To enable the rolling upgrade ability of Kubernetes Cluster, this patch is proposing a new API /upgrade to support upgrade the base operating system of nodes and the version of Kubernetes, even add-ons running on the k8s cluster: POST <ClusterID>/actions/upgrade And the post body will be: { "cluster_template": 'dd9cc5ed-3a2b-11e9-9233-fa163e46bcc2', "max_batch_size": 1, "nodegroup": "production_group" } Co-Authored-By: Feilong Wang <flwang@catalyst.net.nz> Task: 30168 Story: 2002210 Change-Id: Ia168877778aa0d473383eb06b1c8a16dc06b0576
