AWS CloudFormation: no se pueden adjuntar los grupos de seguridad a las instancias de ElasticBeanstalk

Aug 18 2020

Estoy implementando mi aplicación Laravel en AWS usando CloudFormation. Estoy creando un entorno ElasticBeanstalk y desplegando mi aplicación en él. Pero cuando intenté adjuntar el grupo de seguridad a las instancias, falló.

Esta es mi plantilla.

Como puede ver, hay un recurso WebServerSecurityGroup en mi plantilla y lo adjunto al recurso Beanstalk de la siguiente manera.

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

Cuando lo implemento, está fallando. Pero si no adjunto el grupo de seguridad, la implementación es exitosa. ¿Qué está mal con mi código y cómo puedo solucionarlo?

Este es el error en el registro.

El motivo por el que WebServerSecurityGroupno se encuentra (SG) es porque está creando el SG en una VPC diferente a su entorno de EB. Específicamente, está almorzando EB en una VPC predeterminada, mientras que parece estar creando su SG en una VPC diferente como se especifica en la siguiente línea:

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

Dado que no está claro qué está haciendo con la VPC (¿está iniciando EB en una VPC personalizada, creando una nueva VPC o utilizando la VPC predeterminada?), La solución más sencilla para su plantilla es simplemente eliminar el VpcId: !Ref Vpc.

Además, la versión de su plataforma está desactualizada y debe cambiarse. La lista de versiones de la plataforma PHP disponibles está aquí .

Me fijo de la plantilla y puedo comprobar que funciona en us-east-1. Lanza EB y su SG en a default VPC. Para la VPC personalizada, se requieren muchos más cambios en su plantilla, como definiciones de subredes, tablas de enrutamiento y cambios específicos de VPC en el propio entorno de EB.

Después de revisar una plantilla de ejemplo , parece que la configuración requiere una opción VpcId, Subnetsy ELBSubnetspara permitir que la configuración de EB se una a una VPC en lugar de crear la suya propia.

Además, estaba usando una versión anterior de SolutionStackName, debería ser 64bit Amazon Linux 2018.03 v2.9.9 running PHP 7.2.

También noté que su beneficio puede hacer uso de los parámetros de AWS para el ID de VPC y el nombre de la clave en lugar de la codificación rígida, lo que mejorará la usabilidad de la interfaz.
