### kube-rbac-proxy
You can enable `kube-state-metrics` endpoint protection using `kube-rbac-proxy`. By setting `kubeRBACProxy.enabled: true`, this chart will deploy one RBAC proxy container per endpoint (metrics & telemetry).
To authorize access, authenticate your requests (via a `ServiceAccount` for example) with a `ClusterRole` attached such as:
```yaml
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
name: kube-state-metrics-read
rules:
- apiGroups: [ "" ]
resources: ["services/kube-state-metrics"]
verbs:
- get
```
See [kube-rbac-proxy examples](https://github.com/brancz/kube-rbac-proxy/tree/master/examples/resource-attributes) for more details.
