# v16 is Pacific, and v17 is Quincy.
# RECOMMENDATION: In production, use a specific version tag instead of the general v17 flag, which pulls the latest release and could result in different
# versions running within the cluster. See tags available at https://hub.docker.com/r/ceph/ceph/tags/.
# If you want to be more precise, you can always use a timestamp tag such quay.io/ceph/ceph:v17.2.6-20230410
# This tag might not contain a new Ceph version, just security fixes from the underlying operating system, which will reduce vulnerabilities
image: quay.io/ceph/ceph:v17.2.6
# Whether to allow unsupported versions of Ceph. Currently `pacific` and `quincy` are supported.

# When encryption is not enabled, clients still establish a strong initial authentication and data integrity is still validated with a crc check.
# IMPORTANT: Encryption requires the 5.11 kernel for the latest nbd and cephfs drivers. Alternatively for testing only,
# you can set the "mounter: rbd-nbd" in the rbd storage class, or "mounter: fuse" in the cephfs storage class.
# The nbd and fuse drivers are *not* recommended in production since restarting the csi driver pod will disconnect the volumes.
