OpenShift Quicktip: Testdriving persistent storage with NFS

Creating a persistent volume for NFS storage plugin

The administrator is responsible for creating volumes (PV). The administrator assigns some external thing (partition, entire device, NFS volume, whatever) to a PV.

1. Login to OpenShift with an admin user
2. Create persistent volume:

oc create -f persistent-volume-nfs.yaml

1. Check status of persistent volume:

oc get pv

Creating a persistent volume claim

The end-user/developer/user/whatever is responsible for making a request for a volume (PVC). They get assigned some volume, and they don’t really know what it is. Keep in mind that there is a 1:1 mapping between PV and PVCs.

1. Login to OpenShift
2. Create persistent volume claim:

oc create -f persistent-volume-claim.yaml
