CKA Gateway API Lab – HTTPRoute Not Routing Without sectionName in parentRefs

Kubernetes
#1

Hi KodeKloud Team,

I encountered an issue while working through the “Practice Test – Gateway API” lab. In Task 8, we are instructed to expose the frontend-svc using an HTTPRoute resource named frontend-route.

While the solution creates the HTTPRoute correctly, the application consistently returned a 404 Not Found when accessed via the NodePort (curl http://<NodeIP>:30080/). After some investigation, I realized the issue was due to a missing sectionName in the parentRefs field of the HTTPRoute.

To resolve the issue, I added the following line to the parentRefs section in http-route.yaml:

parentRefs:

  • name: nginx-gateway
    namespace: nginx-gateway
    sectionName: http # this line was missing
    Once I added this, the route was correctly attached to the Gateway listener and the service was accessible.

It seems the provided solution in the lab might be missing this required field, which is needed to attach the route to the correct listener when using the Gateway API.

Hope this helps improve the experience for other learners.

Thanks for the great content and hands-on labs!

Hi @Raphael-Taguemkam
Thanks for highlighting.
Yes, we also need to set the sectionName to Gateways listeners.name.

I’ll update the lab team about this.
