Hi,

I want to add a new SSL certificate to my Kubernetes cluster, and here’s how my routing works:

Suppose my main URL is abc.com and my ingress host URL is qwe.com.

So, when I hit abc.com, it routes like this: abc.com → Route 53 → API Gateway → Ingress Host (qwe.com) → Backend Service.

I get the response while seeing abc.com in the browser, with backend routing happening behind the scenes. Thus, my ingress URL remains hidden.

Current Ingress Configuration:

yaml

Copy code

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: dev-router-master
  annotations:
    nginx.ingress.kubernetes.io/proxy-body-size: "50m"
    nginx.ingress.kubernetes.io/enable-cors: "true"
    nginx.ingress.kubernetes.io/cors-allow-origin: "*"
    nginx.ingress.kubernetes.io/cors-allow-methods: "GET, POST, OPTIONS"
    nginx.ingress.kubernetes.io/cors-allow-headers: "DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range"
spec:
  ingressClassName: nginx
  rules:
    - host: qwe.com
      http:
        paths:
          - path: /api/dao
            pathType: Prefix
            backend:
              service:
                name: kyc-service
                port:
                  number: 80

Problem After Adding SSL:

After adding SSL to my NGINX ingress controller, whenever I hit abc.com, I am able to access the application, but it forwards the site from abc.com to qwe.com, and I see qwe.com in the browser.

Updated Ingress Configuration with SSL:

yaml

Copy code

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: dev-router-master
  annotations:
    nginx.ingress.kubernetes.io/proxy-body-size: "50m"
    nginx.ingress.kubernetes.io/enable-cors: "true"
    nginx.ingress.kubernetes.io/cors-allow-origin: "*"
    nginx.ingress.kubernetes.io/cors-allow-methods: "GET, POST, OPTIONS"
    nginx.ingress.kubernetes.io/cors-allow-headers: "DNT,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type,Range"
spec:
  ingressClassName: nginx
  tls:
    - hosts:
        - abc.com
        - qwe.com
      secretName: secret-key
  rules:
    - host: abc.com
      http:
        paths:
          - path: /api/dao
            pathType: Prefix
            backend:
              service:
                name: kyc-service
                port:
                  number: 80
    - host: qwe.com
      http:
        paths:
          - path: /api/dao
            pathType: Prefix
            backend:
              service:
                name: kyc-service
                port:
                  number: 80

Desired Result:

Whenever I hit abc.com, I should get a response on abc.com only, with all backend routing happening invisibly.

Cluster Information:

  • Kubernetes Version: AKS cluster with version 1.26.10
  • Ingress-NGINX Version:

yaml

Copy code

NGINX Ingress controller
Release: v1.3.0
Build: 2b7b74854d90ad9b4b96a5011b9e8b67d20bfb8f
Repository: https://github.com/kubernetes/ingress-nginx
NGINX Version: nginx/1.19.10

Can anyone help me achieve this without showing my ingress NGINX host URL?
