Avant de commencer : Assurez-vous que les security groups de vos VM backend autorisent les flux venant d’une autre source que le load balancer.

Le nom DNS sera supprimé.

  1. Dans le dashboard Load Balancers, cochez la case du load balancer que vous voulez supprimer.

    La multisélection est disponible.

    Le load balancer est sélectionné.

  2. Cliquez sur IconTerminate Supprimer.
    Une boîte de dialogue de confirmation apparaît.

The DeleteLoadBalancer command deletes a specified load balancer.

Request sample
$ osc-cli api DeleteLoadBalancer --profile "default" \

Supprimer un load balancer avec AWS CLI

Avant de commencer :

  • Installez et configurez AWS CLI. Pour en savoir plus, voir Installer et configurer AWS CLI.

  • Assurez-vous que les security groups de vos instances backend autorisent les flux venant d’une autre source que le load balancer.

Pour supprimer un load balancer, utilisez la commande delete-load-balancer en suivant cette syntaxe :

Exemple de requête
$ aws elb delete-load-balancer \
    --profile YOUR_PROFILE \
    --load-balancer-name My-load-balancer \
    --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.

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

Le load balancer est supprimé.
