The most recent Ceph "Nautilus" release claims Kubernetes support in CephFS (not via RDB). It is not clear how to configure Kubernetes (without Rook) to get access to my CephFS cluster just like I can access NFS storage.

What I did:

1.Installed the Ceph cluster 2. Used examples from ceph-csi and wasn't able to configure pvc. Looks like I missed some steps (how to install the Ceph provisioner is not clear?). It doesn't work out of the box for me.

I used code from "ceph-csi/deploy/cephfs/kubernetes/" folder taken from GitHub.
