Create an Azure OpenAI, LangChain, ChromaDB, and Chainlit chat app in AKS using Terraform

Hi Ajmal_Yazdani, this is really an interesting question! I checked the documentation at:

• https://learn.microsoft.com/en-us/azure/aks/app-routing?tabs=default%2Cdeploy-app-default
• https://learn.microsoft.com/en-us/azure/aks/app-routing-dns-ssl
• https://learn.microsoft.com/en-us/azure/aks/app-routing-nginx-prometheus
• https://learn.microsoft.com/en-us/azure/aks/app-routing-migration

and I could not find any reference to how to configure the application routing addon to deploy a manager NGINX ingress controller where the service is exposed via an internal load balancer. In this case, I suggest that you disable the installation of the managed NGINX ingress controller via the application routing addon by setting the http_application_routing_enabled Terraform variable to false. Then, modify the the nginx_ingress_controller.tf module under terraform/modules/kubernetes add the following parameter:

set {

    name  = "controller.service.annotations.service\\.beta\\.kubernetes\\.io/azure-load-balancer-internal"

    value = "true"

  }

I didn't test it, but this should configure the NGINX ingress controller installed via Helm chart to expose the service via an internal load balancer. Hope this helps.
