AWS::Batch::JobDefinition EksContainerResourceRequirements

The type and amount of resources to assign to a container. The supported resources include memory, cpu, and nvidia.com/gpu. For more information, see Resource management for pods and containers in the Kubernetes documentation.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "Limits" : Json,
  "Requests" : Json
}

YAML

  Limits: Json
  Requests: Json

Properties

Limits

The type and quantity of the resources to reserve for the container. The values vary based on the name that's specified. Resources can be requested using either the limits or the requests objects.

memory

The memory hard limit (in MiB) for the container, using whole integers, with a "Mi" suffix. If your container attempts to exceed the memory specified, the container is terminated. You must specify at least 4 MiB of memory for a job. memory can be specified in limits, requests, or both. If memory is specified in both places, then the value that's specified in limits must be equal to the value that's specified in requests.

Note

To maximize your resource utilization, provide your jobs with as much memory as possible for the specific instance type that you are using. To learn how, see Memory management in the AWS Batch User Guide.

cpu

The number of CPUs that's reserved for the container. Values must be an even multiple of 0.25. cpu can be specified in limits, requests, or both. If cpu is specified in both places, then the value that's specified in limits must be at least as large as the value that's specified in requests.

nvidia.com/gpu

The number of GPUs that's reserved for the container. Values must be a whole integer. memory can be specified in limits, requests, or both. If memory is specified in both places, then the value that's specified in limits must be equal to the value that's specified in requests.

Required: No

Type: Json

Update requires: No interruption

Requests

The type and quantity of the resources to request for the container. The values vary based on the name that's specified. Resources can be requested by using either the limits or the requests objects.

memory

The memory hard limit (in MiB) for the container, using whole integers, with a "Mi" suffix. If your container attempts to exceed the memory specified, the container is terminated. You must specify at least 4 MiB of memory for a job. memory can be specified in limits, requests, or both. If memory is specified in both, then the value that's specified in limits must be equal to the value that's specified in requests.

Note

If you're trying to maximize your resource utilization by providing your jobs as much memory as possible for a particular instance type, see Memory management in the AWS Batch User Guide.

cpu

The number of CPUs that are reserved for the container. Values must be an even multiple of 0.25. cpu can be specified in limits, requests, or both. If cpu is specified in both, then the value that's specified in limits must be at least as large as the value that's specified in requests.

nvidia.com/gpu

The number of GPUs that are reserved for the container. Values must be a whole integer. nvidia.com/gpu can be specified in limits, requests, or both. If nvidia.com/gpu is specified in both, then the value that's specified in limits must be equal to the value that's specified in requests.

Required: No
