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。
