There is one version:
This image has docker-1.9.1 since that's what k8s uses. Go version is 1.7.3
This image is to be paired with the kubernetes plugin. To use this image specify it as a pod template and make sure to specify your volume mounts as /var/run/docker.sock. Inside the jenkins job, use "sudo docker <cmd>" to run docker commands. Do note that mounting this image on top of the docker socket lets the job create sibling containers on the underlying docker-engine. In this case it would be the docker engine run by the kubernetes minion.
