Kubernetes 仪表板 - 服务不可用(503 错误)
Kubernetes dashboard - ServiceUnavailable (503 error)
我是 Kubernetes 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
}
我看到仪表板的状态为 CrashLoopBackOff。 (请注意:我已经删除了以下日志中其他pods的名字)
~$ kubectl get pods --all-namespaces

非常感谢任何 help/suggestions 获得仪表板 运行。提前致谢!
您使用的是最新的仪表板,看起来需要 SSL 证书。尝试使用 1.6.3 它将在没有 SSL 证书的情况下工作。
我在我的集群中 运行 这个版本。
kubectl create -f https://raw.githubusercontent.com/kubernetes/dashboard/v1.6.3/src/deploy/kubernetes-dashboard.yaml
安装仪表板的 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
