This gist will drive you through creating a Docker 1.12 Swarm cluster (with Swarm mode) on AWS infrastructure.

Prerequisites

You need a few things already prepared in order to get started. You need at least Docker 1.12 set up. I was using the stable version of Docker for mac for preparing this guide.

$ docker --version
Docker version 1.12.0, build 8eab29e

You also need Docker machine installed.

docker-machine import/export

Script to import and export docker-machine configurations to sync between hosts/collaborators

Export (on host A)

$ docker-machine ls

Install dnsmasq using Homebrew. Edit the dnsmasq.conf file (Homebrew will tell you where to put it) to contain:

address=/.dev/127.0.0.1
listen-address=127.0.0.1

Then make sure Dnsmasq is running (again follow Homebrew instructions).

Create the /etc/resolver/dev directory (using root) if it doesn't exist yet and create a resolver for .dev:

  user: vagrant
  gather_facts: false
  sudo: true

  tasks:
    - name: Ensure gcc installed
      yum:  name=gcc state=present
