kubernetes - Kubernetes RBAC默认用户

Question

我目前正在读RBAC，正在使用启用了本地Kubernetes集群的Docker For Desktop。

如果我运行kubectl auth can-i get pods，默认情况下使用哪个用户，组或服务帐户？

是否像这样的电话:
kubectl auth can-i get pods --as docker-for-desktop --as-group system:serviceaccounts？
kubectl config view显示:

contexts:
- context:
    cluster: docker-for-desktop-cluster
    namespace: default
    user: docker-for-desktop
  name: docker-for-desktop
...
users:
- name: docker-for-desktop
  user:
    client-certificate-data: REDACTED
    client-key-data: REDACTED

但是只需调用kubectl auth can-i get pods --as docker-for-desktop即可返回NO。

谢谢，

回答你的问题

If I run kubectl auth can-i get pods which user or group or serviceaccount is used by default?

正如您可以在Configure Service Accounts for Pods上阅读的那样:

When you (a human) access the cluster (for example, using kubectl), you are authenticated by the apiserver as a particular User Account (currently this is usually admin, unless your cluster administrator has customized your cluster). Processes in containers inside pods can also contact the apiserver. When they do, they are authenticated as a particular Service Account (for example, default).

您可以使用kubectl get serviceaccount来查看集群中设置了哪些serviceaccounts。
尝试检查可用的上下文，然后切换到所需的上下文:
kubectl config get-contextskubectl config use-context docker-for-desktop
如果您遇到缺少Role的问题，请检查Referring to Resources以将其正确设置为docker-for-desktop
