NFS Provisioner Role

The nfs-provisioner role will configure a Qubinode device to use NFS for OpenShift persistant storage. It configures the Kubernetes NFS-Client Provisioner and setup up the OpenShift internal registry to use a NFS backed PVC.

The nfs-provisioner configure the Qubinode as NFS server.

Requirements

This role is intended to be executed on a Qubinode.
