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?

Just be careful how much you depend on the git repo for Flux.

I made the mistake of doing the same thing but took it a two further and used Gitea for my container images and helm charts. When I messed up Gitea during an ArgoCD sync, I couldn't roll back because the custom helm chart for Gitea and Postgres came from Gitea.

It also messed up every other application and ended up deleting all my resources during auto sync.

Best thing I ended up doing was mirroring Gitea to GitHub, including images and charts. Then using that for ArgoCD.
