无法访问Kubernetes仪表板面板503没有可用的端点

问题描述

我在安装kubernetes仪表板时遇到问题。看起来它只是达到待处理状态。我在事件中找到有关由于Docker中的其他映像而导致释放内存的问题的信息。我正在寻找解决方案，无法关闭当前图像。

输出：

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

解决方法

通过执行以下URL授予对仪表板的访问权限：

http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:https/proxy/

注意此部分：

/https:kubernetes-dashboard:https/

如果不添加https，它将不起作用-您将始终得到no endpoints available for service kubernetes-dashboard。

在此处查看自述文件中的工作链接：kubernetes-dashboard-issue-endpoints。

看看：dashboard-endpoints-issue endpoints-available-for-service-kubernetes-dashboard，dashboard-endpoints，kubernetes-503-no-endpoints-available。

@PKosiba，不，这不是磁盘问题，这基本上意味着您在集群中的节点/机器上具有所谓的污点和容忍度，这又意味着Kubernetes调度程序无法将Pod调度在任何一个现有节点，因为它没有相应的异味，基本上，您的节点上会有一些东西说“不要在该节点上调度没有此标签disk-pressure的任何东西”：
