Installation

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 Jump to heading

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

Connect to your AKS cluster Jump to heading

  1. Connect to your cluster using the Azure CLI:

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

    nix
    kubectl get pods
    nix
    kubectl get pods

    If your cluster is new it may not have any resources:

    No resources found in default namespace.

Choose one of the following installation methods:

Install with Helm Jump to heading

Helm values file

The following example uses --set invocations to configure the ingress controller. When installing with Helm, you can instead use a Helm values file to provide your configuration values. Using a Helm values file can provide for better traceability of configuration changes and reduce the complexity of Helm installation commands.

  1. Add the HAProxy Technologies Helm repository:

    nix
    helm repo add haproxytech https://haproxytech.github.io/helm-charts
    nix
    helm repo add haproxytech https://haproxytech.github.io/helm-charts
  2. Update your list of Helm charts:

    nix
    helm repo update
    nix
    helm repo update
  3. Install the latest version of the ingress controller with type set to LoadBalancer:

    nix
    helm install haproxy-kubernetes-ingress haproxytech/kubernetes-ingress \
    --create-namespace \
    --namespace haproxy-controller \
    --set controller.service.type=LoadBalancer \
    --set controller.service.annotations."service\.beta\.kubernetes\.io/azure-load-balancer-health-probe-request-path"="/healthz"
    nix
    helm install haproxy-kubernetes-ingress haproxytech/kubernetes-ingress \
    --create-namespace \
    --namespace haproxy-controller \
    --set controller.service.type=LoadBalancer \
    --set controller.service.annotations."service\.beta\.kubernetes\.io/azure-load-balancer-health-probe-request-path"="/healthz"

    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.

    About ingress class

    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 ingressClassName: haproxy. You can disable this by setting --set controller.ingressClass=null when calling helm install.

    This change was introduced in version 1.6.

Install with kubectl Jump to heading

  1. Download the latest source code from the HAProxy Kubernetes Ingress Controller GitHub page.

  2. Edit the file deploy/haproxy-ingress.yaml.

  3. Change the Service resource in haproxy-ingress.yaml, setting its type field to LoadBalancer, which is the preferred mode when running in the cloud:

    haproxy-ingress.yaml
    yaml
    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
    haproxy-ingress.yaml
    yaml
    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
  4. Use the kubectl apply command to deploy the controller:

    nix
    kubectl apply -f haproxy-ingress.yaml
    nix
    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 Jump to heading

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

nix
kubectl get pods --namespace haproxy-controller
nix
kubectl get pods --namespace haproxy-controller
output
text
NAME READY STATUS RESTARTS AGE
haproxy-kubernetes-ingress-7dd4cc4b-x5fkv 1/1 Running 0 1m
output
text
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:

nix
kubectl get services --namespace haproxy-controller
nix
kubectl get services --namespace haproxy-controller
output
text
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
output
text
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
