More than "Hello World" in Docker: Build Rails Sidekiq web apps in Docker

There is no shortage of web tutorials on how to display "Hello World" in Docker. The problem is that the path from getting your app to say "Hello World" in Docker, to running production-grade applications in AWS, is often not as straightforward. Even if your app isn't Rails / Ruby, reading through this series will help you know the challenges that lie ahead of you after you decide to use Docker in production.I've used Docker in production for 7 months and have studied it for 4 months before that. In simple setups, doing Docker is very straightforward. Using it in production, however, increases the complexity as there would be a lot of other things to think about. This post will help you manage that complexity.
