Notes on volume size: when provisioning a new volume, `max_bytes` quota attribute for this volume will be set to the requested volume size (see [Ceph quota documentation](http://docs.ceph.com/docs/mimic/cephfs/quota/)). A request for a zero-sized volume means no quota attribute will be set.
## Deployment with Kubernetes
Requires Kubernetes 1.11
