-- | 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
-- <https://kubernetes.io/docs/concepts/storage/volumes/#emptydir emptyDir>
-- in the /Kubernetes documentation/.
