Docker + Flask + Git, is it worth it?

Question

git

Decided to write a small project, but never worked with either Git or Docker. I would like in the future to be as easy as possible to connect several people (programmers) to the project, so that there are no problems with versions, so that you can roll back if anything, so that you can test everything on the dev server before uploading to the battle, so that the upload itself is as simple as possible .
Hence the question: how justified will a bunch of docker with git be? And in general, is there a need for containers if the project is in Flask?

Answer 1

Swayed too much. It took me weeks to get comfortable with git, and the same amount to get to grips with docker (and then, far from complete: basic level). You would also say that you don't know Flask either, and you are only going to learn python :)
Forget about Docker for now. Learning git for collaborative development is your main goal.

Answer 2

There is a saying "When you don't know if you need a container, you don't need it."
