Openstack SDK with Rackspace

I used to use rackspace-novaclient, but that fell apart on me.

If you search for the official python SDK for Rackspace Cloud - you're likely to find pyrax.

But I guess by summer '15 they were full on the Openstack-SDK ride!

Openstack-SDK seems like a decent attempt to organize things.  Docs are decent.  But my first attempt to do something 401'd

In [68]: conn.authorize()
---------------------------------------------------------------------------
HttpException                             Traceback (most recent call last)
 in ()
----> 1 conn.authorize()

/private/tmp/test-os-sdk/lib/python2.7/site-packages/openstack/connection.pyc in authorize(self)
    264             raise exceptions.HttpException("Unknown exception",
    265                                            six.text_type(ex),
--> 266                                            status_code=500)
    267 
    268         return headers.get('X-Auth-Token') if headers else None

HttpException: HttpException: Unknown exception, Unauthorized (HTTP 401)

Turns out, the openstack.connection.Connection class doesn't work quite like novaclient, a few params are different.  Instead of using your API Key - you need to use your password:

from openstack import connection

conn = connection.Connection(
    auth_url='https://identity.api.rackspacecloud.com/v2.0/',
    username='username',
    password='password')  # <- NOT API KEY!!!

After that the only tricky part was setting the region:

conn.profile.set_region(conn.profile.ALL, 'IAD')
