Where does the $cluster variable come from?

[zachfi]

Good day,

I see a few tickets about this, but none seem to apply to me. I've got a single cluster and am trying to use this mixin, but the $cluster variable is empty due to the kube_pod_info metric missing the label for cluster. How do I add that label to my cluster so that the dashboards will work? Is that in the prometheus scrape configs, or the global config, or something that is in $._config of this mixin?

Take a look at https://github.com/kubernetes-monitoring/kubernetes-mixin/blob/master/config.libsonnet#L84

Is there a more general example? Which section does it go to?
