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. 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.

Multipass is a tool provided by Canonical, the makers of Ubuntu, to quickly launch and manage multiple Ubuntu VMs locally. It works slightly differently from Vagrant in that rather than defaulting to using VirtualBox, it will use your operating system's default hypervisor.

To install Multipass on macOS, you can run the following command, which again uses Homebrew and Cask:

$ brew cask install multipass

To install on an existing Ubuntu desktop, you can use the Snap package manager by running the following command:

$ snap install multipass --classic
