Options

--job-definition-name (string)

The name of the job definition to register. It can be up to 128 letters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).

--type (string)

The type of job definition. For more information about multi-node parallel jobs, see Creating a multi-node parallel job definition in the Batch User Guide .

Note

If the job is run on Fargate resources, then multinode isn’t supported.

Possible values:

• container

• multinode

--parameters (map)

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.

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--scheduling-priority (integer)

The scheduling priority for jobs that are submitted with this job definition. This will only affect jobs in job queues with a fair share policy. Jobs with a higher scheduling priority will be scheduled before jobs with a lower scheduling priority.

The minimum supported value is 0 and the maximum supported value is 9999.

--container-properties (structure)

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)

This parameter is deprecated, use resourceRequirements to specify the vCPU requirements for the job definition. It’s not supported for jobs that run on Fargate resources. For jobs run on EC2 resources, it specifies 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 specified in several places. You must specify it at least once for each node.

memory -> (integer)

This parameter is deprecated, use resourceRequirements to specify the memory requirements for the job definition. It’s not supported for jobs that run on Fargate resources. For jobs run on EC2 resources, it specifies the memory hard limit (in MiB) for a container. If your container attempts to exceed the specified number, it’s 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.

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 Amazon Web Services 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 Batch can assume. For jobs that run on Fargate resources, you must provide an execution role. For more information, see Batch execution IAM role in the Batch User Guide .

volumes -> (list)

A list of data volumes used in a job.

(structure)

A data volume used in a job’s container properties.

host -> (structure)

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 that are 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. It can be up to 255 letters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_). This name is referenced in the sourceVolume parameter of container definition mountPoints .

efsVolumeConfiguration -> (structure)

This parameter is specified when you are using an Amazon Elastic File System file system for job storage. Jobs that are 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 is used instead. Specifying / has the same effect as omitting this parameter. The maximum length is 4,096 characters.

Warning

If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / , which enforces the path set on the Amazon EFS access point.

transitEncryption -> (string)

Determines whether 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 don’t specify a transit encryption port, it uses the port selection strategy that the Amazon EFS mount helper uses. The value must be between 0 and 65,535. For more information, see EFS Mount Helper in the Amazon Elastic File System User Guide .

authorizationConfig -> (structure)

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 Batch job 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 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 Batch service.

(structure)

A key-value pair object.

name -> (string)

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 that are running on Fargate resources and shouldn’t be provided, or specified as false.

ulimits -> (list)

A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run .

Note

GPUs are not available for jobs that are running on Fargate resources.

type=”MEMORY”

The memory hard limit (in MiB) present to the container. This parameter is supported for jobs that are 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 Batch User Guide .

Linux-specific modifications that are applied to the container, such as details for device mappings.

devices -> (list)

Any host devices to expose to the container. This parameter maps to Devices in the Create a container section of the Docker Remote API and the --device option to docker run .

Note

This parameter isn’t applicable to jobs that are running on Fargate resources and shouldn’t be provided.

(structure)

An object representing a container instance host device.

Note

This object isn’t applicable to jobs that are running on Fargate resources and shouldn’t be provided.

hostPath -> (string)

The path for the device on the host container instance.

containerPath -> (string)

The path inside the container that’s 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"

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 that are 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 that are running on Fargate resources and shouldn’t be provided.

(structure)

The container path, mount options, and size of the tmpfs mount.

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-swap details <https://docs.docker.com/config/containers/resource_constraints/#–memory-swap-details>`__ 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 that are 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 that are running on Fargate resources and shouldn’t be provided.

logConfiguration -> (structure)

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

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 that are 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 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 -> (map)

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.

key -> (string)

value -> (string)

secretOptions -> (list)

The secrets to pass to the log configuration. For more information, see Specifying Sensitive Data in the Batch User Guide .

(structure)

An object representing the secret to expose to your container. Secrets can be exposed to a container in the following ways:

• To inject sensitive data into your containers as environment variables, use the secrets container definition parameter.

• To reference sensitive information in the log configuration of a container, use the secretOptions container definition parameter.

For more information, see Specifying sensitive data in the Batch User Guide .

name -> (string)

For a job that is running on Fargate resources in a private subnet to send outbound traffic to the internet (for example, 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 -> (structure)

The platform configuration for jobs that are running on Fargate resources. Jobs that are running on EC2 resources must not specify this parameter.

platformVersion -> (string)

The Fargate platform version where the jobs are running. A platform version is specified only for jobs that are 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 Fargate platform for compute resources.

--node-properties (structure)

An object with various properties specific to multi-node parallel jobs. If you specify node properties for a job, it becomes a multi-node parallel job. For more information, see Multi-node Parallel Jobs in the Batch User Guide . 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 containerProperties instead.

numNodes -> (integer)

The number of nodes associated with a multi-node parallel job.

mainNode -> (integer)

Specifies the node index for the main node of a multi-node parallel job. This node index value must be fewer than the number of nodes.

nodeRangeProperties -> (list)

A list of node ranges and their properties associated with a multi-node parallel job.

(structure)

An object representing the properties of the node range for a multi-node parallel job.

targetNodes -> (string)

The range of nodes, using node index values. A range of 0:3 indicates nodes with index values of 0 through 3 . If the starting range value is omitted (:n ), then 0 is used to start the range. If the ending range value is omitted (n: ), then the highest possible node index is used to end the range. Your accumulative node ranges must account for all nodes (0:n ). 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 -> (structure)

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 ).

• 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)

This parameter is deprecated, use resourceRequirements to specify the vCPU requirements for the job definition. It’s not supported for jobs that run on Fargate resources. For jobs run on EC2 resources, it specifies 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 specified in several places. You must specify it at least once for each node.

memory -> (integer)

This parameter is deprecated, use resourceRequirements to specify the memory requirements for the job definition. It’s not supported for jobs that run on Fargate resources. For jobs run on EC2 resources, it specifies the memory hard limit (in MiB) for a container. If your container attempts to exceed the specified number, it’s 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.

command -> (list)

A list of data volumes used in a job.

(structure)

A data volume used in a job’s container properties.

host -> (structure)

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 that are 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. It can be up to 255 letters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_). This name is referenced in the sourceVolume parameter of container definition mountPoints .

This parameter is specified when you are using an Amazon Elastic File System file system for job storage. Jobs that are 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 is used instead. Specifying / has the same effect as omitting this parameter. The maximum length is 4,096 characters.

Warning

If an EFS access point is specified in the authorizationConfig , the root directory parameter must either be omitted or set to / , which enforces the path set on the Amazon EFS access point.

transitEncryption -> (string)

Determines whether 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 don’t specify a transit encryption port, it uses the port selection strategy that the Amazon EFS mount helper uses. The value must be between 0 and 65,535. For more information, see EFS Mount Helper in the Amazon Elastic File System User Guide .

authorizationConfig -> (structure)

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 Batch job 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 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.

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 Batch User Guide .

(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 .

(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-swap details <https://docs.docker.com/config/containers/resource_constraints/#–memory-swap-details>`__ 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 that are 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 that are running on Fargate resources and shouldn’t be provided.

logConfiguration -> (structure)

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

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 that are 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 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

--retry-strategy (structure)

The retry strategy to use for failed jobs that are submitted with this job definition. Any retry strategy that’s specified during a SubmitJob operation overrides the retry strategy defined here. If a job is terminated due to a timeout, it isn’t retried.

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.

(structure)

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 in length. It 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.

The string can be between 1 and 512 characters in length.

onReason -> (string)

Contains a glob pattern to match against the Reason returned for a job. The pattern can be up to 512 characters in length. It 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.

The string can be between 1 and 512 characters in length.

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 in length. It 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.

The string can be between 1 and 512 characters in length.

action -> (string)

Specifies the action to take if all of the specified conditions (onStatusReason , onReason , and onExitCode ) are met. The values aren’t case sensitive.

Shorthand Syntax:

attempts=integer,evaluateOnExit=[{onStatusReason=string,onReason=string,onExitCode=string,action=string},{onStatusReason=string,onReason=string,onExitCode=string,action=string}]

JSON Syntax:

{
  "attempts": integer,
  "evaluateOnExit": [
    {
      "onStatusReason": "string",
      "onReason": "string",
      "onExitCode": "string",
      "action": "RETRY"|"EXIT"
    }
    ...
  ]
}

--propagate-tags | --no-propagate-tags (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.

--timeout (structure)

The timeout configuration for jobs that are submitted with this job definition, after which 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. Any timeout configuration that’s specified during a SubmitJob operation overrides the timeout configuration defined here. For more information, see Job Timeouts in the Batch User Guide .

attemptDurationSeconds -> (integer)

The time duration in seconds (measured from the job attempt’s startedAt timestamp) after which Batch terminates your jobs if they have not finished. The minimum value for the timeout is 60 seconds.

Shorthand Syntax:

attemptDurationSeconds=integer

JSON Syntax:

{
  "attemptDurationSeconds": integer
}

--tags (map)

The tags that you apply to the job definition to help you categorize and organize your resources. Each tag consists of a key and an optional value. For more information, see Tagging Amazon Web Services Resources in Batch User Guide .

key -> (string)

value -> (string)

Shorthand Syntax:

KeyName1=string,KeyName2=string

JSON Syntax:

{"string": "string"
  ...}

--platform-capabilities (list)

The platform capabilities required by the job definition. If no value is specified, it defaults to EC2 . To run the job on Fargate resources, specify FARGATE .

(string)

Syntax:

"string" "string" ...

Where valid values are:
  EC2
  FARGATE

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples

To register a job definition

This example registers a job definition for a simple container job.

Command:

aws batch register-job-definition --job-definition-name sleep30 --type container --container-properties '{ "image": "busybox", "vcpus": 1, "memory": 128, "command": [ "sleep", "30"]}'

Output:

{
    "jobDefinitionArn": "arn:aws:batch:us-east-1:012345678910:job-definition/sleep30:1",
    "jobDefinitionName": "sleep30",
    "revision": 1
}

Output

jobDefinitionName -> (string)

The name of the job definition.

jobDefinitionArn -> (string)

The Amazon Resource Name (ARN) of the job definition.

revision -> (integer)

The revision of the job definition.
