I'm a jr. developer and I'm being required to learn docker. I googled around and read a bunch of articles about docker but couldn't really understand what it was for, what problem does it solve.
Example about GIT. When I was at university when we had our thesis, my groupmates and I use facebook messenger or email to pass parts of the code, we indicate what file is it for and on what line, so I understand how GIT resolves a problem. but what about docker? When I deployed to AWS, I ssh thru the server, git clone your repo, do an npm install, so whats the difference? I still have to do that right but with one command?
docker compose run or something? so thats it? hope someone can explain it to me. thank you and have a good day.
