Please try out the excellent article Fun with Docker Swarm and Excellent working example on Swarm. Using the knowledge gained from these articles, I was able to get my swarm up and running on my windows 10 box using VirtualBox.
Note: Please make sure that the Docker Toolbox installation and virtual box are properly installed on windows. I have used the windows 10 and it worked well.
