My app is running on Windows Containers using AKS. Now we are trying to migrate our Static Assets to Azure Blob/Azure CDN and serve assets from there instead of our App. Following various articles, I setup the below way with no success.

apiVersion: v1
kind: Service
metadata:
  name: app-fe
  namespace: fe-ns
  labels:
    app.kubernetes.io/name:app-fe
    helm.sh/chart: os-20210118.1
    app.kubernetes.io/instance: prod
    app.kubernetes.io/managed-by: Helm
spec:
  type: ExternalName
  externalName: fe-assets.azureedge.net

Ingress file

annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: /
    nginx.ingress.kubernetes.io/force-ssl-redirect: "true"
spec:
  rules:
    - host: "domain.com"
      http:
        paths:
          - path: /
            backend:
              serviceName: app-fe
              servicePort: 80/443 (tried with both)

Any leads on this is appreciated. Thanks
