How to run kong gateway and kong ingress controller in the same cluster

[davidshare]

I am trying to set up kong gateway and the ingress controller in an EKS cluster. Both the controller, and the gateway create classic LBs in the cluster.

The problem is that the ingress resources are destroyed and recreated continuously. It will create the resource and point it to the LB of the gateway, then destroy it and create the ingress resource pointing to the controller LB.

I am new to trying to use kong. Please why does the gateway need an LB if the ingress controller has an LB, or how do I disable the gateway LB so that they all use the ingress controller.

I have tried going through docs, but I am not getting any clarity.

Also, how do I set the LB to be NLB instead of CLB?
