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

  • 我正在使用 aws-alb-ingress-controller。
  • 当我运行时kubectl port-forward POD 8080:80 ，它确实向我展示了我的工作 pod。
  • 当我查看 alb 生成的端点时，我得到 502 错误。
  • 当我查看目标组的已注册目标时，我看到消息，运行状况检查失败并显示以下代码：[502]

这是我完整的 yaml。

我不知道为什么，但事实证明给予 ingress 的标签必须是唯一的。

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