创建部署问题时，请参考下面模板，你提供的信息越多，越容易及时获得解答。如果未按模板创建问题，管理员有权关闭问题。
确保帖子格式清晰易读，用 markdown code block 语法格式化代码块。
你只花一分钟创建的问题，不能指望别人花上半个小时给你解答。
操作系统信息
例如：虚拟机/物理机，Centos7.5/Ubuntu18.04，4C/8G
Kubernetes版本信息
将 kubectl version 命令执行结果贴在下方
容器运行时
将 docker version / crictl version / nerdctl version 结果贴在下方
KubeSphere版本信息
例如：v2.1.1/v3.0.0。离线安装还是在线安装。在已有K8s上安装还是使用kk安装。
问题是什么
报错日志是什么，最好有截图。

The reset process does not clean CNI configuration. To do so, you must remove /etc/cni/net.d

The reset process does not reset or clean up iptables rules or IPVS tables.
If you wish to reset iptables, you must do so manually by using the "iptables" command.

If your cluster was setup to utilize IPVS, run ipvsadm --clear (or similar)
to reset your system's IPVS tables.

The reset process does not clean your kubeconfig files and you must remove them manually.
Please, check the contents of the $HOME/.kube/config file.

[reset] Deleting contents of stateful directories: [/var/lib/dockershim /var/run/kubernetes /var/lib/cni]

The reset process does not clean CNI configuration. To do so, you must remove /etc/cni/net.d

The reset process does not reset or clean up iptables rules or IPVS tables.
If you wish to reset iptables, you must do so manually by using the "iptables" command.

If your cluster was setup to utilize IPVS, run ipvsadm --clear (or similar)
to reset your system's IPVS tables.

The reset process does not clean your kubeconfig files and you must remove them manually.
Please, check the contents of the $HOME/.kube/config file.
