoveryName is the name of the new Cloud Map service that Amazon ECS creates for this Amazon ECS service. This must be unique within the Cloud Map namespace. The name can contain up to 64 characters. The name can include lowercase letters, numbers, underscores (_), and hyphens (-). The name can't start with a hyphen.

The following are the supported values for each volume type.
gp3 : 3,000 - 16,000 IOPS
io1 : 100 - 64,000 IOPS
io2 : 100 - 256,000 IOPS
This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS . This parameter is not supported for st1 , sc1 , or standard volume types.
This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference .
throughput (integer) --
The throughput to provision for a volume, in MiB/s, with a maximum of 1,000 MiB/s. This parameter maps 1:1 with the Throughput parameter of the CreateVolume API in the Amazon EC2 API Reference .
Warning
This parameter is only supported for the gp3 volume type.
tagSpecifications (list) --
The tags to apply to the volume. Amazon ECS applies service-managed tags by default. This parameter maps 1:1 with the TagSpecifications.N parameter of the CreateVolume API in the Amazon EC2 API Reference .
(dict) --
The tag specifications of an Amazon EBS volume.
resourceType (string) --
The type of volume resource.
tags (list) --
The tags applied to this Amazon EBS volume. AmazonECSCreated and AmazonECSManaged are reserved tags that can't be used.
(dict) --
The metadata that you apply to a resource to help you categorize and organize them. Each tag consists of a key and an optional value. You define them.
The following basic restrictions apply to tags:
Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.
Tag keys and values are case-sensitive.
Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.
key (string) --
One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.
value (string) --
The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).
propagateTags (string) --
Determines whether to propagate the tags from the task definition to the Amazon EBS volume. Tags can only propagate to a SERVICE specified in ServiceVolumeConfiguration . If no value is specified, the tags aren't propagated.
roleArn (string) --
The ARN of the IAM role to associate with this volume. This is the Amazon ECS infrastructure IAM role that is used to manage your Amazon Web Services infrastructure. We recommend using the Amazon ECS-managed AmazonECSInfrastructureRolePolicyForVolumes IAM policy with this role. For more information, see Amazon ECS infrastructure IAM role in the Amazon ECS Developer Guide .
filesystemType (string) --
The Linux filesystem type for the volume. For volumes created from a snapshot, you must specify the same filesystem type that the volume was using when the snapshot was created. If there is a filesystem type mismatch, the task will fail to start.
The available filesystem types are ext3 , ext4 , and xfs . If no value is specified, the xfs filesystem type is used by default.
roleArn (string) --
The ARN of the IAM role that's associated with the service. It allows the Amazon ECS container agent to register container instances with an Elastic Load Balancing load balancer.
events (list) --
The event stream for your service. A maximum of 100 of the latest events are displayed.
(dict) --
The details for an event that's associated with a service.
id (string) --
The ID string for the event.
createdAt (datetime) --
The Unix timestamp for the time when the event was triggered.
message (string) --
The event message.
createdAt (datetime) --
The Unix timestamp for the time when the service was created.
placementConstraints (list) --
The placement constraints for the tasks in the service.
(dict) --
An object representing a constraint on task placement. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide .
Note
If you're using the Fargate launch type, task placement constraints aren't supported.
type (string) --
The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.
expression (string) --
A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can't specify an expression if the constraint type is distinctInstance . For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .
placementStrategy (list) --
The placement strategy that determines how tasks for the service are placed.
(dict) --
The task placement strategy for a task or service. For more information, see Task placement strategies in the Amazon Elastic Container Service Developer Guide .
type (string) --
The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that's specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.
field (string) --
The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that's applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.
networkConfiguration (dict) --
The VPC subnet and security group configuration for tasks that receive their own elastic network interface by using the awsvpc networking mode.
awsvpcConfiguration (dict) --
The VPC subnets and security groups that are associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
subnets (list) --
The IDs of the subnets associated with the task or service. There's a limit of 16 subnets that can be specified per AwsVpcConfiguration .
Note
All specified subnets must be from the same VPC.
(string) --
securityGroups (list) --
The IDs of the security groups associated with the task or service. If you don't specify a security group, the default security group for the VPC is used. There's a limit of 5 security groups that can be specified per AwsVpcConfiguration .
Note
All specified security groups must be from the same VPC.
(string) --
assignPublicIp (string) --
Whether the task's elastic network interface receives a public IP address. The default value is DISABLED .
healthCheckGracePeriodSeconds (integer) --
The period of time, in seconds, that the Amazon ECS service scheduler ignores unhealthy Elastic Load Balancing target health checks after a task has first started.
schedulingStrategy (string) --
The scheduling strategy to use for the service. For more information, see Services.
There are two service scheduler strategies available.
REPLICA -The replica scheduling strategy places and maintains the desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions.
DAEMON -The daemon scheduling strategy deploys exactly one task on each active container instance. This task meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It stop tasks that don't meet the placement constraints.
Note
Fargate tasks don't support the DAEMON scheduling strategy.
deploymentController (dict) --
The deployment controller type the service is using.
type (string) --
The deployment controller type to use.
There are three deployment controller types available:
ECS
The rolling update ( ECS ) deployment type involves replacing the current running version of the container with the latest version. The number of containers Amazon ECS adds or removes from the service during a rolling update is controlled by adjusting the minimum and maximum number of healthy tasks allowed during a service deployment, as specified in the DeploymentConfiguration.
CODE_DEPLOY
The blue/green ( CODE_DEPLOY ) deployment type uses the blue/green deployment model powered by CodeDeploy, which allows you to verify a new deployment of a service before sending production traffic to it.
EXTERNAL
The external ( EXTERNAL ) deployment type enables you to use any third-party deployment controller for full control over the deployment process for an Amazon ECS service.
tags (list) --
The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value. You define bot the key and value.
The following basic restrictions apply to tags:
Maximum number of tags per resource - 50
For each resource, each tag key must be unique, and each tag key can have only one value.
Maximum key length - 128 Unicode characters in UTF-8
Maximum value length - 256 Unicode characters in UTF-8
