Recently Docker brought some new stuff that I found very useful for developers. They are still in the experimental phase but are already very useful. Try them and give your feedback to the Docker team. The code I’m using for this is available here. Let’s start… Init Writing a Dockerfile when starting with a new application is tedious. Why?
