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.

This chapter explored different ways to automate the infrastructure that is used to run a Docker cluster. It looked at using configuration management while a node is running, configuring a node at boot with Cloud-Init, and building custom images with Packer. We also covered using Terraform and Docker Cloud to manage a cluster. Finally, some tips were shared for deprovisioning nodes when they are no longer needed.

Where you go next is up to you. This book has provided an introduction to Docker Orchestration using several tools. Successfully running a Docker cluster requires a number of different services including registries, overlay networks, shared storage, the orchestration tool itself, log and resource monitoring, and continuous integration. The specific tools and work flows will vary from cluster to cluster. This book was only able to scratch the surface of what is possible. Hopefully, you will be able to take what you have learned here and use it to build a scalable, reliable...
