Mastering Docker - Fourth Edition

By: Russ McKendrick

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 a significant impact on the world of web development. Mastering Docker shows you how you can ensure that you're keeping up with the innovations it's driving and be sure you're using it to its full potential. This fourth edition not only demonstrates how to use Docker more effectively but also helps you rethink and reimagine what you can achieve with it. You'll start by building, managing, and storing images along with exploring best practices for working with Docker confidently. Once you've got to grips with Docker security, the book covers essential concepts for extending and integrating Docker in new and innovative ways. You'll also learn how to take control of your containers efficiently using Docker Compose, Docker Swarm, and Kubernetes. By the end of this Docker book, you’ll 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.

Technical requirements

As in previous chapters, we will continue to use our local Docker installations. Also, the screenshots in this chapter will be from my preferred operating system, macOS. Toward the end of the chapter, we will use Multipass to launch a local Docker Swarm cluster.

As before, the Docker commands we will be running will work on all three of the operating systems we have installed Docker on so far, however, some of the supporting commands, which will be few and far between, may only apply to macOS and Linux-based operating systems.
