Install Nginx Ingress Controller to AKS

Page content

In this pos I will show you how you can install Nginx Ingress Controlle to AKS (Azure Kubernetes Service) Cluster.

Parts of the AKS series

Get AKS credentials

az login
az aks get-credentials --resource-group test-cluster --name test-cluster
kubectl get nodes

Create ingress with static public ip

az network public-ip create \
--location <REGION_NAME> \
--resource-group <RESOURCE_GROUP_NAME> \
--name <IP_NAME> --sku Standard \
--allocation-method static \
--query publicIp.ipAddress -o tsv

# 51.105.230.165

Deploy nginx ingress controller with helm

kubectl create namespace ingress

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx

helm install <INGERSS_NAME> \
ingress-nginx/ingress-nginx \
--namespace ingress \
--set controller.replicaCount=2 \
--set controller.nodeSelector."kubernetes\.io/os"=linux \
--set controller.admissionWebhooks.patch.nodeSelector."kubernetes\.io/os"=linux \
--set defaultBackend.nodeSelector."kubernetes\.io/os"=linux \
--set controller.service.annotations."service\.beta\.kubernetes\.io/azure-load-balancer-health-probe-request-path"=/healthz \
--set controller.service.loadBalancerIP="51.105.230.165"

kubectl --namespace ingress get services -o wide -w nginx-ingress-controller
kubectl get service -l app=nginx-ingress --namespace ingress

Create an ingress controller to an internal virtual network in

By default, an NGINX ingress controller is created with a dynamic public IP address assignment. A common configuration requirement is to use an internal, private network and IP address. This approach allows you to restrict access to your services to internal users, with no external access. This example assigns 10.240.0.42 to the loadBalancerIP resource.

helm install nginx-ingress \
ingress-nginx/ingress-nginx \
--namespace ingress \
--set controller.ingressClass=internal \
--set controller.replicaCount=2 \
--set controller.nodeSelector."kubernetes\.io/os"=linux \
--set controller.admissionWebhooks.patch.nodeSelector."kubernetes\.io/os"=linux \
--set defaultBackend.nodeSelector."kubernetes\.io/os"=linux \
--set controller.service.annotations."service\.beta\.kubernetes\.io/azure-load-balancer-internal"=true \
--set controller.service.annotations."service\.beta\.kubernetes\.io/azure-load-balancer-health-probe-request-path"=/healthz \
--set controller.service.loadBalancerIP=10.224.0.42

Create an ingress route

apiVersion: networking.k8s.io/v1beta1
kind: Ingress
metadata:
  name: hello-world-ingress
  namespace: ingress-basic
  annotations:
    kubernetes.io/ingress.class: internal
