KubeSphere版本信息
Kubesphere 3.2.0 all-in-one安装
Kubernetes 1.21.5
问题是什么
安装后Kubesphere， 下一步我的计划是要创建网关：
- 青云上创建一个负载均衡器，
- kubesphere中安装qingcloud-cloud-controller-manager,
- 在Kubesphere中创建集群网关（或者项目网关）
事情出在第2步：安装qingcloud-cloud-controller-manager, 我按照这里的步骤都安装了（https://github.com/yunify/qingcloud-cloud-controller-manager）一切正常，可到了启动后的POD中看，发现了错误：
我的问题其实有两个：
- 怎么修复这个POD中的错误？
- 我现在已有kubesphere,虽然在青云的机器上，但不是QKE。 我要为kubesphere创建集群网关，上述的理解对么？ 是必须要创建一个额外的青云负载均衡器？ 创建这个负载均衡器有什么要求么，比如是否需要增加监听，为监听添加后端之类的？
