I would give docker compose a try instead. I found Proxmox to be too much, when a simple yaml file (that can be checked into a repo) can do the job.

Pay attention to when people say things can be improved (secrets/passwords, rootless/podman, backups), etc. And come back to them later.

Just don’t expose things to the internet until you understand the risks and don’t check in secrets to a public git repo and go from there. It is a lot more manageable and feels like a hobby vs feeling like I’m still at work trying to get high availability, concurrency and all this other stuff that does not matter for a home setup.
