kubectl top nodes gives :
Error from server (InternalError): an error on the server ("unknown") has prevented the request from succeeding (get services http:heapster:)
docker logs 66f3b69cb985 on the node gives :
E0729 11:16:36.622691 7 reflector.go:190] k8s.io/heapster/metrics/util/util.go:51: Failed to list *v1.Node: Get https://kubernetes.default/api/v1/nodes?resourceVersion=0: dial tcp: lookup kubernetes.default on 10.96.0.10:53: dial udp 10.96.0.10:53: connect: network is unreachable
Appreciate any help to resolve this.
