Hi Sage, The automated tool Cepheus https://github.com/cepheus-io/cepheus does this with ceph-chef. It's based on json data for a given environment. It uses Chef and Ansible. If someone wanted to break out the haproxy (ADC) portion into a package then it has a good model for HAProxy they could look at. Originally created due to the need for our own software LB solution over a hardware LB. It also supports keep-alived and bird (BGP).
