-# Deploying multi Haproxy Ingress Controllers
-
-This example aims to demonstrate the Deployment of multi haproxy ingress controllers.
-
-## Prerequisites
-
-If you have another Ingress controller deployed, you will need to make sure your
-Ingress resources target exactly one Ingress controller by specifying the
-[ingress.class](/examples/PREREQUISITES.md#ingress-class) annotation as
-`haproxy`.
-
-This document has also the following prerequisites:
-
-* Create a [TLS secret](/examples/PREREQUISITES.md#tls-certificates) named `tls-secret` to be used as default TLS certificate
-
-Creating the TLS secret:
-
-```console
-$ openssl req \
-  -x509 -newkey rsa:2048 -nodes -days 365 \
-  -keyout tls.key -out tls.crt -subj '/CN=localhost'
-$ kubectl create secret tls tls-secret --cert=tls.crt --key=tls.key
-$ rm -v tls.crt tls.key
-```
-
-## Default Backend
-
-The default backend is a service of handling all url paths and hosts the haproxy controller doesn't understand. Deploy the default-http-backend as follow:
-
-```console
-$ kubectl create -f default-backend.yaml 
-deployment "default-http-backend" created
-service "default-http-backend" created
-
-$ kubectl get svc
-NAME                   CLUSTER-IP    EXTERNAL-IP   PORT(S)   AGE
-default-http-backend   192.168.3.4   <none>        80/TCP    30m
-
-$ kubectl get pods
-NAME                                    READY     STATUS    RESTARTS   AGE
-default-http-backend-q5sb6              1/1       Running   0          30m
-```
-
-## RBAC Authorization
-
-Check the [RBAC sample](/examples/rbac/haproxy) if deploying on a cluster with
-[RBAC authorization](https://kubernetes.io/docs/admin/authorization/rbac/).
-
-## Ingress Deployment
-
-Deploy the Deployment of multi controllers as follows:
-
-```console
-$ kubectl apply -f haproxy-ingress-deployment.yaml
-deployment "haproxy-ingress" created
-```
-
-Check if the controller was successfully deployed:
-```console
-$ kubectl get deployment
-NAME                   DESIRED   CURRENT   UP-TO-DATE     AVAILABLE   AGE
-default-http-backend   1         1         1              1           30m
-haproxy-ingress        2         2         2              2           45s
-
-$ kubectl get pods
-NAME                                    READY     STATUS    RESTARTS   AGE
-default-http-backend-q5sb6              1/1       Running   0          35m
-haproxy-ingress-1779899633-k045t        1/1       Running   0          1m
-haproxy-ingress-1779899633-mhthv        1/1       Running   0          1m
