CoreOS-Vagrant Cluster for OS X

CoreOS-Vagrant Cluster GUI for Mac OS X is a Mac Status bar App which works like a wrapper around the coreos-vagrant command line tool and bootstraps CoreOS cluster with one control (etcd) and two worker machines. Flannel network is set too.

CoreOS is a Linux distribution made specifically to run Docker containers. CoreOS-Vagrant is made to run on VirtualBox and VMWare VMs.
