Common Entities

Bucket and Host Name

There are two different modes of accessing the buckets. The first (preferred) method identifies the bucket as the top-level directory in the URI.

GET /mybucket HTTP/1.1
Host: cname.domain.com

The second method identifies the bucket via a virtual bucket host name. For example:

GET / HTTP/1.1
Host: mybucket.cname.domain.com

To configure virtual hosted buckets, you can either set rgw_dns_name = cname.domain.com in ceph.conf, or add cname.domain.com to the list of hostnames in your zonegroup configuration. See Ceph Object Gateway - Multisite Configuration for more on zonegroups.

Tip

We prefer the first method, because the second method requires expensive domain certification and DNS wild cards.
