Add integration with Application Gateway for Containers for HTTP ingress

[tedvanderveen]

Proposal

Integrate KEDA-HTTP with Azure Application Gateway for containers. AGC aligns with the k8s Gateway API 1.0.0 spec (released a couple of months ago) and provides loadbalancer/firewall ingress (L7 loadbalancer) for AKS.

Use-Case

Having one integrated solution for handling incoming HTTP traffic for AKS and handle scaling (to zero) of web apps on AKS.

Is this a feature you are interested in implementing yourself?

No

Anything else?

No response

Mind elaborating on how you see this in action? Are you asking to make it part of AGC?

@tomkerkhove I'm sorry for not getting back to you sooner. What I was referring to, is to use AGC telemetry data to scale HTTP workloads in the cluster. When reading this section of the project main Readme, I was thinking that AGC could be well equiped to supply needed metrics data about ingress HTTP events.

Azure Application Gateway for Containers is an Azure specific implementation of the Kubernetes Gateway API 1.0 spec released some 9 months ago: https://gateway-api.sigs.k8s.io and many cloud providers have already implemented the api: https://gateway-api.sigs.k8s.io/implementations.

As k8s gateways sit in front of the cluster like an L7 router/load balancer, it could supply KADA with data/metrics for auto scaling?

@tomkerkhove I now noticed how you raised the same subject here
