Subject [jira] [Commented] (DTACLOUD-443) Openstack Provider 'Availability Zones'
Date Wed, 06 Feb 2013 14:11:14 GMT


Christian Karnath commented on DTACLOUD-443:

OK, I did the test drive and here are my notes:

- requesting /api/realms against openstack returns all regions which are available. I comply
with this solution.

- requesting /api/instances is only working when I specify a region within API_PROVIDER. Would
it be possible to loop through all realms when omitting a specific region? It would be very
helpful if both ways are possible.

- the realm attribute is not set correctly for a single instance and always pointing to the
‘default’ realm:
<instance href='' id='1047655'>
  <realm href='' id='default'></realm>

> Hey Marios,
> HPCloud provides three different compute clouds (availability zones) at the moment. How
can I specify which compute cloud is used with the openstack driver, because the API credentials
and the URL endpoint of the identity service (keystone) are the same. Connecting and authenticating
directly to the nova-api of a specific compute cloud is not possible, because HPCloud is using
keystone as a centralized identity management solution.
> I guess when authentication against the identity service all three compute clouds are
returned, but only the first cloud is manageable with deltacloud? Would it make sense to re-implement
/api/realms for this case? The current /api/realms implementation could be retained for users
who are connection directly to a specific nova api endpoint (i. e. an openstack environments
without keystone).
