###
# This docker-compose file contains optional MongoDB and MongoDB-writer services
# for Mainflux platform. Since these are optional, this file is dependent of docker-compose file
# from <project_root>/docker. In order to run these optional service, execute command:
# docker-compose -f docker/docker-compose.yml -f docker/addons/mongodb-writer/docker-compose.yml up
# from project root. MongoDB default port (27017) is exposed, so you can use various tools for database
# inspection and data visualization.
