Client: Aws\Batch\BatchClient
Service ID: batch
Version: 2016-08-10

This page describes the parameters and results for the operations of the AWS Batch (2016-08-10), and shows how to use the Aws\Batch\BatchClient object to call the described operations. This documentation is specific to the 2016-08-10 API version of the service.

Operation Summary

Each of the following operations can be created from a client using $client->getCommand('CommandName'), where "CommandName" is the name of one of the following operations. Note: a command is a value that encapsulates an operation and the parameters used to create an HTTP request.

You can also create and send a command immediately using the magic methods available on a client object: $client->commandName(/* parameters */). You can send the command asynchronously (returning a promise) by appending the word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

Paginators

Paginators handle automatically iterating over paginated API results. Paginators are associated with specific API operations, and they accept the parameters that the corresponding API operation accepts. You can get a paginator from a client class using getPaginator($paginatorName, $operationParameters). This client supports the following paginators:

DescribeComputeEnvironments
DescribeJobDefinitions
DescribeJobQueues
ListJobs
ListSchedulingPolicies

Operations

CancelJob

$result = $client->cancelJob([/* ... */]);
$promise = $client->cancelJobAsync([/* ... */]);

Cancels a job in an Batch job queue. Jobs that are in a SUBMITTED, PENDING, or RUNNABLE state are cancelled and the job status is updated to FAILED.

A PENDING job is canceled after all dependency jobs are completed. Therefore, it may take longer than expected to cancel a job in PENDING status.

When you try to cancel an array parent job in PENDING, Batch attempts to cancel all child jobs. The array parent job is canceled when all child jobs are completed.

Jobs that progressed to the STARTING or RUNNING state aren't canceled. However, the API operation still succeeds, even if no job is canceled. These jobs must be terminated with the TerminateJob operation.

Parameter Syntax

$result = $client->cancelJob([
    'jobId' => '<string>', // REQUIRED
    'reason' => '<string>', // REQUIRED
]);

Parameter Details

Members
jobId
Required: Yes
Type: string

The Batch job ID of the job to cancel.

reason
Required: Yes
Type: string

A message to attach to the job that explains the reason for canceling it. This message is returned by future DescribeJobs operations on the job. This message is also recorded in the Batch activity logs.

Result Syntax

[]

Result Details

The results for this operation are always empty.

Errors

ClientException:

These errors are usually caused by a client action. One example cause is using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Another cause is specifying an identifier that's not valid.

ServerException:

These errors are usually caused by a server issue.

Examples

Example 1: To cancel a job

$result = $client->cancelJob([
    'jobId' => '1d828f65-7a4d-42e8-996d-3b900ed59dc4',
    'reason' => 'Cancelling job.',
]);

CreateComputeEnvironment

$result = $client->createComputeEnvironment([/* ... */]);
$promise = $client->createComputeEnvironmentAsync([/* ... */]);

Creates an Batch compute environment. You can create MANAGED or UNMANAGED compute environments. MANAGED compute environments can use Amazon EC2 or Fargate resources. UNMANAGED compute environments can only use EC2 resources.

In a managed compute environment, Batch manages the capacity and instance types of the compute resources within the environment. This is based on the compute resource specification that you define or the launch template that you specify when you create the compute environment. Either, you can choose to use EC2 On-Demand Instances and EC2 Spot Instances. Or, you can use Fargate and Fargate Spot capacity in your managed compute environment. You can optionally set a maximum price so that Spot Instances only launch when the Spot Instance price is less than a specified percentage of the On-Demand price.

Multi-node parallel jobs aren't supported on Spot Instances.

In an unmanaged compute environment, you can manage your own EC2 compute resources and have flexibility with how you configure your compute resources. For example, you can use custom AMIs. However, you must verify that each of your AMIs meet the Amazon ECS container instance AMI specification. For more information, see container instance AMIs in the Amazon Elastic Container Service Developer Guide. After you created your unmanaged compute environment, you can use the DescribeComputeEnvironments operation to find the Amazon ECS cluster that's associated with it. Then, launch your container instances into that Amazon ECS cluster. For more information, see Launching an Amazon ECS container instance in the Amazon Elastic Container Service Developer Guide.

To create a compute environment that uses EKS resources, the caller must have permissions to call eks:DescribeCluster.

Batch doesn't automatically upgrade the AMIs in a compute environment after it's created. For example, it also doesn't update the AMIs in your compute environment when a newer version of the Amazon ECS optimized AMI is available. You're responsible for the management of the guest operating system. This includes any updates and security patches. You're also responsible for any additional application software or utilities that you install on the compute resources. There are two ways to use a new AMI for your Batch jobs. The original method is to complete these steps:

  1. Create a new compute environment with the new AMI.

  2. Add the compute environment to an existing job queue.

  3. Remove the earlier compute environment from your job queue.

  4. Delete the earlier compute environment.

In April 2022, Batch added enhanced support for updating compute environments. For more information, see Updating compute environments. To use the enhanced updating of compute environments to update AMIs, follow these rules:

  • Either don't set the service role (serviceRole) parameter or set it to the AWSBatchServiceRole service-linked role.

  • Set the allocation strategy (allocationStrategy) parameter to BEST_FIT_PROGRESSIVE, SPOT_CAPACITY_OPTIMIZED, or SPOT_PRICE_CAPACITY_OPTIMIZED.

  • Set the update to latest image version (updateToLatestImageVersion) parameter to true. The updateToLatestImageVersion parameter is used when you update a compute environment. This parameter is ignored when you create a compute environment.

  • Don't specify an AMI ID in imageId, imageIdOverride (in ec2Configuration ), or in the launch template (launchTemplate). In that case, Batch selects the latest Amazon ECS optimized AMI that's supported by Batch at the time the infrastructure update is initiated. Alternatively, you can specify the AMI ID in the imageId or imageIdOverride parameters, or the launch template identified by the LaunchTemplate properties. Changing any of these properties starts an infrastructure update. If the AMI ID is specified in the launch template, it can't be replaced by specifying an AMI ID in either the imageId or imageIdOverride parameters. It can only be replaced by specifying a different launch template, or if the launch template version is set to $Default or $Latest, by setting either a new default version for the launch template (if $Default) or by adding a new version to the launch template (if $Latest).

If these rules are followed, any update that starts an infrastructure update causes the AMI ID to be re-selected. If the version setting in the launch template (launchTemplate) is set to $Latest or $Default, the latest or default version of the launch template is evaluated up at the time of the infrastructure update, even if the launchTemplate wasn't updated.

]);

Parameter Details

Members
computeEnvironmentName
Required: Yes
Type: string

The name for your compute environment. It can be up to 128 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).

computeResources
Type: ComputeResource structure

Details about the compute resources managed by the compute environment. This parameter is required for managed compute environments. For more information, see Compute Environments in the Batch User Guide.

context
Type: string

Reserved.

eksConfiguration
Type: EksConfiguration structure

The details for the Amazon EKS cluster that supports the compute environment.

serviceRole
Type: string

The full Amazon Resource Name (ARN) of the IAM role that allows Batch to make calls to other Amazon Web Services services on your behalf. For more information, see Batch service IAM role in the Batch User Guide.

If your account already created the Batch service-linked role, that role is used by default for your compute environment unless you specify a different role here. If the Batch service-linked role doesn't exist in your account, and no role is specified here, the service attempts to create the Batch service-linked role in your account.

If your specified role has a path other than /, then you must specify either the full role ARN (recommended) or prefix the role name with the path. For example, if a role with the name bar has a path of /foo/, specify /foo/bar as the role name. For more information, see Friendly names and paths in the IAM User Guide.

Depending on how you created your Batch service role, its ARN might contain the service-role path prefix. When you only specify the name of the service role, Batch assumes that your ARN doesn't use the service-role path prefix. Because of this, we recommend that you specify the full ARN of your service role when you create compute environments.

state
Type: string

The state of the compute environment. If the state is ENABLED, then the compute environment accepts jobs from a queue and can scale out automatically based on queues.

If the state is ENABLED, then the Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically, based on the job queue demand.

If the state is DISABLED, then the Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out.

Compute environments in a DISABLED state may continue to incur billing charges. To prevent additional charges, turn off and then delete the compute environment. For more information, see State in the Batch User Guide.

When an instance is idle, the instance scales down to the minvCpus value. However, the instance size doesn't change. For example, consider a c5.8xlarge instance with a minvCpus value of 4 and a desiredvCpus value of 36. This instance doesn't scale down to a c5.large instance.

tags
Type: Associative array of custom strings keys (TagKey) to strings

The tags that you apply to the compute environment 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 Amazon Web Services General Reference.

These tags can be updated or removed using the TagResource and UntagResource API operations. These tags don't propagate to the underlying compute resources.

type
Required: Yes
Type: string

The type of the compute environment: MANAGED or UNMANAGED. For more information, see Compute Environments in the Batch User Guide.

unmanagedvCpus
Type: int

The maximum number of vCPUs for an unmanaged compute environment. This parameter is only used for fair share scheduling to reserve vCPU capacity for new share identifiers. If this parameter isn't provided for a fair share job queue, no vCPU capacity is reserved.

This parameter is only supported when the type parameter is set to UNMANAGED.

CreateJobQueue

$result = $client->createJobQueue([/* ... */]);
$promise = $client->createJobQueueAsync([/* ... */]);

Creates an Batch job queue. When you create a job queue, you associate one or more compute environments to the queue and assign an order of preference for the compute environments.

You also set a priority to the job queue that determines the order that the Batch scheduler places jobs onto its associated compute environments. For example, if a compute environment is associated with more than one job queue, the job queue with a higher priority is given preference for scheduling jobs to that compute environment.

Parameter Syntax

$result = $client->createJobQueue([
    'computeEnvironmentOrder' => [ // REQUIRED
        [
            'computeEnvironment' => '<string>', // REQUIRED
            'order' => <integer>, // REQUIRED

]);

Parameter Details

Members
computeEnvironmentOrder
Required: Yes
Type: Array of ComputeEnvironmentOrder structures

The set of compute environments mapped to a job queue and their order relative to each other. The job scheduler uses this parameter to determine which compute environment runs a specific job. Compute environments must be in the VALID state before you can associate them with a job queue. You can associate up to three compute environments with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT); EC2 and Fargate compute environments can't be mixed.

All compute environments that are associated with a job queue must share the same architecture. Batch doesn't support mixing compute environment architecture types in a single job queue.

jobQueueName
Required: Yes
Type: string

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

jobStateTimeLimitActions
Type: Array of JobStateTimeLimitAction structures

The set of actions that Batch performs on jobs that remain at the head of the job queue in the specified state longer than specified times. Batch will perform each action after maxTimeSeconds has passed.

priority
Required: Yes
Type: int

The priority of the job queue. Job queues with a higher priority (or a higher integer value for the priority parameter) are evaluated first when associated with the same compute environment. Priority is determined in descending order. For example, a job queue with a priority value of 10 is given scheduling preference over a job queue with a priority value of 1. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT); EC2 and Fargate compute environments can't be mixed.

schedulingPolicyArn
Type: string

The Amazon Resource Name (ARN) of the fair share scheduling policy. If this parameter is specified, the job queue uses a fair share scheduling policy. If this parameter isn't specified, the job queue uses a first in, first out (FIFO) scheduling policy. After a job queue is created, you can replace but can't remove the fair share scheduling policy. The format is aws:Partition:batch:Region:Account:scheduling-policy/Name . An example is aws:aws:batch:us-west-2:123456789012:scheduling-policy/MySchedulingPolicy.

state
Type: string

The state of the job queue. If the job queue state is ENABLED, it is able to accept jobs. If the job queue state is DISABLED, new jobs can't be added to the queue, but jobs already in the queue can finish.

tags
Type: Associative array of custom strings keys (TagKey) to strings

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

These errors are usually caused by a client action. One example cause is using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Another cause is specifying an identifier that's not valid.

ServerException:

These errors are usually caused by a server issue.

DeleteComputeEnvironment

$result = $client->deleteComputeEnvironment([/* ... */]);
$promise = $client->deleteComputeEnvironmentAsync([/* ... */]);

Deletes an Batch compute environment.

Before you can delete a compute environment, you must set its state to DISABLED with the UpdateComputeEnvironment API operation and disassociate it from any job queues with the UpdateJobQueue API operation. Compute environments that use Fargate resources must terminate all active jobs on that compute environment before deleting the compute environment. If this isn't done, the compute environment enters an invalid state.

Parameter Syntax

$result = $client->deleteComputeEnvironment([
    'computeEnvironment' => '<string>', // REQUIRED
]);

Parameter Details

Members
computeEnvironment
Required: Yes
Type: string

The name or Amazon Resource Name (ARN) of the compute environment to delete.

DeleteJobQueue

$result = $client->deleteJobQueue([/* ... */]);
$promise = $client->deleteJobQueueAsync([/* ... */]);

Deletes the specified job queue. You must first disable submissions for a queue with the UpdateJobQueue operation. All jobs in the queue are eventually terminated when you delete a job queue. The jobs are terminated at a rate of about 16 jobs each second.

It's not necessary to disassociate compute environments from a queue before submitting a DeleteJobQueue request.

Parameter Syntax

$result = $client->deleteJobQueue([
    'jobQueue' => '<string>', // REQUIRED
]);

DescribeComputeEnvironments

$result = $client->describeComputeEnvironments([/* ... */]);
$promise = $client->describeComputeEnvironmentsAsync([/* ... */]);

Describes one or more of your compute environments.

If you're using an unmanaged compute environment, you can use the DescribeComputeEnvironment operation to determine the ecsClusterArn that you launch your Amazon ECS container instances into.

Parameter Syntax

$result = $client->describeComputeEnvironments([
    'computeEnvironments' => ['<string>', ...],
    'maxResults' => <integer>,
    'nextToken' => '<string>',
]);

Parameter Details

Members
computeEnvironments
Type: Array of strings

A list of up to 100 compute environment names or full Amazon Resource Name (ARN) entries.

maxResults
Type: int

The maximum number of cluster results returned by DescribeComputeEnvironments in paginated output. When this parameter is used, DescribeComputeEnvironments only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another DescribeComputeEnvironments request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then DescribeComputeEnvironments returns up to 100 results and a nextToken value if applicable.

nextToken
Type: string

The nextToken value returned from a previous paginated DescribeComputeEnvironments 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.

Treat this token as an opaque identifier that's only used to retrieve the next items in a list and not for other programmatic purposes.

Result Details

Members
jobDefinitions
Type: Array of JobDefinition structures

The list of job definitions.

nextToken
Type: string

The nextToken value to include in a future DescribeJobDefinitions request. When the results of a DescribeJobDefinitions request exceed maxResults, this value can be used to retrieve the next page of results. This value is null when there are no more results to return.

Errors

ClientException:

These errors are usually caused by a client action. One example cause is using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Another cause is specifying an identifier that's not valid.

ServerException:

These errors are usually caused by a server issue.

DescribeJobQueues

$result = $client->describeJobQueues([/* ... */]);
$promise = $client->describeJobQueuesAsync([/* ... */]);

Describes one or more of your job queues.

Parameter Syntax

$result = $client->describeJobQueues([
    'jobQueues' => ['<string>', ...],
    'maxResults' => <integer>,
    'nextToken' => '<string>',
]);

Parameter Details

Members
jobQueues
Type: Array of strings

A list of up to 100 queue names or full queue Amazon Resource Name (ARN) entries.

maxResults
Type: int

The maximum number of results returned by DescribeJobQueues in paginated output. When this parameter is used, DescribeJobQueues 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 DescribeJobQueues request with the returned nextToken value. This value can be between 1 and 100. If this parameter isn't used, then DescribeJobQueues returns up to 100 results and a nextToken value if applicable.

nextToken
Type: string

The nextToken value returned from a previous paginated DescribeJobQueues 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.

Treat this token as an opaque identifier that's only used to retrieve the next items in a list and not for other programmatic purposes.

ListJobs

$result = $client->listJobs([/* ... */]);
$promise = $client->listJobsAsync([/* ... */]);

Returns a list of Batch jobs.

You must specify only one of the following items:

  • A job queue ID to return a list of jobs in that job queue

  • A multi-node parallel job ID to return a list of nodes for that job

  • An array job ID to return a list of the children for that job

You can filter the results by job status with the jobStatus parameter. If you don't specify a status, only RUNNING jobs are returned.

Parameter Syntax

$result = $client->listJobs([
    'arrayJobId' => '<string>',
    'filters' => [
        [
            'name' => '<string>',

    'maxResults' => <integer>,
    'multiNodeJobId' => '<string>',
    'nextToken' => '<string>',
]);

Parameter Details

Members
arrayJobId
Type: string

The job ID for an array job. Specifying an array job ID with this parameter lists all child jobs from within the specified array.

filters
Type: Array of KeyValuesPair structures

The filter to apply to the query. Only one filter can be used at a time. When the filter is used, jobStatus is ignored. The filter doesn't apply to child jobs in an array or multi-node parallel (MNP) jobs. The results are sorted by the createdAt field, with the most recent jobs being first.

JOB_NAME

The value of the filter is a case-insensitive match for the job name. If the value ends with an asterisk (*), the filter matches any job name that begins with the string before the '*'. This corresponds to the jobName value. For example, test1 matches both Test1 and test1, and test1* matches both test1 and Test10. When the JOB_NAME filter is used, the results are grouped by the job name and version.

JOB_DEFINITION

The value for the filter is the name or Amazon Resource Name (ARN) of the job definition. This corresponds to the jobDefinition value. The value is case sensitive. When the value for the filter is the job definition name, the results include all the jobs that used any revision of that job definition name. If the value ends with an asterisk (*), the filter matches any job definition name that begins with the string before the '*'. For example, jd1 matches only jd1, and jd1* matches both jd1 and jd1A. The version of the job definition that's used doesn't affect the sort order. When the JOB_DEFINITION filter is used and the ARN is used (which is in the form arn:${Partition}:batch:${Region}:${Account}:job-definition/${JobDefinitionName}:${Revision}), the results include jobs that used the specified revision of the job definition. Asterisk (*) isn't supported when the ARN is used.

BEFORE_CREATED_AT

The value for the filter is the time that's before the job was created. This corresponds to the createdAt value. The value is a string representation of the number of milliseconds since 00:00:00 UTC (midnight) on January 1, 1970.

AFTER_CREATED_AT

The value for the filter is the time that's after the job was created. This corresponds to the createdAt value. The value is a string representation of the number of milliseconds since 00:00:00 UTC (midnight) on January 1, 1970.

jobQueue
Type: string

The name or full Amazon Resource Name (ARN) of the job queue used to list jobs.

jobStatus
Type: string

The job status used to filter jobs in the specified queue. If the filters parameter is specified, the jobStatus parameter is ignored and jobs with any status are returned. If you don't specify a status, only RUNNING jobs are returned.

maxResults
Type: int

The maximum number of results returned by ListJobs in a paginated output. When this parameter is used, ListJobs returns up to maxResults results in a single page and a nextToken response element, if applicable. The remaining results of the initial request can be seen by sending another ListJobs request with the returned nextToken value.

The following outlines key parameters and limitations:

  • The minimum value is 1.

  • When --job-status is used, Batch returns up to 1000 values.

  • When --filters is used, Batch returns up to 100 values.

  • If neither parameter is used, then ListJobs returns up to 1000 results (jobs that are in the RUNNING status) and a nextToken value, if applicable.

multiNodeJobId
Type: string

The job ID for a multi-node parallel job. Specifying a multi-node parallel job ID with this parameter lists all nodes that are associated with the specified job.

nextToken
Type: string

The nextToken value returned from a previous paginated ListJobs 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.

Treat this token as an opaque identifier that's only used to retrieve the next items in a list and not for other programmatic purposes.

Parameter Details

Members
containerProperties
Type: ContainerProperties structure

An object with properties specific to Amazon ECS-based single-node container-based jobs. If the job definition's type parameter is container, then you must specify either containerProperties or nodeProperties. This must not be specified for Amazon EKS-based job definitions.

If the job runs on Fargate resources, then you must not specify nodeProperties; use only containerProperties.

ecsProperties
Type: EcsProperties structure

An object with properties that are specific to Amazon ECS-based jobs. This must not be specified for Amazon EKS-based job definitions.

eksProperties
Type: EksProperties structure

An object with properties that are specific to Amazon EKS-based jobs. This must not be specified for Amazon ECS based job definitions.

jobDefinitionName
Required: Yes
Type: 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 (_).

nodeProperties
Type: NodeProperties structure

An object with 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 runs on Fargate resources, then you must not specify nodeProperties; use containerProperties instead.

If the job runs on Amazon EKS resources, then you must not specify nodeProperties.

parameters
Type: Associative array of custom strings keys (String) to strings

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.

platformCapabilities
Type: Array of strings

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.

If the job runs on Amazon EKS resources, then you must not specify platformCapabilities.

propagateTags
Type: 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.

If the job runs on Amazon EKS resources, then you must not specify propagateTags.

retryStrategy
Type: RetryStrategy 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.

schedulingPriority
Type: int

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

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

tags
Type: Associative array of custom strings keys (TagKey) to strings

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.

timeout
Type: JobTimeout 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.

type
Required: Yes
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.

  • If the value is container, then one of the following is required: containerProperties, ecsProperties, or eksProperties.

  • If the value is multinode, then nodeProperties is required.

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

Result Syntax

[
    'jobDefinitionArn' => '<string>',
    'jobDefinitionName' => '<string>',
    'revision' => <integer>,
]

Result Details

Members
jobDefinitionArn
Required: Yes
Type: string

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

jobDefinitionName
Required: Yes
Type: string

The name of the job definition.

revision
Required: Yes
Type: int

The revision of the job definition.

Errors

ClientException:

These errors are usually caused by a client action. One example cause is using an action or resource on behalf of a user that doesn't have permissions to use the action or resource. Another cause is specifying an identifier that's not valid.

ServerException:

These errors are usually caused by a server issue.

Examples

Example 1: To register a job definition

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

$result = $client->registerJobDefinition([
    'type' => 'container',
    'containerProperties' => [
        'command' => [
            'sleep',
            '10',
        ],
        'image' => 'busybox',
        'resourceRequirements' => [
            [
                'type' => 'MEMORY',
                'value' => '128',
            ],
            [
                'type' => 'VCPU',
                'value' => '1',
            ],
        ],
    ],
    'jobDefinitionName' => 'sleep10',
]);

Result syntax:

[
    'jobDefinitionArn' => 'arn:aws:batch:us-east-1:012345678910:job-definition/sleep10:1',
    'jobDefinitionName' => 'sleep10',
    'revision' => 1,
]
Example 2: RegisterJobDefinition with tags

This demonstrates calling the RegisterJobDefinition action, including tags.

$result = $client->registerJobDefinition([
    'type' => 'container',
    'containerProperties' => [
        'command' => [
            'sleep',
            '30',
        ],
        'image' => 'busybox',
        'resourceRequirements' => [
            [
                'type' => 'MEMORY',
                'value' => '128',
            ],
            [
                'type' => 'VCPU',
                'value' => '1',
            ],
        ],
    ],
    'jobDefinitionName' => 'sleep30',
    'tags' => [
        'Department' => 'Engineering',
        'User' => 'JaneDoe',
    ],
]);

Result syntax:

[
    'jobDefinitionArn' => 'arn:aws:batch:us-east-1:012345678910:job-definition/sleep30:1',
    'jobDefinitionName' => 'sleep30',
    'revision' => 1,
]

SubmitJob

$result = $client->submitJob([/* ... */]);
$promise = $client->submitJobAsync([/* ... */]);

Submits an Batch job from a job definition. Parameters that are specified during SubmitJob override parameters defined in the job definition. vCPU and memory requirements that are specified in the resourceRequirements objects in the job definition are the exception. They can't be overridden this way using the memory and vcpus parameters. Rather, you must specify updates to job definition parameters in a resourceRequirements object that's included in the containerOverrides parameter.

Job queues with a scheduling policy are limited to 500 active fair share identifiers at a time.

Jobs that run on Fargate resources can't be guaranteed to run for more than 14 days. This is because, after 14 days, Fargate resources might become unavailable and job might be terminated.

Parameter Details

Members
arrayProperties
Type: ArrayProperties structure

The array properties for the submitted job, such as the size of the array. The array size can be between 2 and 10,000. If you specify array properties for a job, it becomes an array job. For more information, see Array Jobs in the Batch User Guide.

containerOverrides
Type: ContainerOverrides structure

An object with properties that override the defaults for the job definition that specify the name of a container in the specified job definition and the overrides it should receive. You can override the default command for a container, which is specified in the job definition or the Docker image, with a command override. You can also override existing environment variables on a container or add new environment variables to it with an environment override.

dependsOn
Type: Array of JobDependency structures

A list of dependencies for the job. A job can depend upon a maximum of 20 jobs. You can specify a SEQUENTIAL type dependency without specifying a job ID for array jobs so that each child array job completes sequentially, starting at index 0. You can also specify an N_TO_N type dependency with a job ID for array jobs. In that case, each index child of this job must wait for the corresponding index child of each dependency to complete before it can begin.

ecsPropertiesOverride
Type: EcsPropertiesOverride structure

An object, with properties that override defaults for the job definition, can only be specified for jobs that are run on Amazon ECS resources.

eksPropertiesOverride
Type: EksPropertiesOverride structure

An object, with properties that override defaults for the job definition, can only be specified for jobs that are run on Amazon EKS resources.

jobDefinition
Required: Yes
Type: string

The job definition used by this job. This value can be one of definition-name, definition-name:revision, or the Amazon Resource Name (ARN) for the job definition, with or without the revision (arn:aws:batch:region:account:job-definition/definition-name:revision , or arn:aws:batch:region:account:job-definition/definition-name ).

If the revision is not specified, then the latest active revision is used.

jobName
Required: Yes
Type: string

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

jobQueue
Required: Yes
Type: string

The job queue where the job is submitted. You can specify either the name or the Amazon Resource Name (ARN) of the queue.

nodeOverrides
Type: NodeOverrides structure

A list of node overrides in JSON format that specify the node range to target and the container overrides for that node range.

This parameter isn't applicable to jobs that are running on Fargate resources; use containerOverrides instead.

parameters
Type: Associative array of custom strings keys (String) to strings

Additional parameters passed to the job that replace parameter substitution placeholders that are set in the job definition. Parameters are specified as a key and value pair mapping. Parameters in a SubmitJob request override any corresponding parameter defaults from the job definition.

propagateTags
Type: 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 aren't 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. When specified, this overrides the tag propagation setting in the job definition.

retryStrategy
Type: RetryStrategy structure

The retry strategy to use for failed jobs from this SubmitJob operation. When a retry strategy is specified here, it overrides the retry strategy defined in the job definition.

schedulingPriorityOverride
Type: int

The scheduling priority for the job. This only affects jobs in job queues with a fair share policy. Jobs with a higher scheduling priority are scheduled before jobs with a lower scheduling priority. This overrides any scheduling priority in the job definition and works only within a single share identifier.

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

shareIdentifier
Type: string

The share identifier for the job. Don't specify this parameter if the job queue doesn't have a scheduling policy. If the job queue has a scheduling policy, then this parameter must be specified.

This string is limited to 255 alphanumeric characters, and can be followed by an asterisk (*).

tags
Type: Associative array of custom strings keys (TagKey) to strings

The tags that you apply to the job request 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 Amazon Web Services General Reference.

timeout
Type: JobTimeout structure

The timeout configuration for this SubmitJob operation. You can specify a timeout duration after which Batch terminates your jobs if they haven't finished. If a job is terminated due to a timeout, it isn't retried. The minimum value for the timeout is 60 seconds. This configuration overrides any timeout configuration specified in the job definition. For array jobs, child jobs have the same timeout configuration as the parent job. For more information, see Job Timeouts in the Amazon Elastic Container Service Developer Guide.

Parameter Details

Members
computeEnvironment
Required: Yes
Type: string

The name or full Amazon Resource Name (ARN) of the compute environment to update.

computeResources
Type: ComputeResourceUpdate structure

Details of the compute resources managed by the compute environment. Required for a managed compute environment. For more information, see Compute Environments in the Batch User Guide.

context
Type: string

Reserved.

serviceRole
Type: string

The full Amazon Resource Name (ARN) of the IAM role that allows Batch to make calls to other Amazon Web Services services on your behalf. For more information, see Batch service IAM role in the Batch User Guide.

If the compute environment has a service-linked role, it can't be changed to use a regular IAM role. Likewise, if the compute environment has a regular IAM role, it can't be changed to use a service-linked role. To update the parameters for the compute environment that require an infrastructure update to change, the AWSServiceRoleForBatch service-linked role must be used. For more information, see Updating compute environments in the Batch User Guide.

If your specified role has a path other than /, then you must either specify the full role ARN (recommended) or prefix the role name with the path.

Depending on how you created your Batch service role, its ARN might contain the service-role path prefix. When you only specify the name of the service role, Batch assumes that your ARN doesn't use the service-role path prefix. Because of this, we recommend that you specify the full ARN of your service role when you create compute environments.

state
Type: string

The state of the compute environment. Compute environments in the ENABLED state can accept jobs from a queue and scale in or out automatically based on the workload demand of its associated queues.

If the state is ENABLED, then the Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically, based on the job queue demand.

If the state is DISABLED, then the Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out.

Compute environments in a DISABLED state may continue to incur billing charges. To prevent additional charges, turn off and then delete the compute environment. For more information, see State in the Batch User Guide.

When an instance is idle, the instance scales down to the minvCpus value. However, the instance size doesn't change. For example, consider a c5.8xlarge instance with a minvCpus value of 4 and a desiredvCpus value of 36. This instance doesn't scale down to a c5.large instance.

unmanagedvCpus
Type: int

The maximum number of vCPUs expected to be used for an unmanaged compute environment. Don't specify this parameter for a managed compute environment. This parameter is only used for fair share scheduling to reserve vCPU capacity for new share identifiers. If this parameter isn't provided for a fair share job queue, no vCPU capacity is reserved.

updatePolicy
Type: UpdatePolicy structure

Specifies the updated infrastructure update policy for the compute environment. For more information about infrastructure updates, see Updating compute environments in the Batch User Guide.

Result Syntax

[
    'computeEnvironmentArn' => '<string>',
    'computeEnvironmentName' => '<string>',

]);

Parameter Details

Members
computeEnvironmentOrder
Type: Array of ComputeEnvironmentOrder structures

Details the set of compute environments mapped to a job queue and their order relative to each other. This is one of the parameters used by the job scheduler to determine which compute environment runs a given job. Compute environments must be in the VALID state before you can associate them with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT). EC2 and Fargate compute environments can't be mixed.

All compute environments that are associated with a job queue must share the same architecture. Batch doesn't support mixing compute environment architecture types in a single job queue.

jobQueue
Required: Yes
Type: string

The name or the Amazon Resource Name (ARN) of the job queue.

jobStateTimeLimitActions
Type: Array of JobStateTimeLimitAction structures

The set of actions that Batch perform on jobs that remain at the head of the job queue in the specified state longer than specified times. Batch will perform each action after maxTimeSeconds has passed.

priority
Type: int

The priority of the job queue. Job queues with a higher priority (or a higher integer value for the priority parameter) are evaluated first when associated with the same compute environment. Priority is determined in descending order. For example, a job queue with a priority value of 10 is given scheduling preference over a job queue with a priority value of 1. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT). EC2 and Fargate compute environments can't be mixed.

schedulingPolicyArn
Type: string

Amazon Resource Name (ARN) of the fair share scheduling policy. Once a job queue is created, the fair share scheduling policy can be replaced but not removed. The format is aws:Partition:batch:Region:Account:scheduling-policy/Name . For example, aws:aws:batch:us-west-2:123456789012:scheduling-policy/MySchedulingPolicy.

state
Type: string

Describes the queue's ability to accept new jobs. If the job queue state is ENABLED, it can accept jobs. If the job queue state is DISABLED, new jobs can't be added to the queue, but jobs already in the queue can finish.

state
Type: string

The state of the compute environment. The valid values are ENABLED or DISABLED.

If the state is ENABLED, then the Batch scheduler can attempt to place jobs from an associated job queue on the compute resources within the environment. If the compute environment is managed, then it can scale its instances out or in automatically based on the job queue demand.

If the state is DISABLED, then the Batch scheduler doesn't attempt to place jobs within the environment. Jobs in a STARTING or RUNNING state continue to progress normally. Managed compute environments in the DISABLED state don't scale out.

Compute environments in a DISABLED state may continue to incur billing charges. To prevent additional charges, turn off and then delete the compute environment. For more information, see State in the Batch User Guide.

When an instance is idle, the instance scales down to the minvCpus value. However, the instance size doesn't change. For example, consider a c5.8xlarge instance with a minvCpus value of 4 and a desiredvCpus value of 36. This instance doesn't scale down to a c5.large instance.

For example, if two compute environments are associated with a job queue, the compute environment with a lower order integer value is tried for job placement first. Compute environments must be in the VALID state before you can associate them with a job queue. All of the compute environments must be either EC2 (EC2 or SPOT) or Fargate (FARGATE or FARGATE_SPOT); Amazon EC2 and Fargate compute environments can't be mixed.

All compute environments that are associated with a job queue must share the same architecture. Batch doesn't support mixing compute environment architecture types in a single job queue.

Members

order
Required: Yes
Type: int

The order of the compute environment. Compute environments are tried in ascending order. For example, if two compute environments are associated with a job queue, the compute environment with a lower order integer value is tried for job placement first.

ComputeResource

Description

An object that represents an Batch compute resource. For more information, see Compute environments in the Batch User Guide.

Members
allocationStrategy
Type: string

The allocation strategy to use for the compute resource if not enough instances of the best fitting instance type can be allocated. This might be because of availability of the instance type in the Region or Amazon EC2 service limits. For more information, see Allocation strategies in the Batch User Guide.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

BEST_FIT (default)

Batch selects an instance type that best fits the needs of the jobs with a preference for the lowest-cost instance type. If additional instances of the selected instance type aren't available, Batch waits for the additional instances to be available. If there aren't enough instances available or the user is reaching Amazon EC2 service limits, additional jobs aren't run until the currently running jobs are completed. This allocation strategy keeps costs lower but can limit scaling. If you're using Spot Fleets with BEST_FIT, the Spot Fleet IAM Role must be specified. Compute resources that use a BEST_FIT allocation strategy don't support infrastructure updates and can't update some parameters. For more information, see Updating compute environments in the Batch User Guide.

BEST_FIT_PROGRESSIVE

Batch selects additional instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types with lower cost vCPUs. If additional instances of the previously selected instance types aren't available, Batch selects new instance types.

SPOT_CAPACITY_OPTIMIZED

Batch selects one or more instance types that are large enough to meet the requirements of the jobs in the queue. Its preference is for instance types that are less likely to be interrupted. This allocation strategy is only available for Spot Instance compute resources.

SPOT_PRICE_CAPACITY_OPTIMIZED

The price and capacity optimized allocation strategy looks at both price and capacity to select the Spot Instance pools that are the least likely to be interrupted and have the lowest possible price. This allocation strategy is only available for Spot Instance compute resources.

With BEST_FIT_PROGRESSIVE,SPOT_CAPACITY_OPTIMIZED and SPOT_PRICE_CAPACITY_OPTIMIZED (recommended) strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.

bidPercentage
Type: int

The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched. For example, if your maximum percentage is 20%, then the Spot price must be less than 20% of the current On-Demand price for that Amazon EC2 instance. You always pay the lowest (market) price and never more than your maximum percentage. If you leave this field empty, the default value is 100% of the On-Demand price. For most use cases, we recommend leaving this field empty.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

desiredvCpus
Type: int

The desired number of vCPUS in the compute environment. Batch modifies this value between the minimum and maximum values based on job queue demand.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

ec2Configuration

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

imageId
Type: string

The Amazon Machine Image (AMI) ID used for instances launched in the compute environment. This parameter is overridden by the imageIdOverride member of the Ec2Configuration structure.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

The AMI that you choose for a compute environment must match the architecture of the instance types that you intend to use for that compute environment. For example, if your compute environment uses A1 instance types, the compute resource AMI that you choose must support ARM instances. Amazon ECS vends both x86 and ARM versions of the Amazon ECS-optimized Amazon Linux 2 AMI. For more information, see Amazon ECS-optimized Amazon Linux 2 AMI in the Amazon Elastic Container Service Developer Guide.

instanceRole
Type: string

The Amazon ECS instance profile applied to Amazon EC2 instances in a compute environment. This parameter is required for Amazon EC2 instances types. You can specify the short name or full Amazon Resource Name (ARN) of an instance profile. For example, ecsInstanceRole or arn:aws:iam::<aws_account_id>:instance-profile/ecsInstanceRole . For more information, see Amazon ECS instance role in the Batch User Guide.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

instanceTypes
Type: Array of strings

The instances types that can be launched. You can specify instance families to launch any instance type within those families (for example, c5 or p3), or you can specify specific sizes within a family (such as c5.8xlarge). You can also choose optimal to select instance types (from the C4, M4, and R4 instance families) that match the demand of your job queues.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

When you create a compute environment, the instance types that you select for the compute environment must share the same architecture. For example, you can't mix x86 and ARM instances in the same compute environment.

Currently, optimal uses instance types from the C4, M4, and R4 instance families. In Regions that don't have instance types from those instance families, instance types from the C5, M5, and R5 instance families are used.

launchTemplate
Type: LaunchTemplateSpecification structure

The launch template to use for your compute resources. Any other compute resource parameters that you specify in a CreateComputeEnvironment API operation override the same parameters in the launch template. You must specify either the launch template ID or launch template name in the request, but not both. For more information, see Launch template support in the Batch User Guide.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

maxvCpus
Required: Yes
Type: int

The maximum number of vCPUs that a compute environment can support.

With BEST_FIT_PROGRESSIVE,SPOT_CAPACITY_OPTIMIZED and SPOT_PRICE_CAPACITY_OPTIMIZED (recommended) strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.

minvCpus
Type: int

The minimum number of vCPUs that a compute environment should maintain (even if the compute environment is DISABLED).

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

placementGroup
Type: string

The Amazon EC2 placement group to associate with your compute resources. If you intend to submit multi-node parallel jobs to your compute environment, you should consider creating a cluster placement group and associate it with your compute resources. This keeps your multi-node parallel job on a logical grouping of instances within a single Availability Zone with high network flow potential. For more information, see Placement groups in the Amazon EC2 User Guide for Linux Instances.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

securityGroupIds
Type: Array of strings

The Amazon EC2 security groups that are associated with instances launched in the compute environment. One or more security groups must be specified, either in securityGroupIds or using a launch template referenced in launchTemplate. This parameter is required for jobs that are running on Fargate resources and must contain at least one security group. Fargate doesn't support launch templates. If security groups are specified using both securityGroupIds and launchTemplate, the values in securityGroupIds are used.

spotIamFleetRole
Type: string

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

To tag your Spot Instances on creation, the Spot Fleet IAM role specified here must use the newer AmazonEC2SpotFleetTaggingRole managed policy. The previously recommended AmazonEC2SpotFleetRole managed policy doesn't have the required permissions to tag Spot Instances. For more information, see Spot instances not tagged on creation in the Batch User Guide.

subnets
Required: Yes
Type: Array of strings

The VPC subnets where the compute resources are launched. These subnets must be within the same VPC. Fargate compute resources can contain up to 16 subnets. For more information, see VPCs and subnets in the Amazon VPC User Guide.

Batch on Amazon EC2 and Batch on Amazon EKS support Local Zones. For more information, see Local Zones in the Amazon EC2 User Guide for Linux Instances, Amazon EKS and Amazon Web Services Local Zones in the Amazon EKS User Guide and Amazon ECS clusters in Local Zones, Wavelength Zones, and Amazon Web Services Outposts in the Amazon ECS Developer Guide.

Batch on Fargate doesn't currently support Local Zones.

tags
Type: Associative array of custom strings keys (String) to strings

Key-value pair tags to be applied to Amazon EC2 resources that are launched in the compute environment. For Batch, these take the form of "String1": "String2", where String1 is the tag key and String2 is the tag value-for example, { "Name": "Batch Instance - C4OnDemand" }. This is helpful for recognizing your Batch instances in the Amazon EC2 console. Updating these tags requires an infrastructure update to the compute environment. For more information, see Updating compute environments in the Batch User Guide. These tags aren't seen when using the Batch ListTagsForResource API operation.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't specify it.

type
Required: Yes
Type: string

With BEST_FIT_PROGRESSIVE,SPOT_CAPACITY_OPTIMIZED and SPOT_PRICE_CAPACITY_OPTIMIZED (recommended) strategies using On-Demand or Spot Instances, and the BEST_FIT strategy using Spot Instances, Batch might need to exceed maxvCpus to meet your capacity requirements. In this event, Batch never exceeds maxvCpus by more than a single instance.

bidPercentage
Type: int

The maximum percentage that a Spot Instance price can be when compared with the On-Demand price for that instance type before instances are launched. For example, if your maximum percentage is 20%, the Spot price must be less than 20% of the current On-Demand price for that Amazon EC2 instance. You always pay the lowest (market) price and never more than your maximum percentage. For most use cases, we recommend leaving this field empty.

When updating a compute environment, changing the bid percentage requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide.

For Amazon EC2 compute resources, providing an empty list removes the VPC subnets from the compute resource. For more information, see VPCs and subnets in the Amazon VPC User Guide.

When updating a compute environment, changing the VPC subnets requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide.

Batch on Amazon EC2 and Batch on Amazon EKS support Local Zones. For more information, see Local Zones in the Amazon EC2 User Guide for Linux Instances, Amazon EKS and Amazon Web Services Local Zones in the Amazon EKS User Guide and Amazon ECS clusters in Local Zones, Wavelength Zones, and Amazon Web Services Outposts in the Amazon ECS Developer Guide.

Batch on Fargate doesn't currently support Local Zones.

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.

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 in to your container instance and run the following command: sudo docker version | grep "Server API version"

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.

LaunchTemplateSpecification

Description

An object that represents a launch template that's associated with a compute resource. You must specify either the launch template ID or launch template name in the request, but not both.

If security groups are specified using both the securityGroupIds parameter of CreateComputeEnvironment and the launch template, the values in the securityGroupIds parameter of CreateComputeEnvironment will be used.

This object isn't applicable to jobs that are running on Fargate resources.

Members
launchTemplateId
Type: string

The ID of the launch template.

launchTemplateName
Type: string

The name of the launch template.

version
Type: string

The version number of the launch template, $Latest, or $Default.

If the value is $Latest, the latest version of the launch template is used. If the value is $Default, the default version of the launch template is used.

If the AMI ID that's used in a compute environment is from the launch template, the AMI isn't changed when the compute environment is updated. It's only changed if the updateToLatestImageVersion parameter for the compute environment is set to true. During an infrastructure update, if either $Latest or $Default is specified, Batch re-evaluates the launch template version, and it might use a different version of the launch template. This is the case even if the launch template isn't specified in the update. When updating a compute environment, changing the launch template requires an infrastructure update of the compute environment. For more information, see Updating compute environments in the Batch User Guide.

Default: $Default.

LinuxParameters

Description

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

Members
devices
Type: Array of Device structures

Any of the 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.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.

initProcessEnabled
Type: 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 in to your container instance and run the following command: sudo docker version | grep "Server API version"

maxSwap
Type: int

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 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 that it's running on. A maxSwap value must be set for the swappiness parameter to be used.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.

sharedMemorySize
Type: int

The value for the size (in MiB) of the /dev/shm volume. This parameter maps to the --shm-size option to docker run.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.

swappiness
Type: int

You can use this parameter to tune a container's memory swappiness behavior. A swappiness value of 0 causes swapping to not occur unless absolutely necessary. A swappiness value of 100 causes pages to be swapped aggressively. Valid 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.

    By default, the Amazon ECS optimized AMIs don't have swap enabled. 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 has a default swappiness value of 60. Moreover, the total swap usage is limited to two times the memory reservation of the container.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide it for these jobs.

tmpfs
Type: Array of Tmpfs structures

The container path, mount options, and size (in MiB) of the tmpfs mount. This parameter maps to the --tmpfs option to docker run.

This parameter isn't applicable to jobs that are running on Fargate resources. Don't provide this parameter for this resource type.

The vCPU architecture. The default value is X86_64. Valid values are X86_64 and ARM64.

This parameter must be set to X86_64 for Windows containers.

Fargate Spot is not supported for ARM64 and Windows-based containers on Fargate. A job queue will be blocked if a Fargate ARM64 or Windows job is submitted to a job queue with only Fargate Spot compute environments. However, you can attach both FARGATE and FARGATE_SPOT compute environments to the same job queue.

operatingSystemFamily
Type: string

The operating system for the compute environment. Valid values are: LINUX (default), WINDOWS_SERVER_2019_CORE, WINDOWS_SERVER_2019_FULL, WINDOWS_SERVER_2022_CORE, and WINDOWS_SERVER_2022_FULL.

The following parameters can’t be set for Windows containers: linuxParameters, privileged, user, ulimits, readonlyRootFilesystem, and efsVolumeConfiguration.

The Batch Scheduler checks the compute environments that are attached to the job queue before registering a task definition with Fargate. In this scenario, the job queue is where the job is submitted. If the job requires a Windows container and the first compute environment is LINUX, the compute environment is skipped and the next compute environment is checked until a Windows-based compute environment is found.

Fargate Spot is not supported for ARM64 and Windows-based containers on Fargate. A job queue will be blocked if a Fargate ARM64 or Windows job is submitted to a job queue with only Fargate Spot compute environments. However, you can attach both FARGATE and FARGATE_SPOT compute environments to the same job queue.

Description

Specifies the weights for the fair share identifiers for the fair share policy. Fair share identifiers that aren't included have a default weight of 1.0.

Members
shareIdentifier
Required: Yes
Type: string

A fair share identifier or fair share identifier prefix. If the string ends with an asterisk (*), this entry specifies the weight factor to use for fair share identifiers that start with that prefix. The list of fair share identifiers in a fair share policy can't overlap. For example, you can't have one that specifies a shareIdentifier of UserA* and another that specifies a shareIdentifier of UserA-1.

There can be no more than 500 fair share identifiers active in a job queue.

The string is limited to 255 alphanumeric characters, and can be followed by an asterisk (*).

weightFactor
Type: float

The weight factor for the fair share identifier. The default value is 1.0. A lower value has a higher priority for compute resources. For example, jobs that use a share identifier with a weight factor of 0.125 (1/8) get 8 times the compute resources of jobs that use a share identifier with a weight factor of 1.

The smallest supported value is 0.0001, and the largest supported value is 999.9999.

A list of containers that this container depends on.

environment
Type: Array of KeyValuePair structures

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.

We don't recommend using plaintext environment variables for sensitive information, such as credential data.

essential
Type: boolean

If the essential parameter of a container is marked as true, and that container fails or stops for any reason, all other containers that are part of the task are stopped. If the essential parameter of a container is marked as false, its failure doesn't affect the rest of the containers in a task. If this parameter is omitted, a container is assumed to be essential.

All jobs must have at least one essential container. If you have an application that's composed of multiple containers, group containers that are used for a common purpose into components, and separate the different components into multiple task definitions. For more information, see Application Architecture in the Amazon Elastic Container Service Developer Guide.

exitCode
Type: int

The exit code returned upon completion.

Type: LinuxParameters structure

Linux-specific modifications that are applied to the container, such as Linux kernel capabilities. For more information, see KernelCapabilities.

This parameter is not supported for Windows containers.

logConfiguration
Type: 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 can use a different logging driver than the Docker daemon by specifying a log driver with this parameter in the container definition. To use a different logging driver for a container, the log system must be configured properly on the container instance (or on a different log server for remote logging options). For more information about the options for different supported log drivers, see Configure logging drivers in the Docker documentation.

Amazon ECS currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type). Additional log drivers may be available in future releases of the Amazon ECS container agent.

This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

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.

logStreamName
Type: string

This parameter is not supported for Windows containers or tasks run on Fargate.

readonlyRootFilesystem
Type: 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.

This parameter is not supported for Windows containers.

The secrets to pass to the container. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.

ulimits
Type: Array of Ulimit structures

A list of ulimits to set in the container. If a ulimit value is specified in a task definition, it overrides the default values set by Docker. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run.

Amazon ECS tasks hosted on Fargate use the default resource limit values set by the operating system with the exception of the nofile resource limit parameter which Fargate overrides. The nofile resource limit sets a restriction on the number of open files that a container can use. The default nofile soft limit is 1024 and the default hard limit is 65535.

This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the Docker Remote API version on your container instance, log in to your container instance and run the following command: sudo docker version --format '{{.Server.APIVersion}}'

This parameter is not supported for Windows containers.

user
Type: string

The user to use inside the container. This parameter maps to User in the Create a container section of the Docker Remote API and the --user option to docker run.

When running tasks using the host network mode, don't run containers using the root user (UID 0). We recommend using a non-root user for better security.

You can specify the user using the following formats. If specifying a UID or GID, you must specify it as a positive integer.

  • user

  • user:group

  • uid

  • uid:gid

  • user:gi
