Overview

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.

#args ⇒ Array<String>

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][3

and [Define a command and arguments

for a pod] in the *Kubernetes documentation*.

#command ⇒ Array<String>

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*.
