-
-- [Golang > 1.20](https://go.dev/)
-- [Docker](https://www.docker.com/)
-- [Git](https://git-scm.com/)

-
-1. Cloner le dépôt des sources du projet Bouncer

-
-2. Se positionner dans le répertoire du projet
-
-    ```

-
-3. Lancer le projet en mode "développement"
-
-    ```
-    make watch

+# Exemple de déploiement multi-noeuds avec Docker-Compose
+
+Le répertoire `misc/docker-compose` contient un exemple de déploiement de Bouncer multi-noeuds avec:
+
+- 3 instances du service `bouncer-proxy`;
+- 1 instance du service `haproxy` en frontal en charge du load-balancing;
+- 1 instance du service `bouncer-admin`;
+- 1 serveur Redis.
+
+## Prérequis
+
+- [Docker Compose](https://docs.docker.com/compose/)
+
+## Étapes
+
+1. Se positionner dans le répertoire puis lancer l'environnement avec la commande `docker-compose`:
+
+    ```bash
+    cd misc/docker-compose
+    docker-compose up
+    ```
+
+2. Entrer dans le conteneur `bouncer-admin` puis créer un jeton d'accès:
+
+    ```bash
+    docker-compose exec bouncer-admin /bin/sh
+    bouncer auth create-token --role writer > .bouncer-token
+    ```
+
+3. Créer un proxy via le CLI:
+
+    ```bash
+    bouncer admin proxy create --proxy-name myproxy --proxy-to "https://www.cadoles.com/"
+    bouncer admin proxy update --proxy-name myproxy --proxy-enabled=true
+    ```
+
+4. Via votre navigateur, accéder à l'URL http://127.0.0.1:8080. La page du site Cadoles devrait s'afficher. Dans le log de la commande `docker-compose up` vous devriez voir que les requêtes sont routées à tour de rôle sur les 3 instances de Bouncer en exécution.
