github rancher/rke2 v1.21.4+rke2r1

2 years ago

This release updates Kubernetes to v1.21.4, and fixes a number of issues.

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

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
