cattle-systemSUCc

04/25/2025, 9:19 PMThe SUC deployment managed by Rancher is used to upgrade the rancher-system-agent binary and systemd service that is installed on the nodes. It does not use the charts or manifests from the SUC repo.

04/25/2025, 9:20 PMThey are in the process of getting moved from rancher/rancher to rancher/system-upgrade-controller, but the ones currently used by rancher are here: https://github.com/rancher/charts/tree/dev-v2.11/charts/system-upgrade-controller

04/25/2025, 9:25 PMok, is it recommended to apply custom plans to the cattle-system namespaces then? My goal is to update rke2.

04/25/2025, 9:36 PMI think it is set up to watch plans in all namespaces? I wouldn’t put custom plans in cattle-system, no.

04/25/2025, 9:37 PMBut don’t do that. If you’re using Rancher to provision the cluster you must use Rancher to set the RKE2 version. Don’t use the SUC to upgrade the cluster out from under Rancher, it will get VERY mad at you for that.

04/25/2025, 9:39 PMOK, I'll check if I get rke2 upgraded by using rancher. I had an issue with that feature in 2.10.7. Just testing with 2.11.1...

04/25/2025, 10:09 PMIt was created with an rancher version 2.6.x. I reinstalled rancher and then imported the rke2 cluster.

04/26/2025, 10:29 AMAs you mention this. Another odd behavior is that the cluster irregular disconnects from rancher every 2-3 days. This happens sonce it is imported.
