The Docker Handbook

Originally published on freeCodeCamp and later rewritten as open-source on GitBook, The Docker Handbook can be an excellent starting point for your DevOps journey. 

The book is divided into several sections each dealing with topics like Container Manipulation, Image Creation, Network Management, and Multi-container Services.

The book receives regular updates from me as well as various contributors around the world.
