Is there an existing issue for this?

Does this enhancement require public documentation?

I am using the kic-gateway-api for http routing. Now I need the support for websocket routing using kic-gateway-api in v3.2.

I saw that was something that implements but i could not achieve on my configuration files (https://github.com/Kong/kubernetes-ingress-controller/blob/02cb9499ed6c828bd811e6dc65c60839926c4e4f/CHANGELOG.md?plain=1#L540).

First of all, supporting WebSockets is an Enterprise feature. Could you let me know if you're using an Enterprise Kong Gateway with a valid license? Otherwise, it won't work.

Also please provide a minimal reproducible example of a configuration that doesn't work for you

Hi @programmer04 ,

Thanks for your answer!

  1. I am not using the Enterprise License. It is not clear in the Documentation (https://docs.konghq.com/kubernetes-ingress-controller/3.2.x/) the limits of Community Edition. I understood is the same containers, but providing the License key the Enterprise things are allowed, is that right?

  2. Please let me know if the Ingress, not the Gateway API allows to use WebSockets or I will have to provide another Ingress Controller like Istio Ingress, Nginx or which one you better indicates for OpenSource solution?

  3. The configuration presented on this topic is allowed outside the Enterprise Edition? https://github.com/Kong/kubernetes-ingress-controller/issues/995

Since I am a University Researcher and I am deploying an On-Premises with few access just to take the Technology under Proof and establishes a new concept of scalable applications, the Enterprise will have a cost that I could not justfies.

Please can you heklp me answring these questions 1, 2 and 3?

Many Thanks!
