Use single Dockerfile for development and production

I have been wondering for a really long time how to keep up to date the Dockerfiles in my project. I’ve always had two of them, one for the dev environment, and the second one for building my production container with dependencies, code build, etc. If I needed to change something I had to update both files.

I knew that dockerfiles allow us to define multiple stages, and I had used them, but still had a problem. In my production dockerfile I had stages, like building my frontend application and installing backend dependencies and final stage. I don’t need my code inside the container for development, because I attach my code using volume, so there is no reason to increase the building time of the development environment. So for the dev environment, I was using another one dockerfile.
