Overview of this book

Containers enable you to package an application with all the components it needs, such as libraries and other dependencies, and ship it as one package. Docker containers have revolutionized the software supply chain in both small and large enterprises. Starting with an introduction to Docker fundamentals and setting up an environment to work with it, you’ll delve into concepts such as Docker containers, Docker images, and Docker Compose. As you progress, the book will help you explore deployment, orchestration, networking, and security. Finally, you’ll get to grips with Docker functionalities on public clouds such as Amazon Web Services (AWS), Azure, and Google Cloud Platform (GCP), and learn about Docker Enterprise Edition features. Additionally, you’ll also discover the benefits of increased security with the use of containers. By the end of this Docker book, you’ll be able to build, ship, and run a containerized, highly distributed application on Docker Swarm or Kubernetes, running on-premises or in the cloud.

  1. To install Git on Windows, open a PowerShell window and use Chocolatey to install it:
PS> choco install git -y
  1. Finally, on your Debian or Ubuntu machine, open a Bash console and execute the following command:
$ sudo apt update && sudo apt install -y git
  1. Once Git is installed, verify that it is working. On all platforms, use the following:
$ git --version

This should output something along the lines of the following:

git version 2.16.3
  1. Now that Git is working, we can clone the source code accompanying this book from GitHub. Execute the following command:
$ cd ~
$ git clone https...
