Kafka in Docker in Vagrant

I'm using this Vagrantfile to run Kafka on a Windows 8.1 laptop for development purposes.

It runs the ultra-lightweight boot2docker Linux, then uses Vagrant's Docker provisioning support to spin up ZooKeeper and Kafka.

The fun bits to work out were:

• You need to forward the ports on both Vagrant (lines 13 & 14) and Docker (the -p flag), so you can access the instance from Windows using localhost:9092
