Ceph » Orchestrator

A 'hostname' like sub-string could be provided as a realm/zone :

$ ceph orch apply rgw realm host1 --placement host1
Scheduled rgw.realm.host1 update...

Creating this DaemonDesription:

$ ceph orch ps --daemon-type rgw --format yaml

But breaks the `orch ls` command:

$ ceph orch ls rgw
