For a detailed introduction on Docker plugins, we can suggest to read the official documentation pages. Here is a starting point https://docs.docker.com/engine/extend/and, also, Docker will probably release a tool to get plugins with a single command, refer to https://docs.docker.com/engine/reference/commandline/plugin_install/.

We recommend you to refer to Extending Docker book, Packt, if you want to explore how to integrate new features into Docker. The book emphasis is on Docker plugins, volume plugins, network plugins, and how to create your own plugins.

For Flocker, ClusterHQ made available an automated deployment mechanism to deploy a Flocker cluster on AWS with CloudForm templates, which you can install using the Volume Hub. For registering and starting such a cluster, go to https://flocker-docs.clusterhq.com/en/latest/docker-integration/cloudformation.html. For a step-by-step explanation of the detailed procedure, refer to Chapter 3 of Extending Docker, Packt.

Here we'll go manually, because we must integrate Flocker and Swarm.
