Install on Google GKE

This section shows you how to install HAProxy Kubernetes Ingress Controller in Google Kubernetes Engine. You can install either with Helm or kubectl.

Pre-installation checklist Jump to heading #

• A running GKE Kubernetes cluster
• The Google Cloud SDK
• The helm command-line tool
• The kubectl command-line tool

Connect to your GKE cluster Jump to heading #

1. Connect to your cluster using the gcloud command-line tool:

   nix
   gcloud init
   gcloud container clusters get-credentials [Your cluster name] --zone [Your zone] --project [Your project name]

   nix
   gcloud init
   gcloud container clusters get-credentials [Your cluster name] --zone [Your zone] --project [Your project 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.

Install Jump to heading #

Choose one of the following installation methods:

Install with Helm Jump to heading #

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

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

   This will create a Google Cloud 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 a Google Cloud 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

nix
kubectl get services --namespace haproxy-controller
