I started with the 2020 tutorial from these guys. They’ve updated it a few times through the years so I can’t speak to how good the new version is, but I’m sure it’s probably plenty to get started.

After I followed this guide, I’ve deviated significantly as I learned and started to do my own thing. It’s a great place to start and learn the basics of containerized applications and once you have that then you can host most things that are dockerized. All I need to do now to start up a new service is pull up the README on Docker Hub (or better yet, if LinuxServer.io has a container that does what I want to do, on their website), figure out what I want to do with the variables and any setup that needs to happen, and then I add it to my .yml and start it up!

I’ve got it all tracked now on GitHub so I can see what I’ve changed and when and if something were to go wrong I could revert back to a known-good configuration.
