So, I’m trying to roll a K3s cluster, basically to learn new stuff (yup, I definitely don’t need it, but I’d like to).

I imagined it to be composed by a master plane (virtualized in a server in my house) and a node worker (on a Hetzner VPS). The worker node should, for the moment, only serve a reverse proxy to route connections to my home server (which is gonna host Synapse, Mastodon and some things, perhaps) and later on maybe SSO and other thingies.

This is my problem: I guess the best way to route the traffic between the w.n. and the m.p. would be a Wireguard tunnel, which, I suppose, I could directly manage via kubectl. You see where this is going. Until I a have a working tunnel I cannot manage the remote working node, but at the same time I need a tunnel to be able to connect to said working node.

So, I guess my idea has some flaws. How could I manage to do it?
