Auto-upgrade is enabled by default for newly created clusters. The nodes are upgraded to keep up with the version of the master. The upgrade takes place during a chosen maintenance window. Only one node is upgraded at a time, and only within one node pool of the cluster. During the upgrade, the Pods residing in the node being upgraded are rescheduled. If it isn't possible to reschedule, the Pod goes into the pending mode. To enable auto-upgrade, use the --enable-autoupgrade flag when creating or updating your cluster.
