Current versions of Docker include Swarm mode for natively managing a cluster of Docker Engines called a swarm. Use the Docker CLI to create a swarm, deploy application services to a swarm, and manage swarm behavior.
Make sure the Docker Engine daemon is started on the host machines. Open a terminal and ssh into the machine where you want to run your manager node. This tutorial uses a machine named manager1. Run the following command to create a new swarm: $ docker swarm init --advertise-addr <MANAGER-IP>.
swarm is a simple tool which controls a cluster of Docker hosts and exposes it as a single "virtual" host.
This tutorial introduces you to the features of Docker Engine Swarm mode. You may want to familiarize yourself with the key concepts before you begin. The tutorial guides you through: Initializing a cluster of Docker Engines in swarm mode; Adding nodes to the swarm; Deploying application services to the swarm
Docker Swarm is native clustering for Docker. It turns a pool of Docker hosts into a single, virtual host. Swarm serves the standard Docker API, so any tool which already communicates with a Docker daemon can use Swarm to transparently scale to multiple hosts: Dokku, Compose, Krane, Flynn, Deis, DockerUI, Shipyard, Drone, Jenkins... and, of ...

Jul 29, 2021 · Swarm Mode is Docker's built-in orchestration system for scaling containers across a cluster of physical machines. Multiple independent clients running Docker Engine pool their resources, forming a swarm.
