Hello everyone!
My friend and I have each bought an optiplex server. Our goal is to selfhost a web app (static html) with redundancy. If my server goes down, his takes over and vice versa. I’ve looked into Docker Swarm, but each server has to be totally independent (each runs its own apps, with a few shared ones).
I can’t find a solution that allows each server to take over and manage loadbalancing between the two. Ideally with traefik, because that’s what we’re currently using. To me the real issue is the DNS A record that point to only one IP :(
Your challenge is that you need a loadbalancer. By hosting the loadbalancer yourself (e.g. on a VPS), you could also host your websites directly there…
My approach would be DNS-based. You can have multiple DNS A records, and the client picks one of them. With a little script you could remove one of the A Records of that server goes down. This way, you wouldn’t need a central hardware.
The VPS remains this single point of failure :(
The DNS-based approach seems to be the best bet for my use case.
