AWS::Batch::JobDefinition EksEmptyDir

Specifies the configuration of a Kubernetes emptyDir volume. An emptyDir volume is first created when a pod is assigned to a node. It exists as long as that pod is running on that node. The emptyDir volume is initially empty. All containers in the pod can read and write the files in the emptyDir volume. However, the emptyDir volume can be mounted at the same or different paths in each container. When a pod is removed from a node for any reason, the data in the emptyDir is deleted permanently. For more information, see emptyDir in the Kubernetes documentation.
