I am trying to manually create a radosgw instance for a small development installation. I was able to muddle through and get a working mon, mgr, and osd (x2), but the docs for radosgw are based on ceph-deploy which is not part of the octopus release. The host systems are all lxc/lxd containers with centos 7 and the http://download.ceph.com/rpm-octopus/el7/$basearch repos. The radosgw setip that I did was essentially creating a keyring following the steps in https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/1.2.3/htm... as far as I could, but I have to admit that even after getting mon, mgr, and a couple of osds working I still don't grok the keyring usage... is there a more conceptual doc that explains how they are used and what has to be on each host? ** start rgw0 (systemctl start ceph-radosgw@rgw0) ** The failure on rgw0 host (journalctl -f -u ceph-radosgw@rgw0.service) Apr 27 17:00:20 rgw0 systemd[1]: Started Ceph rados gateway.
