-All the interactions between Holmes and other ONAP components are routed by MSB. In order to register Holmes itself to MSB, the users have to specify the IP address of the host using the ``HOST_IP`` variable. Please note that the ``HOST_IP`` should be the IP address of the host, rather than the IP address of the containers (of which the IP address is allocated by the docker daemon).
