Vagrant Docker Swarm

This project provides a Vagrantfile to set up a Docker swarm with a manager and multiple worker nodes. The number of worker nodes can be set using the environment variable DOCKER_WORKER_COUNT.

Prerequisites

Vagrant

Starting A Docker Swarm

To set-up and start a swarm with one manager and two worker nodes:

$ vagrant up

To change the number of worker nodes to three:

$ export DOCKER_WORKER_COUNT=3 
$ vagrant up
