+
+## Authentification
+
+L'ensemble des appels aux APIs HTTP du service `bouncer-admin` sont authentifiées via l'utilisation d'un jeton [JWT](https://datatracker.ietf.org/doc/html/rfc7519) signé par la clé privée du serveur.
+
+Le jeton d'accès doit être transmis avec l'ensemble des appels aux points d'entrée via l'entête HTTP `Authorization` en respectant la forme suivante:
+
+```
+Authorization: Bearer <jwt>
+```
+
+### Génération d'un jeton d'authentification
+
+La génération d'un jeton d'authentification s'effectue via la commande suivante:
+
+```shell
+bouncer auth create-token --subject "<subject>" --role "<role>"
+```
+
+Où:
+
+- `"<subject>"` est une chaîne de caractère arbitraire ayant pour objectif d'identifier de manière unique l'utilisateur associé au jeton;
+- `"<role>"` peut prendre une des deux valeurs `reader` ou `writer` correspondant aux droits suivants respectifs:
+  - droit en lecture sur l'ensemble des entités (proxy, layer);
+  - droit en lecture ET en écriture sur l'ensemble des entités.

+- **Valeur par défaut:** `["*"]`
+- **Description:** Limiter l'action du layer à cette liste de patrons d'URLs. 
+
+    Par exemple, si vous souhaitez limiter votre restriction d'accès à l'ensemble d'une section "`/blog`" d'un site, vous pouvez déclarer la valeur `["*/blog*"]`. Les autres URLs du site ne seront pas affectées par la restriction.
+
+### `templateBlock`
+
+- **Type:** `string`

+# Métriques
+
+Bouncer expose un certain nombre de métriques Prometheus sur le serveur proxy ainsi que sur le serveur d'administration. Ces métriques sont par défaut accessibles sur `/.bouncer/metrics`. 
+
+Il est possible de configurer le point d'entrée de ces métriques ainsi que d'ajouter une authentification de type `Basic Auth` [via la configuration](../../../misc/packaging/common/config.yml) (voir les clés `admin.metrics` et `proxy.metrics`).
+
+Outre les métriques par défaut fournies par la librairie [Prometheus](https://prometheus.io/docs/guides/go-application/#instrumenting-a-go-application-for-prometheus), les serveurs Bouncer exposent également des métriques propres.
+
+Chaque layer associé à un proxy peut également ses propres métriques spécifiques. [Voir la page de documentation](./layers/README.md) de chaque layer pour plus d'informations.

+# Amorçage d'un serveur Bouncer via la configuration
+
+Il est possible d'amorcer des données par défaut (i.e. des "proxies" et "layers" associés) via la configuration du serveur d'administration.
+
+> **Attention** Ce mécanisme de modifiera pas des proxies déjà existants dans la base de données du serveur Bouncer. Autrement dit, si un proxy est déjà pré-existant lors du démarrage du serveur Bouncer, il ne sera pas modifié.
+
+La définition des proxies et layers par défaut s'effectue dans la section `bootstrap` du fichier de configuration. Deux possibilités pour définir les proxys à charger par défaut:
+
+- Utiliser un répertoire contenant des fichiers YAML (un par proxy) en définissant le chemin du répertoire via l'attribut `bootstrap.dir`;
+- Définir directement la liste des proxies via l'attribut `bootstrap.proxies`.

+# Créer son propre layer
+
+Dans ce tutoriel, nous verrons comment implémenter un layer personnalisé qui permettra d'ajouter une authentification de type [`Basic Auth](https://developer.mozilla.org/en-US/docs/Web/HTTP/Authentication) à un proxy.
+
+## Prérequis
+
+Avoir un environnement de développement local fonctionnel. Voir tutoriel ["Démarrer avec les sources"](./getting-started-with-sources.md).
+## Étapes
+### Préparer la structure de base du nouveau layer
+
+Une implémetation d'un layer se compose majoritairement de 3 éléments:
+
+- Une structure qui implémente une ou plusieurs interfaces (`director.MiddlewareLayer`, `director.RequestTransformerLayer` et/ou `director.ResponseTransformerLayer`);
+- Un schéma au format [JSON Schema](http://json-schema.org/) qui permettra de valider les "options" de notre layer;
+- Un fichier d'amorçage qui permettra à Bouncer de référencer notre nouveau layer.
+
+1. Créer le répertoire du `package` Go qui contiendra le code de votre layer. Celui ci s'appelera `basicauth`:
+
+    ```
+    mkdir -p internal/proxy/director/layer/basicauth
+    ```
+
+2. Créer la structure de base du layer:
+
+    ```go
+    // Fichier internal/proxy/director/layer/basicauth/basicauth.go
+
+    package basicauth
+
+    import (
+        proxy "forge.cadoles.com/Cadoles/go-proxy"
+        "forge.cadoles.com/cadoles/bouncer/internal/proxy/director"
+        "forge.cadoles.com/cadoles/bouncer/internal/store"
+    )
+
+    // On définit le "type" (la chaîne de caractères) qui
+    // sera associé à notre layer
+    const LayerType store.LayerType = "basicauth"
+
+    // On déclare la structure qui
+    // servira de socle pour notre layer
+    type BasicAuth struct{}
+
+    // Les deux méthodes suivantes, attachées à 
+    // notre structure BasicAuth, permettent de remplir
+    // le contrat définit par l'interface 
+    // director.MiddlewareLayer
+
+    // LayerType implements director.MiddlewareLayer.
+    func (*BasicAuth) LayerType() store.LayerType {
+        return LayerType
+    }
+
+    // C'est dans la méthode "Middleware" qu'on pourra implémenter la
+    // logique appliquée par notre layer.
+    // En l'état actuel l'exécution de la méthode provoquera un panic().
+
+    // Middleware implements director.MiddlewareLayer.
+    func (*BasicAuth) Middleware(layer *store.Layer) proxy.Middleware {
+        panic("unimplemented")
+    }
+
+    func New() *BasicAuth {
+        return &BasicAuth{}
+    }
+
+    // Cette déclaration permet de profiter
+    // des capacités du compilateur pour s'assurer
+    // que la structure BasicAuth remplie toujours le
+    // contrat imposé par l'interface director.MiddlewareLayer
+    var _ director.MiddlewareLayer = &BasicAuth{}
+    ```
+
+3. Créer le schéma JSON qui sera associé aux options possibles pour notre layer:
+
+    ```json
+    // Fichier internal/proxy/director/layer/basicauth/layer-options.json
+
+    {
+        "$id": "https://forge.cadoles.com/cadoles/bouncer/schemas/basicauth-layer-options",
+        "title": "BasicAuth layer options",
+        "type": "object",
+        "properties": {},
+        "additionalProperties": false
+    }
+    ```
+
+4. Puis créer le fichier Go qui embarquera ces données dans notre binaire via le package [`embed`](https://pkg.go.dev/embed):
+
+    ```go
+    // Fichier internal/proxy/director/layer/basicauth/layer_options.go
+
+    package basicauth
+
+    import (
+        _ "embed"
+    )
+
+    //go:embed layer-options.json
+    var RawLayerOptionsSchema []byte
+    ```
+
+5. Enfin, créer le fichier d'amorçage pour référencer notre nouveau layer avec Bouncer:
+
+    ```go
+    // Fichier internal/setup/basicauth_layer.go
+
+    package setup
+
+    import (
+        "forge.cadoles.com/cadoles/bouncer/internal/config"
+        "forge.cadoles.com/cadoles/bouncer/internal/proxy/director"
+        "forge.cadoles.com/cadoles/bouncer/internal/proxy/director/layer/basicauth"
+    )
+
+    // On créait une function d'initialisation qui enregistra les éléments suivants auprès de Bouncer:
+    // - Notre nouveau type de layer
+    // - Une fonction capable de créer une instance de notre layer
+    // - Le schéma associé aux options de notre layer
+    func init() {
+        RegisterLayer(basicauth.LayerType, setupBasicAuthLayer, basicauth.RawLayerOptionsSchema)
+    }
+
+    // La fonction de création de notre layer
+    // reçoit automatiquement la configuration actuelle de Bouncer.
+    
+    // Une layer plus avancé pourrait être configurable de cette manière
+    // en créant une nouvelle section de configuration dédiée.
+    func setupBasicAuthLayer(conf *config.Config) (director.Layer, error) {
+        return &basicauth.BasicAuth{}, nil
+    }
+    ```
+
+## Tester l'intégration de notre nouveau layer
+
+À ce stade, notre nouveau layer est normalement référencé et donc "utilisable" dans Bouncer (si on omet le fait qu'il déclenchera une `panic()`).
+
+1. Vérifier que notre layer est bien référencé en exécutant la commande:
+
+    ```
+    ./bin/bouncer admin layer create --help
+    ```
+
+    La sortie devrait ressembler à:
+
+    ```
+    NAME:
+    bouncer admin layer create - Create layer
+
+    USAGE:
+    bouncer admin layer create [command options] [arguments...]
+
+    OPTIONS:
+    --layer-type LAYER_TYPE        Set LAYER_TYPE as layer's type (available: [basicauth queue])
+    [...]
+    ```
+
+    Comme vous devriez le voir nous pouvons désormais créer des layers de type `basicauth`.
+
+2. Créer un proxy puis une instance de notre nouveau layer associée à celui ci:
+
+    ```bash
+    # Créer un proxy
+    ./bin/bouncer admin proxy create --proxy-name cadoles --proxy-to https://www.cadoles.com
+
+    # Activer celui-ci
+    ./bin/bouncer admin proxy update --proxy-name cadoles --proxy-enabled=true
+
+    # Ajouter un layer de notre nouveau type à notre proxy
+    ./bin/bouncer admin layer create --proxy-name cadoles --layer-name mybasicauth --layer-type basicauth
+
+    # Activer notre nouveau layer
+    ./bin/bouncer admin layer update --proxy-name cadoles --layer-name mybasicauth --layer-enabled=true
+    ```
+
+**Notre layer est actif** ! Cependant il est loin d'être fonctionnel. En effet, si vous faites un:
+
+```
+curl -v http://localhost:8080
+```
+
+Vous n'aurez guère en retour qu'un:
+
+```
+*   Trying 127.0.0.1:8080...
+* Connected to localhost (127.0.0.1) port 8080 (#0)
+> GET / HTTP/1.1
+> Host: localhost:8080
+> User-Agent: curl/8.1.2
+> Accept: */*
+> 
+* Empty reply from server
+* Closing connection 0
+curl: (52) Empty reply from server
+```
+
+Et également dans la console où s'exécute le service `bouncer-proxy`, vous aurez le message:
+
+```
+2023/06/23 18:39:59 http: panic serving 127.0.0.1:59868: unimplemented
+```
+
+**Il est temps d'implémenter réellement la logique associée à notre layer !**
+
+> **Note** Vous pouvez désactiver votre layer via le drapeau `--layer-enabled=false` et voir le site Cadoles s'afficher à nouveau !
+
+## Implémenter l'authentification sur notre nouveau layer
+
+Nous allons modifier la méthode `Middleware(layer *store.Layer) proxy.Middleware` attachée à notre structure `BasicAuth`.
+
+1. Modifier le fichier contenant la structure de notre layer de la manière suivante:
+
+    ```go
+    // Fichier internal/proxy/director/layer/basicauth/basicauth.go
+
+    // [...]
+
+    // Middleware implements director.MiddlewareLayer.
+    func (*BasicAuth) Middleware(layer *store.Layer) proxy.Middleware {
+        // La méthode doit retourner un "Middleware" qui est un alias
+        // pour les fonctions généralement utilisées
+        // dans les librairies http en Go pour créer
+        // une fonction d'interception/transformation de requête.
+        return func(next http.Handler) http.Handler {
+            fn := func(w http.ResponseWriter, r *http.Request) {
+                // On récupère les identifiants "basic auth" transmis (ou non)
+                // avec la requête
+                username, password, ok := r.BasicAuth()
+
+                // On créait une méthode locale pour gérer le cas d'une erreur d'authentification.
+                unauthorized := func() {
+                    // On ajoute cette entête HTTP à la réponse pour déclencher l'affichage
+                    // de la popup d'authentification dans le navigateur web de l'utilisateur.
+                    w.Header().Set("WWW-Authenticate", `Basic realm="restricted", charset="UTF-8"`)
+
+                    // On retoure un code d'erreur HTTP 401 (Unauthorized)
+                    http.Error(w, http.StatusText(http.StatusUnauthorized), http.StatusUnauthorized)
+                }
+
+                if !ok {
+                    // L'entête Authorization est absente ou ne correspondant
+                    // pas à du Basic Auth, on retourne une erreur HTTP 401 et
+                    // on interrompt le traitement de la requête ici
+                    unauthorized()
+
+                    return
+                }
+
+                // On vérifie les identifiants associés à la requête
+                isAuthenticated := authenticate(username, password)
+
+                // Si les identifiants sont non reconnus alors
+                // on interrompt le traitement de la requête
+                if !isAuthenticated {
+                    unauthorized()
+
+                    return
+                }
+
+                // L'authentification a réussie ! On passe la main au handler HTTP suivant
+                next.ServeHTTP(w, r)
+            }
+
+            return http.HandlerFunc(fn)
+        }
+    }
+
+    // La méthode authenticate() prend un couple d'identifiants
+    // est vérifie en temps constant si ceux ci correspondent à un couple
+    // d'identifiants attendus.
+    func authenticate(username, password string) bool {
+        // On génère une empreinte au format sha256 pour nos identifiants
+        usernameHash := sha256.Sum256([]byte(username))
+        passwordHash := sha256.Sum256([]byte(password))
+
+        // On effectue de même avec les identifiants attendus.
+        // Pour l'instant, on utilise un couple d'identifiants en "dur".
+        expectedUsernameHash := sha256.Sum256([]byte("foo"))
+        expectedPasswordHash := sha256.Sum256([]byte("baz"))
+
+        // On utilise la méthode subtle.ConstantTimeCompare()
+        // pour faire la comparaison des identifiants en temps constant
+        // et ainsi éviter les attaques par timing.
+        usernameMatch := (subtle.ConstantTimeCompare(usernameHash[:], expectedUsernameHash[:]) == 1)
+        passwordMatch := (subtle.ConstantTimeCompare(passwordHash[:], expectedPasswordHash[:]) == 1)
+
+        // L'utilisateur est authentifié si son nom et son mot de passe
+        // correspondent avec ceux attendus.
+        return usernameMatch && passwordMatch
+    }
+    ```
+
+2. Dans votre navigateur, essayez d'ouvrir l'URL http://127.0.0.1:8080. La popup d'authentification devrait s'afficher et vous devriez pouvoir utiliser les identifiants définis dans la fonction `authenticate()` pour vous authentifier et accéder au site de Cadoles !
+
+    > **Note** Essayez de désactiver le layer. L'authentification est automatiquement désactivée également !
+
+## Déclarer des options pour pouvoir utiliser des identifiants dynamiques
+
+En l'état actuel notre layer est fonctionnel. Cependant il souffre d'un problème notable: les identifiants attendus sont statiques et embarqués en dur dans le code. Nous allons utiliser le schéma associé à nos options, jusqu'alors vide, pour pouvoir créer une paire d'identifiants attendus dynamique.
+
+
+1. Modifier le schéma JSON des options de notre layer:
+
+    ```json
+    // Fichier internal/proxy/director/layer/basicauth/layer-options.json
+
+    {
+        "$id": "https://forge.cadoles.com/cadoles/bouncer/schemas/basicauth-layer-options",
+        "title": "BasicAuth layer options",
+        "type": "object",
+        "properties": {
+            "username": {
+                "type": "string"
+            },
+            "password": {
+                "type": "string"
+            }
+        },
+        "additionalProperties": false
+    }
+    ```
+
+2. On modifie notre méthode `Middleware()` et la fonction `authenticate()` pour utiliser ces nouvelles options:
+
+    ```go
+    package basicauth
+
+    import (
+        "crypto/sha256"
+        "crypto/subtle"
+        "net/http"
+
+        proxy "forge.cadoles.com/Cadoles/go-proxy"
+        "forge.cadoles.com/cadoles/bouncer/internal/proxy/director"
+        "forge.cadoles.com/cadoles/bouncer/internal/store"
+        "gitlab.com/wpetit/goweb/logger"
+    )
+
+    const LayerType store.LayerType = "basicauth"
+
+    type BasicAuth struct{}
+
+    // LayerType implements director.MiddlewareLayer.
+    func (*BasicAuth) LayerType() store.LayerType {
+        return LayerType
+    }
+
+    // Middleware implements director.MiddlewareLayer.
+    func (*BasicAuth) Middleware(layer *store.Layer) proxy.Middleware {
+        // La méthode doit retourner un "Middleware" qui est un alias
+        // pour les fonctions généralement utilisées
+        // dans les librairies http en Go pour créer
+        // une fonction d'interception/transformation de requête.
+        return func(next http.Handler) http.Handler {
+            fn := func(w http.ResponseWriter, r *http.Request) {
+                // On récupère les identifiants "basic auth" transmis (ou non)
+                // avec la requête
+                username, password, ok := r.BasicAuth()
+
+                // On créait une méthode locale pour gérer le cas d'une erreur d'authentification.
+                unauthorized := func() {
+                    // On ajoute cette entête HTTP à la réponse pour déclencher l'affichage
+                    // de la popup d'authentification dans le navigateur web de l'utilisateur.
+                    w.Header().Set("WWW-Authenticate", `Basic realm="restricted", charset="UTF-8"`)
+
+                    // On retoure un code d'erreur HTTP 401 (Unauthorized)
+                    http.Error(w, http.StatusText(http.StatusUnauthorized), http.StatusUnauthorized)
+                }
+
+                if !ok {
+                    // L'entête Authorization est absente ou ne correspondant
+                    // pas à du Basic Auth, on retourne une erreur HTTP 401 et

+                    http.Error(w, http.StatusText(http.StatusInternalServerError), http.StatusInternalServerError)
+

+
+                // On vérifie les identifiants associés à la requête

+    ```
+
+3. Modifiez votre layer via la commande d'administration pour déclarer une paire d'identifiants:
+
+    ```bash
+    ./bin/bouncer admin layer update --proxy-name cadoles --layer-name mybasicauth --layer-options='{"username":"jdoe","password":"notsosecret"}'
+    ```
+
+4. Essayer d'accéder à l'adresse http://127.0.0.1:8080 avec votre navigateur. La popup d'authentification devrait s'afficher et vous devriez pouvoir vous authentifier avec le nouveau couple d'identifiants définis dans les options de votre layer !
+
+> **Note** Vous pouvez modifier les identifiants plusieurs fois via la commande et vérifier que la fenêtre s'affiche toujours à nouveau, demandant les nouveaux identifiants.

+# Démarrer avec les sources
+
+Dans ce tutoriel, nous verrons comment lancer un environnement de développement en local sur notre machine afin de travailler sur les sources de Bouncer.
+
+## Prérequis
+
+Les éléments suivants doivent être installés sur votre machine:
+
+- [Golang > 1.20](https://go.dev/)
+- [Docker](https://www.docker.com/)
+- [Git](https://git-scm.com/)
+- [GNU Make](https://www.gnu.org/software/make/)
+
+Les ports suivants doivent être disponibles sur votre machine:
+
+- `8080`
+- `8081`
+
+## Étapes
+
+1. Cloner le dépôt des sources du projet Bouncer
+
+    ```
+    git clone https://forge.cadoles.com/Cadoles/bouncer
+    ```
+
+2. Se positionner dans le répertoire du projet
+
+    ```
+    cd bouncer
+    ```
+
+3. Lancer le projet en mode "développement"
+
+    ```
+    make watch
+    ```
+
+Si toutes les dépendances sont correctement installées et configurées sur votre machine, la console devrait afficher une série de messages pour ensuite s'arrêter sur quelque chose ressemblant à:
+
+```

To fix this issue add 'vm.overcommit_memory = 1' to /etc/sysctl.conf and then reboot or run the command 'sysctl vm.overcommit_memory=1' for this to take effect
+```
+
+À ce stade, le serveur `bouncer-admin` écoute sur http://127.0.0.1:8081 et le serveur `bouncer-proxy` sur http://127.0.0.1:8080.
+
+> **Note**
+> 
+> L'outil [`modd`](https://github.com/cortesi/modd) est utilisé pour surveiller les modifications sur les sources et relancer automatiquement la compilation et les services en cas de changement.
+
+## Commandes `make` utiles
+
+### `make watch`
+
+Surveiller les sources, compiler celles ci en cas de modifications et lancer les services `bouncer-proxy` et `bouncer-admin`.
+
+### `make test`
+
+Exécuter les tests unitaires/d'intégration du projet.
+
+### `make build`
+
+Compiler une version de développement du binaire `bouncer`.
+
+### `make docker-build`
+
+Construire une image Docker pour Bouncer.
+
+Vous pouvez ensuite lancer l'image localement avec la commande:
+
+```
+docker run \
+    -it --rm \
+    reg.cadoles.com/cadoles/bouncer:<tag> \
+    -p 8080:8080 \
+    bouncer server proxy run
+```
+
+### `make grafterm`
+
+Afficher un tableau de bord [`grafterm`](https://github.com/slok/grafterm) branché sur l'instance Prometheus locale.
+
+### `make siege`
+
+Lancer une session de test [`siege`](https://github.com/JoeDog/siege) sur l'instance `bouncer-proxy` locale.

+# Intégration avec Kubernetes
+
+Dans le cadre du déploiement de Bouncer dans un environnement Kubernetes, il est possible d'activer un mode d'intégration permettant à Bouncer d'exposer des jetons d'authentification directement sous forme de [`Secret`](https://kubernetes.io/fr/docs/concepts/configuration/secret/).
+
+L'activation et configuration de l'intégration Kubernetes s'effectue dans le fichier de configuration du serveur d'administration via la section `integrations.kubernetes`:
+
+```yaml
+# Section de configuration des intégrations
+# avec des produits externes
+integrations:
+  # Intégration avec Kubernetes
+  kubernetes:
+    # Activer/désactiver l'intégration Kubernetes
+    enabled: true
+    # Créer/mettre à jour un Secret automatiquement avec un jeton d'authentification
+    # avec le rôle "writer".
+    # Désactivé si l'attribut est vide ou absent.
+    writerTokenSecret: my-bouncer-admin-writer-token
+    # Namespace de destination du Secret pour le jeton d'authentification
+    # avec le rôle "reader".
+    # Utilise par défaut le namespace courant si absent ou vide.
+    writerTokenSecretNamespace: "my-namespace"
+    # Créer/mettre à jour un Secret automatiquement avec un jeton d'authentification
+    # avec le rôle "reader".
+    # Désactivé si l'attribut est vide ou absent.
+    readerTokenSecret: my-bouncer-admin-reader-token
+    # Namespace de destination du Secret pour le jeton d'authentification
+    # avec le rôle "reader".
+    # Utilise par défaut le namespace courant si absent ou vide.
+    readerTokenSecretNamespace: "my-namespace"
+    # Délai maximum alloué au verrou distribué pour la mise à jour
+    # des secrets.
+    lockTimeout: 30s
+```
+
+Vous devrez également définir un `ServiceAccount` pour votre `Pod` avec un `Role` équivalent au suivant (dans le cas nominal où le `Pod` créait les `Secrets` dans son même namespace):
+
+```yaml
+apiVersion: rbac.authorization.k8s.io/v1
+kind: Role
+metadata:
+  name: bouncer-admin
+rules:
+  - apiGroups:
+      - ""
+      - v1
+    resources:
+      - secrets
+    verbs:
+      - create
+      - get
+      - update
+```
+
+> **Note**
+>
+> La génération des jetons d'authentification s'effectue à chaque démarrage du serveur d'administration. Un verrou partagé permet d'éviter que plusieurs instances fonctionnant en parallèle essayent de mettre à jour les ressources Kubernetes au même moment.
+>
+> De plus, les jetons seront laissés en l'état si la clé de génération n'a pas été modifiée pour éviter de changer les jetons à chaque redémarrage d'un `Pod` (voir l'annotation `bouncer.cadoles.com/public-key` sur les `Secrets` créés.).
+
+Un exemple fonctionnel de déploiement Kubernetes est disponible dans le répertoire `misc/k8s` du projet.

+# 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.
