HAProxy is an open-source proxy application. For more information, see [HAProxy](https://www.haproxy.org).

If you are running HAProxy on a cluster with the Fargate launch type, you need to set up a Fargate profile before doing the steps in this procedure. To set up the profile, enter the following command. Replace *MyCluster* with the name of your cluster.

```
eksctl create fargateprofile --cluster MyCluster \
--namespace haproxy-ingress-sample --name haproxy-ingress-sample
```
