Overview

Existing AKS Documentation

There are 3 options listed here: https://docs.microsoft.com/en-us/azure/api-management/api-management-kubernetes

• APIM + Public AKS Service, no shared Vnet
• APIM + Public AKS Ingress, no shared Vnet
• APIM + Private AKS in same Vnet, no ingress

A missing scenario is:

• APIM + Private AKS in same Subnet, with ingress

This example is designed to walk through this example

Install this example

To use this example, perform the following:

Create ingress similiar to template below

• The /$2 is important to remove the APIM URL suffix as it comes through since your app is likely not expecting it.

Create an ingress controller with an internal LB:

helm install nginx-ingress stable/nginx-ingress \
    --namespace ingress-basic \
    -f internal-ingress.yaml \
    --set controller.replicaCount=2 \
    --set controller.nodeSelector."beta\.kubernetes\.io/os"=linux \
    --set defaultBackend.nodeSelector."beta\.kubernetes\.io/os"=linux

Create the kuard and podinfo deployment, service and ingress rules

kubectl apply -f podinfo.yaml

Create the APIM instance and create the API’s pointing to the AKS Ingress

1. Create APIM instance
2. Create Blank API for podinfo
   • API URL suffix:
     • e.g. podinfo
   • Web service: http:///
     • e.g. http://10.240.0.42/podinfo
   • Disable “Subscription Required”
3. Create an Operation for the API
   • URL: /*

Verify APIM works

$ curl https://tmfflux.azure-api.net/podinfo
