 likely in future releases.
 
-Kubernetes SD configurations allow retrieving scrape targets from
-[Kubernetes'](http://kubernetes.io/) REST API. By default, this discovers
-API servers, nodes, and appropriately annotated services so that metrics from both
-cluster components and deployed applications can be scraped. This will create
-multiple target groups: one for all API servers with each API server as a target, one
-for all nodes with each node as a target, and one for each service containing

 The following meta labels are available on targets during relabeling:
 
-* `__meta_kubernetes_role`: the role of the target: one of `apiserver`, `node`

 as retrieved from the API server.
