RKE2 - v1.25.5+rke2r2

This release updates containerd to v1.6.14 to resolve an issue where pods would lose their CNI information when containerd was restarted.

Important Note

If your server (control-plane) nodes were not started with the --token CLI flag or config file key, a randomized token was generated during initial cluster startup. This key is used both for joining new nodes to the cluster, and for encrypting cluster bootstrap data within the datastore. Ensure that you retain a copy of this token, as is required when restoring from backup.

You may retrieve the token value from any server already joined to the cluster:

cat /var/lib/rancher/rke2/server/token

Changes since v1.25.5+rke2r1:

• Bump containerd to v1.6.14-k3s1 (#3746)
• The embedded containerd version has been bumped to v1.6.14-k3s1. This includes a backported fix for containerd/7843 which caused pods to lose their CNI info when containerd was restarted, which in turn caused the kubelet to recreate the pod.
• Windows agents now use the k3s fork of containerd, which includes support for registry rewrites.
