Since the book is called "Complete Docker" it's broad in scope; I pitched the book to my editor as spanning beginner, intermediate, and production topics. I won't really go into
advanced Docker in the book.
Right now the first several chapters serve as a "I'm a programmer but know nothing about Docker" guide, the mid of the book dives into Docker-specifics (how exactly volumes work, how Docker networking works, etc), and then it graduates into the Docker Ecosystem, dedicating some time to covering tools like Kubernetes, CoreOS, Fleet, Amazon ECS.
The latter portion of the book is a number of recipes: how to get a Ghost blog running behind an nginx proxy; how to launch WordPress with MariaDB; how to launch an ELK stack, etc.
