Nginx 控制器事件，带有消息“已计划同步”

Question

我已经部署了AWS elb和nginx-controller。我正在使用 nginx 将流量路由到不同的命名空间。当我应用入口资源并描述它时，我得到：

----    ------  ----               ----                      -------
  Normal  Sync    42m (x4 over 72m)  nginx-ingress-controller  Scheduled for sync
  Normal  Sync    42m (x4 over 72m)  nginx-ingress-controller  Scheduled for sync
  Normal  Sync    42m (x4 over 72m)  nginx-ingress-controller  Scheduled for sync
  Normal  Sync    42m (x4 over 72m)  nginx-ingress-controller  Scheduled for sync

我无法联系到主机，但它与其他主机运行良好。

就我而言，将 Nginx 升级到 v1 后，由于领导者选举配置映射的名称发生了变化，我遇到了 Nginx 控制器无法建立领导者的问题。

确保如果您更新 Nginx，也会更新关联的角色权限。
