kubernetes errors

Failed to get kubernetes address: No kubernetes source found

it seems because deploy/1.8+/metrics-server-deployment.yaml doesn’t have any options.

I’ve started metrics-server by adding “source” option referenced from https://github.com/kubernetes/heapster/blob/master/deploy/kube-config/google/heapster.yaml

failed to get cpu utilization: missing request for cpu on container

原因：定义pod的时候，没有设置resources，HPA取不到CPU当前值

resources:
  requests:
    memory: "64Mi"
    cpu: "25m"
  limits:
    memory: "128Mi"
    cpu: "50m"
