[openstack-ansible] Relocate ceph-mons to new hosts and decouple Ceph from openstack-ansible

Hi, We run a cluster with ~15 compute hosts and ~25 Ceph nodes. Everything was initially deployed with openstack-ansible. For some reasons we would like to decouple Ceph from openstack-ansbile and therefore move the ceph-mon containers to dedicated hosts. - Moving the containers seems straightforward, but how do we tell openstack-ansible that the containers are gone and that it can’t use the ip addresses anymore for other purposes? - How do we tell openstack-ansible which keyrings it has to deploy on compute hosts? Any recommendations? Has anyone done this before? Can you think of anything else that should be considered? Thanks in advance and best regards Jan
