Fragmentos de plantillas de AWS OpsWorks

AWS OpsWorks es un servicio de administración de aplicaciones que simplifica una amplia gama de tareas como la configuración de software, la implementación de aplicaciones, el escalado y la monitorización. CloudFormation es un servicio de administración de recursos que puede utilizar para administrar recursos de AWS OpsWorks, como, por ejemplo, pilas de AWS OpsWorks, capas, aplicaciones e instancias.

Aplicación PHP de ejemplo de AWS OpsWorks

La siguiente plantilla de ejemplo implementa una aplicación web PHP de AWS OpsWorks almacenada en un repositorio Git público. La pila de AWS OpsWorks incluye dos servidores de aplicaciones con un balanceador de carga que distribuye el tráfico entrante de manera uniforme entre los servidores. La pila de AWS OpsWorks también incluye un servidor back-end de base de datos de MySQL para almacenar datos. Para obtener más información acerca de la aplicación de AWS OpsWorks de ejemplo, consulte Tutorial para aprender los fundamentos de AWSAWS OpsWorks creando una pila de servidores de aplicaciones en la Guía del usuario de AWS OpsWorks.

nota

Las propiedades ServiceRoleArn y DefaultInstanceProfileArn hacen referencia a roles de IAM que se crean después de utilizar AWS OpsWorks por primera vez.

El ejemplo define el parámetro MysqlRootPassword con la propiedad NoEcho establecida en true. Si establece el atributo NoEcho en true, CloudFormation devuelve el valor del parámetro enmascarado con asteriscos (*****) para todas las llamadas que describan la pila o los eventos de pila.

importante

En lugar de integrar información confidencial directamente en las plantillas de CloudFormation, se recomienda utilizar parámetros dinámicos en la plantilla de la pila para hacer referencia a la información confidencial almacenada y administrada fuera de CloudFormation, como en AWS Systems Manager Parameter Store o AWS Secrets Manager.
