High Available k3s Kubernetes cluster with keepalived, galera and longhorn

I’m no k3s expert, but this surprised me:

> I noticed that there is only one k3s node that has the control-plane,master role. If that node fails you can no longer manager the cluster.

This feels like a failing of k3s that should be addressed within k3s, rather than adding duct tape elsewhere. Kubernetes has built-in mechanisms (Leases) for handling these kinds of problems.
