HAProxy Kubernetes Ingress Controller Documentation 1.4

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

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

Connect to your GKE cluster

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

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

Check that you can access the cluster by calling kubectl get pods:
```
$ kubectl get pods
```

Install

Choose one of the following installation methods:

Install with Helm

Add the HAProxy Technologies Helm repository:

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

Update your list of charts:
```
$ helm repo update
```
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 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.

Install with kubectl

Download the deployment YAML file

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

Use the kubectl apply command to deploy the controller:
```
$ 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

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

$ kubectl get pods --namespace haproxy-controller

  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

  NAME                         TYPE           CLUSTER-IP   EXTERNAL-IP   PORT(S)                                     AGE
  haproxy-kubernetes-ingress   LoadBalancer   10.8.14.69   34.68.15.92   80:32693/TCP,443:30866/TCP,1024:32181/TCP   45s
