How bad of an idea is it to host the git repo for Flux on the same cluster that flux is managing? (alien.top)

I have a homelab k8s cluster running great using flux, several apps, based on the common homelab templates folks use. I currently host the gitops repo on a gitea instance running in a separate TrueNAS instance. This works fine but I'm not totally satisfied with how gitea is running. My inclination is to just run gitea in the k8s cluster, yes the same one that the gitops repo is managing. I realize this is bad in a bunch of obvious ways. But I'm wondering if it's possibly not as bad as I might think it is. Of course I'd have a backup of the repo on my laptop. So if the gitea became unavailable for gitops I'd probably be able to bootstrap it from the backup repo. Any folks have experience running it like this?

Doesn't seem like a problem unless the gitops controller is managing repositories too.

This isn't a cyclic dependency, and doesn't affect failure modes. If the git server fails, the gitops controller fails or waits.

It's a bit more of a problem if the cluster IaC itself is managed using this git instance, but that's easy enough to solve with backups or not doing that.

Since this is a home lab, none of this is problematic. Feel free to condense everything - even the backup controller. Just make sure you have a way to access data and manually intervene if it shits the bed.
