EksContainer

EKS container properties are used in job definitions for Amazon EKS based job definitions to describe the properties for a container node in the pod that's launched as part of a job. This can't be specified for Amazon ECS based job definitions.

image

The Docker image used to start the container.

Type: String

Required: Yes

args

An array of arguments to the entrypoint. If this isn't specified, the CMD of the container image is used. This corresponds to the args member in the Entrypoint portion of the Pod in Kubernetes. Environment variable references are expanded using the container's environment.

If the referenced environment variable doesn't exist, the reference in the command isn't changed. For example, if the reference is to "$(NAME1)" and the NAME1 environment variable doesn't exist, the command string will remain "$(NAME1)." $$ is replaced with $, and the resulting string isn't expanded. For example, $$(VAR_NAME) is passed as $(VAR_NAME) whether or not the VAR_NAME environment variable exists. For more information, see Dockerfile reference: CMD and Define a command and arguments for a pod in the Kubernetes documentation.

Type: Array of strings

Required: No

command

The entrypoint for the container. This isn't run within a shell. If this isn't specified, the ENTRYPOINT of the container image is used. Environment variable references are expanded using the container's environment.

If the referenced environment variable doesn't exist, the reference in the command isn't changed. For example, if the reference is to "$(NAME1)" and the NAME1 environment variable doesn't exist, the command string will remain "$(NAME1)." $$ is replaced with $ and the resulting string isn't expanded. For example, $$(VAR_NAME) will be passed as $(VAR_NAME) whether or not the VAR_NAME environment variable exists. The entrypoint can't be updated. For more information, see ENTRYPOINT in the Dockerfile reference and Define a command and arguments for a container and Entrypoint in the Kubernetes documentation.

Type: Array of strings

Required: No

env

The environment variables to pass to a container.

Note

Environment variables cannot start with "AWS_BATCH". This naming convention is reserved for variables that AWS Batch sets.

Type: Array of EksContainerEnvironmentVariable objects

Required: No

imagePullPolicy

The image pull policy for the container. Supported values are Always, IfNotPresent, and Never. This parameter defaults to IfNotPresent. However, if the :latest tag is specified, it defaults to Always. For more information, see Updating images in the Kubernetes documentation.

name

The name of the container. If the name isn't specified, the default name "Default" is used. Each container in a pod must have a unique name.

Type: String

Required: No
