Native Docker Clustering with Swarm

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.

Swarm3k


Swarm3k was the second collaborative project trying to form a very large Docker cluster with the Swarm mode. It was fired up on 28th October 2016 with more than 50 individuals and companies joining this project.

Sematext was one of the very first companies that offered to help us by offering their Docker monitoring and logging solution. They became the official monitoring system for Swarm3k. Stefan, Otis, and their team provided wonderful support for us from the very beginning.

Sematext Dashboard

Sematext is the one and only Docker monitoring company that allows us to deploy the monitoring agents as the global Docker service at the moment. This deployment model provides for a greatly simplified monitoring process.

Swarm3k Setup and Workload

We aimed at 3000 nodes, but in the end, we successfully formed a working, geographically distributed 4,700-node Docker Swarm cluster.

The managers' specifications were high-mem 128GB DigitalOcean nodes in the same Data Center, each with 16 vCores.
