Using docker force you to declare step by step what you need to build/use your code. If you combine that with good CI/CD, that easier to provides help to the junior developer if you can quickly reproduce the environment. I had a bad experience with a project that I was assigned to "help". The build steps documented used incompatible lib version. It's hard to help if you can't even build/run their codes.
