Sorry I’m so green, gotta start somewhere!

Start with the documentation. Docker has a great introductory section that teaches you the basics.

https://docs.docker.com/get-started/introduction/ (the pushing your image part is not that important, the rest is)

Running a project that does things you don’t know is not the best thing to learn. Learning is done by going through the basics first, not immediately firing docker compose, which is one step above pure docker.
