Docker: gliderlabs/alpine with runit
Docker alpine & runit image built on gliderlabs/alpine Linux micro OS with the final image size of ~6 MB vs. 100+ MB compared to the Ubuntu / Debian equivalent. It's intended to be used as a base image for building final app images ready for deployment.
Pull or build the image yourself and run it. Before you do that you'll need to configure runit and your services ready for "dockerization".
