Docker Swarm testbed

This repo has been created as a simple vagrant based testbed to aid familiarizing yourself with the new orchestration features starting with docker 1.12.

For a tutorial of the swarm mode have a look at: https://docs.docker.com/engine/swarm/swarm-tutorial/

Prerequisites on the host

• Vagrant (preferably >=1.8.6)
• Ansible >=2.0
• Virtualbox >=5.0 or vagrant-libvirt on kvm + vagrant-sshfs

Usage

Virtualbox

Just do vagrant up. Optionally, if you want to install ansible in a virtualenv: make && source ve/bin/activate and then vagrant up.

Libvirt

make
source ve/bin/activate # Will install vagrant-sshfs
vagrant up

You will end up with 3 vagrant boxes:

Vagrant Machine Name	Docker Role
m01	Manager node
w01	Worker node
w02	Worker node

After vagrant up is done, you should be able to vagrant ssh <machinename> and issue docker node ls to see the swarm nodes.

docker-swarm-visualizer runs on m01 and you can access it on http://192.168.124.100:3000.

And overlay network named net001 will get configured too in case your application "stack" includes components that need to talk to each other.
