How to set up a decentralized game/chat server (sh.itjust.works)

I've been kicking around the idea of running a server for games and chat woth some of my friends, but worry about everyone getting cut off when there's a disruption.

I've started looking into kubernetes out of curiosity, and it seems like we could potentially set up a cluster with master nodes at 3+ locations to hose whatever game server or chat server that we want with 100% uptime, solving my concerns.

Am I misunderstanding the kubernetes documentation, and this is just a terrible idea? Or am I on the right track?

I'd rent one (small) VPS for $10 a month and split the bill.

We don't want to pay for a VPS. We've been burned by that too often in the past were you go months paying for a minecraft server that noone is using after the first month

Fair enough. I mean I'd pay about 200€ a year in electricity to run 3 efficient computers. And my VPS is only 73€ and I never have to pay for replacement parts (SSDs, harddisks) which I had to replace at home. And then they have gigabit network, low latency, a proper IP address, it didn't fail yet so their reliability >99.6% seems to be correct. And that's all way better than what I have at home. So it's a no-brainer to go for that. But your calculation might be different.

I mean ultimately there is no harm in trying. If you have 3 old computers laying around, you might as well try setting up a kubernetes cluster. I think it's going to prove difficult to handle the IP addresses but I'm not an expert on high availability and gaming clients.
