Thanks Austin. I do not use DNS, just local name resolution through hosts file. I'm not sure how i would configure resolution or http://bucket.host.

Check that DNS is set up correctly to allow http://bucket.host.tld/ instead of http://host.tld/bucket/. Or change the operation of your client to conform to the latter.

There are also a few config parameters that will need to be added to ceph.conf to allow dns bucket resolution.

Hello,

I created a test cluster of 3 OSD hosts (xen1,2,3) based on Ubuntu Xenial, ceph 10.2.1 using the quick start steps in the docs master branch.

After jumping through a few problems, mainly from the inconsistent details in the docs, i got a stable cluster running with RGW.

Running s3boto test script to create a new bucket works fine. however, when I use ay other tool to PUT files, I get a strange error stating "host not found". There is nothing in the gateway logs that would suggest why this happens, i only get the list of get requests from the cliient(s) I use.
