In the interim, there is a Docker image under development here interested parties may try: https://github.com/OneBusAway/onebusaway-docker

When the state of this issue changes, we also need to update the docs at https://github.com/OneBusAway/onebusaway-application-modules/wiki/OneBusAway-Quickstart-Guide.
