Long: `Generate the most basic Ceph config for connecting non-Ceph daemons to a Ceph
|
|
cluster (e.g., nfs-ganesha). Effectively what this means is that it generates
|
|
'/etc/ceph/ceph.conf' with 'mon_host' populated and a keyring path (given via
|
|
commandline flag) associated with the user given via commandline flag.
|
|
'mon_host' is determined by the 'ROOK_CEPH_MON_HOST' env var present in other
|
|
Ceph daemon pods, and the keyring is expected to be mounted into the container
|
|
with a Kubernetes pod volume+mount.`,
