Hi!

I'm stuck at step 10 from Lab 11.2.

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

  1. apiVersion: networking.k8s.io/v1
  2. kind: Ingress
  3. metadata:
  4.   name: ingress-test
  5.   namespace: default
  6. spec:
  7.   rules:
  8.   - host: www.external.com
  9.     http:
  10.       paths:
  11.       - backend:
  12.           service:
  13.             name: web-one
  14.             port:
  15.               number: 80
  16.         path: /
  17.         pathType: ImplementationSpecific
  18. status:
  19.   loadBalancer: {}

Applied it successfully:

  1. [14:02]user@ubuntu-vbox-k8s-master[ingress-nginx]$ kubectl get ingress
  2. NAME           CLASS    HOSTS              ADDRESS   PORTS   AGE
  3. ingress-test   <none>   www.external.com             80      11m

And got working web-one service and other:

  1. [14:02]user@ubuntu-vbox-k8s-master[ingress-nginx]$ kubectl get svc
  2. NAME                                           TYPE           CLUSTER-IP      EXTERNAL-IP   PORT(S)                      AGE
  3. kubernetes                                     ClusterIP      10.96.0.1       <none>        443/TCP                      30d
  4. myingress-ingress-nginx-controller             LoadBalancer   10.100.135.99   <pending>     80:31209/TCP,443:31337/TCP   13m
  5. myingress-ingress-nginx-controller-admission   ClusterIP      10.105.23.218   <none>        443/TCP                      13m
  6. web-one                                        ClusterIP      10.103.23.224   <none>        80/TCP                       7h26m
  7. web-two                                        ClusterIP      10.108.186.93   <none>        80/TCP

Then I tried Curl:

  1. [14:03]user@ubuntu-vbox-k8s-master[ingress-nginx]$ curl 10.100.135.99
  2. <html>
  3. <head><title>404 Not Found</title></head>
  4. <body>
  5. <center><h1>404 Not Found</h1></center>
  6. <hr><center>nginx</center>
  7. </body>
  8. </html>

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

  1. [14:04]user@ubuntu-vbox-k8s-master[ingress-nginx]$ curl -H "Host: www.external.com" http://10.100.135.99
  2. <html>
  3. <head><title>404 Not Found</title></head>
  4. <body>
  5. <center><h1>404 Not Found</h1></center>
  6. <hr><center>nginx</center>
  7. </body>
  8. </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:

    1. ...
    2. metadata:
    3.   annotations:
    4.     kubernetes.io/ingress.class: nginx
    5.   name: ingress-test
    6. ...

    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
