Being able to set HAPROXY_0_VHOST to the mesos-dns name and having everything just magically work is a pretty fantastic user experience however. Especially for users who might need to talk to SysAdmin teams to manually change DNS. Any alternatives? We have marathon-lb running in a container with keepalived on every mesos agent. That way users who want static names can ask to have a name created which is just a cname to the vip. Otherwise they can use the mesos-dns name and manage the entire lifecycle themselves.
