# Container Insights with HAProxy

This example shows how to use aws-otel-collector to collect Prometheus metrics of HAProxy on EKS, and export them to
CloudWatch.

## Prerequisites

1. [Set Up EKS Cluster](setup-eks.md).

## Install HAProxy

1. Add Helm Repository.

```bash
helm repo add haproxy-ingress https://haproxy-ingress.github.io/charts
helm repo update
```

2. Install via Helm

```bash
# Create namespace to run HAProxy 
kubectl create namespace haproxy-ingress-sample

# Install HAProxy with prometheus annotation
helm install haproxy haproxy-ingress/haproxy-ingress \
--namespace haproxy-ingress-sample \
--set defaultBackend.enabled=true \
--set controller.stats.enabled=true \
--set controller.metrics.enabled=true \
--set-string controller.metrics.service.annotations."prometheus\.io/port"="9101" \
--set-string controller.metrics.service.annotations."prometheus\.io/scrape"="true"
```
