I installed Docker on my Macbook, it was quite easy following the directions on the Docker website.

I played around a little and located an SLC docker image. In a fresh terminal:

->boot2docker init
->boot2docker start
->export DOCKER_TLS_VERIFY=1
->export DOCKER_HOST=tcp://192.168.59.103:2376
->export DOCKER_CERT_PATH=/Users/childers/.boot2docker/certs/boot2docker-vm
->docker search slc6
