2020/01/24 - Amazon EC2 Container Service - 9 updated api methods
Changes This release provides support for tagging Amazon ECS task sets for services using external deployment controllers.
{'service': {'taskSets': {'tags': [{'key': 'string', 'value': 'string'}]}}}
Runs and maintains a 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 UpdateService.
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 .
Tasks for services that do not use a load balancer are considered healthy if they're in the RUNNING state. Tasks for services that do use a load balancer are considered healthy if they're in the RUNNING state and the container instance that they're hosted on is reported as healthy by the load balancer.
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. 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. 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 triggered by changing properties, such as the task definition or the desired count of a service, 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 is using 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, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a 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. Tasks for services that do not use a load balancer are considered healthy if they're in the RUNNING state. Tasks for services that do use a load balancer are considered healthy if they're in the RUNNING state and they're reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using 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, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to 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 is using 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 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, although 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 in your cluster using 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 (although you can choose a different placement strategy) with the placementStrategy parameter):
Sort the valid container instances, giving priority to instances that have the fewest number of running tasks for this service in their respective Availability Zone. 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.

string
The short name or full Amazon Resource Name (ARN) of the cluster on which to run your service. 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, 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 is not specified, the latest ACTIVE revision is used.
A task definition must be specified if the service is using the ECS deployment controller.
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 is using the rolling update ( ECS ) deployment controller and using either an Application Load Balancer or Network Load Balancer, you can specify multiple target groups to attach to the service. The service-linked role is required for services that make use of 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 is using the CODE_DEPLOY deployment controller, the service is required to use either an Application Load Balancer or Network Load Balancer. When creating an AWS CodeDeploy deployment group, you specify two target groups (referred to as a targetGroupPair ). During a deployment, AWS CodeDeploy determines which task set in your service has the status PRIMARY and associates one target group with it, and then 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 allows you perform validation tests with Lambda functions before routing production traffic to it.
After you create a service using the ECS deployment controller, the load balancer name or target group ARN, container name, and container port specified in the service definition are immutable. If you are using 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 (as it appears in a container definition), and the container port to access from the load balancer. 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 specified here.
For Classic Load Balancers, this object must contain the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer. When a task from this service is placed on a container instance, the container instance is registered with the load balancer 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 are not supported. Also, when you create any target groups for these services, you must choose ip as the target type, not instance , because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.
(dict) --
Details on the load balancer or load balancers to use with a service or task set.
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. If you are using a Classic Load Balancer this should be omitted.
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 are 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 (which is required for the Fargate launch type), you must choose ip as the target type, not instance , 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.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer this 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 are launched on must allow ingress traffic on the hostPort of the port mapping.
list
The details of the service discovery registries to assign to this service. For more information, see Service Discovery.
Note
Service discovery is supported for Fargate tasks if you are using platform version v1.1.0 or later. For more information, see AWS Fargate Platform Versions.
(dict) --
Details of the service registry.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is AWS Cloud Map. For more information, see CreateService.
port (integer) --
The port value used if your service discovery service specified an SRV record. This field may be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
integer
The number of instantiations of the specified task definition to place and keep running on your cluster.
This is required if schedulingStrategy is REPLICA or is not specified. If schedulingStrategy is DAEMON then this is not required.
string
Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Up to 32 ASCII characters are allowed.
string
The launch type on which to run your service. For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide .
If a launchType is specified, the capacityProviderStrategy parameter must be omitted.
list
The capacity provider strategy to use for the service.
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 a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is 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 AWS Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The AWS 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.
capacityProvider (string) -- [REQUIRED]
The short name or full Amazon Resource Name (ARN) 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.
For example, if you have 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 is 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.
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 by default. For more information, see AWS 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 does not 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 by default 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 should not 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.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, 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, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to 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 is using 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 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, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and 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 the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.
list
An array of placement constraint objects to use for tasks in your service. You can specify a maximum of 10 constraints per 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 are using the Fargate launch type, task placement constraints are not 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. You cannot 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 five strategy rules per 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 is 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 is 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 is not 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 associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
subnets (list) -- [REQUIRED]
The subnets associated with the task or service. There is 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 security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is 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 should ignore 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 ECS service scheduler ignores 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.
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 is using 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. 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.
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 AWS 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 AWS 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 enable 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 .
string
Specifies whether to propagate the tags from the task definition or the service to the tasks in the service. If no value is specified, the tags are not propagated. Tags can only be propagated to the tasks within the service during service creation. To add tags to a task after service creation, use the TagResource API action.

Response Structure
(dict) --
service (dict) --
The full description of your service following the create call.
If a service is using the ECS deployment controller, the deploymentController and taskSets parameters will not be returned.
If the service is using 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. The ARN contains the arn:aws:ecs namespace, followed by the Region of the service, the AWS account ID of the service owner, the service namespace, and then the service name. For example, arn:aws:ecs:region:012345678910:service/my-service .
serviceName (string) --
The name of your service. Up to 255 letters (uppercase and lowercase), numbers, 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.
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, containing the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer.
(dict) --
Details on the load balancer or load balancers to use with a service or task set.
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. If you are using a Classic Load Balancer this should be omitted.
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 are 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 (which is required for the Fargate launch type), you must choose ip as the target type, not instance , 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.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer this 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 are launched on must allow ingress traffic on the hostPort of the port mapping.

The details of the service discovery registries to assign to this service. For more information, see Service Discovery.
(dict) --
Details of the service registry.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is AWS Cloud Map. For more information, see CreateService.

containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
status (string) --
The status of the service. The valid values are ACTIVE , DRAINING , or INACTIVE .

The capacity provider strategy associated with the service.
(dict) --
The details of a capacity provider strategy.
capacityProvider (string) --
The short name or full Amazon Resource Name (ARN) 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.
For example, if you have 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 is 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.
platformVersion (string) --
The platform version on which to run your service. A platform version is only specified for tasks using the Fargate launch type. If one is not specified, the LATEST platform version is used by default. For more information, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
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.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, 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, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to 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 is using 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 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, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and 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 the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

The task definition for the tasks in the task set to use.
dict
An object representing the network configuration for a task or service.
awsvpcConfiguration (dict) --
The VPC subnets and security groups associated with a task.
Note
All specified subnets and security groups must be from the same VPC.

The subnets associated with the task or service. There is 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 security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is 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
A load balancer object representing the load balancer to use with the task set. The supported load balancer types are either an Application Load Balancer or a Network Load Balancer.
(dict) --
Details on the load balancer or load balancers to use with a service or task set.
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. If you are using a Classic Load Balancer this should be omitted.
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 are 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 (which is required for the Fargate launch type), you must choose ip as the target type, not instance , 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.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer this 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 are launched on must allow ingress traffic on the hostPort of the port mapping.
list
The details of the service discovery registries to assign to this task set. For more information, see Service Discovery.
(dict) --
Details of the service registry.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is AWS Cloud Map. For more information, see CreateService.
port (integer) --
The port value used if your service discovery service specified an SRV record. This field may be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
string
The launch type that new tasks in the task set will use. For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide .
If a launchType is specified, the capacityProviderStrategy parameter must be omitted.
list
The capacity provider strategy to use for the task set.
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 a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is 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 AWS Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The AWS 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.
capacityProvider (string) -- [REQUIRED]
The short name or full Amazon Resource Name (ARN) 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.
For example, if you have 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 is 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.
string
The platform version that the tasks in the task set should use. A platform version is specified only for tasks using the Fargate launch type. If one isn't specified, the LATEST platform version is used by default.
dict
A floating-point percentage of the desired number of tasks to place and keep running in the task set.
value (float) --
The value, specified as a percent total of a service's desiredCount , to scale the task set. Accepted values are numbers between 0 and 100.
unit (string) --
The unit of measure for the scale value.
string
Unique, case-sensitive identifier that you provide to ensure the idempotency of the request. Up to 32 ASCII characters are allowed.
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, 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 AWS 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 cannot 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.

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. If you are using a Classic Load Balancer this should be omitted.
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 are 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 (which is required for the Fargate launch type), you must choose ip as the target type, not instance , 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.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer this 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 are launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details of the service discovery registries to assign to this service. For more information, see Service Discovery.
(dict) --
Details of the service registry.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is AWS Cloud Map. For more information, see CreateService.
port (integer) --

containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. 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, but not 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 on which your service is running. If no value is specified, it will default to EC2 . Valid values include EC2 and FARGATE . For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide .
capacityProviderStrategy (list) --
The capacity provider strategy associated with the service.
(dict) --
The details of a capacity provider strategy.
capacityProvider (string) --
The short name or full Amazon Resource Name (ARN) 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.
For example, if you have 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 is 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.
platformVersion (string) --
The platform version on which to run your service. A platform version is only specified for tasks using the Fargate launch type. If one is not specified, the LATEST platform version is used by default. For more information, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
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.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, 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, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to 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 is using 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 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, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and 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 the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

If a task set is created by an AWS CodeDeploy deployment, the externalId parameter contains the AWS 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 AWS 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 is not 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 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 is restarted after being in the STOPPED state.

The short name or full Amazon Resource Name (ARN) 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.
For example, if you have 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 is 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.
platformVersion (string) --
The platform version on which the tasks in the task set are running. A platform version is only specified for tasks using the Fargate launch type. If one is not specified, the LATEST platform version is used by default. For more information, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .

A target group ARN is only specified when using an Application Load Balancer or Network Load Balancer. If you are using a Classic Load Balancer this should be omitted.
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 are 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 (which is required for the Fargate launch type), you must choose ip as the target type, not instance , 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.

The container name value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
scale (dict) --
A floating-point percentage of the desired number of tasks to place and keep running in the task set.
value (float) --
The value, specified as a percent total of a service's desiredCount , to scale the task set. Accepted values are numbers between 0 and 100.

The task runningCount is equal to the computedDesiredCount .
The pendingCount is 0 .
There are no tasks running on container instances in the DRAINING status.
All tasks are reporting a healthy status from the load balancers, service discovery, and container health checks.
If any of those conditions are not met, the stability status returns STABILIZING .
stabilityStatusAt (datetime) --
The Unix timestamp for when the task set stability status was retrieved.

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 AWS 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 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. If you are using a Classic Load Balancer this should be omitted.
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 are 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 (which is required for the Fargate launch type), you must choose ip as the target type, not instance , 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.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer this should be omitted.

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 are launched on must allow ingress traffic on the hostPort of the port mapping.

containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. 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, but not 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.

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 on which your service is running. If no value is specified, it will default to EC2 . Valid values include EC2 and FARGATE . For more information, see Amazon ECS Launch Types in the Amazon Elastic Container Service Developer Guide .
capacityProviderStrategy (list) --
The capacity provider strategy associated with the service.
(dict) --
The details of a capacity provider strategy.
capacityProvider (string) --
The short name or full Amazon Resource Name (ARN) 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.
For example, if you have 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 is 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.
platformVersion (string) --
The platform version on which to run your service. A platform version is only specified for tasks using the Fargate launch type. If one is not specified, the LATEST platform version is used by default. For more information, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
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.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, 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, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to 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 is using 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 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, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and 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 the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

Modifies the parameters of a service.
For services using the rolling update ( ECS ) deployment controller, the desired count, deployment configuration, network configuration, or task definition used can be updated.
For services using the blue/green ( CODE_DEPLOY ) deployment controller, only the desired count, deployment configuration, and health check grace period can be updated using this API. If the network configuration, platform version, or task definition need to be updated, a new AWS CodeDeploy deployment should be created. For more information, see CreateDeployment in the AWS CodeDeploy API Reference .
For services using an external deployment controller, you can update only the desired count and health check grace period using this API. If the launch type, load balancer, network configuration, platform version, or task definition need to be updated, you should 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.
If you have updated the Docker 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 do not 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 do not use a load balancer are considered healthy if they are in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they are in the RUNNING state and the container instance they are hosted on is reported as healthy by the load balancer.
The maximumPercent parameter represents an upper limit on the number of running tasks during a deployment, which enables you 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 which 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 (although 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.

string
The short name or full Amazon Resource Name (ARN) of the cluster that your service is running 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 is using the default capacity provider strategy for the cluster, the service can be updated to use one or more capacity providers. However, when a service is using a non-default capacity provider strategy, the service cannot be updated to use the cluster's default capacity provider strategy.
(dict) --
The details of a capacity provider strategy.
capacityProvider (string) -- [REQUIRED]
The short name or full Amazon Resource Name (ARN) 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.
For example, if you have 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 is 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.
dict
Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, 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, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to 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 is using 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 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, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and 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 the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.
dict
An object representing the network configuration for a task or service.
awsvpcConfiguration (dict) --
The VPC subnets and security groups associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
subnets (list) -- [REQUIRED]
The subnets associated with the task or service. There is 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 security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is 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 .
string
The platform version on which your tasks in the service are running. 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 by default. For more information, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
boolean
Whether to force a new deployment of the service. Deployments are not forced by default. You can use this option to trigger 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 should ignore 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.

The ARN that identifies the service. The ARN contains the arn:aws:ecs namespace, followed by the Region of the service, the AWS account ID of the service owner, the service namespace, and then the service name. For example, arn:aws:ecs:region:012345678910:service/my-service .
serviceName (string) --
The name of your service. Up to 255 letters (uppercase and lowercase), numbers, 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.
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, containing the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer.
(dict) --
Details on the load balancer or load balancers to use with a service or task set.
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. If you are using a Classic Load Balancer this should be omitted.
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 are 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 (which is required for the Fargate launch type), you must choose ip as the target type, not instance , 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.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer this should be omitted.

The container name value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. 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, but not both.

For example, if you have 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 is 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 one is not specified, the LATEST platform version is used by default. For more information, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
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.
maximumPercent (integer) --
If a service is using the rolling update ( ECS ) deployment type, 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, as a percentage of the desired number of tasks (rounded down to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to 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 is using 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 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, as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desired number of four tasks and a minimum healthy percent of 50%, the scheduler may stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state; tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and they are reported as healthy by the load balancer. The default value for minimum healthy percent is 100%.
If a service is using the blue/green ( CODE_DEPLOY ) or EXTERNAL deployment types and 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 the tasks in the service use the Fargate launch type, the minimum healthy percent value is not used, although it is returned when describing your service.

For services using the CODE_DEPLOY deployment controller, you are 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

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 container instance in your cluster. When you are using this strategy, do not specify a desired number of tasks or any task placement strategies.
Note
Fargate tasks do not support the DAEMON scheduling strategy.
deploymentController (dict) --
The deployment controller type the service is using. When using the DescribeServices API, this field is omitted if the service is using the ECS deployment controller type.
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.

Response Structure
(dict) --
taskSet (dict) --
Information about a set of Amazon ECS tasks in either an AWS 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 the task set is created by an AWS CodeDeploy deployment, the startedBy parameter is CODE_DEPLOY . For a task set created for an external deployment, the startedBy field isn't used.
externalId (string) --
The external ID associated with the task set.
If a task set is created by an AWS CodeDeploy deployment, the externalId parameter contains the AWS 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 AWS 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 is not 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 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 is 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 when the task set was created.
updatedAt (datetime) --
The Unix timestamp for 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 associated with the task set.
(dict) --
The details of a capacity provider strategy.
capacityProvider (string) --
The short name or full Amazon Resource Name (ARN) 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.
For example, if you have 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 is 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.
platformVersion (string) --
The platform version on which the tasks in the task set are running. A platform version is only specified for tasks using the Fargate launch type. If one is not specified, the LATEST platform version is used by default. For more information, see AWS Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .
networkConfiguration (dict) --
The network configuration for the task set.
awsvpcConfiguration (dict) --
The VPC subnets and security groups associated with a task.
Note
All specified subnets and security groups must be from the same VPC.
subnets (list) --
The subnets associated with the task or service. There is 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 security groups associated with the task or service. If you do not specify a security group, the default security group for the VPC is used. There is 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 .
loadBalancers (list) --
Details on a load balancer that is used with a task set.
(dict) --
Details on the load balancer or load balancers to use with a service or task set.
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. If you are using a Classic Load Balancer this should be omitted.
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 are 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 (which is required for the Fargate launch type), you must choose ip as the target type, not instance , 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.
loadBalancerName (string) --
The name of the load balancer to associate with the Amazon ECS service or task set.
A load balancer name is only specified when using a Classic Load Balancer. If you are using an Application Load Balancer or a Network Load Balancer this 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 are launched on must allow ingress traffic on the hostPort of the port mapping.
serviceRegistries (list) --
The details of the service discovery registries to assign to this task set. For more information, see Service Discovery.
(dict) --
Details of the service registry.
registryArn (string) --
The Amazon Resource Name (ARN) of the service registry. The currently supported service registry is AWS Cloud Map. For more information, see CreateService.
port (integer) --
The port value used if your service discovery service specified an SRV record. This field may be used if both the awsvpc network mode and SRV records are used.
containerName (string) --
The container name value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
containerPort (integer) --
The port value, already specified in the task definition, to be used for your service discovery service. 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, but not both.
scale (dict) --
A floating-point percentage of the desired number of tasks to place and keep running in the task set.
value (float) --
The value, specified as a percent total of a service's desiredCount , to scale the task set. Accepted values are numbers between 0 and 100.
unit (string) --
The unit of measure for the scale value.
stabilityStatus (string) --
The stability status, which indicates whether the task set has reached a steady state. If the following conditions are met, the task set will be in STEADY_STATE :
The task runningCount is equal to the computedDesiredCount .
The pendingCount is 0 .
There are no tasks running on container instances in the DRAINING status.
All tasks are reporting a healthy status from the load balancers, service discovery, and container health checks.
If any of those conditions are not met, the stability status returns STABILIZING .
stabilityStatusAt (datetime) --
The Unix timestamp for 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, both of which you define.
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 AWS 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.
