The simplicity of the Dockerfile format is probably one of the reasons why Docker managed to become so popular in the first place. Getting something working is fairly easy. Producing a clean, small, secure image that will not leak secrets might not be as straightforward though.
This post will try to share some best practices when writing a Dockerfile for a Ruby application. Most of these suggestions should be valid for any other runtime as well.

On Pair Programming
Many people who work in software development today have heard of the practice of pair programming, yet it still only has patchy adoption in the industry. One reason for its varying acceptance is that its benefits are not immediately obvious, it pays off more in the medium- and long-term. And it's also not as simple as "two people working at a single computer", so many dismiss it quickly when it feels uncomfortable. However, in our experience, pair programming is vital for collaborative teamwork and high quality software.
