结论先行：kubesphere-system名称空间下reids宕机重启，会判断是否通过registry-proxy重新拉取镜像，该镜像原本是通过阿里云上拉取，代理上没有出现超时情况，导致失败。
解决方案：删除registry-proxy或修改registry-proxy配置

现象

kubesphere控制台点击登录不跳转

问题排查

1. 查看kubesphere-system空间情况

kubectl get all -n kubesphere-system

发现redis没起来

2. kubesphere控制台模块ks-console，查看日志确认问题是什么引起

kubectl logs <ks-console> -n kubesphere-system

结论：reids没起来导致的kubesphere登录不上

3. 定位reids启动失败原因

由于reids pod没有创建 只能通过事件定位，查看kubesphere-system空间下事件

kubectl get events  -n kubesphere-system

m27s       Warning   FailedCreate        replicaset/redis-57f4b4584b                       Error creating: Internal error occurred: failed calling webhook "registry-proxy.registry-proxy.svc": failed to call webhook: Post "https://registry-proxy.registry-proxy.svc:443/mutate?timeout=3s": dial tcp 10.20.3.39:443: connect: connection refused

失败原因是通过registry-proxy调用错误，卸载registry-proxy，删除registry-proxy命名空间下所有资源，看是否恢复

4. 卸载registry-proxy

卸载参考：https://ketches.cn/registry-proxy/

5. 修改reids副本，重启

kubectl scale deployment redis --replicas=0 -n kubesphere-system
kubectl scale deployment redis --replicas=1 -n kubesphere-system

6. 查看部署情况

kubectl get deployments -n kubesphere-system

7. 再次登录成功

8. registry-proxy用途还是比较大的，采用修改配置解决上述问题

配置参考：https://ketches.cn/registry-proxy/
修改默认配置：excludeNamespaces中添加kubesphere-system

kind: ConfigMap
