i am new to kubernetes. i have just followed this guide and have a vagrant/kubernetes cluster: https://coreos.com/kubernetes/docs/latest/kubernetes-on-vagrant.html

i was interested viewing the ui, so i followed the instructions here: http://kubernetes.io/docs/user-guide/ui/#deploying-the-dashboard-ui

$ kubectl proxy
Starting to serve on 127.0.0.1:8001

upon browsing to the above IP:PORT, <h3>Unauthorized</h3> is served. so, i suffix /ui to the URI, and we get:

// 127.0.0.1:8001/ui redirected to http://localhost:8001/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard
{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {},
  "status": "Failure",
  "message": "no endpoints available for service \"kubernetes-dashboard\"",
  "reason": "ServiceUnavailable",
  "code": 503
}

perhaps relevant is:

$ kubectl cluster-info
Kubernetes master is running at https://172.17.4.101:443
Heapster is running at https://172.17.4.101:443/api/v1/proxy/namespaces/kube-system/services/heapster
KubeDNS is running at https://172.17.4.101:443/api/v1/proxy/namespaces/kube-system/services/kube-dns
kubernetes-dashboard is running at https://172.17.4.101:443/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard

$ kubectl get services
NAME         CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   10.3.0.1     <none>        443/TCP   36m

i saw another SO thread, Kubernetes dashboard keeps pending with message: no endpoints available for service "kubernetes-dashboard", and discovered get pods and describe pod <pod-name> --namespace=kube-system.

so, i ran kubectl describe pod kubernetes-dashboard-3543765157-94gj9 --namespace="kube-system" which yielded: https://gist.github.com/cdaringe/b972bf5a95c9f2a7cb8386ef6bf2252b
