Hey, So we are migrating to k8s 1.24 and we use rancher to centralise our cluster (rancher version 2.5.15 using the docker image rancher/rancher) but when connection the cluster I got issue with api , so I had to look into the issue and found out that it might be that rancher versions under 2.6 are not supporting the new k8s version . does anyone faced same issue ? and is it right that v2.5.15 of rancher does not support k8s 1,24 ?

Here is the support matrix for the version you are using: https://www.suse.com/assets/v2.5.15-Support-Matrix.pdf

just a note: we are using a vm to spin up the rancher docker container

That’s likely because the way service account tokens are handled changed in 1.24 and the Rancher version you’re using doesn’t support 1.24.

thanks for the explanation
