Mastering Docker - Third Edition

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.

We will focus on the web aspect of Docker Hub and the management you can do there.

The home page, which can be found at, contains a Sign-Up form and, in the top-right, an option to Sign in. The odds are that if you have been dabbling with Docker, then you already have a Docker ID. If you don't, use the Sign-Up form on the home page to create one. If you already have a Docker ID, then simply click Sign in.

Docker Hub is free to use, and...
