Mastering Docker, Fourth Edition - Fourth 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 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.

An introduction to Docker Machine

Before we roll our sleeves up and get stuck in with Docker Machine, we should take a moment to discuss what place it now occupies in the overall Docker ecosystem and what it actually is.

Docker Machine's biggest strength was that it provided a consistent interface to several public cloud providers, such as Amazon Web Services (AWS), DigitalOcean, Microsoft Azure, and Google Cloud, as well as self-hosted VM/cloud platforms (including OpenStack and VMware vSphere) to quickly launch and configure individual Docker hosts. Being able to target all of these technologies using a single command with minimal user interaction is a very big-time saver. If you need to quickly access a Docker host in AWS one day and then in DigitalOcean the next, you know you are going to get a consistent experience.

Also, it allows you to launch a local Docker host, which was useful for operating systems such as the non-Professional versions of Windows 10, where Docker...
