Nah. I don't like articles with phrases like "you are doing it wrong" when it comes to Docker, because Docker affords you choice. It is up to you to make the choices, and there are some "best practices" around using Docker, but there is no "right way" to use this technology. Use what is "right" for your environment and avoid platitudes like "you are doing it wrong". Anybody that wants a taste of what I'm talking about should stop by #docker on Freenode and see how people are using it.
