Question

我正在尝试找到一种在群集上禁用--basic-auth-file的方法。有人可以帮我吗？

您可以直接从/etc/kubernetes/manifests/kube-apiserver.yaml文件中禁用它。例如

apiVersion: v1
kind: Pod
metadata:
  annotations:
    scheduler.alpha.kubernetes.io/critical-pod: ""
  creationTimestamp: null
  labels:
    component: kube-apiserver
    tier: control-plane
  name: kube-apiserver
  namespace: kube-system
spec:
  containers:
  - command:
    - kube-apiserver
    - --basic-auth-file=xxxxx .  <===== Remove this line
    - --authorization-mode=Node,RBAC
    - --advertise-address=xxxxxx
    - --allow-privileged=true
    - --client-ca-file=/etc/kubernetes/pki/ca.crt
    - --cloud-provider=aws
    - --disable-admission-plugins=PersistentVolumeLabel
    - --enable-admission-plugins=NodeRestriction,DefaultStorageClass,NamespaceLifecycle,LimitRanger,ServiceAccount,DefaultTolerationSeconds,MutatingAdmissionWebhook,ValidatingAdmissionWebhook,ResourceQuota
    - --enable-bootstrap-token-auth=true

    - --kubelet-client-key=/etc/kubernetes/pki/apiserver-kubelet-client.key
    - --kubelet-preferred-address-types=InternalIP,ExternalIP,Hostname
    - --proxy-client-cert-file=/etc/kubernetes/pki/front-proxy-client.crt

然后在您的主服务器上重新启动您的kube-apiserver容器

根据您的评论，您正在使用kops部署集群。在kops情况下，您需要添加以下行以禁用--basic-auth-file标志。

kops edit cluster --name <clustername> --state <state_path>

spec:
  kubeAPIServer:
    disableBasicAuth: true

spec 和 kubeAPIServer 可能已经存在于您的集群配置中

要应用更改，您需要运行

kops update cluster --name <clustername> --state <state_path> <--yes>

并进行滚动升级

kops update cluster --name <clustername> --state <state_path> <--yes>

如果您在不使用-yes 的情况下运行命令，它将基本上向您显示要执行的操作，而使用-yes 则将应用更改/滚动集群。

可悲的是，KOPS缺少关于可以在集群配置yaml中使用的选项的文档，我能找到的最好的是它们的API定义： https://github.com/kubernetes/kops/blob/master/pkg/apis/kops/componentconfig.go#L246
