Kubernetes - Ingress

You see 404 errors when accessing your service through Nginx Ingress. The Ingress YAML is:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: nginx-ingress
  annotations:
    kubernetes.io/ingress.class: "nginx"
spec:
  rules:
  - host: example.com
    http:
      paths:
      - path: /app
        pathType: Prefix
        backend:
          service:
            name: app-service
            port:
              number: 80

What is a likely cause?

AThe host 'example.com' is misspelled

BThe client is requesting '/' instead of '/app' path

CThe annotation is incorrect for Nginx

DThe service port 80 is closed

Step-by-Step Solution

Solution:

Step 1: Analyze path in Ingress
The Ingress routes only requests starting with '/app'. Requests to '/' won't match.
Step 2: Understand 404 cause
Requests to '/' get no matching rule, causing 404 errors.
Final Answer:
The client is requesting '/' instead of '/app' path -> Option B
Quick Check:
Path mismatch causes 404 errors [OK]

Quick Trick: Match client request path with Ingress path [OK]

Common Mistakes:

Blaming service port without checking path
Assuming annotation is wrong
Ignoring host correctness
