Install on Azure AKS

This guide shows you how to install HAProxy Kubernetes Ingress Controller in Azure Kubernetes Service. You can install either with Helm or kubectl.

Pre-installation checklist

• A running AKS Kubernetes cluster
• The Azure CLI
• The helm command-line tool
• The kubectl command-line tool

Connect to your AKS cluster

1. Connect to your cluster using the Azure CLI:

   $ az account set --subscription [Your Azure subscription ID]
   $ az aks get-credentials --resource-group [Your resource group] --name [Your AKS cluster name]

2. Check that you can access the cluster by calling kubectl get pods:

   $ kubectl get pods

   output

   No resources found in default namespace.
   

Install

Choose one of the following installation methods:

Install with Helm

1. Add the HAProxy Technologies Helm repository:

   $ helm repo add haproxytech https://haproxytech.github.io/helm-charts

2. Update your list of charts:

   $ helm repo update

3. Install the latest version of the ingress controller with type set to LoadBalancer:

   $ helm install haproxy-kubernetes-ingress haproxytech/kubernetes-ingress \
       --create-namespace \
       --namespace haproxy-controller \
       --set controller.service.type=LoadBalancer

   This will create an Azure Load Balancer that routes traffic to the ingress controller service. You can map the load balancer’s IP address to your public DNS domain name.

   By default, the Helm chart adds --ingress.class=haproxy to the ingress controller. That means that it will use Ingress resources only if they specify an annotation of kubernetes.io/ingress.class: haproxy. You can disable this by setting --set controller.ingressClass=null when calling helm install.

Install with kubectl

1. Download the deployment YAML file

2. Edit the haproxy-ingress Service object in the YAML file, setting its type field to LoadBalancer:

   apiVersion: v1
   kind: Service
   metadata:
     labels:
       run: haproxy-ingress
     name: haproxy-ingress
     namespace: haproxy-controller
   spec:
     selector:
       run: haproxy-ingress
     type: LoadBalancer
     ports:
     - name: http
       port: 80
       protocol: TCP
       targetPort: 80
     - name: https
       port: 443
       protocol: TCP
       targetPort: 443
     - name: stat
       port: 1024
       protocol: TCP
       targetPort: 1024

3. Use the kubectl apply command to deploy the controller:

   $ kubectl apply -f haproxy-ingress.yaml

   This will create an Azure Load Balancer that routes traffic to the ingress controller service. You can map the load balancer’s IP address to your public DNS domain name.

Check your installation

Verify that the controller is installed into your Kubernetes cluster by using the command kubectl get pods:

$ kubectl get pods --namespace haproxy-controller

output

NAME                                        READY   STATUS    RESTARTS   AGE
haproxy-kubernetes-ingress-7dd4cc4b-x5fkv   1/1     Running   0          1m

Get the External IP, which you can use to access your cluster:

$ kubectl get services --namespace haproxy-controller

output

NAME                         TYPE           CLUSTER-IP   EXTERNAL-IP     PORT(S)                                     AGE
haproxy-kubernetes-ingress   LoadBalancer   10.0.40.8    20.62.154.138   80:31669/TCP,443:30449/TCP,1024:31713/TCP   2m43s
