Re: Multiple DNS names for RGW?

It's straightforward to add multiple DNS names to an endpoint. We do this for the sort of reasons you suggest. You then don't need separate rgw instances (not for this reason anyway).

Assuming default:

 * radosgw-admin zonegroup get > zg-default
 * Edit zg-default, changing "hostnames" to e.g.  ["host1",
   "host1.domain", "host2", "host2.domain"]
 * radosgw-admin zonegroup set --infile zg-default
 * Restart all rgw instances

Hi,


we are running RGW behind haproxy for TLS termination and load balancing. Due to some major changes in our setup, we would like to start a smooth transition to a new hostname of the S3 endpoint. The haproxy part should be straightforward (adding a second frontend).


But on the RGW side it might be more complex. Let's assume that the current DNS name is example.com, and I want to transition to example.org. The example.com name is set as rgw_dns_name in the ceph configuration for that rgw instance. It is also set as a single endpoint in the active zone/zonegroup.


Is it sufficient to update the zonegroup setting and add a second endpoint for example.org? User should be able to access their bucket as bucket.example.org and bucket.example.com during the transition time.

Burkhard
