ContainerOverrides

The overrides that should be sent to a container.

command

The command to send to the container that overrides the default command from the Docker image or the job definition.

Type: Array of strings

Required: No

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.

Note

Environment variables must not start with AWS_BATCH; this naming convention is reserved for variables that are set by the AWS Batch service.

Type: Array of KeyValuePair objects

Required: No

instanceType

The instance type to use for a multi-node parallel job.

Note

This parameter isn't applicable to single-node container jobs or jobs that run on Fargate resources, and shouldn't be provided.

Type: String

Required: No

memory

This member has been deprecated.

This parameter indicates the amount of memory (in MiB) that's reserved for the job. It overrides the memory parameter set in the job definition, but doesn't override any memory requirement specified in the ResourceRequirement structure in the job definition. To override memory requirements that are specified in the ResourceRequirement structure in the job definition, ResourceRequirement must be specified in the SubmitJob request, with type set to MEMORY and value set to the new value.

This parameter is supported for jobs that run on EC2 resources, but isn't supported for jobs that run on Fargate resources. For these resources, use resourceRequirement instead.

Type: Integer

Required: No

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.

Type: Array of ResourceRequirement objects

Required: No

vcpus

This member has been deprecated.

This parameter indicates the number of vCPUs reserved for the container.It overrides the vcpus parameter that's set in the job definition, but doesn't override any vCPU requirement specified in the resourceRequirement structure in the job definition. To override vCPU requirements that are specified in the ResourceRequirement structure in the job definition, ResourceRequirement must be specified in the SubmitJob request, with type set to VCPU and value set to the new value.

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.

Note

This parameter is supported for jobs that run on EC2 resources, but isn't supported for jobs that run on Fargate resources. For Fargate resources, you can only use resourceRequirement. For EC2 resources, you can use either this parameter or resourceRequirement but not both.

Type: Integer

Required: No
