Dump a specific Database

mongodump --db my_db --out ./my_dump_folder

Use --db in case we run the command from inside the /my_dump_folder folder (cd my_dump_folder). Use --drop to drop the Database before restore it.

mongorestore --drop --db my_db .

The flah -P is optional in case need to pass a specific PORT.
