Using the AKS http-addon returns a 503 for my service

问题

I have a service that I want to expose publicly over http running on AKS. I created a Kubernetes cluster and enabled the HTTP addon following these instructions here. I then launched a service myservicea in namespace mynamespace. And then I created an ingress controller for using the following configuration.

---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: myservicea-ingress
  namespace: mynamespace
  annotations:
    kubernetes.io/ingress.class: addon-http-application-routing
spec:
  rules:
  - host: myservicea.XXXXXXX.westus.aksapp.io
    http:
      paths:
      - backend:
          serviceName: myservicea
          servicePort: 80
        path: /

The domain myservicea.XXXXXXX.westus.aksapp.io is reachable after several minutes, however, I only get an HTTP 503 error. So the ingress controller does not seem to be able to find my service. What could be the issue?

Well, if you create the service in a specific namespace. Then maybe you can set the deployment and ingress also in that specific namespace. And you should check in the portal if the host route the request to right namespace. I did the test follow the link you posted with just changing the namespace and it works in my side.

Hope this will be helpful. If you need more help please give me the message.
