02/16/2023, 5:05 AMI use this CephFS provisioner which seems to be retired
https://github.com/kubernetes-retired/external-storage/tree/master/ceph/cephfs

02/16/2023, 5:07 AMI changed my approach to as below:
• create a PV having a spec for Cephfs config (monitor, secret)
• create a PVC to claim a storage from that PV
• mount pods from that PVC

02/16/2023, 5:09 AMthis way I don't need a CephFS provisioner, but the volumes must be created manually

02/16/2023, 11:05 AMThere's a more recent CSI driver you should consider instead of that retired project
