Chris Custine closed JCLOUDS-238.
---------------------------------
Resolution: Fixed
Fix Version/s: 1.8.0
As of 1.8.0 (fixed in issue JCLOUDS-647) you retrieve the api for a region with
getServerApi("region_name") on NovaApi. If necessary, you can specify an
availability zone with NovaTemplateOptions.availabilityZone("az3"), etc.
> api/openstack-compute supports only a per AZ deployment model

> Key: JCLOUDS-238
> URL: https://issues.apache.org/jira/browse/JCLOUDS-238
> Project: jclouds
> Issue Type: Bug
> Components: jclouds-compute
> Affects Versions: 1.6.0
> Reporter: Kavan K Patil
> Assignee: Chris Custine
> Fix For: 1.8.0
>
>
> I have been testing NovaApi against HP Cloud and have been working with both
> per AZ endpoint model and a region wide endpoint model in different regions.
> For clarity I would define the following two terms so that it helps me
> providing further details:
> Per AZ endpoint model : I call it so as we get a per AZ compute endpoint url.
> Using this URL we could only work with a particular AZ of a cloud provider
> (e.g. HP Cloud region-a has az1.region-a.geo-1 as one AZ and has its own
> compute endpoint)
> Region wide endpoint model: In this model there will be one compute endpoint
> exposed by the provider. But underneath there could be multiple AZs. All the
> openstack services work region wide and compute instances can be placed on
> all AZs within the region selectively through an option while creating
> instances. (e.g. HPCloud region-b.geo-1, which will have a single endpoint
> for compute for the entire region. This is still in private beta stage.)
> The existing framework with JClouds doesn't seem to fit the region wide model
> and below I describe 3 issues I see.
> To start with I can create a single connection for HP Cloud as below
> {code}
> -----------
> NovaApi api =
> ContextBuilder.newBuilder("hpcloud-compute")
> .credentials(identity, password)
> .modules(modules)
> .apiVersion("2") //The api version of region-b.geo-1 is 2
> which is required for next steps
> -------------
> {code}
> And the issues:
> 1. But to get a reference to the ServerApi under this region I need to give
> the name of a region, though the method name clearly expects a zone id.
> {code}
> -------------
> //So now we have a new connection to region-b-geo-1
> //But to get a ServerApi handle I need to do
> //This looks ugly, as i need to provide the name of region for a zone!
> serverApi = this.novaApi.getServerApiForZone("region-b.geo-1");
> //Ideally one should be able to do this instead of the above. But JClouds
> throws an error that an endpoint for this AZ was not found
> //serverApi = this.novaApi.getServerApiForZone("az1");
> ------------------------------
> {code}
> 2. Also now that I have a ServerApi to the region, I don't get to select an
> AZ to schedule an instance to a specific one. There is NO option under
> CreateServerOptions to specify an AZ name!
> 3. And the below call should return all AZs (az1, az2, az3), but it only
> returns region-b.geo-1
> {code}
> ---------------------
> this.novaApi.getConfiguredZones()
> ---------------------
> {code}
> I think this is due to the fact that the implementation of
> getConfiguredZones() is mapped to the endpoints in the service catalogue
> rather than the below API extension:
> {code}
> ----------------
> curl -i
> https://region-b.geo-1.compute.hpcloudsvc.com/v2/<tenant-id>/os-availability-zone
> -X GET -H "Accept: application/json" -H "X-Auth-Token: <token>"
