CoreOS

CoreOS VM for OS X (coreos-machine) is a Mac Status bar App which works like a wrapper around the corectl command line tool (it makes easier to control xhyve based VMs).

The best use case of this App is to allow to build/test Docker and rkt images localy. You can use included Docker Registry v2 (Go based and compiled for OS X) to store your Docker images and share with Kubernetes Apps.
