It doesn't have to be FQDN. Here's how I run Kafka in a container: docker run --name st-kafka -p 2181:2181 -p 9092:9092 -e ADVERTISED_HOST=`docker-machine ip dev-st` -e ADVERTISED_PORT=9092 -d spotify/kafka
And then you have access to Kafka on the docker host VM from any other machine. BTW I use Spotify's image since it contains both ZK and Kafka, but I think the latest version they built is 0.8.2.1, so you might have to build the new image yourself if you need 0.9, but that's trivial to do.
