Docker Orchestration

By: Randall Smith

Overview of this book

Docker orchestration is what you need when transitioning from deploying containers individually on a single host to deploying complex multi-container apps on many machines. This book covers the new orchestration features of Docker 1.12 and helps you efficiently build, test, and deploy your application using Docker. You will be shown how to build multi-container applications using Docker Compose. You will also be introduced to the building blocks for multi-host Docker clusters such as registry, overlay networks, and shared storage using practical examples. This book gives an overview of core tools such as Docker Machine, Swarm, and Compose which will enhance your orchestration skills. You’ll learn how to set up a swarm using the decentralized building block. Next, you’ll be shown how to make the most out of the in-built orchestration feature of Docker engine and you’ll use third-party tools such as Kubernetes, Mesosphere, and CoreOS to orchestrate your existing process. Finally, you will learn to deploy cluster hosts on cloud services and automate your infrastructure.

Automating host deployment

There are many ways to automate the deployment of Docker hosts. The specifics, as always, depend on the orchestration system. For example, adding new hosts to a Docker Swarm cluster running on Amazon EC2 is as easy as running something like the following:

$ docker-machine create --driver amazonec2
$ docker swarm join --token ABC... manager

For Azure or GCE, it would be the same. Simply replace the driver and pass the appropriate driver specific flags to docker-machine.

This section will look at a couple of different tools that can be used to manage the hosts for a Docker cluster. The first is Terraform which works with just about everything. Next is Docker's own cloud management tool, Docker Cloud. Finally, it will introduce two tools which are in public beta, Docker for AWS and Docker for Azure.


If you plan on running on AWS, GCE, or Azure, consider using the container hosting services that each of them offers. With each service, the tasks of creating and managing...
