clusterupdatecontroller

Documentation

Overview

Package clusterupdatecontroller contains a controller that coordinates the upgrade of clusters. It watches the cluster.Spec.Version and will initiate the controlled update of first the apiserver, then the rest of the control plane and finally nodes. It does so by manipulating the ClusterStatus, letting other controller take care of reconciling the cluster namespace or updating/watching the nodes in the user cluster.
