I have setup metricbeat-7.5.2 on kubernetes using the instructions available @ kauri. my pod is up and running fine and I am also able to view metrics in kibana.
When I was going through the pod logs I found an error, which states "cannot list resource "replicasets" in API group "apps" at the cluster scope".
