ACK One registered clusters include two core components: ack-stub and ack-cluster-agent. ack-stub runs on the ACK One management plane and accepts connection requests from ack-cluster-agent to establish a management channel. ack-cluster-agent runs in your cluster and establishes the management channel with ack-stub. This topic describes how to upgrade these components and lists their release notes.
Upgrade procedure
Always upgrade ack-cluster-agent first. After confirming it runs as expected, upgrade ack-stub. Upgrading either component causes a brief interruption to the management channel. This does not affect services running in the cluster.
-
Log on to the ACK One console. In the left navigation pane, choose Registered Cluster.
-
Click the name of the target cluster. In the left navigation pane, choose Operations > Add-ons.
-
On the Add-ons page, search for ack-stub and ack-cluster-agent. On each component's card, click Upgrade.
