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.

In this chapter, you saw the building blocks that are needed for a Docker cluster. No matter what orchestration tool is used, there will be the need for a registry to store your images, an overlay network for inter-container communication, and network storage so that your containers can get at their data wherever in the cluster they start. There are many options to fill each role. While the choice of solution is important, it's easy to switch between systems if needed. Some will be better in certain environments and workloads. The next chapter will dive into orchestrating a Docker cluster using Docker Swarm.
