Book recommendation - Docker for Developers

I started developing Magento 2 projects a year ago. My beloved development environment with virtualization via Vagrant was not an option anymore for such a monster application. Turning back the evolution with installing PHP and a webserver locally was not an option either. I needed something faster and Docker was that something. I made the normal Getting started tutorial and it felt good and fantastic, but I was not able to transform the learned knowledge to my current project. This is not unusual if I lern new software that has a huge field of use. It is possible to search for Put my existing application into Docker in the world wide web, but the result can be disappointing. My decision was firm, the current project has to wait until I have lerned on a more advanced but minimal project how I can integrate my project into Docker. Luckely there was the book Docker for Developers from Chris Tankersley. I can highly recommend this book for every PHP developer that needs a small introduction into Docker.
