reverse proxy over vpn without docker? (lemmy.world)

I'm looking into replacing cloudflare with a VPS running a reverse proxy over a VPN, however, every solution I see so far assumes you're running Docker, either for the external reverse proxy host or the services you're self hosting.

The VPS is already virtualized (perhaps actually containerized given how cheap I am) so I don't want to put Docker on top of that. The stuff I'm self hosting is running in Proxmox containers on a 15 year old laptop, so again, don't want to make a virtual turducken.

Besides, Docker just seems like a pain to manage. I don't think it was designed for use as a way to distribute turnkey appliances to end users. It was made for creating reproducible ephemeral development environments. Why else would you have to specify that you want a storage volume to persist across reboots? But I digress.

Anyway, I want to reverse proxy arbitrary IP traffic, not just HTTP/S Is that possible? If so, how?

My initial naive assumption is that you set up a VPN tunnel between the VPS and the various proxmox containers, with the local containers initiating the connection so port forwarding isn't necessary. You then set up the reverse proxy on the VPS to funnel traffic through the tunnel to the correct self-hosted container based on domain name and/or port.

I've recently switched to pangolin, which works like cloudflared tunnels, and it's been pretty good.
They offer docker support but they also support installing manually. You install pangolin on your vps via a setup script, and you install newt on a machine inside your homelab. It supports raw udp/tcp in addition to http.

I'd challenge what you said about docker, though. There is very little overhead in making a docker turduckin.
And actually docker is exactly for delivering turnkey applications, not for reproducable dev environment; I imagine that they don't have a default data persistence because not everything needs it and that's less secure by default. LXC (which is what you'll mostly use in proxmox) and VMs seem more for reproducable dev environments, afaict. And there are some really good tools for managing the deployment of docker artifacts, compared to doing it yourself or using LXCs: for example dockge or portainer. I gave proxmox a try, but switched to portainer recently, because managing containers was easier and they still let you define persistent shared volumes like proxmox does.

Proxmox is still good if you need to run VMs, but if all you need is OCI/docker containers, then there are simpler alternatives, in my limited experience.
