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.

Chapter 6. Working with Mesosphere

Apache Mesos is a distributed kernel. It allows one to work on a cluster of servers as if they were a single resource. Mesosphere and DC/OS build on this to provide a robust system for running any workload, including Docker containers. Native support for distributed workloads such as Cassandra and Jenkins, as well as Docker, make for a powerful combination.

Microsoft's Azure Container Service (ACS) is based around DC/OS. In March 2016, Mesosphere open sourced DC/OS, making it easier than ever to get started.

This chapter will look at using Mesosphere, to manage and deploy Docker-based applications. It will cover deploying, scaling, and upgrading new applications. It will also show how to use the built-in overlay with the load balancing features of Marathon. Finally, the chapter will cover the use of volumes to persist data and how to use a private registry.

This chapter will cover the following topics:

  • Installing Mesos and DC/OS

  • Managing containers and applications...
