無法訪問 Kubernetes 儀表板面板（503 沒有可用的端點）

Question

我在放置 kubernetes 儀表板時遇到問題。 看起來它只是達到待處理狀態。 我在事件中找到了有關由於 docker 中的其他圖像而釋放內存的問題的信息。 我正在尋找解決方案，我無法關閉當前圖像。

輸出：

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

通過執行此 URL 授予對儀表板的訪問權限：

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

注意這部分：

/https:kubernetes-dashboard:https/

不添加 https 它不起作用 - 您將始終no endpoints available for service kubernetes-dashboard 。

請參閱此處自述文件中的工作鏈接： kubernetes-dashboard-issue-endpoints 。

看一看： dashboard-endpoints-issue endpoints-available-for-service-kubernetes-dashboard 、 dashboard-endpoints 、 kubernetes-503-no-endpoints-available 。

@PKosiba，不，這不是磁盤問題，這基本上意味着您在集群中的節點/機器上存在所謂的污點和容忍度，這反過來意味着 Kubernetes 調度程序無法在任何現有節點上調度您的 pod，因為它沒有相應的污點，基本上你的節點上有一些東西說“不要在這個沒有這個標簽磁盤壓力的節點上安排任何事情”：
