¿Cómo puedo utilizar las plantillas de lanzamiento para instalar automáticamente el agente de CodeDeploy en una instancia de Amazon EC2 que ejecute Amazon Linux o Ubuntu?

Resolución

Al crear una plantilla de lanzamiento, puede usar el campo User data para añadir un script de configuración que se ejecute cuando se inicie la instancia. El script de shell instala el agente CodeDeploy en todas las regiones de AWS y en las distribuciones de Amazon Linux y Ubuntu compatibles.

Para configurar CodeDeploy para que se actualice automáticamente al arrancar, defina la variable AUTOUPDATE como true. Por ejemplo, añada el siguiente script de configuración en el campo User data de Amazon EC2 en función de la versión de metadatos de la instancia.

Importante: El siguiente script solo funciona en EC2 para Linux. En entornos Windows, el script falla.
