rancher/rke2 v1.23.16+rke2r1

on GitHub

This release updates Kubernetes to v1.23.16 to backport registry changes and fix two critical issues.

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 v1.23.15+rke2r1:

• Generate report and upload test results (#3771) (#3796)
• Bump harvester cloud provider and harvester csi driver (#3783)
• Bump K3s version for tls-cipher-suites fix (#3797)
• Bump vSphere CPI chart to v1.23.3 (#3807)
• Update to v1.23.16 (#3809)
• Bump containerd to v1.5.16-k3s2 (#3831)
  • The embedded containerd version has been bumped to v1.5.16-k3s2. 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.

curl -sfL https://get.rke2.io | sudo INSTALL_RKE2_VERSION=v1.23.16+rke2r1
rke2 server \
  --cluster-reset \
  --cluster-reset-restore-path=<PATH-TO-SNAPSHOT> --token <token used in the original cluster>
