Configure Ingress to accomodate nested services on the same domain

August 14, 2023

Configure cluster for web application with frontend and backend on one domain:

frontend on /,
backend on /backend.

Using such configuration ensures Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/html" won't appear since we rewrite all requests correctly.

This problem is discussed in Ticket Ingress changes original content type #5265 ¹.

Peak into configuration as follows

ingress-config.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: application-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: /$1
spec:
  rules:
  - host: test.application.com
    http:
      paths:
      - path: /?(.*)
        pathType: Prefix
        backend:
          service:
            name: application-frontend-service
            port:
              number: 80   
      - path: /backend/?(.*)
        pathType: Prefix
        backend:
          service:
            name: application-backend-service
            port:
              number: 80
