Ingress not forwarding traffic to pod-CodePudding

Ingress is not forwarding traffic to pods. Application is deployed on Azure Internal network. I can access app successfully using pod Ip and port but when trying Ingress IP/ Host I am getting 404 not found. I do not see any error in Ingress logs. Bellow are my config files. Please help me if I am missing anything or a how I can troubleshoot to find issue.

CodePudding user response：

You have mentioned the wrong service name under the ingress definition. Service name should be aks-helloworld-one as per the service definition.

CodePudding user response：

Correct your service name and service port in ingress.yaml.

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

Actually, you can use below command to confirm if ingress has any endpoint.

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