I started this deployment without checking the K3s version that Rancher needs. So before I scratched everything and restarted I tried something and documented it. It did not work for me but it could be usueful
All the nodes are running version 1.25.5 of Kubernetes and Rancher’s helm chart is working only up to version of 1.25.0. Oh hell… Here goes nothing. Pull the whole installation and edit the Chart yaml to allow a later version
helm pull rancher-stable/rancher --untar
nano rancher/Chart.yaml
Save and Exit
Then run the command to install it from the local folder
helm install rancher ./ \
> --namespace cattle-system \
> --set hostname=The_FQDN_You_Chose \
> --set bootstrapPassword=admin
Wait a few minutes and
Well it is not done yet. You can monitor the installation with these commands
kubectl -n cattle-system rollout status deploy/rancher
kubectl -n cattle-system get deploy rancherNow it is ready
On your browser type in the fqdn and login with the admin password
I thought it worked but… the dashboard did not load so scratch and restart….
