# Initialize and start the MongoDB server in a docker container.  This script
# is run only once in a newly configured docker host.  Currently, the docker
# host is a single openstack machine instance.  This script assumes that the
# docker host's filesystem has been setup and both docker and the QMCDB
# software have been installed.
