    About this ebook

    You're a developer who knows nothing to Docker. Which is fine, except that you need to create and run your first containerized application using Docker.

    Don't worry: I have you covered. I've been training hundreds of developers like you during 17 years, and converted my experience into this book. I know from experience teaching what takes more time to learn in Docker, and will spend time only where appropriate.

    Plus this book is packed with exercises and samples where you run your own containers and create your own Docker images.

    Read this book, and you can create and run your first containerized application using Docker within a week.

    Arnaud Weil

    Arnaud Weil is a born developper: when he was a kid he was controlling his electric train using an Atari ST and some self-made electronics, then as a teenager created and distributed worldwide one of the first Web browsers for some of the first pocket computers, when the Web was just beginning. In fact, he loves coding. Then came .NET and from 2001 Arnaud has been coding using ASP.NET, WPF, WinForms, Silverlight, WCF, XAML for all kind of applications from factory tools to smarphone applications to house control solutions. When not coding, he teaches fellow developers and provides consulting for development teams to reach their targets in the most efficient way. His status as a freelancer allows him to help his clients with many different projects. As things move on, Arnaud also learned to love HTML5, JavaScript and all the great tools that allow building professional software with those technologies. He puts an emphasis on writing modular, clever programs using agile methods and a bunch of automated testing. But what Arnaud enjoys most is helping other developers: that's why he teaches, speaks, and began writing books.

    Introduction

    What this book is not

    I made my best to keep this book small, so that you can learn Docker quickly without getting lost in petty details. If you are looking for a reference book where you’ll find answers to all the questions you may have within the next 4 years of your Docker practice, you’ll find other heavy books for that.

    My purpose is to swiftly provide you with the tools you need to create and run your first containerized application using Docker, then be able to look for more by yourself when needed. While some authors seem to pride themselves in having the thickest book, in this series I’m glad I achieved the thinnest possible book for my purpose. Though I tried my best to keep all of what seems necessary, based on my 16 years experience of teaching.

    Prerequisites

    In order for this book to meet its goals, you must have basic experience creating applications with one of the following technologies: .NET Core, Java, Node.JS, PHP or Python.

    How to read this book

    This book’s aim is to make you productive as quickly as possible. For this we’ll use some theory, several demonstrations, plus exercises. Exercises appear like the following:

    Do it yourself: Time to grab your keyboard and code away to meet the given objectives.

    In code samples, a backslash is used in order to wrap long lines. Do not type theses backslashes when you copy code from the book.

    Tools you need

    The only tools you’ll need to work through this book are the following:

    A Windows, Linux or Mac machine that meets the specifications for Docker Engine or Docker Desktop.

    A GIT client.

    A text editor.

    Source code

    All of the source code for the demos and do-it-yourself solutions is available at https://bitbucket.org/epobb/dockerbookfiles

    It can be downloaded as a ZIP file, or if you installed GIT you can simply type:

    git clone https://bitbucket.org/epobb/dockerbookfiles.g\

    1. Why Docker?

    If you’re in a hurry, you can safely skip this chapter and head straight to the Get Docker up and running chapter. This Why Docker? chapter is there for those that want to know why containers should be used.

    1.1 A DevOps enabler tool

    Docker is an engine that runs containers, and containers as a tool allow to solve many challenges created by the growing DevOps trend.

    In DevOps, the Dev and Ops teams have conflicting goals:

    As an agile developer I want to frequently publish my applications so that deployment becomes a routine. The rationale behind this is that this agility makes the go to production event a normal, frequent, completely mastered event instead of a dreaded disaster
