`Kubernetes Pods or Deployments`
Only three volume types are supported by kube play, the *hostPath*, *emptyDir*, and *persistentVolumeClaim* volume types.
Only four volume types are supported by kube play, the *hostPath*, *emptyDir*, *persistentVolumeClaim*, and *image* volume types.
- When using the *hostPath* volume type, only the *default (empty)*, *DirectoryOrCreate*, *Directory*, *FileOrCreate*, *File*, *Socket*, *CharDevice* and *BlockDevice* subtypes are supported. Podman interprets the value of *hostPath* *path* as a file path when it contains at least one forward slash, otherwise Podman treats the value as the name of a named volume.
- When using a *persistentVolumeClaim*, the value for *claimName* is the name for the Podman named volume.
- When using an *emptyDir* volume, Podman creates an anonymous volume that is attached the containers running inside the pod and is deleted once the pod is removed.
- When using an *image* volume, Podman creates a read-only image volume with an empty subpath (the whole image is mounted). The image must already exist locally. It is supported in rootful mode only.
Note: The default restart policy for containers is `always`. You can change the default by setting the `restartPolicy` field in the spec.

An image can be automatically mounted into a container if the annotation `io.podman.annotations.kube.image.automount/$ctrname` is given. The following rules apply:
