Question

我有一个简单的节点api服务，mongo服务和负载平衡器。

我正在尝试使用kubernetes部署我的应用程序，运行命令时出现以下错误。

- kubectl describe ing -n my-service

警告错误5秒（x2超过8秒）aws-alb-ingress-controller错误实例化负载均衡器：my-service-api服务类型不正确 NodePort和目标类型是实例

有人可以告诉我我在这里做错了吗，谢谢。

您的my-service-api服务类型似乎是“ LoadBalancer”，并且您需要使用“ NodePort” 才能将instance用于alb.ingress.kubernetes.io/target-type: < / p>
