Section 1: Docker and Container Fundamentals

In this first section, we will review important Docker and container concepts, and the benefits that Docker provides to developers. After a quick review of Docker, we will move on to how we can add persistent data to a container and how to work with Docker networking to expose containers to the outside world. These basic concepts are essential to fully understanding Kubernetes and understanding how containers run a cluster.

This part of the book comprises the following chapters:

• Chapter 1, Understanding Docker and Container Essentials
