[ceph-users] orch apply mon assigns wrong IP address?

Is there a way to force '.. orch apply  *' to limit ip address selection to addresses matching the hostname in dns or /etc/hosts, or to a specific address given at 'host add' time?   I've hit a bothersome problem: On v15, 'ceph orch apply mon ...' appears not to use the dns ip or /etc/hosts when installing a monitor, but instead appears to select one from the current list of interfaces up on the host.  99 of 100 times this is correct as the host has but one address on the public cluster subnet.   However, this or that host might have a temporary added ip interface up on that subnet (whether for one-of diagnostic purposes or some HA assigned movable address like a time of day server).  Occasionally that second 'unlisted' address is 'up' when the orchestrator decides then would be a good time  to add a mon to that host.   Ceph somehow occasionally prefers this 'unlisted but up' interface address, using that permanently as the host address for the monitor docker image, even though that 'secondary' interface is not in DNS for the host, nor in /etc/hosts anywhere for that host.   Is this a known issue?  Is there a way to direct the orchestrator to use 'dns resolvable only' or 'preferred' addresses?
