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.

Rancher is a relatively new player, at the time of writing this book, it has only just hit its 1.0 release. Rancher Labs (the developers) describe Rancher (the platform) as:

"An open source software platform that implements a purpose-built infrastructure for running containers in production. Docker containers, as an increasingly popular application workload, create new requirements in infrastructure services such as networking, storage, load balancer, security, service discovery, and resource management.

Rancher takes in raw computing resources from any public or private cloud in the form of Linux hosts. Each Linux host can be a virtual machine or a physical machine. Rancher does not expect more from each host than CPU, memory, local disk storage, and network connectivity. From Rancher's perspective, a VM instance from a cloud provider and a bare metal server hosted at a colo facility are indistinguishable." -

Rancher Labs also provide RancherOS—a tiny...
