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.

In this step we'll create a swarm cluster from two nodes. You should've received access to two nodes in AWS.

1. SSH in to the first node: ssh -i docker_demo.pem ubuntu@IP1
2. Figure out the internal IP address of the node: ifconfig and check the eth0 address (10.0....)
3. Initialize the Swarm cluster: `docker swarm init --listen-addr INTERNAL_IP --advertise-addr INTERNAL_IP
4. Open a new tab and SSH to the other node: ssh -i docker_demo.pem ubuntu@IP2
5. Check the internal IP of that node: ifconfig and eth0
6. Join to the cluster with the command the previous command printed out. Before executing the command, you need to the extend it with the --listen-addr and --advertise-addr parameters (using the internal IP of the second node): docker swarm join TOKEN --listen-addr 10.0.... --advertise-addr 10.0..... node1...
7. Get back to the first node and verify the results: docker node ls
