Subject: [PATCH] Add support for hostpath persistent volume definitions
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

hostpath volumes [1] mount a file or directory from the host node’s
filesystem into a pod. This adds support for declaring a hostPath
volume as a persistent volume and do a persistent volume claim for
one for the hosted registry.
