Ajouter ou supprimer des listeners

Vous pouvez ajouter un ou plusieurs listeners à un load balancer et les supprimer à tout moment si vous n’en avez plus besoin. Ajouter un listener à un load balancer lui permet d’écouter des flux entrants sur un port et dans un protocole que vous spécifiez, et d’envoyer la charge réseau vers les machines virtuelles (VM) backend en utilisant un port et un protocole que vous spécifiez également.

Vous pouvez configurer uniquement un type de health checks par load balancer en spécifiant le port et le protocole des VM backend à vérifier. Nous vous recommandons donc de créer un load balancer par service pour éviter qu’une panne ne soit pas détectée, vos listeners devant donc envoyer la charge réseau vers les VM backend en utilisant le même port et le même protocole.

Vous ne pouvez pas modifier un listener existant. La seule façon de modifier le port et le protocole utilisé du côté du load balancer ou du côté des VM backend est d’ajouter un listener avec la configuration appropriée, et de supprimer le précédent si besoin.

Ajouter ou supprimer des listeners avec AWS CLI

Avant de commencer : Installez et configurez AWS CLI. Pour en savoir plus, voir Installer et configurer AWS CLI.

Ajouter un listener à un load balancer

Pour ajouter un ou plusieurs listeners à un load balancer, utilisez la commande create-load-balancer-listeners en suivant cette syntaxe :

Exemple de requête
$ aws elb create-load-balancer-listeners \
    --profile YOUR_PROFILE \
     --load-balancer-name LOAD_BALANCER_NAME \
    --listeners Protocol=TCP,LoadBalancerPort=62,InstanceProtocol=TCP,InstancePort=58 \
    --endpoint https://lbu.eu-west-2.outscale.com

Cette commande contient les options suivantes que vous devez spécifier :

  • (optionnel) profile : Le profil nommé que vous voulez utiliser, créé pendant la configuration d’AWS CLI. Pour en savoir plus, voir Installer et configurer AWS CLI.

  • load-balancer-name : Le nom du load balancer.

  • listeners : Un ou plusieurs listeners pour le load balancer. Cette option requiert les éléments suivants pour chaque listener :

    Pour ajouter plusieurs listeners, séparez-les à l’aide d’une espace.

    • Protocol : Le protocole de routage pour le load balancer (HTTP, HTTPS, TCP ou SSL).

    • LoadBalancerPort : Le port sur lequel le load balancer écoute (entre 1 et 65535, tous deux inclus).

    • InstancePort : Le port sur lequel les instances backend écoutent (entre 1 et 65535, tous deux inclus).

    • (optionnel) InstanceProtocol : Le protocole utilisé pour router le trafic vers les instances backend (HTTP, HTTPS, TCP ou SSL).

    • (optionnel) SSLCertificateId : L’OUTSCALE Resource Name (ORN) d’un certificat SSL. Pour en savoir plus, voir Obtenir des informations sur vos certificats serveur.

      Un certificat SSL est requis si le protocole du load balancer est HTTPS ou SSL.

Pour en savoir plus sur comment configurer votre listener lorsque vous utilisez des certificats SSL, voir Configurer un load balancer pour une redirection SSL.

  • endpoint : Le endpoint correspondant à la Région à laquelle vous voulez envoyer la requête. Pour en savoir plus, voir Installer et configurer AWS CLI.

Les listeners que vous avez spécifiés sont ajoutés au load balancer.

Supprimer un listener d’un load balancer

Pour supprimer un ou plusieurs listeners d’un load balancer, utilisez la commande delete-load-balancer-listeners en suivant cette syntaxe :

Exemple de requête
$ aws elb delete-load-balancer-listeners \
    --profile YOUR_PROFILE \
    --load-balancer-name LOAD_BALANCER-NAME \
    --load-balancer-ports 80 44 \
    --endpoint https://lbu.eu-west-2.outscale.com

Cette commande contient les options suivantes que vous devez spécifier :

  • (optionnel) profile : Le profil nommé que vous voulez utiliser, créé pendant la configuration d’AWS CLI. Pour en savoir plus, voir Installer et configurer AWS CLI.

  • load-balancer-name : Le nom du load balancer.

  • load-balancer-ports : Un ou plusieurs ports correspondant aux listeners que vous souhaitez supprimer.

    Pour supprimer plusieurs listeners, séparez les avec un espace.

  • endpoint : Le endpoint correspondant à la Région à laquelle vous voulez envoyer la requête. Pour en savoir plus, voir Installer et configurer AWS CLI.

Les listeners que vous avez spécifiés sont supprimés du load balancer.
