rancher/rke2 v1.26.15+rke2r1

on GitHub

This release updates Kubernetes to v1.26.15.

Important Notes

Canal uses flannel 0.24.3 which includes a bug: every 5 seconds it tries to add ipv6 iptables rules and fails if the node does not have an ipv6 address. The consequence is the log "Failed to ensure iptables rules: error setting up rules: failed to apply partial iptables-restore unable to run iptables-restore (, ): exit status 4" appears every 5 seconds in the flannel container of the canal pod.

Flannel daemonset is not tolerating node taints: "node-role.kubernetes.io/etcd:NoExecute", "node-role.kubernetes.io/control-plane:NoSchedule" and "node.cloudprovider.kubernetes.io/uninitialized:NoSchedule" which can create problems when deploying with Rancher in certain cloud-providers (e.g. vShpere or DigitalOcean).

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
