cluster-info中没有Dashboard

$ kubectl cluster-info
Kubernetes master is running at https://192.168.205.10:6443
KubeDNS is running at https://192.168.205.10:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

To further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

这个是什么原因呢？就是namespace的移动导致的吗？

必须是有 kubernetes.io/cluster-service label 的 service 才可以显示到 cluster-info 中。
