Hello everyone, I currently have a downstream RKE2 cluster. I want to upgrade the cluster, but when I go to the Edit Config menu, the available RKE2 versions only go up to v1.31. I’ve tried upgrading the RKE2 version to v1.33 (which is not listed in Rancher) by manually editing the

kubernetesVersion

field in the YAML, and the upgrade was successful. Is that okay? I'm asking because Rancher itself only lists up to v1.31, and I used the RKE2 release from GitHub.

What Rancher version are you on? From the listed Kubernetes versions seems like v2.10. Kubernetes version 1.33 will be officially supported from rancher v2.12.

So you don’t recommend upgrading to a RKE2 version that is not listed in Rancher, right?

Don't do that. If it's not listed it's not supported. Why would you try to force it?

You'll need to upgrade to 2.11 and eventually 2.12 to get support for new Kubernetes minors. If in doubt, check the support matrix.

I would recommend bookmark this support matrix if not already https://www.suse.com/suse-rancher/support-matrix/all-supported-versions/rancher-v2-11-3/
