kubernetes: how to set "top node" and "top pod" permissions?
Thanks to arghya-sadhu's comments on stackoverflow, I've got it working:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: get-pod-and-node
  labels:
    rbac.authorization.k8s.io/aggregate-to-view: "true"
rules:
- apiGroups: ["metrics.k8s.io"]
  resources: ["pods", "nodes"]
  verbs: ["get", "watch", "list"]


(I'm aggregating to the standard 'view' role)
