The Docker documentation is pretty terrible, but it’s a decent start. Start by looking at docker-compose.yml files for the services you want to run and the write-ups for those.

Something nobody ever told me, that I had to figure out myself, is that docker-compose.yml files can be placed anywhere you want.

Well, to be fair, I actually bought it to use as a desktop and upgraded it accordingly. Then a few months later I decided to build a Ryzen system. Optiplex got moved to server duty.

I bought an Optiplex 7050 SFF for $100 USD at the start of 2023. Upgraded it to an i7-7700, 32GB RAM, 300W PSU from an XE3 model (stock is 180W), and threw in a spare Nvidia K1200 Quadro for shits and giggles. Runs almost my entire suite of self-hosted applications without a hitch.

That’s… Not a bad idea…
