RUNNING status.
List<E> networkInterfaces
The network interfaces that are associated with the job attempt.
AttemptContainerDetail container
The details for the container in this job attempt.
Long startedAt
The Unix timestamp (in milliseconds) for when the attempt was started (when the attempt transitioned from the
STARTING state to the RUNNING state).
Long stoppedAt
The Unix timestamp (in milliseconds) for when the attempt was stopped (when the attempt transitioned from the
RUNNING state to a terminal state, such as SUCCEEDED or FAILED).
String statusReason
A short, human-readable string to provide additional details for the current status of the job attempt.
List<E> taskProperties
The properties for a task definition that describes the container and volume definitions of an Amazon ECS task.

String ecsClusterArn
The Amazon Resource Name (ARN) of the underlying Amazon ECS cluster that the compute environment uses.
Map<K,V> tags
The tags applied to the compute environment.
String type
The type of the compute environment: MANAGED or UNMANAGED. For more information, see Compute environments in
the Batch User Guide.
String state
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.
String status
The current status of the compute environment (for example, CREATING or VALID).

compute environments are associated with a job queue, the compute environment with a lower order
integer value is tried for job placement first.
String computeEnvironment
The Amazon Resource Name (ARN) of the compute environment.
String type
The type of compute environment: EC2, SPOT, FARGATE, or
FARGATE_SPOT. For more information, see Compute environments in
the Batch User Guide.
If you choose SPOT, you must also specify an Amazon EC2 Spot Fleet role with the
spotIamFleetRole parameter. For more information, see Amazon EC2 spot fleet role
in the Batch User Guide.
String allocationStrategy
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.
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.
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.
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.
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.
Integer minvCpus
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.
Integer maxvCpus
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.
Integer desiredvCpus
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.
List<E> instanceTypes
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.
String imageId
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.

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.

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.
Map<K,V> tags
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.
String placementGroup
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.
Integer bidPercentage
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.
String spotIamFleetRole
The Amazon Resource Name (ARN) of the Amazon EC2 Spot Fleet IAM role applied to a SPOT compute
environment. This role is required if the allocation strategy set to BEST_FIT or if the allocation
strategy isn't specified. For more information, see Amazon EC2 spot fleet role
in the Batch User Guide.
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.
LaunchTemplateSpecification launchTemplate
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.
List<E> ec2Configuration
Provides information that's used to select Amazon Machine Images (AMIs) for Amazon EC2 instances in the compute

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.
Batch doesn't support changing the desired number of vCPUs of an existing compute environment. Don't specify this parameter for compute environments using Amazon EKS clusters.
When you update the desiredvCpus setting, the value must be between the minvCpus and
maxvCpus values.
Additionally, the updated desiredvCpus value must be greater than or equal to the current
desiredvCpus value. For more information, see Troubleshooting Batch in the Batch User Guide.
List<E> subnets
The VPC subnets where the compute resources are launched. Fargate compute resources can contain up to 16 subnets. For Fargate compute resources, providing an empty list will be handled as if this parameter wasn't specified and no change is made. 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.

in both the vcpus and resourceRequirements object. This parameter maps to
CpuShares in the Create a
container section of the Docker Remote API and the
--cpu-shares option to docker run. Each
vCPU is equivalent to 1,024 CPU shares. You must specify at least one vCPU. This is required but can be specified
in several places. It must be specified for each node at least once.
This parameter isn't applicable to jobs that run on Fargate resources. For jobs that run on Fargate resources,
you must specify the vCPU requirement for the job using resourceRequirements.
Integer memory

LogConfiguration logConfiguration
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option
to docker run. By default, containers use the same
logging driver that the Docker daemon uses. However, the container might use a different logging driver than the
Docker daemon by specifying a log driver with this parameter in the container definition. To use a different
logging driver for a container, the log system must be configured properly on the container instance. Or,
alternatively, it must be configured on a different log server for remote logging options. For more information
on the options for different supported log drivers, see Configure logging drivers in the Docker
documentation.
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

RuntimePlatform runtimePlatform
An object that represents the compute environment architecture for Batch jobs on Fargate.
RepositoryCredentials repositoryCredentials
The private repository authentication credentials to use.
Integer vcpus
This parameter is deprecated, use resourceRequirements to override the vcpus parameter
that's set in the job definition. It's not supported for jobs running on Fargate resources. For jobs that run on
Amazon EC2 resources, it overrides the vcpus parameter set in the job definition, but doesn't
override any vCPU requirement specified in the resourceRequirements structure in the job definition.
To override vCPU requirements that are specified in the resourceRequirements structure in the job
definition, resourceRequirements must be specified in the SubmitJob request, with
type set to VCPU and value set to the new value. For more information, see
Can't override job definition resource requirements in the Batch User Guide.
Integer memory
This parameter is deprecated, use resourceRequirements to override the memory requirements specified
in the job definition. It's not supported for jobs running on Fargate resources. For jobs that run on Amazon EC2
resources, it overrides the memory parameter set in the job definition, but doesn't override any
memory requirement that's specified in the resourceRequirements structure in the job definition. To
override memory requirements that are specified in the resourceRequirements structure in the job
definition, resourceRequirements must be specified in the SubmitJob request, with
type set to MEMORY and value set to the new value. For more information,
see Can't override job definition resource requirements in the Batch User Guide.
List<E> command
The command to send to the container that overrides the default command from the Docker image or the job definition.

The instance type to use for a multi-node parallel job.
This parameter isn't applicable to single-node container jobs or jobs that run on Fargate resources, and shouldn't be provided.
List<E> environment
The environment variables to send to the container. You can add new environment variables, which are added to the container at launch, or you can override the existing environment variables from the Docker image or the job definition.
Environment variables cannot start with "AWS_BATCH". This naming convention is reserved for
variables that Batch sets.
List<E> resourceRequirements
The type and amount of resources to assign to a container. This overrides the settings in the job definition. The
supported resources include GPU, MEMORY, and VCPU.
String image
Required. The image used to start a container. This string is passed directly to the Docker daemon. Images in the
Docker Hub registry are available by default. Other repositories are specified with
repository-url/image:tag . It can be 255 characters long. It can contain
uppercase and lowercase letters, numbers, hyphens (-), underscores (_), colons (:), periods (.), forward slashes
(/), and number signs (#). This parameter maps to Image in the Create a container section of the Docker Remote API and the IMAGE parameter of docker run.
Docker image architecture must match the processor architecture of the compute resources that they're scheduled on. For example, ARM-based Docker images can only run on ARM-based compute resources.
Images in Amazon ECR Public repositories use the full registry/repository[:tag] or
registry/repository[@digest] naming conventions. For example,
public.ecr.aws/registry_alias/my-web-app:latest .
Images in Amazon ECR repositories use the full registry and repository URI (for example,
123456789012.dkr.ecr.<region-name>.amazonaws.com/<repository-name>).
Images in official repositories on Docker Hub use a single name (for example, ubuntu or
mongo).
Images in other repositories on Docker Hub are qualified with an organization name (for example,
amazon/amazon-ecs-agent).
Images in other online repositories are qualified further by a domain name (for example,
quay.io/assemblyline/ubuntu).
Integer vcpus
This parameter is deprecated, use resourceRequirements to specify the vCPU requirements for the job
definition. It's not supported for jobs running on Fargate resources. For jobs running on Amazon EC2 resources,
it specifies the number of vCPUs reserved for the job.
Each vCPU is equivalent to 1,024 CPU shares. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option
to docker run. The number of vCPUs must be specified
but can be specified in several places. You must specify it at least once for each node.
Integer memory
This parameter is deprecated, use resourceRequirements to specify the memory requirements for the
job definition. It's not supported for jobs running on Fargate resources. For jobs that run on Amazon EC2
resources, it specifies the memory hard limit (in MiB) for a container. If your container attempts to exceed the
specified number, it's terminated. You must specify at least 4 MiB of memory for a job using this parameter. The
memory hard limit can be specified in several places. It must be specified for each node at least once.
List<E> command
The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to
docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd.
String jobRoleArn
The Amazon Resource Name (ARN) of the IAM role that the container can assume for Amazon Web Services permissions. For more information, see IAM roles for tasks in the Amazon Elastic Container Service Developer Guide.
String executionRoleArn

List<E> volumes
A list of data volumes used in a job.
List<E> environment
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.
Environment variables cannot start with "AWS_BATCH". This naming convention is reserved for
variables that Batch sets.
List<E> mountPoints
The mount points for data volumes in your container. This parameter maps to Volumes in the Create a container section of the Docker Remote API and the --volume option to docker run.
Boolean readonlyRootFilesystem
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.
Boolean privileged
When this parameter is true, the container is given elevated permissions on the host container instance (similar
to the root user). This parameter maps to Privileged in the Create a container section of the Docker Remote API and the --privileged option
to docker run. The default value is false.
This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided, or specified as false.
List<E> ulimits
A list of ulimits to set in the container. This parameter maps to Ulimits in the Create a container section of the Docker Remote API and the --ulimit option to docker run.
This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
String user
The user name 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.
String instanceType

This parameter isn't applicable to single-node container jobs or jobs that run on Fargate resources, and shouldn't be provided.
List<E> resourceRequirements
The type and amount of resources to assign to a container. The supported resources include GPU,
MEMORY, and VCPU.
LinuxParameters linuxParameters
Linux-specific modifications that are applied to the container, such as details for device mappings.
LogConfiguration logConfiguration
The log configuration specification for the container.
This parameter maps to LogConfig in the Create a container section of the Docker Remote API and the --log-driver option
to docker run. By default, containers use the same
logging driver that the Docker daemon uses. However the container might use a different logging driver than the
Docker daemon by specifying a log driver with this parameter in the container definition. To use a different
logging driver for a container, the log system must be configured properly on the container instance (or on a
different log server for remote logging options). For more information on the options for different supported log
drivers, see Configure logging drivers in
the Docker documentation.
Batch currently supports a subset of the logging drivers available to the Docker daemon (shown in the LogConfiguration data type).
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the
Docker Remote API version on your container instance, log 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.
List<E> secrets
The secrets for the container. For more information, see Specifying sensitive data in the Batch User Guide.
NetworkConfiguration networkConfiguration
The network configuration for jobs that are running on Fargate resources. Jobs that are running on Amazon EC2 resources must not specify this parameter.
FargatePlatformConfiguration fargatePlatformConfiguration
The platform configuration for jobs that are running on Fargate resources. Jobs that are running on Amazon EC2 resources must not specify this parameter.
EphemeralStorage ephemeralStorage
The amount of ephemeral storage to allocate for the task. This parameter is used to expand the total amount of ephemeral storage available, beyond the default amount, for tasks hosted on Fargate.
RuntimePlatform runtimePlatform
An object that represents the compute environment architecture for Batch jobs on Fargate.
RepositoryCredentials repositoryCredentials
The private repository authentication credentials to use.
String computeEnvironmentName
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 (_).
String type
The type of the compute environment: MANAGED or UNMANAGED. For more information, see Compute Environments in
the Batch User Guide.
String state
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.
Integer unmanagedvCpus
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.
ComputeResource computeResources
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.
String serviceRole
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.
Map<K,V> tags
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.
EksConfiguration eksConfiguration

String jobQueueName
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 (_).
String state
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.
String schedulingPolicyArn
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.
Integer priority
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.
List<E> computeEnvironmentOrder
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.
Map<K,V> tags
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.

Integer maxResults
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.

If the imageIdOverride parameter isn't specified, then a recent Amazon
ECS-optimized Amazon Linux 2 AMI (ECS_AL2) is used. If a new image type is specified in an
update, but neither an imageId nor a imageIdOverride parameter is specified, then the
latest Amazon ECS optimized AMI for that image type that's supported by Batch is used.
Amazon Linux 2: Default for all non-GPU instance families.
Amazon Linux
2 (GPU): Default for all GPU instance families (for example P4 and G4) and can be
used for all non Amazon Web Services Graviton-based instance types.
Amazon Linux 2023: Batch supports Amazon Linux 2023.

can be used for all non Amazon Web Services Graviton-based instance types.
String imageIdOverride
The AMI ID used for instances launched in the compute environment that match the image type. This setting
overrides the imageId set in the computeResource object.
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.

String ipcMode
The IPC resource namespace to use for the containers in the task. The valid values are host,
task, or none.
If host is specified, all containers within the tasks that specified the host IPC mode
on the same container instance share the same IPC resources with the host Amazon EC2 instance.
If task is specified, all containers within the specified task share the same IPC
resources.
If none is specified, the IPC resources within the containers of a task are private, and are not

EFS access points in the Batch User Guide. EFS IAM authorization requires that
TransitEncryption be ENABLED and that a JobRoleArn is specified.
String fileSystemId
The Amazon EFS file system ID to use.
String rootDirectory
The directory within the Amazon EFS file system to mount as the root directory inside the host. If this parameter
is omitted, the root of the Amazon EFS volume is used instead. Specifying / has the same effect as
omitting this parameter. The maximum length is 4,096 characters.
If an EFS access point is specified in the authorizationConfig, the root directory parameter must
either be omitted or set to /, which enforces the path set on the Amazon EFS access point.
String transitEncryption
Determines whether to enable encryption for Amazon EFS data in transit between the Amazon ECS host and the Amazon
EFS server. Transit encryption must be enabled if Amazon EFS IAM authorization is used. If this parameter is
omitted, the default value of DISABLED is used. For more information, see Encrypting data in transit in the
Amazon Elastic File System User Guide.
Integer transitEncryptionPort
The port to use when sending encrypted data between the Amazon ECS host and the Amazon EFS server. If you don't specify a transit encryption port, it uses the port selection strategy that the Amazon EFS mount helper uses. The value must be between 0 and 65,535.

this time passes, Batch terminates your jobs if they aren't finished. The minimum value for the timeout is 60
seconds.
For array jobs, the timeout applies to the child jobs, not to the parent array job.
For multi-node parallel (MNP) jobs, the timeout applies to the whole job, not to the individual nodes.
String launchTemplateId
The ID of the launch template.
String launchTemplateName
The name of the launch template.
String version
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.
List<E> devices
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.
Boolean initProcessEnabled
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"
Integer sharedMemorySize
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.
List<E> tmpfs
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.
Integer maxSwap
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.
Integer swappiness
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.
String jobQueue
The name or full Amazon Resource Name (ARN) of the job queue used to list jobs.
String arrayJobId
The job ID for an array job. Specifying an array job ID with this parameter lists all child jobs from within the specified array.
String multiNodeJobId
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.
String jobStatus
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.
Integer maxResults
The maximum number of results returned by ListJobs in paginated output. When this parameter is used,
ListJobs 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
ListJobs request with the returned nextToken value. This value can be between 1 and
100. If this parameter isn't used, then ListJobs returns up to 100 results and a
nextToken value if applicable.
String nextToken
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.
List<E> filters
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.
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.
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.
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.
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.
List<E> jobSummaryList
A list of job summaries that match the request.
String nextToken
The nextToken value to include in a future ListJobs request. When the results of a
ListJobs 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.
Integer maxResults
The maximum number of results that's returned by ListSchedulingPolicies in paginated output. When
this parameter is used, ListSchedulingPolicies only returns maxResults results in a
single page and a nextToken response element. You can see the remaining results of the initial
request by sending another ListSchedulingPolicies request with the returned nextToken
value. This value can be between 1 and 100. If this parameter isn't used, ListSchedulingPolicies
returns up to 100 results and a nextToken value if applicable.
String nextToken
The nextToken value that's returned from a previous paginated ListSchedulingPolicies
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.
List<E> schedulingPolicies
A list of scheduling policies that match the request.
String nextToken
The nextToken value to include in a future ListSchedulingPolicies request. When the
results of a ListSchedulingPolicies 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.
String resourceArn
The Amazon Resource Name (ARN) that identifies the resource that tags are listed for. Batch resources that support tags are compute environments, jobs, job definitions, job queues, and scheduling policies. ARNs for child jobs of array and multi-node parallel (MNP) jobs aren't supported.
String logDriver
The log driver to use for the container. The valid values that are listed for this parameter are log drivers that the Amazon ECS container agent can communicate with by default.
The supported log drivers are awslogs, fluentd, gelf,
json-file, journald, logentries, syslog, and
splunk.
Jobs that are running on Fargate resources are restricted to the awslogs and splunk log
drivers.
Specifies the Amazon CloudWatch Logs logging driver. For more information, see Using the awslogs log driver in the Batch User Guide and Amazon CloudWatch Logs logging driver in the Docker documentation.
Specifies the Fluentd logging driver. For more information including usage and options, see Fluentd logging driver in the Docker documentation.
Specifies the Graylog Extended Format (GELF) logging driver. For more information including usage and options, see Graylog Extended Format logging driver in the Docker documentation.
Specifies the journald logging driver. For more information including usage and options, see Journald logging driver in the Docker documentation.
Specifies the JSON file logging driver. For more information including usage and options, see JSON File logging driver in the Docker documentation.
Specifies the Splunk logging driver. For more information including usage and options, see Splunk logging driver in the Docker documentation.
Specifies the syslog logging driver. For more information including usage and options, see Syslog logging driver in the Docker documentation.
If you have a custom driver that's not listed earlier that you want to work with the Amazon ECS container agent, you can fork the Amazon ECS container agent project that's available on GitHub and customize it to work with that driver. We encourage you to submit pull requests for changes that you want to have included. However, Amazon Web Services doesn't currently support running modified copies of this software.
This parameter requires version 1.18 of the Docker Remote API or greater on your container instance. To check the
Docker Remote API version on your container instance, log in to your container instance and run the following
command: sudo docker version | grep "Server API version"
Map<K,V> options
The configuration options to send to the log driver. This parameter requires version 1.19 of the Docker Remote
API or greater on your container instance. To check the Docker Remote API version on your container instance, log

can write to the volume. The default value is false.
String sourceVolume
The name of the volume to mount.
String assignPublicIp
Indicates whether the job has a public IP address. For a job that's running on Fargate resources in a private
subnet to send outbound traffic to the internet (for example, to pull container images), the private subnet
requires a NAT gateway be attached to route requests to the internet. For more information, see Amazon ECS task
networking in the Amazon Elastic Container Service Developer Guide. The default value is "
DISABLED".
Integer nodeIndex

: or n:.
The lower boundary of the node range that's specified in the job definition must be fewer than the number of nodes specified in the override.
The main node index that's specified in the job definition must be fewer than the number of nodes specified in the override.
List<E> nodePropertyOverrides
The node property overrides for the job.
Integer numNodes

Integer nodeIndex
The node index for the node. Node index numbering begins at zero. This index is also available on the node with
the AWS_BATCH_JOB_NODE_INDEX environment variable.
String targetNodes
The range of nodes, using node index values, that's used to override. A range of 0:3 indicates nodes
with index values of 0 through 3. If the starting range value is omitted (
:n), then 0 is used to start the range. If the ending range value is omitted (
n:), then the highest possible node index is used to end the range.
ContainerOverrides containerOverrides
The overrides that are sent to a node range.
EcsPropertiesOverride ecsPropertiesOverride
An object that contains the properties that you want to replace for the existing Amazon ECS resources of a job.
List<E> instanceTypes
An object that contains the instance types that you want to replace for the existing resources of a job.
String targetNodes
The range of nodes, using node index values. A range of 0:3 indicates nodes with index values of
0 through 3. If the starting range value is omitted (:n), then
0 is used to start the range. If the ending range value is omitted (n:), then the
highest possible node index is used to end the range. Your accumulative node ranges must account for all nodes (
0:n). You can nest node ranges (for example, 0:10 and 4:5). In this case,
the 4:5 range properties override the 0:10 properties.
ContainerProperties container
The container details for the node range.
List<E> instanceTypes

This parameter isn't applicable to jobs that are running on Fargate resources.
In addition, this list object is currently limited to one element.
EcsProperties ecsProperties
This is an object that represents the properties of the node range for a multi-node parallel job.
String jobDefinitionName
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 (_).
String type
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.
Map<K,V> parameters
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.
Integer schedulingPriority
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.
ContainerProperties containerProperties
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.
NodeProperties nodeProperties
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.
RetryStrategy retryStrategy
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.
Boolean propagateTags
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.
JobTimeout timeout
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.
Map<K,V> tags
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.

String credentialsParameter
The Amazon Resource Name (ARN) of the secret containing the private repository credentials.
String value
The quantity of the specified resource to reserve for the container. The values vary based on the
type specified.
The number of physical GPUs to reserve for the container. Make sure that the number of GPUs reserved for all containers in a job doesn't exceed the number of available GPUs on the compute resource that the job is launched on.
GPUs aren't available for jobs that are running on Fargate resources.
The memory hard limit (in MiB) present to the container. This parameter is supported for jobs that are running on
Amazon EC2 resources. If your container attempts to exceed the memory specified, the container is terminated.
This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run. You must specify at least 4 MiB of memory
for a job. This is required but can be specified in several places for multi-node parallel (MNP) jobs. It must be
specified for each node at least once. This parameter maps to Memory in the Create a container section of the Docker Remote API and the --memory option to docker run.
If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory management in the Batch User Guide.
For jobs that are running on Fargate resources, then value is the hard limit (in MiB), and must
match one of the supported values and the VCPU values must be one of the values supported for that
memory value.
VCPU = 0.25
VCPU = 0.25 or 0.5
VCPU = 0.25, 0.5, or 1
VCPU = 0.5, or 1
VCPU = 0.5, 1, or 2
VCPU = 1 or 2
VCPU = 1, 2, or 4
VCPU = 2 or 4
VCPU = 2, 4, or 8
VCPU = 4
VCPU = 4 or 8
VCPU = 8
VCPU = 8 or 16
VCPU = 16
The number of vCPUs reserved for the container. This parameter maps to CpuShares in the Create a container section of the Docker Remote API and the --cpu-shares option
to docker run. Each vCPU is equivalent to 1,024 CPU
shares. For Amazon EC2 resources, you must specify at least one vCPU. This is required but can be specified in
several places; it must be specified for each node at least once.
The default for the Fargate On-Demand vCPU resource count quota is 6 vCPUs. For more information about Fargate quotas, see Fargate quotas in the Amazon Web Services General Reference.
For jobs that are running on Fargate resources, then value must match one of the supported values
and the MEMORY values must be one of the values supported for that VCPU value. The
supported values are 0.25, 0.5, 1, 2, 4, 8, and 16
MEMORY = 512, 1024, or 2048
MEMORY = 1024, 2048, 3072, or 4096
MEMORY = 2048, 3072, 4096, 5120, 6144, 7168, or 8192
MEMORY = 4096, 5120, 6144, 7168, 8192, 9216, 10240, 11264, 12288, 13312, 14336, 15360, or 16384
MEMORY = 8192, 9216, 10240, 11264, 12288, 13312, 14336, 15360, 16384, 17408, 18432, 19456, 20480,
21504, 22528, 23552, 24576, 25600, 26624, 27648, 28672, 29696, or 30720

String type
The type of resource to assign to a container. The supported resources include GPU,
MEMORY, and VCPU.
Integer attempts
The number of times to move a job to the RUNNABLE status. You can specify between 1 and 10 attempts.
If the value of attempts is greater than one, the job is retried on failure the same number of
attempts as the value.
List<E> evaluateOnExit
Array of up to 5 objects that specify the conditions where jobs are retried or failed. If this parameter is
specified, then the attempts parameter must also be specified. If none of the listed conditions
match, then the job is retried.
String operatingSystemFamily
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.
String cpuArchitecture
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.
String name
The name of the scheduling policy.
String arn
The Amazon Resource Name (ARN) of the scheduling policy. An example is
arn:aws:batch:us-east-1:123456789012:scheduling-policy/HighPriority .
FairsharePolicy fairsharePolicy
The fair share policy for the scheduling policy.
Map<K,V> tags
The tags that you apply to the scheduling policy to 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.
String arn
Amazon Resource Name (ARN) of the scheduling policy.
String name
The name of the secret.
String valueFrom
The secret to expose to the container. The supported values are either the full Amazon Resource Name (ARN) of the Secrets Manager secret or the full ARN of the parameter in the Amazon Web Services Systems Manager Parameter Store.
If the Amazon Web Services Systems Manager Parameter Store parameter exists in the same Region as the job you're launching, then you can use either the full Amazon Resource Name (ARN) or name of the parameter. If the parameter exists in a different Region, then the full ARN must be specified.
String shareIdentifier
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 (*).
Float weightFactor
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.
String jobName
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 (_).
String jobQueue
The job queue where the job is submitted. You can specify either the name or the Amazon Resource Name (ARN) of the queue.
String shareIdentifier
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 (*).
Integer schedulingPriorityOverride
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.
ArrayProperties arrayProperties
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.
List<E> dependsOn
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.
String jobDefinition
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.
Map<K,V> parameters
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.
ContainerOverrides containerOverrides
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.
NodeOverrides nodeOverrides
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.
RetryStrategy retryStrategy
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.
Boolean propagateTags
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.
JobTimeout timeout
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.
Map<K,V> tags
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.
EksPropertiesOverride eksPropertiesOverride
An object, with properties that override defaults for the job definition, can only be specified for jobs that are run on Amazon EKS resources.
EcsPropertiesOverride ecsPropertiesOverride
An object, with properties that override defaults for the job definition, can only be specified for jobs that are run on Amazon ECS resources.
String resourceArn
The Amazon Resource Name (ARN) of the resource that tags are added to. Batch resources that support tags are compute environments, jobs, job definitions, job queues, and scheduling policies. ARNs for child jobs of array and multi-node parallel (MNP) jobs aren't supported.
Map<K,V> tags
The tags that you apply to the resource 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.
String containerName
A unique identifier for the container.
String condition
The dependency condition of the container. The following are the available conditions and their behavior:
START - This condition emulates the behavior of links and volumes today. It validates that a
dependent container is started before permitting other containers to start.
COMPLETE - This condition validates that a dependent container runs to completion (exits) before
permitting other containers to start. This can be useful for nonessential containers that run a script and then
exit. This condition can't be set on an essential container.
SUCCESS - This condition is the same as COMPLETE, but it also requires that the
container exits with a zero status. This condition can't be set on an essential container.
List<E> command
The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to
docker run. For more information, see https://docs.docker.com/engine/reference/builder/#cmd.
List<E> dependsOn
A list of containers that this container depends on.
List<E> environment
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.
Boolean essential
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.
String image
The image used to start a container. This string is passed directly to the Docker daemon. By default, images in
the Docker Hub registry are available. Other repositories are specified with either
repository-url/image:tag or repository-url/image@digest. Up to 255 letters (uppercase
and lowercase), numbers, hyphens, underscores, colons, periods, forward slashes, and number signs are allowed.
This parameter maps to Image in the Create a container section of the
Docker Remote API and the IMAGE parameter of
the docker run .
LinuxParameters linuxParameters
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 logConfiguration
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.
List<E> mountPoints
The mount points for data volumes in your container.
This parameter maps to Volumes in the Create a container section of the
Docker Remote API and the --volume option
to docker run.
Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows
containers can't mount directories on a different drive, and mount point can't be across drives.
String name
The name of a container.
Boolean privileged
When this parameter is true, the container is given elevated privileges on the host container
instance (similar to the root user). This parameter maps to Privileged in the Create a container section of the
Docker Remote API and the --privileged
option to docker run.
This parameter is not supported for Windows containers or tasks run on Fargate.
Boolean readonlyRootFilesystem
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.
RepositoryCredentials repositoryCredentials
The private repository authentication credentials to use.
List<E> resourceRequirements
The type and amount of a resource to assign to a container. The only supported resource is a GPU.
List<E> secrets
The secrets to pass to the container. For more information, see Specifying Sensitive Data in the Amazon Elastic Container Service Developer Guide.
List<E> ulimits
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.
String user
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
uid:group
This parameter is not supported for Windows containers.
Integer exitCode
The exit code returned upon completion.
String reason
A short (255 max characters) human-readable string to provide additional details for a running or stopped container.
String logStreamName
The name of the CloudWatch Logs log stream that's associated with the container. The log group for Batch jobs is

List<E> command
The command to send to the container that overrides the default command from the Docker image or the job definition.
This parameter can't contain an empty string.
List<E> environment
The environment variables to send to the container. You can add new environment variables, which are added to the container at launch, or you can override the existing environment variables from the Docker image or the job definition.
Environment variables cannot start with AWS_BATCH. This naming convention is reserved for variables
that Batch sets.
String name
A pointer to the container that you want to override. The container's name provides a unique identifier for the container being used.
List<E> resourceRequirements
The type and amount of resources to assign to a container. This overrides the settings in the job definition. The
supported resources include GPU, MEMORY, and VCPU.
List<E> command
The command that's passed to the container. This parameter maps to Cmd in the Create a container section of the Docker Remote API and the COMMAND parameter to
docker run. For more information, see Dockerfile reference: CMD.
List<E> dependsOn
A list of containers that this container depends on.
List<E> environment
The environment variables to pass to a container. This parameter maps to Env inthe Create a container section of the Docker Remote API and the --env parameter to docker run.
We don't recommend using plaintext environment variables for sensitive information, such as credential data.
Environment variables cannot start with AWS_BATCH. This naming convention is reserved for variables
that Batch sets.

nice | nofile | nproc | rss | rtprio |
rttime | sigpending | stack.
Integer softLimit
The soft limit for the ulimit type.
String resourceArn
The Amazon Resource Name (ARN) of the resource from which to delete tags. Batch resources that support tags are compute environments, jobs, job definitions, job queues, and scheduling policies. ARNs for child jobs of array and multi-node parallel (MNP) jobs aren't supported.
List<E> tagKeys
The keys of the tags to be removed.
String computeEnvironment
The name or full Amazon Resource Name (ARN) of the compute environment to update.
String state
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.
Integer unmanagedvCpus
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.
ComputeResourceUpdate computeResources
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.
String serviceRole
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.
UpdatePolicy updatePolicy
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.
String computeEnvironmentName
The name of the compute environment. It can be up to 128 characters long. It can contain uppercase and lowercase letters, numbers, hyphens (-), and underscores (_).
String computeEnvironmentArn
The Amazon Resource Name (ARN) of the compute environment.
String jobQueue
The name or the Amazon Resource Name (ARN) of the job queue.
String state
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.
String schedulingPolicyArn
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.
Integer priority
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.
List<E> computeEnvironmentOrder
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.
List<E> jobStateTimeLimitActions
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.
Boolean terminateJobsOnUpdate
Specifies whether jobs are automatically terminated when the computer environment infrastructure is updated. The
default value is false.
Long jobExecutionTimeoutMinutes
Specifies the job timeout (in minutes) when the compute environment infrastructure is updated. The default value is 30.
String arn
The Amazon Resource Name (ARN) of the scheduling policy to update.
FairsharePolicy fairsharePolicy
The fair share policy.
Host host
The contents of the host parameter determine whether your data volume persists on the host container
instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for
your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it
stop running.
This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
String name
The name of the volume. It can be up to 255 characters long. It can contain uppercase and lowercase letters,
numbers, hyphens (-), and underscores (_). This name is referenced in the sourceVolume parameter of
container definition mountPoints.
EFSVolumeConfiguration efsVolumeConfiguration
This parameter is specified when you're using an Amazon Elastic File System file system for job storage. Jobs
that are running on Fargate resources must specify a platformVersion of at least 1.4.0.
