Cannot update rancher version in addon config

[Mithrandir2k18]

I've deployed rancher with v2.8.2 using the vcluster addon, but I need a rancher version that supports rke2 v1.28, so at least rancher v2.8.3.

What is the recommended way to update rancher vcluster deployments? The config field in harvester isn't editable.

Try changing it by editing the YAML (edit the rancherVersion line, and also the image line that specifies the k3s version if necessary)

Tried it, the harvester UI claims that it's redeploying successfully, but the rancher version still shows as 2.8.2 instead of 2.9.4 I specified. I kept the image version as rancher/k3s:v1.27.10-k3s2 as it should be compatible with rancher v2.9.4 if I read the compatibility matrix correctly.

Happens also if I manually disable and re-enable the addon.

I did a quick test here, just bumping the rancher version to v2.9.4, and while the Harvester UI says the deployment was successful, it's actually not. One of the pods is in CrashLoopBackOff:

# kubectl -n rancher-vcluster get pods | grep helm-install
helm-install-cert-manager-lfvsb-x-kube-system-x-ranc-a6c0166919   0/1     Completed          0              5d1h
helm-install-rancher-ctjsh-x-kube-system-x-rancher-vcluster       0/1     CrashLoopBackOff   14 (76s ago)   48m
helm-install-rancher-vcluster-6xpkc                               0/1     Completed          0              48m

...and the logs say rancher v2.9.4 isn't available:

# kubectl -n rancher-vcluster logs pod/helm-install-rancher-ctjsh-x-kube-system-x-rancher-vcluster|tail -n 1
Error: chart "rancher" matching v2.9.4 not found in rancher index. (try 'helm repo update'): no chart version found for rancher-v2.9.4

I suspect this is because rancher v2.9.4 is a Prime version release, as opposed to a Community release. The repo specified in the rancher-vcluster yaml is https://releases.rancher.com/server-charts/stable/index.yaml:

experimental-addons/rancher-vcluster/rancher-vcluster.yaml

Line 66 in ebb49b6

repo: https://releases.rancher.com/server-charts/stable/

The latest v2.9.x series Rancher there is v2.9.3. To get v2.9.4, you'd need to be a Prime subscriber and update the YAML to refer to the Prime repo URL, but I can't say what that is offhand.

You probably also want to update k3s to rancher/k3s:v1.27.16+k3s1 as that's the latest in the v1.27.x series, but that's unrelated -- the main issue here is whether you have access to Prime or not.
