老师，在安装heapster时
kubectl get pods -n kube-system执行成果

执行kubectl create -f rbac/heapster-rbac.yaml成功
clusterrolebinding.rbac.authorization.k8s.io/heapster created
但是执行kubectl top node返回
error: metrics not available yet
同时发现在新开的ssh窗口执行：kubectl get pods -n kube-system，返回如下：
The connection to the server localhost:8080 was refused - did you specify the right host or port?
怀疑是dns有问题，请问应该如何查找问题，如何解决呢？

我想这里有两个问题：
1. metrics not available yet
- heapster安装后，需要等待一段时间才会有metrics数据进来。这之前都会返回"metrics not available yet"的提示信息2. kubectl get pods命令失败
- 你可以看一下当前节点上的KUBECONFIG是否配置正确了。从你报错的日志来看，应该是没有正确配置KUBECONFIG，这样kubectl默认通过localhost:8080端口访问apiserver的insecure port012018-10-08
