Lab 11.2 Why Ingress rule is not working?

Hi!

I'm stuck at step 10 from Lab 11.2.

I've used ingress.yaml config from labs solutions folder:

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: ingress-test
  namespace: default
spec:
  rules:
  - host: www.external.com
    http:
      paths:
      - backend:
          service:
            name: web-one
            port:
              number: 80
        path: /
        pathType: ImplementationSpecific
status:
  loadBalancer: {}

Applied it successfully:

[14:02][email protected][ingress-nginx]$ kubectl get ingress
NAME           CLASS    HOSTS              ADDRESS   PORTS   AGE
ingress-test   <none>   www.external.com             80      11m

And got working web-one service and other:

[14:02][email protected][ingress-nginx]$ kubectl get svc
NAME                                           TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)                      AGE
kubernetes                                     ClusterIP      10.96.0.1       <none>        443/TCP                      30d
myingress-ingress-nginx-controller             LoadBalancer   10.100.135.99   <pending>     80:31209/TCP,443:31337/TCP   13m
myingress-ingress-nginx-controller-admission   ClusterIP      10.105.23.218   <none>        443/TCP                      13m
web-one                                        ClusterIP      10.103.23.224   <none>        80/TCP                       7h26m
web-two                                        ClusterIP      10.108.186.93   <none>        80/TCP

Then I tried Curl:

[14:03][email protected][ingress-nginx]$ curl 10.100.135.99
<html>
<head><title>404 Not Found</title></head>
<body>
<center><h1>404 Not Found</h1></center>
<hr><center>nginx</center>
</body>
</html>

It was expected, but I've got same for request with header:

[14:04][email protected][ingress-nginx]$ curl -H "Host: www.external.com" http://10.100.135.99
<html>
<head><title>404 Not Found</title></head>
<body>
<center><h1>404 Not Found</h1></center>
<hr><center>nginx</center>
</body>
</html>

Could anybody help?
Thanks in advance,

    Hi @Gim6626,

    As mentioned in an earlier solution, due to recent changes in the Ingress and Controller relationship, an annotation is required on the Ingress resource:

    ...
    metadata:
      annotations:
        kubernetes.io/ingress.class: nginx
      name: ingress-test
    ...
    

    Regards,
    -Chris

    Step 15 does not work too, but in other way - it just shows fixed nginx page does not matter what header is passed
