Native Docker Clustering with Swarm

By: Fabrizio Soppelsa, Chanwit Kaewkasi

Overview of this book

Docker Swarm serves as one of the crucial components of the Docker ecosystem and offers a native solution for you to orchestrate containers. It’s turning out to be one of the preferred choices for Docker clustering thanks to its recent improvements. This book covers Swarm, Swarm Mode, and SwarmKit. It gives you a guided tour on how Swarm works and how to work with Swarm. It describes how to set up local test installations and then moves to huge distributed infrastructures. You will be shown how Swarm works internally, what’s new in Swarmkit, how to automate big Swarm deployments, and how to configure and operate a Swarm cluster on the public and private cloud. This book will teach you how to meet the challenge of deploying massive production-ready applications and a huge number of containers on Swarm. You'll also cover advanced topics that include volumes, scheduling, a Libnetwork deep dive, security, and platform scalability.

Tools


With Swarm Mode, we can easily design a production-grade cluster.

The principles and architecture we're illustrating here are important in general and give a foundation on how to architect production installations, regardless of the tools. However, from a practical point of view, the tools to use are also important.

At the time of writing this book, Docker Machine was not the ideal single tool to use for large swarms setups, so we're demonstrating our production-scale deployments with a tool born alongside with this book that we already introduced in Chapter 1, Welcome to Docker Swarm: belt (https://github.com/chanwit/belt). We'll use it in conjunction with Docker Machine, Docker Networking, and the DigitalOcean's doctl command.

In Chapter 5, Administer a Swarm Cluster you'll learn how it's possible to automate the creation of Swarms; especially, how to quickly join a massive number of workers with scripts and other mechanisms, such as Ansible.
