Kubernetes 仪表板一直挂起消息：没有可用于服务的端点 "kubernetes-dashboard"

Question

大家好，我需要一些帮助来让仪表板正常工作。我的仪表板 pod 的状态为 "Pending"，如果我对 http://127.0.0.1:8080/api/v1/proxy/namespaces/kube-system/services/kubernetes-dashboard 进行 curl 调用，则会得到以下结果：

"no endpoints available for service \"kubernetes-dashboard\""

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

全部pods

服务配置：

我也试着找了一些日志：

core@helena-coreos ~ $ ./kubectl logs kubernetes-dashboard-1775839595-1h0lt --namespace=kube-system
core@helena-coreos ~ $

我真的很难弄清楚为什么事情悬而未决

已经提前谢谢了。

Answer 1

您没有调度程序运行，因此它无法调度任何容器。

Answer 2

另一种可能是集群中没有资源，调度程序无法调度仪表板UI。如果这是真的，您可以在集群事件中看到这一点 (kubectl get events --namespace=kube-system)。
