People want to look at the LMA stack but can’t remember the IP, DNS name, port or name of the thing they want to look at. Homer[1] is static web server and provides one stop shop UI, which a single URL and be able to click on a link to get to the LMA stack and other sites (like maas, other support portal). The application is registered to Homer dashboard via registration relation.

By adding registration relation in openstack dashboard charm, we can register horizon in Homer dashboard after creating relation between openstack-dashboard charm and Homer charm
