Kong Ingress on Azure Kubernetes Service (AKS)

Requirements

1. A fully functional AKS cluster. Please follow Azure’s Guide to setup an AKS cluster.
2. Basic understanding of Kubernetes
3. A working kubectl linked to the AKS Kubernetes cluster we will work on. The above AKS setup guide will help you set this up.

Deploy the Kong Ingress Controller

You can deploy the Kong Ingress Controller using kubectl or Helm:

$ kubectl create -f https://raw.githubusercontent.com/Kong/kubernetes-ingress-controller/v2.6.0/deploy/single/all-in-one-dbless.yaml

helm repo add kong https://charts.konghq.com
helm repo update
helm install kong kong/ingress -n kong --create-namespace

The results should look like this:

   namespace/kong created
   customresourcedefinition.apiextensions.k8s.io/kongplugins.configuration.konghq.com created
   customresourcedefinition.apiextensions.k8s.io/kongconsumers.configuration.konghq.com created
   customresourcedefinition.apiextensions.k8s.io/kongcredentials.configuration.konghq.com created
   customresourcedefinition.apiextensions.k8s.io/kongingresses.configuration.konghq.com created
   serviceaccount/kong-serviceaccount created
   clusterrole.rbac.authorization.k8s.io/kong-ingress-clusterrole created
   clusterrolebinding.rbac.authorization.k8s.io/kong-ingress-clusterrole-nisa-binding created
   service/kong-proxy created
   service/kong-validation-webhook created
   deployment.apps/ingress-kong created
   deployment.apps/proxy-kong created
   ingressclass.networking.k8s.io/kong created

NAME: kong
LAST DEPLOYED: Tue Oct  3 15:12:38 2023
NAMESPACE: kong
STATUS: deployed
REVISION: 1
TEST SUITE: None

Note: this process could take up to five minutes the first time.

Setup environment variables

Next, we will setup an environment variable with the IP address at which Kong is accessible. This will be used to actually send requests into the Kubernetes cluster.

Execute the following command to get the IP address at which Kong is accessible:

$ kubectl get services -n kong
NAME         TYPE           CLUSTER-IP      EXTERNAL-IP     PORT(S)                      AGE
kong-proxy   LoadBalancer   10.63.250.199   203.0.113.42   80:31929/TCP,443:31408/TCP   57d

Let’s setup an environment variable to hold the IP address:

$ export PROXY_IP=$(kubectl get -o jsonpath="{.status.loadBalancer.ingress[0].ip}" service -n kong kong-proxy)

Note: It may take a while for Microsoft Azure to actually associate the IP address to the kong-proxy Service.

Once you’ve installed the Kong Ingress Controller, please follow our getting started tutorial to learn about how to use the Ingress Controller.
