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.

Docker Machine

So, when you ran the Docker Quickstart Terminal application, it created a bunch of certificates, SSH keys, and configured your user's environment to run Docker. It also launched a virtual machine running Docker.

Developing locally

The Docker Quickstart Terminal application did this using Docker machine, you can check the status of the machine launched by the application by running the following command:

docker-machine active

This will list the names of any active machines, the default machine launched when you first install Docker is called default, if you run:

docker-machine status default

It should tell you that the virtual machine is currently running. Finally, you should be able to SSH into the virtual machine by running the following command:

docker-machine ssh default

You will notice that when you SSH into the virtual machine, it is running the Boot2Docker distribution.


Boot2Docker is an extremely lightweight Linux distribution based on Tiny Core Linux, and its one...
