k3s-io/k3s v1.22.5+k3s1

on GitHub

This release updates Kubernetes to v1.22.5, and fixes a number of issues.

For more details on what's new, see the Kubernetes release notes.

Known Issues:

• #4881: When using embedded etcd and the initial server is started with --agent-token, and this agent-only token does not match the server --token value, additional servers cannot join the cluster. This will be fixed in a subsequent release.
• #4023: When removing servers with etcd from the cluster, ensure that the k3s service is stopped before using kubectl delete to remove the node from the Kubernetes and etcd cluster. You should do this one node at a time to ensure that your cluster does not lose quorum. Failure to follow this process may result in K3s on the deleted node crashing, restarting, and rejoining the cluster.
• #4784: When creating a new cluster, etcd-only servers must be created before control-plane servers.
