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.

The three tools that we have looked are not the only schedulers available, there are also tools such as the following to name a few:

All these schedulers have their own requirements, complexities, and use cases.

If you had asked me a year ago which of the three schedulers that we have looked in this chapter would I recommend, I would have said Amazons EC2 Container Service. Kubernetes would have been second and I probably wouldn't have mentioned Rancher.

In the past 12 months, Kubernetes has vastly reduced its complexity when it comes to installing the service has removed its biggest barrier to people adopting it, and as we have demonstrated, Rancher reduces this complexity even further.

Unfortunately, this has left EC2 Container Service feeling like it is a lot more complex to both configure and operate when compared to the other tools, especially...
