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.

Using a private registry

Mesosphere has the ability to use a private Docker Registry for images. Images can be pulled from a local registry in the same way one would with Docker; using the registry address followed by the image. For example, to use the myapp image that is on, you would set the image to

It is also possible to host a private registry on your Mesosphere cluster. The registry can be set up using host networking or with either VIP or Marathon-LB as the load balancer. The following example creates an insecure registry which uses Marathon-LB:

  "id" : "registry", 
  "cpus" : 0.5, 
  "mem" : 128, 
  "instances" : 1, 
  "labels" : { 
    "HAPROXY_GROUP" : "external" 
  "container" : { 
    "type" : "DOCKER", 
    "docker" : { 
      "network" : "BRIDGE", 
      "image" : "registry:2", 
      "portMappings" : [ 
          "containerPort" : 5000...
