Official docs - Django - superfluous commands? #333

Open SwampFalc opened 1 year ago

SwampFalc commented 1 year ago

Hello,

Being quite new to Docker, I would like to ask about something that appears to be superfluous to me in the official Django docs.

The last line of the Dockerfile is: COPY . /code/

But in the docker-compose.yml file, we have this statement:

    volumes:
      - .:/code

Is the first part not superfluous if the second part exists? Does it not simply make the image larger, without serving a purpose since the content of the folder gets overwritten by the mount anyway?

Or am I missing something?

did you try to test it by removing the COPY instruction?
