Ingress returning 404 even though Pods are healthy? 🤔 This is a classic Kubernetes interview + production trap. A user hits: 👉 http://example.com/app ✔ Service is running ✔ Pods are healthy ❌ Still getting 404 Not Found So what’s actually wrong? The request never matches the Ingress rule. In this case, the Ingress was configured with: path: /application pathType: Exact But the client requested /app. Because Exact paths must match character-by-character, Kubernetes correctly returns 404 — even though everything behind it is fine. ✅ The fix Use the correct path and a safer match type: path: /app pathType: Prefix Now any request starting with /app is routed correctly to the backend. 💡 Key takeaway (important for interviews): If you see 404 at the Ingress level, don’t touch the app first. Always verify path + pathType — most issues live there. 📌 Real-world Kubernetes troubleshooting like this is covered in my Kubernetes Zero to Interview-Hero series. 📺 Free on YouTube — TechWorld With Sahana #Kubernetes #Ingress #DevOps
