Fragmentos de plantillas de Amazon Redshift

Amazon Redshift es un servicio de almacenamiento de datos administrado a escala de petabytes en la nube . Puede usar AWS CloudFormation para aprovisionar y administrar clústeres de Amazon Redshift.

Clúster de Amazon Redshift

La siguiente plantilla de ejemplo crea un clúster de Amazon Redshift de acuerdo con los valores de los parámetros que se especifican cuando se crea la pila. El grupo de parámetros del clúster que se asocia con el clúster de Amazon Redshift permite el registro de la actividad del usuario. La plantilla también lanza clústeres de Amazon Redshift en una Amazon VPC que se define en la plantilla. La VPC incluye una gateway de Internet para que pueda acceder a los clústeres de Amazon Redshift desde Internet. Sin embargo, la comunicación entre el clúster y el puerto de enlace a Internet deben estar habilitada, lo que se realiza en la tabla de ruteo.

nota

La plantilla incluye la condición IsMultiNodeCluster, de modo que el parámetro NumberOfNodes se declara solo cuando el valor del parámetro ClusterType está establecido en multi-node.

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 como asteriscos (*****) para cualquier llamada que describa la pila o los eventos de la pila, excepto para la información almacenada en las ubicaciones especificadas a continuación.

importante

El uso del atributo NoEcho no enmascara ninguna información almacenada en lo que se muestra a continuación:

• La sección de la plantilla Metadata. CloudFormation no transforma, modifica ni redacta ninguna información que incluya en la sección Metadata. Para obtener más información, consulte Metadatos.

• La sección de la plantilla Outputs. Para obtener más información, consulte Salidas.

• El atributo Metadata de una definición de recurso. Para obtener más información, consulte Atributo Metadata.

Recomendamos encarecidamente que no utilice estos mecanismos para incluir información confidencial, como contraseñas o secretos.

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.

Para obtener más información, consulte las Prácticas recomendadas de No integre credenciales en sus plantillas.
