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 an impact on the world of web development. But how can you make sure you're keeping up with the innovations it's driving, or be sure you're using it to its full potential? Mastering Docker shows you how; this book not only demonstrates how to use Docker more effectively, but also helps you rethink and reimagine what's possible with it. You will cover concepts such as building, managing, and storing images, along with best practices to make you confident, before delving more into Docker security. You'll find everything related to extending and integrating Docker in new and innovative ways. Docker Compose, Docker Swarm, and Kubernetes will help you take control of your containers in an efficient manner. By the end of the book, you will 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.

Deploying local Docker hosts with Docker Machine

Before we journey out into the cloud, we are going to look at the basics of Docker Machine locally by launching it, using Oracle VirtualBox to provide the virtual machine.

VirtualBox is a free virtualization product from Oracle. It allows you to install virtual machines across many different platforms and CPU types. Download and install VirtualBox from

To launch the machine, all you need to do is run the following command:

$ docker-machine create --driver virtualbox docker-local

This will start the deployment, during which you will get a list of tasks that Docker Machine is running. To launch your Docker host, each host launched with Docker Machine goes through the same steps.

First of all, Docker Machine runs a few basic checks, such as confirming that VirtualBox is installed, and creating...
