Kubernetes Auto Upgrade
Feature state: stableAME Kubernetes Cluster Auto upgrade
What is auto upgrade
With auto upgrade enabled, AME upgrades your cluster to the latest version of its update channel without you having to start the upgrade. AME only starts an auto upgrade inside the window of the cluster's upgrade schedule, a maintenance schedule that your organisation manages.
You can still cancel a scheduled upgrade, or upgrade the cluster manually.
An upgrade can run past the end of the window
The window only decides when AME starts an auto upgrade. AME does not pause or stop an upgrade when the window ends, so an upgrade that starts near the end of the window continues after it closes. Choose a window that leaves room for an upgrade to complete, especially on clusters with many nodes.
Upgrade schedule
Each cluster with auto upgrade enabled has an upgrade schedule. New clusters get your organisation's default schedule for upgrades. You enable auto upgrade and select the schedule on the cluster's Patching page, in the Automatic Cluster Upgrades card.
The same page holds the reboot schedule for automatic node reboots. Upgrades and reboots both drain nodes, so choose an upgrade schedule that does not overlap the reboot schedule.
See managing maintenance schedules to create a schedule and assign it to a cluster.
