Ajout du dépôt helm:
helm repo add haproxytech https://haproxytech.github.io/helm-charts
Mise à jour des métadonnées des dépôts helm :
helm repo update
Déploiement :
helm install kubernetes-ingress haproxytech/kubernetes-ingress
Vérification des pods haproxy controller :
kubectl get pods -A
Récupération du port d'écoute :
kubectl get svc
Ce qui doit ressembler à :
kubernetes-ingress NodePort 10.108.250.33 <none> 80:32650/TCP,443:31943/TCP,1024:32649/TCP 63m
Le port d'écoute ici est 32650 pour le HTTP, et 31943 pour le HTTPS.
Pour validation :
$ curl localhost:32650 default backend - 404
Pour acceder depuis l'exterieur, mieux vaut avoir une paire de haproxy (ou autres) devant le cluster k8s. Voici un exemple de configuration :

# to have these messages end up in /var/log/haproxy.log you will
# need to:
#
# 1) configure syslog to accept network log events. This is done
# by adding the '-r' option to the SYSLOGD_OPTIONS in
# /etc/sysconfig/syslog
#
# 2) configure local2 events to go to the /var/log/haproxy.log
# file. A line like the following can be added to
# /etc/sysconfig/syslog
#
# local2.* /var/log/haproxy.log
#
log 127.0.0.1 local2
