AWS CloudFormation: impossible d'attacher les groupes de sécurité aux instances d'ElasticBeanstalk

Aug 18 2020

Je déploie mon application Laravel sur AWS à l'aide de CloudFormation. Je crée un environnement ElasticBeanstalk et y déploie mon application. Mais lorsque j'ai essayé d'attacher le groupe de sécurité aux instances, cela échoue.

Ceci est mon modèle.

Comme vous pouvez le voir, il existe une ressource WebServerSecurityGroup dans mon modèle et je l'attache à la ressource Beanstalk comme suit.

- Namespace: aws:autoscaling:launchconfiguration
              OptionName: SecurityGroups
              Value:
                Ref: WebServerSecurityGroup

Quand je le déploie, il échoue. Mais si je n'attache pas le groupe de sécurité, le déploiement est réussi. Quel est le problème avec mon code et comment puis-je y remédier?

C'est l'erreur dans le journal.

La raison pour laquelle WebServerSecurityGroup(SG) n'est pas trouvé est que vous créez le SG dans un VPC différent de votre environnement EB. Plus précisément, vous déjeunez EB dans un VPC par défaut, alors que vous semblez créer votre SG dans différents VPC comme spécifié dans la ligne suivante:

      VpcId: !Ref Vpc # <--- your EB will be in different VPC than your SG

Comme ce que vous faites avec le VPC n'est pas clair (lancez-vous EB dans un VPC personnalisé, créez-vous un nouveau VPC ou utilisez-vous un VPC par défaut?), La solution la plus simple à votre modèle consiste simplement à supprimer le VpcId: !Ref Vpc.

La version de votre plate - forme est également obsolète et doit être modifiée. La liste des versions de plate-forme PHP disponibles est ici .

J'ai corrigé le modèle et je peux vérifier qu'il fonctionne dans us-east-1. Il lance EB et son SG dans un default VPC. Pour un VPC personnalisé, de nombreuses autres modifications sont nécessaires à votre modèle, telles que les définitions des sous-réseaux, les tables de routage et les modifications spécifiques au VPC de l'environnement EB lui-même.

Après avoir parcouru un exemple de modèle, il semble que la configuration nécessite une option VpcId, Subnetset ELBSubnetspour permettre à la configuration EB de rejoindre un VPC plutôt que de créer le sien.

De plus, vous utilisiez une version précédente de SolutionStackName, ça devrait être 64bit Amazon Linux 2018.03 v2.9.9 running PHP 7.2.

J'ai également remarqué que vous pouvez utiliser les paramètres AWS pour l'ID de VPC et le nom de la clé plutôt qu'un codage en dur, ce qui améliorera la convivialité de l'interface.

Le modèle ci-dessous corrige ce qui précède
