Request Syntax
client.describe_job_definitions(
jobDefinitions=[
'string',
],
maxResults=123,
jobDefinitionName='string',
status='string',
nextToken='string'
)
list
A list of up to 100 job definition names or full Amazon Resource Name (ARN) entries.
(string) --
integer
The maximum number of results returned by DescribeJobDefinitions in paginated output. When this parameter is used, DescribeJobDefinitions only returns maxResults results in a single page and a nextToken response element. The remaining results of the initial request can be seen by sending another DescribeJobDefinitions request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then DescribeJobDefinitions returns up to 100 results and a nextToken value if applicable.
string
The name of the job definition to describe.
string
The status used to filter job definitions.
string
The nextToken value returned from a previous paginated DescribeJobDefinitions request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.
Note
This token should be treated as an opaque identifier that's only used to retrieve the next items in a list and not for other programmatic purposes.

parameters (dict) --
Default parameters or parameter substitution placeholders that are set in the job definition. Parameters are specified as a key-value pair mapping. Parameters in a SubmitJob request override any corresponding parameter defaults from the job definition. For more information about specifying parameters, see Job Definition Parameters in the AWS Batch User Guide .
(string) --
(string) --
retryStrategy (dict) --
The retry strategy to use for failed jobs that are submitted with this job definition.
attempts (integer) --
The number of times to move a job to the RUNNABLE status. You can specify between 1 and 10 attempts. If the value of attempts is greater than one, the job is retried on failure the same number of attempts as the value.
evaluateOnExit (list) --
Array of up to 5 objects that specify conditions under which the job should be retried or failed. If this parameter is specified, then the attempts parameter must also be specified.
(dict) --
Specifies a set of conditions to be met, and an action to take ( RETRY or EXIT ) if all conditions are met.
onStatusReason (string) --
Contains a glob pattern to match against the StatusReason returned for a job. The pattern can be up to 512 characters long, and can contain letters, numbers, periods (.), colons (:), and white space (including spaces or tabs). It can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.
onReason (string) --
Contains a glob pattern to match against the Reason returned for a job. The pattern can be up to 512 characters long, and can contain letters, numbers, periods (.), colons (:), and white space (including spaces and tabs). It can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.
onExitCode (string) --
Contains a glob pattern to match against the decimal representation of the ExitCode returned for a job. The pattern can be up to 512 characters long, can contain only numbers, and can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.

Specifies the action to take if all of the specified conditions ( onStatusReason , onReason , and onExitCode ) are met. The values aren't case sensitive.
containerProperties (dict) --
An object with various properties specific to container-based jobs.
image (string) --
The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with repository-url/image:tag . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.
Note
Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.
Images in Amazon ECR repositories use the full registry and repository URI (for example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name> ).
Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo ).
Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent ).
Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu ).
vcpus (integer) --
The number of vCPUs reserved for the job. Each vCPU is equivalent to 1,024 CPU shares. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. The number of vCPUs must be specified but can be be specified in several places. You must specify it at least once for each node.
This parameter is supported on EC2 resources but isn't supported for jobs that run on Fargate resources. For these resources, use resourceRequirement instead. You can use this parameter or resourceRequirements structure but not both.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided. For jobs that run on Fargate resources, you must specify the vCPU requirement for the job using resourceRequirements .
memory (integer) --
This parameter indicates the memory hard limit (in MiB) for a container. If your container attempts to exceed the specified number, it is terminated. You must specify at least 4 MiB of memory for a job using this parameter. The memory hard limit can be specified in several places. It must be specified for each node at least once.
This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.
This parameter is supported on EC2 resources but isn't supported on Fargate resources. For Fargate resources, you should specify the memory requirement using resourceRequirement . You can do this for EC2 resources.
Note
If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide .
command (list) --
The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd.
(string) --
jobRoleArn (string) --
The Amazon Resource Name (ARN) of the IAM role that the container can assume for AWS permissions. For more information, see IAM Roles for Tasks in the Amazon Elastic Container Service Developer Guide .
executionRoleArn (string) --
The Amazon Resource Name (ARN) of the execution role that AWS Batch can assume. For jobs that run on Fargate resources, you must provide an execution role. For more information, see AWS Batch execution IAM role in the AWS Batch User Guide .
volumes (list) --
A list of data volumes used in a job.
(dict) --
A data volume used in a job's container properties.
host (dict) --
The contents of the host parameter determine whether your data volume persists on the host container instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers associated with it stop running.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
sourcePath (string) --
The path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
Note
This parameter isn't applicable to jobs that run on Fargate resources and shouldn't be provided.
name (string) --
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints .
efsVolumeConfiguration (dict) --
This parameter is specified when you are using an Amazon Elastic File System file system for job storage. Jobs running on Fargate resources must specify a platformVersion of at least 1.4.0 .
fileSystemId (string) --
The Amazon EFS file system ID to use.
rootDirectory (string) --
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / which will enforce the path set on the Amazon EFS access point.
transitEncryption (string) --
Whether or not to enable encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be enabled if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide .
transitEncryptionPort (integer) --
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS Mount Helper in the Amazon Elastic File System User Guide .
authorizationConfig (dict) --
The authorization configuration details for the Amazon EFS file system.
accessPointId (string) --
The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which will enforce the path set on the EFS access point. If an access point is used, transit encryption must be enabled in the EFSVolumeConfiguration . For more information, see Working with Amazon EFS Access Points in the Amazon Elastic File System User Guide .
iam (string) --
Whether or not to use the AWS Batch execution IAM role defined in a job definition when mounting the Amazon EFS file system. If enabled, transit encryption must be enabled in the EFSVolumeConfiguration . If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS Access Points in the AWS Batch User Guide . EFS IAM authorization requires that TransitEncryption be ENABLED and that a JobRoleArn is specified.
environment (list) --
The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run.
Warning
We don't recommend using plaintext environment variables for sensitive information, such as credential data.
Note
Environment variables must not start with AWS_BATCH ; this naming convention is reserved for variables that are set by the AWS Batch service.

Note
GPUs are not available for jobs running on Fargate resources.
type="MEMORY"
The memory hard limit (in MiB) present to the container. This parameter is supported for jobs running on EC2 resources. If your container attempts to exceed the memory specified, the container is terminated. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.
Note
If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide .

Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
(dict) --
An object representing a container instance host device.
Note
This object isn't applicable to jobs running on Fargate resources and shouldn't be provided.

The explicit permissions to provide to the container for the device. By default, the container has permissions for read , write , and mknod for the device.
(string) --
initProcessEnabled (boolean) --
If true, run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log into your container instance and run the following command: sudo docker version | grep "Server API version"
sharedMemorySize (integer) --
The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
tmpfs (list) --
The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
(dict) --
The container path, mount options, and size of the tmpfs mount.

The absolute file path in the container where the tmpfs volume is mounted.
size (integer) --
The size (in MiB) of the tmpfs volume.
mountOptions (list) --
The list of tmpfs volume mount options.
Valid values: " defaults " | " ro " | " rw " | " suid " | " nosuid " | " dev " | " nodev " | " exec " | " noexec " | " sync " | " async " | " dirsync " | " remount " | " mand " | " nomand " | " atime " | " noatime " | " diratime " | " nodiratime " | " bind " | " rbind" | "unbindable" | "runbindable" | "private" | "rprivate" | "shared" | "rshared" | "slave" | "rslave" | "relatime " | " norelatime " | " strictatime " | " nostrictatime " | " mode " | " uid " | " gid " | " nr_inodes " | " nr_blocks " | " mpol "
(string) --
maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swapdetails in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
swappiness (integer) --
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping not to happen unless absolutely necessary. A swappiness value of 100 causes pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run.
Consider the following when you use a per-container swap configuration.
Swap space must be enabled and allocated on the container instance for the containers to use.
Note
The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
The swap space parameters are only supported for job definitions using EC2 resources.
If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60, and the total swap usage will be limited to two times the memory reservation of the container.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container might use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log into your container instance and run the following command: sudo docker version | grep "Server API version"
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .

maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swapdetails in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
swappiness (integer) --
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping not to happen unless absolutely necessary. A swappiness value of 100 causes pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run.
Consider the following when you use a per-container swap configuration.
Swap space must be enabled and allocated on the container instance for the containers to use.
Note
The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
The swap space parameters are only supported for job definitions using EC2 resources.
If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60, and the total swap usage will be limited to two times the memory reservation of the container.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container might use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log into your container instance and run the following command: sudo docker version | grep "Server API version"
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .

The path for the device on the host container instance.
containerPath (string) --
The path inside the container used to expose the host device. By default, the hostPath value is used.
permissions (list) --
The explicit permissions to provide to the container for the device. By default, the container has permissions for read , write , and mknod for the device.
(string) --
initProcessEnabled (boolean) --
If true, run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log into your container instance and run the following command: sudo docker version | grep "Server API version"

(string) --
maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swapdetails in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
swappiness (integer) --
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping not to happen unless absolutely necessary. A swappiness value of 100 causes pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run.
Consider the following when you use a per-container swap configuration.
Swap space must be enabled and allocated on the container instance for the containers to use.
Note
The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
The swap space parameters are only supported for job definitions using EC2 resources.
If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60, and the total swap usage will be limited to two times the memory reservation of the container.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However, the container might use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance. Or, alternatively, it must be configured on a different log server for remote logging options. For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers might be available in future releases of the Amazon ECS container agent.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log into your container instance and run the following command: sudo docker version | grep "Server API version"
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .

The size (in MiB) of the tmpfs volume.
mountOptions (list) --
The list of tmpfs volume mount options.
Valid values: " defaults " | " ro " | " rw " | " suid " | " nosuid " | " dev " | " nodev " | " exec " | " noexec " | " sync " | " async " | " dirsync " | " remount " | " mand " | " nomand " | " atime " | " noatime " | " diratime " | " nodiratime " | " bind " | " rbind" | "unbindable" | "runbindable" | "private" | "rprivate" | "shared" | "rshared" | "slave" | "rslave" | "relatime " | " norelatime " | " strictatime " | " nostrictatime " | " mode " | " uid " | " gid " | " nr_inodes " | " nr_blocks " | " mpol "
(string) --
maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swapdetails in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
swappiness (integer) --
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping not to happen unless absolutely necessary. A swappiness value of 100 causes pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run.
Consider the following when you use a per-container swap configuration.
Swap space must be enabled and allocated on the container instance for the containers to use.
Note
The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
The swap space parameters are only supported for job definitions using EC2 resources.
If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60, and the total swap usage will be limited to two times the memory reservation of the container.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container might use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log into your container instance and run the following command: sudo docker version | grep "Server API version"
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
logDriver (string) --
The log driver to use for the container. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.
The supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , and splunk .
Note
Jobs running on Fargate resources are restricted to the awslogs and splunk log drivers.
awslogs
Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs Log Driver in the AWS Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.
fluentd
Specifies the Fluentd logging driver. For more information, including usage and options, see Fluentd logging driver in the Docker documentation.
gelf
Specifies the Graylog Extended Format (GELF) logging driver. For more information, including usage and options, see Graylog Extended Format logging driver in the Docker documentation.
journald
Specifies the journald logging driver. For more information, including usage and options, see Journald logging driver in the Docker documentation.
json-file
Specifies the JSON file logging driver. For more information, including usage and options, see JSON File logging driver in the Docker documentation.
splunk
Specifies the Splunk logging driver. For more information, including usage and options, see Splunk logging driver in the Docker documentation.
syslog
Specifies the syslog logging driver. For more information, including usage and options, see Syslog logging driver in the Docker documentation.
Note
If you have a custom driver that's not listed earlier that you want to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log into your container instance and run the following command: sudo docker version | grep "Server API version"
options (dict) --
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote API or greater on your container instance.

networkConfiguration (dict) --
The network configuration for jobs running on Fargate resources. Jobs running on EC2 resources must not specify this parameter.
assignPublicIp (string) --
Indicates whether the job should have a public IP address. For a job running on Fargate resources in a private subnet to send outbound traffic to the internet (for example, in order to pull container images), the private subnet requires a NAT gateway be attached to route requests to the internet. For more information, see Amazon ECS task networking. The default value is "DISABLED".
fargatePlatformConfiguration (dict) --
The platform configuration for jobs running on Fargate resources. Jobs running on EC2 resources must not specify this parameter.
platformVersion (string) --
The AWS Fargate platform version where the jobs are running. A platform version is specified only for jobs running on Fargate resources. If one isn't specified, the LATEST platform version is used by default. This uses a recent, approved version of the AWS Fargate platform for compute resources. For more information, see AWS Fargate platform versions in the Amazon Elastic Container Service Developer Guide .
arrayProperties (dict) --

string
[REQUIRED]
The name of the job definition to register. Up to 128 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.
string
[REQUIRED]
The type of job definition. For more information about multi-node parallel jobs, see Creating a multi-node parallel job definition in the AWS Batch User Guide .
Note
If the job is run on Fargate resources, then multinode isn't supported.
dict
Default parameter substitution placeholders to set in the job definition. Parameters are specified as a key-value pair mapping. Parameters in a SubmitJob request override any corresponding parameter defaults from the job definition.
(string) --
(string) --
dict
An object with various properties specific to single-node container-based jobs. If the job definition's type parameter is container , then you must specify either containerProperties or nodeProperties .
Note
If the job runs on Fargate resources, then you must not specify nodeProperties ; use only containerProperties .
image (string) --
The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with repository-url/image:tag . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.
Note
Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.
Images in Amazon ECR repositories use the full registry and repository URI (for example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name> ).
Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo ).
Images in other repositories on Docker Hub are qualified with an organization name (for example, amazon/amazon-ecs-agent ).
Images in other online repositories are qualified further by a domain name (for example, quay.io/assemblyline/ubuntu ).
vcpus (integer) --
The number of vCPUs reserved for the job. Each vCPU is equivalent to 1,024 CPU shares. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option to docker run. The number of vCPUs must be specified but can be be specified in several places. You must specify it at least once for each node.
This parameter is supported on EC2 resources but isn't supported for jobs that run on Fargate resources. For these resources, use resourceRequirement instead. You can use this parameter or resourceRequirements structure but not both.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided. For jobs that run on Fargate resources, you must specify the vCPU requirement for the job using resourceRequirements .
memory (integer) --
This parameter indicates the memory hard limit (in MiB) for a container. If your container attempts to exceed the specified number, it is terminated. You must specify at least 4 MiB of memory for a job using this parameter. The memory hard limit can be specified in several places. It must be specified for each node at least once.
This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.
This parameter is supported on EC2 resources but isn't supported on Fargate resources. For Fargate resources, you should specify the memory requirement using resourceRequirement . You can do this for EC2 resources.
Note
If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory Management in the AWS Batch User Guide .
command (list) --
The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd.

volumes (list) --
A list of data volumes used in a job.
(dict) --
A data volume used in a job's container properties.
host (dict) --
The contents of the host parameter determine whether your data volume persists on the host container instance and where it is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers associated with it stop running.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
sourcePath (string) --
The path on the host container instance that's presented to the container. If this parameter is empty, then the Docker daemon has assigned a host path for you. If this parameter contains a file location, then the data volume persists at the specified location on the host container instance until you delete it manually. If the source path location doesn't exist on the host container instance, the Docker daemon creates it. If the location does exist, the contents of the source path folder are exported.
Note
This parameter isn't applicable to jobs that run on Fargate resources and shouldn't be provided.
name (string) --
The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. This name is referenced in the sourceVolume parameter of container definition mountPoints .
efsVolumeConfiguration (dict) --
This parameter is specified when you are using an Amazon Elastic File System file system for job storage. Jobs running on Fargate resources must specify a platformVersion of at least 1.4.0 .
fileSystemId (string) -- [REQUIRED]
The Amazon EFS file system ID to use.
rootDirectory (string) --
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter is omitted, the root of the Amazon EFS volume will be used. Specifying / will have the same effect as omitting this parameter.
Warning
If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / which will enforce the path set on the Amazon EFS access point.
transitEncryption (string) --
Whether or not to enable encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon EFS server. Transit encryption must be enabled if Amazon EFS IAM authorization is used. If this parameter is omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the Amazon Elastic File System User Guide .
transitEncryptionPort (integer) --
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you do not specify a transit encryption port, it will use the port selection strategy that the Amazon EFS mount helper uses. For more information, see EFS Mount Helper in the Amazon Elastic File System User Guide .
authorizationConfig (dict) --
The authorization configuration details for the Amazon EFS file system.
accessPointId (string) --
The Amazon EFS access point ID to use. If an access point is specified, the root directory value specified in the EFSVolumeConfiguration must either be omitted or set to / which will enforce the path set on the EFS access point. If an access point is used, transit encryption must be enabled in the EFSVolumeConfiguration . For more information, see Working with Amazon EFS Access Points in the Amazon Elastic File System User Guide .
iam (string) --
Whether or not to use the AWS Batch execution IAM role defined in a job definition when mounting the Amazon EFS file system. If enabled, transit encryption must be enabled in the EFSVolumeConfiguration . If this parameter is omitted, the default value of DISABLED is used. For more information, see Using Amazon EFS Access Points in the AWS Batch User Guide . EFS IAM authorization requires that TransitEncryption be ENABLED and that a JobRoleArn is specified.
environment (list) --
The environment variables to pass to a container. This parameter maps to Env in the Create a container section of the Docker Remote API and the --env option to docker run.
Warning
We don't recommend using plaintext environment variables for sensitive information, such as credential data.
Note
Environment variables must not start with AWS_BATCH ; this naming convention is reserved for variables that are set by the AWS Batch service.

If this value is true , the container has read-only access to the volume. Otherwise, the container can write to the volume. The default value is false .
sourceVolume (string) --
The name of the volume to mount.
readonlyRootFilesystem (boolean) --
When this parameter is true, the container is given read-only access to its root file system. This parameter maps to ReadonlyRootfs in the Create a container section of the Docker Remote API and the --read-only option to docker run .
privileged (boolean) --
When this parameter is true, the container is given elevated permissions on the host container instance (similar to the root user). This parameter maps to Privileged in the Create a container section of the Docker Remote API and the --privileged option to docker run. The default value is false.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided, or specified as false.
ulimits (list) --

(string) --
initProcessEnabled (boolean) --
If true, run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log into your container instance and run the following command: sudo docker version | grep "Server API version"

(string) --
maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swapdetails in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
swappiness (integer) --
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping not to happen unless absolutely necessary. A swappiness value of 100 causes pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run.
Consider the following when you use a per-container swap configuration.
Swap space must be enabled and allocated on the container instance for the containers to use.
Note
The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
The swap space parameters are only supported for job definitions using EC2 resources.
If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60, and the total swap usage will be limited to two times the memory reservation of the container.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container might use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log into your container instance and run the following command: sudo docker version | grep "Server API version"
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .

You can nest node ranges, for example 0:10 and 4:5 , in which case the 4:5 range properties override the 0:10 properties.
container (dict) --
The container details for the node range.
image (string) --
The image used to start a container. This string is passed directly to the Docker daemon. Images in the Docker Hub registry are available by default. Other repositories are specified with repository-url/image:tag . Up to 255 letters (uppercase and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed. This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.
Note
Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.
Images in Amazon ECR repositories use the full registry and repository URI (for example, 012345678910.dkr.ecr.<region-name>.amazonaws.com/<repository-name> ).
Images in official repositories on Docker Hub use a single name (for example, ubuntu or mongo ).

The explicit permissions to provide to the container for the device. By default, the container has permissions for read , write , and mknod for the device.
(string) --
initProcessEnabled (boolean) --
If true, run an init process inside the container that forwards signals and reaps processes. This parameter maps to the --init option to docker run. This parameter requires version 1.25 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log into your container instance and run the following command: sudo docker version | grep "Server API version"
sharedMemorySize (integer) --
The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
tmpfs (list) --
The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
(dict) --
The container path, mount options, and size of the tmpfs mount.
Note
This object isn't applicable to jobs running on Fargate resources.
containerPath (string) -- [REQUIRED]
The absolute file path in the container where the tmpfs volume is mounted.
size (integer) -- [REQUIRED]
The size (in MiB) of the tmpfs volume.
mountOptions (list) --
The list of tmpfs volume mount options.
Valid values: " defaults " | " ro " | " rw " | " suid " | " nosuid " | " dev " | " nodev " | " exec " | " noexec " | " sync " | " async " | " dirsync " | " remount " | " mand " | " nomand " | " atime " | " noatime " | " diratime " | " nodiratime " | " bind " | " rbind" | "unbindable" | "runbindable" | "private" | "rprivate" | "shared" | "rshared" | "slave" | "rslave" | "relatime " | " norelatime " | " strictatime " | " nostrictatime " | " mode " | " uid " | " gid " | " nr_inodes " | " nr_blocks " | " mpol "
(string) --
maxSwap (integer) --
The total amount of swap memory (in MiB) a container can use. This parameter is translated to the --memory-swap option to docker run where the value is the sum of the container memory plus the maxSwap value. For more information, see --memory-swapdetails in the Docker documentation.
If a maxSwap value of 0 is specified, the container doesn't use swap. Accepted values are 0 or any positive integer. If the maxSwap parameter is omitted, the container doesn't use the swap configuration for the container instance it is running on. A maxSwap value must be set for the swappiness parameter to be used.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
swappiness (integer) --
This allows you to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping not to happen unless absolutely necessary. A swappiness value of 100 causes pages to be swapped very aggressively. Accepted values are whole numbers between 0 and 100 . If the swappiness parameter isn't specified, a default value of 60 is used. If a value isn't specified for maxSwap then this parameter is ignored. If maxSwap is set to 0, the container doesn't use swap. This parameter maps to the --memory-swappiness option to docker run.
Consider the following when you use a per-container swap configuration.
Swap space must be enabled and allocated on the container instance for the containers to use.
Note
The Amazon ECS optimized AMIs don't have swap enabled by default. You must enable swap on the instance to use this feature. For more information, see Instance Store Swap Volumes in the Amazon EC2 User Guide for Linux Instances or How do I allocate memory to work as swap space in an Amazon EC2 instance by using a swap file?
The swap space parameters are only supported for job definitions using EC2 resources.
If the maxSwap and swappiness parameters are omitted from a job definition, each container will have a default swappiness value of 60, and the total swap usage will be limited to two times the memory reservation of the container.
Note
This parameter isn't applicable to jobs running on Fargate resources and shouldn't be provided.
logConfiguration (dict) --
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option to docker run. By default, containers use the same logging driver that the Docker daemon uses. However the container might use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information on the options for different supported log drivers, see Configure logging drivers in the Docker documentation.
Note
AWS Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log into your container instance and run the following command: sudo docker version | grep "Server API version"
Note
The Amazon ECS container agent running on a container instance must register the logging drivers available on that instance with the ECS_AVAILABLE_LOGGING_DRIVERS environment variable before containers placed on that instance can use these log configuration options. For more information, see Amazon ECS Container Agent Configuration in the Amazon Elastic Container Service Developer Guide .
logDriver (string) -- [REQUIRED]
The log driver to use for the container. The valid values listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.
The supported log drivers are awslogs , fluentd , gelf , json-file , journald , logentries , syslog , and splunk .
Note
Jobs running on Fargate resources are restricted to the awslogs and splunk log drivers.
awslogs
Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs Log Driver in the AWS Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.
fluentd
Specifies the Fluentd logging driver. For more information, including usage and options, see Fluentd logging driver in the Docker documentation.
gelf
Specifies the Graylog Extended Format (GELF) logging driver. For more information, including usage and options, see Graylog Extended Format logging driver in the Docker documentation.
journald
Specifies the journald logging driver. For more information, including usage and options, see Journald logging driver in the Docker documentation.
json-file
Specifies the JSON file logging driver. For more information, including usage and options, see JSON File logging driver in the Docker documentation.

Contains a glob pattern to match against the Reason returned for a job. The pattern can be up to 512 characters long, and can contain letters, numbers, periods (.), colons (:), and white space (including spaces and tabs). It can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.
onExitCode (string) --
Contains a glob pattern to match against the decimal representation of the ExitCode returned for a job. The pattern can be up to 512 characters long, can contain only numbers, and can optionally end with an asterisk (*) so that only the start of the string needs to be an exact match.
action (string) -- [REQUIRED]
Specifies the action to take if all of the specified conditions ( onStatusReason , onReason , and onExitCode ) are met. The values aren't case sensitive.
boolean
Specifies whether to propagate the tags from the job or job definition to the corresponding Amazon ECS task. If no value is specified, the tags are not propagated. Tags can only be propagated to the tasks during task creation. For tags with the same name, job tags are given priority over job definitions tags. If the total number of combined tags from the job and job definition is over 50, the job is moved to the FAILED state.
dict
The timeout configuration for jobs that are submitted with this job definition, after which AWS Batch terminates your jobs if they have not finished. If a job is terminated due to a timeout, it isn't retried. The minimum value for the timeout is 60 seconds.
