如果我在重启后使用 kubectl 命令，我会收到错误消息。xxxx: 6443 was denied - 你指定了正确的主机或端口吗？
如果我用 docker ps 检查我的容器，kube-apiserver 和 kube-scheduler 会打开和关闭。
为什么会这样？
root@taeil-linux:/etc/systemd/system/kubelet.service.d# cd
root@taeil-linux:~# kubectl get nodes
The connection to the server 10.0.0.152:6443 was refused - did you specify the right host or port?
