Now an OpenStack driver for Kubernetes Cluster Autoscaler is being proposed to support autoscaling when running k8s cluster on top of OpenStack. However, currently there is no way in Magnum to let the external consumer to control which node will be removed. The alternative option is calling Heat API directly but obviously it is not the best solution and it's confusing k8s community. So with this patch, we're going to add a new API: POST <ClusterID>/actions/resize And the post body will be: { "node_count": 3, "nodes_to_remove": ["dd9cc5ed-3a2b-11e9-9233-fa163e46bcc2"], "nodegroup": "production_group" } The API will be working in a declarative way. For example, there are 3 nodes in the cluser now, user can propose an API request like above. Magnum will call Heat to remove the node dd9cc5ed-3a2b-11e9-9233-fa163e46bcc2 firstly, then bring the node count back to 3 again.
