Upstream ingress-nginx Retirement & Transition to Traefik
Because ingress-nginx was retired upstream as of March 2026, Traefik is now the default for new clusters starting in v1.36 (existing clusters will keep their current ingress upon upgrade to avoid breakage). This transition brings the following structural changes:
- Airgapped Environments: The
rke2-images-coretarball now contains Traefik images instead ofingress-nginx. The standalonerke2-images-traefiktarball has been removed. Users who must continue usingingress-nginxwill now need to manually provide therke2-images-ingress-nginxtarball. - Future Removal: The
ingress-nginxchart will not receive any additional updates and will be completely removed in v1.37 for community users. - Prime Customers: Please refer to the official product documentation for specific Prime considerations.
This release updates Kubernetes to v1.36.0.
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:
