访问http://121.201.29.62:8080/ui时报错：

{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {},
  "status": "Failure",
  "message": "no endpoints available for service \"kubernetes-dashboard\"",
  "reason": "ServiceUnavailable",
  "code": 503
}

如下图

不清楚是什么原因，查下dashboard pod的状况

[root@i-gocqtxn7 ~]# ./kubectl get pods --namespace kube-system
NAME                                    READY     STATUS              RESTARTS   AGE
kubernetes-dashboard-2131979702-3r49y   0/1       ContainerCreating   0          6m

[root@i-gocqtxn7 ~]# ./kubectl describe pod kubernetes-dashboard-2131979702-3r49y  --namespace kube-system
Name: kubernetes-dashboard-2131979702-3r49y

解决问题：

docker pull lhcalibur/pause-amd64
docker tag lhcalibur/pause-amd64:latest gcr.io/google_containers/pause-amd64:3.0
