Docker Deep Dive
Docker Deep Dive
Zero to Docker in a single book!
About the Book
Starting from scratch, you'll learn what containers are, how to start them, stop them, and delete them. You'll learn how to run applications in them and manage it all at scale. You'll also learn the theory of how it all works and plugs together behind the scenes so that you don't just know the right commands, but you also know what's going on behind the scenes.
The book is up to date with all of the latest core technologies from Docker, Inc.
