+# Projet demo
+
+## Prerequis
+
+* k3d
+* kubectl
+* helm
+* helm-diff
+* helmfile
+
+## Créer le cluster
+
+    k3d cluster create -c k3d/k3d-cluster.yaml
+
+## Installer les charts helm (avec helmfile)
+
+    helmfile apply 
+
+## Intaller les différents services (avec kustomize)
+
+### Option 1 : configuration basée sur Ingress (standard kubernetes)
+
+    kubectl delete -f kubernetes/ingress-route/
+    kubectl apply -f kubernetes/ingress/
+
+### Option 2 : configuration basée sur IngressRoute (traefik)
+
+    kubectl delete -f kubernetes/ingress/
+    kubectl apply -f kubernetes/ingress-route/
+
+## Vérifier les objets
+
+### Option 1 : configuration basée sur Ingress (standard kubernetes)
+
+    k9s -n web -c ingress
+
+### Option 2 : configuration basée sur IngressRoute (traefik)
+
+    k9s -n web -c ingress-route
