Ask HN: What’s the finest supply to study Docker in 2023?

I do know docker for a very long time however I by no means used it in critical tasks. I discover it arduous to search out good and particularly updated tutorials. I’m particularly excited by a tutorial on the way to run (function department) containers which spin up on bitbucket pipelines/GitHub actions for guide and automatic testing for PHP and Node functions (containers ought to exist so long as a function department exists). I discovered some random YouTubers which give a pleasant intro/demo into some options however not likely a deep dive.
