Subject RE: [DISCUSS] Dedicated Resources: Dedicate Pods, Clusters, Hosts to a domain
Date Fri, 21 Dec 2012 09:33:47 GMT
Planners and allocators work on a DeploymentPlan provided as input. The caller can specify
particular zone, pod, cluster, host, pool  etc., to be used for deployment. 
So for enforcing the use of a dedicated pod, caller can set the podId in the plan and planners
will search under the specific pod only.

There may be some changes necessary (like accepting a list of pods/clusters instead of single
Ids) but this design of planners should let you enforce the use of dedicated resources without
major changes to planners.

Hi Alex,

I assume some apis will be added for letting an admin dedicate a pod/cluster etc to a domain.
This can be contained in a plugin. However, for enforcing that a dedicated resource is picked
up for servicing deploy vm requests from a user; wouldn't planners and allocators have to
be updated to take care of this?

Regards,
Devdeep
