如何为kubernetes桌面UI配置简单的登录/通过身份验证

Question

我是kubernetes的新手，我只是通过kubeadm安装kubernetes并运行仪表板UI，但无法配置对它的访问。在文档之后，我将行添加--basic- auth-file=/etc/kubernetes/auth.csv到/etc/kubernetes/manifests/kube-
apiserver.yaml，创建文件并放入一个字符串，如pass,admin,admin。但是在该api服务器崩溃之后，删除此字符串并重新启动服务器后，它又恢复了正常。如何在不使api服务器崩溃的情况下将该参数传递给api服务器，也许还有其他需要从该文件中添加或删除？这是我的

kube-apiserver.yaml

您的基本身份验证文件/etc/kubernetes/auth.csv在kube-apiserver
pod容器内不可用。应该将其安装到Pod的容器以及证书文件夹中。只需将其添加到volume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
