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 :(
Essentially you need a load balancer hosted somewhere that the traffic hits before getting routed to one of the 2 servers. That could be a VPS running Traefik if you prefer that.
Alternatively you could both run something like IPFS and run the static site on that, but anyone accessing the site would either need IPFS installed, or use a gateway hosted somewhere (Cloudflare has a public for example).
You are not logged in. However you can subscribe from another Fediverse account, for example Lemmy or Mastodon. To do this, paste the following into the search field of your instance: !selfhosted@lemmy.world

Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it’s not obvious why your post topic revolves around selfhosting, please include details to make it clear.

Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
