AWS Batch Construct Library

This module is part of the AWS Cloud Development Kit project.

AWS Batch is a batch processing tool for efficiently running hundreds of thousands computing jobs in AWS. Batch can dynamically provision different types of compute resources based on the resource requirements of submitted jobs.

AWS Batch simplifies the planning, scheduling, and executions of your batch workloads across a full range of compute services like Amazon EC2 and Spot Resources.

Batch achieves this by utilizing queue processing of batch job requests. To successfully submit a job for execution, you need the following resources:

  1. Job Definition - Group various job properties (container image, resource requirements, env variables...) into a single definition. These definitions are used at job submission time.
  2. Compute Environment - the execution runtime of submitted batch jobs
  3. Job Queue - the queue where batch jobs can be submitted to via AWS SDK/CLI

For more information on AWS Batch visit the AWS Docs for Batch.

Compute Environment

At the core of AWS Batch is the compute environment. All batch jobs are processed within a compute environment, which uses resource like OnDemand/Spot EC2 instances or Fargate.

In MANAGED mode, AWS will handle the provisioning of compute resources to accommodate the demand. Otherwise, in UNMANAGED mode, you will need to manage the provisioning of those resources.

Below is an example of each available type of compute environment:

var vpc vpc


// default is managed
awsManagedEnvironment := batch.NewComputeEnvironment(this, jsii.String("AWS-Managed-Compute-Env"), &computeEnvironmentProps{
	computeResources: &computeResources{
		vpc: vpc,
	},
})

customerManagedEnvironment := batch.NewComputeEnvironment(this, jsii.String("Customer-Managed-Compute-Env"), &computeEnvironmentProps{
	managed: jsii.Boolean(false),
})
Spot-Based Compute Environment

It is possible to have AWS Batch submit spotfleet requests for obtaining compute resources. Below is an example of how this can be done:

vpc := ec2.NewVpc(this, jsii.String("VPC"))

spotEnvironment := batch.NewComputeEnvironment(this, jsii.String("MySpotEnvironment"), &computeEnvironmentProps{
	computeResources: &computeResources{
		type: batch.computeResourceType_SPOT,
		bidPercentage: jsii.Number(75),
		 // Bids for resources at 75% of the on-demand price
		vpc: vpc,
	},
})
Fargate Compute Environment

It is possible to have AWS Batch submit jobs to be run on Fargate compute resources. Below is an example of how this can be done:

vpc := ec2.NewVpc(this, jsii.String("VPC"))

fargateSpotEnvironment := batch.NewComputeEnvironment(this, jsii.String("MyFargateEnvironment"), &computeEnvironmentProps{
	computeResources: &computeResources{
		type: batch.computeResourceType_FARGATE_SPOT,
		vpc: vpc,
	},
})
Understanding Progressive Allocation Strategies

AWS Batch uses an allocation strategy to determine what compute resource will efficiently handle incoming job requests. By default, BEST_FIT will pick an available compute instance based on vCPU requirements. If none exist, the job will wait until resources become available. However, with this strategy, you may have jobs waiting in the queue unnecessarily despite having more powerful instances available. Below is an example of how that situation might look like:

Compute Environment:

1. m5.xlarge => 4 vCPU
2. m5.2xlarge => 8 vCPU

Job Queue:
---------
| A | B |
---------

Job Requirements:
A => 4 vCPU - ALLOCATED TO m5.xlarge
B => 2 vCPU - WAITING

In this situation, Batch will allocate Job A to compute resource #1 because it is the most cost efficient resource that matches the vCPU requirement. However, with this BEST_FIT strategy, Job B will not be allocated to our other available compute resource even though it is strong enough to handle it. Instead, it will wait until the first job is finished processing or wait a similar m5.xlarge resource to be provisioned.

The alternative would be to use the BEST_FIT_PROGRESSIVE strategy in order for the remaining job to be handled in larger containers regardless of vCPU requirement and costs.

Launch template support

Simply define your Launch Template:

// This example is only available in TypeScript
const myLaunchTemplate = new ec2.CfnLaunchTemplate(this, 'LaunchTemplate', {
  launchTemplateName: 'extra-storage-template',
  launchTemplateData: {
    blockDeviceMappings: [
      {
        deviceName: '/dev/xvdcz',
        ebs: {
          encrypted: true,
          volumeSize: 100,
          volumeType: 'gp2',
        },
      },
    ],
  },
});

and use it:

var vpc vpc
var myLaunchTemplate cfnLaunchTemplate


myComputeEnv := batch.NewComputeEnvironment(this, jsii.String("ComputeEnv"), &computeEnvironmentProps{
	computeResources: &computeResources{
		launchTemplate: &launchTemplateSpecification{
			launchTemplateName: string(myLaunchTemplate.launchTemplateName),
		},
		vpc: vpc,
	},
	computeEnvironmentName: jsii.String("MyStorageCapableComputeEnvironment"),
})
Importing an existing Compute Environment

To import an existing batch compute environment, call ComputeEnvironment.fromComputeEnvironmentArn().

Below is an example:

computeEnv := batch.computeEnvironment.fromComputeEnvironmentArn(this, jsii.String("imported-compute-env"), jsii.String("arn:aws:batch:us-east-1:555555555555:compute-environment/My-Compute-Env"))
Change the baseline AMI of the compute resources

Occasionally, you will need to deviate from the default processing AMI.

ECS Optimized Amazon Linux 2 example:

var vpc vpc

myComputeEnv := batch.NewComputeEnvironment(this, jsii.String("ComputeEnv"), &computeEnvironmentProps{
	computeResources: &computeResources{
		image: ecs.NewEcsOptimizedAmi(&ecsOptimizedAmiProps{
			generation: ec2.amazonLinuxGeneration_AMAZON_LINUX_2,
		}),
		vpc: vpc,
	},
})

Custom based AMI example:

var vpc vpc

myComputeEnv := batch.NewComputeEnvironment(this, jsii.String("ComputeEnv"), &computeEnvironmentProps{
	computeResources: &computeResources{
		image: ec2.machineImage.genericLinux(map[string]*string{
			"[aws-region]": jsii.String("[ami-ID]"),
		}),
		vpc: vpc,
	},
})

Job Queue

Jobs are always submitted to a specific queue. This means that you have to create a queue before you can start submitting jobs. Each queue is mapped to at least one (and no more than three) compute environment. When the job is scheduled for execution, AWS Batch will select the compute environment based on ordinal priority and available capacity in each environment.

var computeEnvironment computeEnvironment

jobQueue := batch.NewJobQueue(this, jsii.String("JobQueue"), &jobQueueProps{
	computeEnvironments: []jobQueueComputeEnvironment{
		&jobQueueComputeEnvironment{
			// Defines a collection of compute resources to handle assigned batch jobs
			computeEnvironment: computeEnvironment,
			// Order determines the allocation order for jobs (i.e. Lower means higher preference for job assignment)
			order: jsii.Number(1),
		},
	},
})
Priorty-Based Queue Example

Sometimes you might have jobs that are more important than others, and when submitted, should take precedence over the existing jobs. To achieve this, you can create a priority based execution strategy, by assigning each queue its own priority:

var sharedComputeEnvs computeEnvironment

highPrioQueue := batch.NewJobQueue(this, jsii.String("JobQueue"), &jobQueueProps{
	computeEnvironments: []jobQueueComputeEnvironment{
		&jobQueueComputeEnvironment{
			computeEnvironment: sharedComputeEnvs,
			order: jsii.Number(1),
		},
	},
	priority: jsii.Number(2),
})

lowPrioQueue := batch.NewJobQueue(this, jsii.String("JobQueue"), &jobQueueProps{
	computeEnvironments: []*jobQueueComputeEnvironment{
		&jobQueueComputeEnvironment{
			computeEnvironment: sharedComputeEnvs,
			order: jsii.Number(1),
		},
	},
	priority: jsii.Number(1),
})

By making sure to use the same compute environments between both job queues, we will give precedence to the highPrioQueue for the assigning of jobs to available compute environments.

Importing an existing Job Queue

To import an existing batch job queue, call JobQueue.fromJobQueueArn().

Below is an example:

jobQueue := batch.jobQueue.fromJobQueueArn(this, jsii.String("imported-job-queue"), jsii.String("arn:aws:batch:us-east-1:555555555555:job-queue/High-Prio-Queue"))

Job Definition

A Batch Job definition helps AWS Batch understand important details about how to run your application in the scope of a Batch Job. This involves key information like resource requirements, what containers to run, how the compute environment should be prepared, and more. Below is a simple example of how to create a job definition:

import ecr "github.com/aws/aws-cdk-go/awscdk"


repo := ecr.repository.fromRepositoryName(this, jsii.String("batch-job-repo"), jsii.String("todo-list"))

batch.NewJobDefinition(this, jsii.String("batch-job-def-from-ecr"), &jobDefinitionProps{
	container: &jobDefinitionContainer{
		image: ecs.NewEcrImage(repo, jsii.String("latest")),
	},
})
Using a local Docker project

Below is an example of how you can create a Batch Job Definition from a local Docker application.

batch.NewJobDefinition(this, jsii.String("batch-job-def-from-local"), &jobDefinitionProps{
	container: &jobDefinitionContainer{
		// todo-list is a directory containing a Dockerfile to build the application
		image: ecs.containerImage.fromAsset(jsii.String("../todo-list")),
	},
})
Providing custom log configuration

You can provide custom log driver and its configuration for the container.

import ssm "github.com/aws/aws-cdk-go/awscdk"


batch.NewJobDefinition(this, jsii.String("job-def"), &jobDefinitionProps{
	container: &jobDefinitionContainer{
		image: ecs.ecrImage.fromRegistry(jsii.String("docker/whalesay")),
		logConfiguration: &logConfiguration{
			logDriver: batch.logDriver_AWSLOGS,
			options: map[string]*string{
				"awslogs-region": jsii.String("us-east-1"),
			},
			secretOptions: []exposedSecret{
				batch.*exposedSecret.fromParametersStore(jsii.String("xyz"), ssm.stringParameter.fromStringParameterName(this, jsii.String("parameter"), jsii.String("xyz"))),
			},
		},
	},
})
Importing an existing Job Definition
From ARN

To import an existing batch job definition from its ARN, call JobDefinition.fromJobDefinitionArn().

Below is an example:

job := batch.jobDefinition.fromJobDefinitionArn(this, jsii.String("imported-job-definition"), jsii.String("arn:aws:batch:us-east-1:555555555555:job-definition/my-job-definition"))
From Name

To import an existing batch job definition from its name, call JobDefinition.fromJobDefinitionName(). If name is specified without a revision then the latest active revision is used.

Below is an example:

// Without revision
job1 := batch.jobDefinition.fromJobDefinitionName(this, jsii.String("imported-job-definition"), jsii.String("my-job-definition"))

// With revision
job2 := batch.jobDefinition.fromJobDefinitionName(this, jsii.String("imported-job-definition"), jsii.String("my-job-definition:3"))

However, if you can continue to roll it back, you can return the stack to its original settings and then try to update it again.

A CloudFormation `AWS::Batch::ComputeEnvironment`.

The `AWS::Batch::ComputeEnvironment` resource defines your AWS Batch compute environment. You can define `MANAGED` or `UNMANAGED` compute environments. `MANAGED` compute environments can use Amazon EC2 or AWS Fargate resources. `UNMANAGED` compute environments can only use EC2 resources. For more information, see [Compute Environments](https://docs.aws.amazon.com/batch/latest/userguide/compute_environments.html) in the ** .

In a managed compute environment, AWS 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](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-launch-templates.html) that you specify when you create the compute environment. You can choose either to use EC2 On-Demand Instances and EC2 Spot Instances, or to 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 below a specified percentage of the On-Demand price.

> Multi-node parallel jobs are not supported on Spot Instances.

In an unmanaged compute environment, you can manage your own EC2 compute resources and have a lot of flexibility with how you configure your compute resources. For example, you can use custom AMI. However, you need to verify that your AMI meets the Amazon ECS container instance AMI specification. For more information, see [container instance AMIs](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/container_instance_AMIs.html) in the *Amazon Elastic Container Service Developer Guide* . After you have created your unmanaged compute environment, you can use the [DescribeComputeEnvironments](https://docs.aws.amazon.com/batch/latest/APIReference/API_DescribeComputeEnvironments.html) operation to find the Amazon ECS cluster that is associated with it. Then, manually launch your container instances into that Amazon ECS cluster. For more information, see [Launching an Amazon ECS container instance](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/launch_container_instance.html) in the *Amazon Elastic Container Service Developer Guide* .

> AWS Batch doesn't upgrade the AMIs in a compute environment after it's created except under specific conditions. For example, it doesn't automatically update the AMIs when a newer version of the Amazon ECS optimized AMI is available. Therefore, you're responsible for the management of the guest operating system (including updates and security patches) and any additional application software or utilities that you install on the compute resources. There are two ways to use a new AMI for your AWS Batch jobs. The original method is to complete these steps: > > - Create a new compute environment with the new AMI. > - Add the compute environment to an existing job queue. > - Remove the earlier compute environment from your job queue. > - Delete the earlier compute environment. > > In April 2022, AWS Batch added enhanced support for updating compute environments. For more information, see [Updating compute environments](https://docs.aws.amazon.com/batch/latest/userguide/updating-compute-environments.html) in the *AWS Batch User Guide* . To use the enhanced updating of compute environments to update AMIs, follow these rules: > > - Either do not set the [ServiceRole](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-batch-computeenvironment.html#cfn-batch-computeenvironment-servicerole) property or set it to the *AWSServiceRoleForBatch* service-linked role. > - Set the AllocationStrategy(https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-batch-computeenvironment-computeresources.html#cfn-batch-computeenvironment-computeresources-allocationstrategy) property to `BEST_FIT_PROGRESSIVE` or `SPOT_CAPACITY_OPTIMIZED` . > - Set the [ReplaceComputeEnvironment](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-batch-computeenvironment.html#cfn-batch-computeenvironment-replacecomputeenvironment) property to `false` . > - Set the [UpdateToLatestImageVersion](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-batch-computeenvironment-computeresources.html#cfn-batch-computeenvironment-computeresources-updatetolatestimageversion) property to `true` . > - Either do not specify an image ID in [ImageId](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-batch-computeenvironment-computeresources.html#cfn-batch-computeenvironment-computeresources-imageid) or [ImageIdOverride](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-batch-computeenvironment-ec2configurationobject.html#cfn-batch-computeenvironment-ec2configurationobject-imageidoverride) properties, or in the launch template identified by the [Launch Template](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-batch-computeenvironment-computeresources.html#cfn-batch-computeenvironment-computeresources-launchtemplate) property. In that case AWS Batch will select the latest Amazon ECS optimized AMI supported by AWS Batch at the time the infrastructure update is initiated. Alternatively you can specify the AMI ID in the `ImageId` or `ImageIdOverride` properties, or the launch template identified by the `LaunchTemplate` properties. Changing any of these properties will trigger an infrastructure update. > > If these rules are followed, any update that triggers an infrastructure update will cause the AMI ID to be re-selected. If the [Version](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-batch-computeenvironment-launchtemplatespecification.html#cfn-batch-computeenvironment-launchtemplatespecification-version) property of the LaunchTemplateSpecification(https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-batch-computeenvironment-launchtemplatespecification.html) is set to `$Latest` or `$Default` , the latest or default version of the launch template will be evaluated up at the time of the infrastructure update, even if the `LaunchTemplateSpecification` was not updated.

	// - **BEST_FIT (default)** - AWS 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, AWS Batch waits for the additional instances to be available. If there aren't enough instances available, or if the user is reaching [Amazon EC2 service limits](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-resource-limits.html) then additional jobs aren't run until the currently running jobs have completed. This allocation strategy keeps costs lower but can limit scaling. If you are using Spot Fleets with `BEST_FIT` then the Spot Fleet IAM role must be specified.
	// - **BEST_FIT_PROGRESSIVE** - AWS Batch will select additional instance types that are large enough to meet the requirements of the jobs in the queue, with a preference for instance types with a lower cost per unit vCPU. If additional instances of the previously selected instance types aren't available, AWS Batch will select new instance types.
	// - **SPOT_CAPACITY_OPTIMIZED** - AWS Batch will select one or more instance types that are large enough to meet the requirements of the jobs in the queue, with a preference for instance types that are less likely to be interrupted. This allocation strategy is only available for Spot Instance compute resources.
	//
	// With both `BEST_FIT_PROGRESSIVE` and `SPOT_CAPACITY_OPTIMIZED` strategies, AWS Batch might need to go above `maxvCpus` to meet your capacity requirements. In this event, AWS Batch never exceeds `maxvCpus` by more than a single instance.

	// > This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
	MaxSwap *float64 `field:"optional" json:"maxSwap" yaml:"maxSwap"`
	// The value for the size (in MiB) of the `/dev/shm` volume.
	//
	// This parameter maps to the `--shm-size` option to [docker run](https://docs.aws.amazon.com/https://docs.docker.com/engine/reference/run/) .
	//
	// > This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
	SharedMemorySize *float64 `field:"optional" json:"sharedMemorySize" yaml:"sharedMemorySize"`
	// 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](https://docs.aws.amazon.com/https://docs.docker.com/engine/reference/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.
	//
	// > 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](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-store-swap-volumes.html) 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?](https://docs.aws.amazon.com/premiumsupport/knowledge-center/ec2-memory-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.
	//
	// > This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
	Swappiness *float64 `field:"optional" json:"swappiness" yaml:"swappiness"`
	// The container path, mount options, and size (in MiB) of the tmpfs mount.
	//
	// This parameter maps to the `--tmpfs` option to [docker run](https://docs.aws.amazon.com/https://docs.docker.com/engine/reference/run/) .

			order: jsii.Number(1),
		},
	},

	// 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.
	// Experimental.
