Hi All,

After installed Kubernetes. I am unable to access the Dashboard. the moment 
when I hit the master ip :8080/ui in the browser, below is output we are 
getting


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


Also unable to download the  kubectl create -f 
https://rawgit.com/kubernetes/dashboard/master/src/deploy/kubernetes-dashboard.yaml
  file

output: [root@kubernetesmaster ~]# kubectl create -f
