Question

我正在EKS中构建一个服务，该服务具有两个部署，两个服务（NodePort）和一个入口。

我正在使用aws-alb-ingress-controller。
当我运行kubectl port-forward POD 8080:80时，它确实向我显示了我正在工作的豆荚。
当我用alb查看生成的端点时，出现502错误。
当我查看目标组的已注册目标时，看到消息，运行状况检查失败，并显示以下代码：[502]

这是我完整的字母。

Answer 1

我不知道为什么，但是事实证明赋予入口的标签必须唯一。

当我将标签从“ example-app”更改为“ example-app-ingress”时，它开始工作。

为什么在针对EKS托管服务的ALB端点上出现502错误
