Eu tenho um novo cluster k8s no gke.
Sempre que eu corro kubectl top node gke-data-custom-vm-6-25-0cbae9b9-hrkc
eu recebo
Error from server (NotFound): the server could not find the requested resource (get services http:heapster:)
Ao mesmo tempo, tenho este serviço:
> kubectl -n kube-system get services
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
default-http-backend NodePort 10.11.241.20 <none> 80:32688/TCP 59d
heapster ClusterIP 10.11.245.182 <none> 80/TCP 59d
kube-dns ClusterIP 10.11.240.10 <none> 53/UDP,53/TCP 59d
metrics-server ClusterIP 10.11.249.26 <none> 443/TCP 59d
e um pod com heapster está em execução (e posso ver que foi reiniciado muitas vezes)
kubectl -n kube-system get pods

No entanto, posso ver nos logs do contêiner heapster-nanny alguns erros:

Alguma informação adicional que devo fornecer?
