positive.code: 
  The management-api image provides a set of environment variables which could be used to tune your container. Because mongoDB is our default repository, you could replace default mongoDB address (`MONGO_DEFAULT_HOST:MONGO_DEFAULT_PORT`) by the one you provide (`MONGO_HOST:MONGO_PORT`).
  
  Because this image is used in our demo, another variable is provided : `check_links`.
  If you set it to true, the container will wait until mongoDB is reachable inside the container.
  And only after that, the management-api will start.
