It seems daunting, but it’s a lot of fun once you do. I started on docker desktop but moved to docker being run on Ubuntu server, but I don’t think it matter where you host it. Very easy to setup and their documentation is pretty good. You technically could be up and running in 10 minutes. Learning how it works will obviously take longer but I find that getting to actually being able to use what I want to quickly removes a lot of barrier to entry. Good luck!
