问题：运行docker-for-mac＆kubernetes，命令kubectl get pods -namespace=kube-system未列出预期的Pod。
使用kubernetes和docker-for-mac进行实验。完成初始设置后，我希望以下命令的输出列出多个Pod（例如etcd pod和kube-proxy pod等）
╰─$ kubectl get pods -namespace=kube-system
No resources found.
我可以验证实际的容器本身是否在docker container ls的输出下运行
╰─$ docker container ls

您使用的命令不正确，应该使用：
kubectl get pods --namespace=kube-system
或
kubectl get pods -n kube-system
