Dockerfile - comment misused VOLUME instructions

Browse source 
Issuing a VOLUME instruction in a production Dockerfile requires the Docker engine to create a volume whether or not it is mapped to the host or a named volume. Neither of these paths have data that needs to be persisted for production use, so their inclusion under a typical `docker run` example forces the engine to create extraneous volumes which quickly become orphaned whenever the container is recreated.
