入口不将流量转发到 pod

Question

Ingress 没有将流量转发到 pods。应用程序部署在 Azure 内部网络上。我可以使用 pod Ip 和端口成功访问应用程序，但是在尝试 Ingress IP/Host 时我收到 404 not found。我在 Ingress 日志中没有看到任何错误。下面是我的配置文件。如果我遗漏了什么或如何解决问题，请帮助我。

Answer 1

您在入口定义下提到了错误的服务名称。根据服务定义，服务名称应为 aks-helloworld-one。

Answer 2

更正您在 ingress.yaml 中的服务名称和服务端口。

spec:
  ingressClassName: nginx
  rules:
  - http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            # wrong: name: aks-helloworld
            name: aks-helloworld-one  
            port:
              # wrong: number: 80
              number: 8080

实际上，您可以使用以下命令来确认入口是否有任何端点。

kubectl describe ingress hello-world-ingress -n ingress-basic

入口不将流量转发到 pod

Ingress not forwarding traffic to pod

nginx

kubernetes

kubernetes-ingress
