In preparation for expanding my K3s cluster, I was planning to move my Rancher from a current single node k3s to my actual cluster, or install a new Rancher instance on the cluster.
However, when deleting the cluster from the old rancher, almost all of my resources were also deleted from the cluster, which I did not expect to happen.
So now I spent some time to restore the most important service.
Currently my matrix server and my wiki is not reachable because of this.
