Reveal Pod Overview Metrics in Tectonic Console

Resource utilization graphs in Tectonic Console may appear empty to users on initial login. This is due to rbac restrictions which prevent users from accessing the Prometheus service/endpoint. The following ClusterRole can be used to reveal the metrics:

kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
 name: view-dashboard
rules:
 - verbs:
     - proxy
   apiGroups:
     - ''
   resources:
     - endpoints
     - services
   resourceNames:
     - 'prometheus:9090'

After creating this role bind the role to a user or group object. Below is an example of binding this to a group called `users`. This group is not a default. The group may be different or you may need to bind this to only a user object.
