aws-application-load-balancer - 基于 ALB 入口 Controller 路径的路由

Question

我已经使用基于路径的路由部署了 ALB 入口 Controller ，在部署 application-ingress.yaml 文件定义的路径后，正如我们预期的那样在 AWS 控制台中创建了定义的路径，并且目标组也很健康。

但它只能工作/*，其余路径(/app1、/app2)无法工作并出现错误 404。请找到下面的 ingress yaml 文件。

Let's say when I'm trying to access /app1 page https://my-domain-name/app1 getting error HTTP ERROR 404

Same way /app2 page https://my-domain-name/app2 getting error HTTP ERROR 404

And last one is /app3 page https://my-domain-name/app3 page is working as we expected
