Release v1.27.6+rke2r1​

This release updates Kubernetes to v1.27.5.

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 v1.27.5+rke2r1:​

  • Update cilium to 1.14.1 (#4756)
  • Update Kubernetes to v1.27.6 (#4761)

Release v1.27.5+rke2r1​

See https://github.com/rancher/rke2/security/advisories/GHSA-p45j-vfv5-wprq for more information, including mandatory steps necessary to harden clusters against this vulnerability.

Important Notes

  1. 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.
