Question

我是Kubernetes的新手。我正在尝试使用kops在AWS上设置Kubernetes集群。我成功地设置了集群。但是，我无法访问仪表板UI。（https://kubernetes.io/docs/tasks/access-application-cluster/web-ui-dashboard/#accessing-the-dashboard-ui）

当我访问主节点时，我看到以下错误：

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

我将仪表板的状态视为CrashLoopBackOff。（请注意：我已删除以下日志中其他pod的名称）

~$ kubectl get pods --all-namespaces
NAMESPACE     NAME                                                    READY     STATUS             RESTARTS   AGE

$ kubectl logs kubernetes-dashboard-4167803980-vnx3k --namespace=kube-system

我真诚地感谢任何帮助/建议让仪表板运行。提前谢谢！

您使用的是最新的信息中心，看起来需要SSL证书。尝试使用1.6.3，它将无需SSL证书。

我在我的群集中运行此版本。

kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.6.3/src/deploy/kubernetes-dashboard.yaml

安装信息中心的Helm命令

kubectl create clusterrolebinding add-on-cluster-admin --clusterrole=cluster-admin  --serviceaccount=kube-system:default
helm install stable/kubernetes-dashboard  --name kubernetes-dashboard --namespace  kube-system --debug
helm install stable/heapster  --namespace  kube-system
