没有可用于服务\“ kubernetes-dashboard \”的端点

我正在尝试遵循GitHub-kubernetes / dashboard：Kubernetes集群的通用Web UI。

部署/访问：

# export KUBECONFIG=/etc/kubernetes/admin.conf
# kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/master/src/deploy/recommended/kubernetes-dashboard.yaml
secret/kubernetes-dashboard-certs created
serviceaccount/kubernetes-dashboard created
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
deployment.apps/kubernetes-dashboard created
service/kubernetes-dashboard created
# kubectl proxy
Starting to serve on 127.0.0.1:8001

卷曲：

# curl http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/
{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {

  },
  "status": "Failure",
  "message": "no endpoints available for service \"kubernetes-dashboard\"",
  "reason": "ServiceUnavailable",
  "code": 503
}# 

请指教。

看来您是在尝试利用Kubernetes进行部署，kubeadm但是已经跳过了安装Pod Network Add-on（CNI）的步骤。注意警告：

必须在任何应用程序之前部署网络。另外，在安装网络之前，CoreDNS将不会启动。kubeadm仅支持基于容器网络接口（CNI）的网络（不支持kubenet）。

完成此操作后，CoreDNS Pod应该会正常运行。可以通过以下方式验证： kubectl -n kube-system -l=k8s-app=kube-dns get pods

然后，kubernetes-dashboard豆荚也应该健康。
