Looking for label examples/guides

I am reading the labels pages, but I’m not really seeing any examples(or my eyes are just glazed over from working on this stuff all day. I am trying to do something simple. I want to set my loadbalancer to only run on one specific host.

What label do I give my host?
What code do I put in my docker-compose and rancher compose?

Is there a guide that goes in to this in more depth?

Solved: I don’t know how I missed it:

io.rancher.scheduler.affinity:host_label: lb=true

We try our best to give examples of how to do everything, but sometimes it can be a bit hidden.

Host label: http://docs.rancher.com/rancher/rancher-ui/infrastructure/hosts/#host-labels
Docker-compose.yml information: http://docs.rancher.com/rancher/rancher-compose/scheduling/#finding-hosts-with-host-labels
