Rancher 2.8 doesn’t support Kubernetes v1.23. That minor is long EOL. You should be on 1.25, 1.26, or 1.27 for Rancher 2.8. https://github.com/rancher/rancher/releases/tag/v2.8.2 https://www.suse.com/suse-rancher/support-matrix/all-supported-versions/rancher-v2-8-2/

Yes, this is a legacy cluster, I was hoping to get some visibility into the performance. It will just take time to upgrade 52 nodes. We'll move up to 1.27.
