我一直在尝试在亚马逊 EKS 上设置 istio，一切正常，负载均衡器等已分配，但在重新部署服务后，我在 Cloudfront 上得到 502。

我真的不知道发生了什么，并且 istio 分析显示一切都在验证中

istioctl analyze --all-namespaces

✔ No validation issues found when analyzing all namespaces.

我只是想学习，我已经使用 bookinfo 作为示例完成了他们的教程

编辑 1：当我尝试访问负载均衡器主机名时，它会引发 404 错误

这是我的配置文件：

网关.yaml：

apiVersion: networking.istio.io/v1alpha3
kind: Gateway
metadata:
  name: demo-gateway
spec:
  selector:
    istio: ingressgateway
  servers:
  - port:
      number: 80
      name: http
      protocol: HTTP
    hosts:
    - "mydomain.com"
    tls:
      httpsRedirect: true # sends 301 redirect for http requests
  - port:
      number: 443
      name: https-443
      protocol: HTTP
    hosts:
    - "mydomain.com"

apiVersion: networking.istio.io/v1alpha3

  hosts:

  gateways:
  - demo-gateway
  http:
  - match:
    - uri:
        prefix: /
    route:
    - destination:
        host: servicename
        port:
          number: 8080

部署.yaml：
