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.

In the previous chapters, we experienced using combinations of the tools together.

For example, we have been using both Docker Storage and Network plugins to create a highly available WordPress installation using both the tools provided by Docker themselves, that is, Docker Compose and Docker Swarm, as well Kubernetes and Rancher.

We also deployed our underlying Docker infrastructure using Docker Machine, Ansible, as well as tools such as Kubernetes and Rancher.

Then, we deployed various first-party and third-party plugins to help with storage, networking, and features such as load balancing to take full advantage of the environment that we have been deploying to, such as Amazon Web Service and DigitalOcean.

All the tools that we have looked at compliment the core Docker Engine, and in most cases, there is little or no change needed to be made to your Docker images to start using the plugins or third-party tools.

All of this means that it is relatively easy to build a highly available...
