Kong Ingress on Azure Kubernetes Service (AKS)

Requirements

A fully functional AKS cluster. Please follow Azure’s Guide to setup an AKS cluster.
Basic understanding of Kubernetes
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
    

      Helm Charts
    
$ kubectl create -f https://raw.githubusercontent.com/Kong/kubernetes-ingress-controller/v2.8.2/deploy/single/all-in-one-dbless.yaml
helm repo add kong https://charts.konghq.com
helm repo update
helm install kongdocs kong/kong

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
configmap/kong-server-blocks created
service/kong-proxy created
service/kong-validation-webhook created
deployment.extensions/kong created

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.
