HAPROXY Ingress Test

This configuration can be used to set up a test cluster to verify use of the HAPROXY Ingress Controller for Rate Limiting.

Set Up

1. Create a test project with a Kubernetes cluster
2. Apply all of the yaml files
3. Use kubectl get services -A to get the external IP of the ingress-controller
4. Test using curl -v [ip]:80/echo ten times, confirming 200 response each time
5. Confirm 403 on the eleventh attempt

Configuration Details

1. The echo ingress is set up to limit rate on http-request
2. The echo ingress specifies haproxy in ingressClassName
3. The haproxy-ingress file contains an IngressClass that binds the ingressClassName to the ingress controller

Note that the haproxy-ingress file is mostly identical to the one in the installation documentation under "Install with kubectl".

Rate Limiting Details

For detail on the rate limiting, search for stick-table in the yaml files and refer to the Introduction to HAProxy Stick Tables.

The Ingress Controller 1.5 announcement gives additional detail on this functionality.
