The book starts by introducing containers and explains how they are different from virtual machines, and why they are the preferred tool for developing applications. You will understand the working of images, containers, and their associated storage and will see how all the moving parts bind together to work synchronously.
the book will then focus on Docker swarm, the mechanism for Orchestrating several running Docker containers. It then delves deeper into Docker networking. Towards the end, you will learn how to secure your applications, especially by leveraging the native features of Docker enterprise edition.
