RKE2 - v1.28.3+rke2r2

This release fixes an issue with identifying additional container runtimes.

Important Notes

This release includes a version of ingress-nginx affected by CVE-2023-5043 and CVE-2023-5044. Ingress administrators should set the --enable-annotation-validation flag to enforce restrictions on the contents of ingress-nginx annotation fields.

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
