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.

Getting started with DC/OS

Installing DC/OS is a complicated process to be covered here, and the instructions differ for each environment. Be sure to read through the documentation before you start this process. There are features, such as the number of masters or external persistent storage that must be enabled at install time and cannot be changed later without reinstalling. Installation instructions are available at


The easiest way to get Mesosphere up and running is to use the stack install on AWS or use ACS which runs Mesosphere.

There are a few things to be aware of if you are installing manually or on local hardware:

  • Nodes must have at least two cores or virtual processors.

  • DC/OS nodes must be running CoreOS 7, RHEL 7, or CoreOS.

  • All nodes in the cluster must have NTP enabled. NTP servers are set in /etc/systemd/timesyncd.conf. After the NTP servers have been set, run systemctl, enable systemd-timedated.service and systemctl, and...
