Kubernetes版本v1.17.3 kubesphere 3.11 默认用户登录失败 - KubeSphere 开发者社区

2. 问题日志： 

2.1问题排查方法 ： 

用户无法登录

http://192.168.56.100:30880/

 2.2查看用户状态 

 kubectl get users

[root@k8s-node1 ~]# kubectl get users
NAME    EMAIL                 STATUS
admin   admin@kubesphere.io  

正常的应该是： 

 

2.3 检查 ks-controller-manager 是否正常运行，是否有异常日志：

kubectl -n kubesphere-system logs -l app=ks-controller-manager

kubectl -n kubesphere-system logs -l app=ks-controller-manager

3. 问题解决 

参考： 在修改密码和添加用户时报错 - KubeSphere 开发者社区

set ks-controller-manage hostNetwork: true

kubectl delete validatingwebhookconfigurations.admissionregistration.k8s.io users.iam.kubesphere.io

问题解决日志： 最后reboot 重启
