如何为 kubernetes 桌面配置简单的 login/pass 身份验证 UI

Question

我是 kubernetes 的新手，我只是通过 kubeadm 和运行仪表板 UI 安装 kubernetes，但无法配置对它的访问。在文档之后，我将 --basic-auth-file=/etc/kubernetes/auth.csv 行添加到 /etc/kubernetes/manifests/kube-apiserver.yaml，创建文件并放入一个字符串，如 pass,admin,admin。但在那之后 api 服务器崩溃并在删除此字符串并重新启动服务器后恢复正常。我如何才能将此参数传递给 api 服务器而不 api 服务器崩溃，也许还需要从该文件中添加或删除其他内容？这是我的

您的基本身份验证文件 /etc/kubernetes/auth.csv 在 kube-apiserver pod 的容器中不可用。它应该挂载到 pod 的容器以及证书文件夹。只需将它添加到 volumes 和 volumeMounts 部分：

    volumeMounts:
    - mountPath: /etc/kubernetes/auth.csv
      name: kubernetes-dashboard
      readOnly: true
  volumes:
  - hostPath:
      path: /etc/kubernetes/auth.csv
    name: kubernetes-dashboard
