I thought the standard design pattern for that was zones.
say your cloud is cloud.example.com
so SRV for cloud.example.com would be keystone public
SRV for _compute._pub_endpoints.cloud.example.com -> compute public endpoint
SRV for _compute._priv_endpoints.cloud.example.com -> compute private
endpoint (and btw you can use split views to hide that from the
outside world)

SRV for _network._pub_endpoints.cloud.example.com -> openstack network
public endpoint
etc.


E.g. known, solved thing, nothing to see here, move along.
