Overview of this book

Docker has been a game-changer when it comes to how modern applications are deployed and created. It has now grown into a key driver of innovation beyond system administration, with an impact on the world of web development. But how can you make sure you're keeping up with the innovations it's driving, or be sure you're using it to its full potential? Mastering Docker shows you how; this book not only demonstrates how to use Docker more effectively, but also helps you rethink and reimagine what's possible with it. You will cover concepts such as building, managing, and storing images, along with best practices to make you confident, before delving more into Docker security. You'll find everything related to extending and integrating Docker in new and innovative ways. Docker Compose, Docker Swarm, and Kubernetes will help you take control of your containers in an efficient manner. By the end of the book, you will have a broad, yet detailed, sense of what's possible with Docker, and how seamlessly it fits in with a range of other platforms and tools.

Docker Overview

Welcome to Mastering Docker, Third Edition! This first chapter will cover the Docker basics that you should already have a pretty good handle on. But if you don't already have the required knowledge at this point, this chapter will help you with the basics, so that subsequent chapters don't feel as heavy. By the end of the book, you should be a Docker master, and will be able to implement Docker in your environments, building and supporting applications on top of them.

In this chapter, we're going to review the following high-level topics:

  • Understanding Docker
  • The differences between dedicated hosts, virtual machines, and Docker
  • Docker installers/installation
  • The Docker command
  • The Docker and container ecosystem
