# Deploying multi Haproxy Ingress Controllers
|
||
|
|
|
||
|
|
This example aims to demonstrate the Deployment of multi haproxy ingress controllers.
|
||
|
|
|
||
|
|
## Prerequisites
|
||
|
|
|
||
|
|
This ingress controller doesn't yet have support for
|
||
|
|
[ingress classes](/examples/PREREQUISITES.md#ingress-class). You MUST turn
|
||
|
|
down any existing ingress controllers before running HAProxy Ingress controller or
|
||
|
|
they will fight for Ingresses. This includes any cloudprovider controller.
|
||
|
|
|
||
|
|
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
|
||
|
|
```
|
||
|
|
|
||
|
|
## 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
|
||
|
|
```
