Overview

Note:

When making an API call, you may pass ContainerProperties data as a hash:

{
  image: "String",
  vcpus: 1,
  memory: 1,
  command: ["String"],
  job_role_arn: "String",
  volumes: [
    {
      host: {
        source_path: "String",
      },
      name: "String",
    },
  ],
  environment: [
    {
      name: "String",
      value: "String",
    },
  ],
  mount_points: [
    {
      container_path: "String",
      read_only: false,
      source_volume: "String",
    },
  ],
  readonly_root_filesystem: false,
  privileged: false,
  ulimits: [
    {
      hard_limit: 1, # required
      name: "String", # required
      soft_limit: 1, # required
    },
  ],
  user: "String",
  instance_type: "String",
  resource_requirements: [
    {
      value: "String", # required
      type: "GPU", # required, accepts GPU
    },
  ],
  linux_parameters: {
    devices: [
      {
        host_path: "String", # required
        container_path: "String",
        permissions: ["READ"], # accepts READ, WRITE, MKNOD
      },
    ],
  },
}

Container properties are used in job definitions to describe the container that is launched as part of a job.

Instance Attribute Details

#command ⇒ Array<String>

The command that is 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.

Returns:

  • (Array<String>)

end

#environment ⇒ Array<Types::KeyValuePair>

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 do not recommend using plaintext environment variables for sensitive information, such as credential data.

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

end

#image ⇒ String

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. 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 docker run.

  • Images in Amazon ECR repositories use the full registry and repository URI (for example, 012345678910.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).

Returns:

  • (String)

#memory ⇒ Integer

The hard limit (in MiB) of memory to present to the container. If your container attempts to exceed the memory specified here, the container is killed. 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.

If you are 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.
