About this book


Docker in Action’s purpose is to introduce developers, system administrators, and other computer users of a mixed skillset to the Docker project and Linux container concepts. Both Docker and Linux are open source projects with a wealth of online documentation, but getting started with either can be a daunting task.

Docker is one of the fastest-growing open source projects ever, and the ecosystem that has grown around it is evolving at a similar pace. For these reasons, this book focuses on the Docker toolset exclusively. This restriction of scope should both help the material age well and help readers understand how to apply Docker features to their specific use-cases. Readers will be prepared to tackle bigger problems and explore the ecosystem once they develop a solid grasp of the fundamentals covered in this book.


This book is split into three parts.

Part 1 introduces Docker and container features. Reading it will help you understand how to install and uninstall software distributed with Docker. You’ll learn how to run, manage, and link different kinds of software in different container configurations. Part 1 covers the basic skillset that every Docker user will need.

Part 2 is focused on packaging and distributing software with Docker. It covers the underlying mechanics of Docker images, nuances in file sizes, and a survey of different packaging and distribution methods. This part wraps up with a deep dive into the Docker Distribution project.
