How to self-host a highly available git server cluster? (lemmy.dbzer0.com)

Edit: it seems like my explanation turned out to be too confusing. In simple terms, my topology would look something like this:

I would have a reverse proxy hosted in front of multiple instances of git servers (let's take 5 for now). When a client performs an action, like pulling a repo/pushing to a repo, it would go through the reverse proxy and to one of the 5 instances. The changes would then be synced from that instance to the rest, achieving a highly available architecture.

Basically, I want a highly available git server. Is this possible?

I have been reading GitHub's blog on Spokes, their distributed system for Git. It's a great idea except I can't find where I can pull and self-host it from.

Any ideas on how I can run a distributed cluster of Git servers? I'd like to run it in 3+ VMs + a VPS in the cloud so if something dies I still have a git server running somewhere to pull from.

Thanks

I would have a standalone Forgejo server to act as your infrastructure server. Make it separate from your production k8s/k3s environment.
If something knocks out your infrastructure Forgejo instance then your prod instance will continue to work. If something knocks out your prod, then your infrastructure instance is still there to pull on.

One of the reasons I suggest k8s/k3s if something happens k8s/k3s will try to automatically bring the broken node back online.

You mean have two git servers, one "PROD" and one for infrastructure, and mirror repos in both? I suppose I could do that, but if I were to go that route I could simply create 5 remotes for every repo and push to each individually.

For the k8s suggestion - what happens when my k8s cluster goes down, taking my git server along with it?
