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"
}
