Process to copy contents from one PVC to another

I created this to allow me to migrate from different storage backends for a given project. The process would be:

• Create a new PVC using the preferred storage backend
• Shutdown app (scale replicas to zero)
• Run sync process job
• Edit Pod specs to use new PVC
• Scale app back up

Usage

oc process -f job-template.yaml SOURCE_PVC=sourcepvc DEST_PVC=destpvc | oc create -f -
