While mostly a workaround, could you try using volume claims?

To add to this, I have been using this module from PV/PVC within a deployment, unfortunately it only works as ReadOnly when deployed this way. If I attempt to mount it as ReadWrite the pods will fail to launch.
For me this is working within a deployment. Here is my YAML, so you can compare:
