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.

Deploying local Docker hosts with Docker Machine

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

Important note

VirtualBox is a free virtualization product from Oracle. It allows you to install VMs across many different platforms and central processing unit (CPU) types. Download and install VirtualBox from https://www.virtualbox.org/wiki/Downloads/.

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 certificates and a directory structure in which it will store...
