Notes
- Traefik and its CRDs are managed by K3s through auto-deploy manifests, not through manual Helm commands. Upgrading Traefik should be done by updating K3s, not by running
helm upgradedirectly. - Rancher manages several sub-charts (fleet, webhook, turtles, system-upgrade-controller). These are installed and upgraded by Rancher automatically. Do not modify them independently.
