Ingress not forwarding traffic to pod - nginx

Question

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.

Answer 1

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

Answer 2

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