Invalid Bucket Name Error with Ceph and Swift API

[Jerome Bell]

I installed Mirantis OpenStack 7.0 with

1 Controller/Ceph Node
1 Compute/Ceph Node
1 Ceph Node
x3 replication factor

I sourced a file and executed

swift --debug list

and got the following output

Thus, it seems like I have an issue with an invalid bucket name. Given that I am simply trying to list the objects in the account I don't see how I could have an issue with a bucket name. Am I missing something here? Any help is appreciated. Thanks!

It looks that StorageURL is wrongly configured:

INFO:swiftclient:REQ: curl -i http://192.168.2.8:8080/v1/AUTH_42a6c9d5a69a4bf7a0279c329a50dbde?format=json -X GET -H "X-Auth-Token: 37bc580e8d4044438e93cbbd9f98e9e5"

radosgw doesn't support the full URL schema from Swift.
In order to list an account the supplied URL should look like
the following one:

http://192.168.2.8:8080/swift/v1

Account ID will be extracted by radosgw basing only on token
provided in X-Auth-Token HTTP header, not from the URL itself.

Is there a workaround for this issue?

[Radoslaw Zarzynski (rzarzynski)]

Pull request [1] with full support for Swift's URL schema (including account
identifier extracted from URL, not only from an auth token) has been sent.

However, it won't be available in MOS 8.0, so the appropriate status has
been changed to "Won't fix".

As a workaround skipping the account part from endpoint URL could be
employed. For example, those are URLs used in Keystone as endpoints
for radosgw as a Swift API provider:

root@node-1:~# keystone endpoint-list | grep a80b73bb22024bea81dd4ea6674dcddb
/usr/lib/python2.7/dist-packages/keystoneclient/shell.py:65: DeprecationWarning: The keystone CLI is deprecated in favor of python-openstackclient. For a Python library, continue using python-keystoneclient.
  'python-keystoneclient.', DeprecationWarning)

As can be seen the tenant/account part (denoted in Keystone by
"KEY_$(tenant_id)s") is absent.
