           -v <DATA_DIRECTORY>:/var/lib/mongodb \

• DB_UID (Optional, default: 1500): user UID that mongo should use to store data and run itself. You can set it to your own UID to have a simpler dev environment. Just add -e DB_UID=`id -u` before the -v flag.

A database with the same name as $DB_USER will be created, the user $DB_USER will be available to connect to it.
