Bug Description

Currently the only way to tell via the API if the Cinder-Backup service is configured is via the service_list command. This doesn't work for Horizon however because it's an Admin API.

Horizon typically relies on Service Catalogue entries based on "regular" user token info for this sort of thing but that doesn't work in this case either.

We should provide a user facing API that shows reduced information similar to service-list that could be consumed by Horizon an may be useful for describing some other forms of capability info to end-users.

Hi John,

I sent an email to openstack-dev-mailing list (http://lists.openstack.org/pipermail/openstack-dev/2015-October/077209.html) asking for inputs on 2 design alternatives for this problem. If you happen to see that, I would appreciate if you could reply.

Thanks,
Deepti

I would like to add yet another perspective to this bug, which is Orchestration and interoperability of orchestration templates.

In Heat we have a delete_policy: snapshot for volume resources, which creates a volume backup on volume delete. However, AFAIK cinder-backup is an optional service, and thus Heat has no way to deduce from user-scoped API requests if this is available or not in order to fail early when such template is used.

I can pick this task up again if the community still needs it. It would always be a good thing if there was an API which horizon could query to find out if backup is enabled or not. This patch basically just needs to be rebased.

Moving back to triaged given that it hasn't be touched in quite some time. Satyajeet, feel free to take it back if you are able to do so.
