Well it was mostly pieced together information - the one that I already had from experience and the rest pulled from the Internet.

But which parts do you mean exactly? How to setup nginx to act as a reverse proxy? Or putting together a docker-compose? I'm thinking of doing some kind of guide for this type of thing on my blog - basically from setting up a Hetzner VPS box to running a docker-compose'd app and exposing it on a HTTPS endpoint for your own domain (so setting up DNS probably also).
