Extending Docker

Overview of this book

With Docker, it is possible to get a lot of apps running on the same old servers, making it very easy to package and ship programs. The ability to extend Docker using plugins and load third-party plugins is incredible, and organizations can massively benefit from it. In this book, you will read about what first and third party tools are available to extend the functionality of your existing Docker installation and how to approach your next Docker infrastructure deployment. We will show you how to work with Docker plugins, install it, and cover its lifecycle. We also cover network and volume plugins, and you will find out how to build your own plugin. You’ll discover how to integrate it with Puppet, Ansible, Jenkins, Flocker, Rancher, Packer, and more with third-party plugins. Then, you’ll see how to use Schedulers such as Kubernetes and Amazon ECS. Finally, we’ll delve into security, troubleshooting, and best practices when extending Docker. By the end of this book, you will learn how to extend Docker and customize it based on your business requirements with the help of various tools and plugins.

Vagrant (again)

As we have already discovered earlier in this chapter, Vagrant can be used as a virtual machine manager. We have already used it to bring up a local Ubuntu 14.04 instance using VirtualBox on our local machine; however, if we wanted to, we could have done this using VMware Fusion, Amazon Web Services, DigitalOcean, or even OpenStack.

Like Puppet and Ansible, when Docker was first released, there were a lot of articles published around Vagrant versus Docker. In fact, when the question was asked on Stack Overflow, the authors of both Vagrant and Docker weighed in on the question. You can read the full discussion at

So, in what ways can Vagrant support Docker? There are two main ones we are going to be looking at. The first is the provisioner.

Provisioning using Vagrant

When we worked out way through Puppet, we used Vagrant to launch Ubuntu 14.04 locally using VirtualBox...
