Los *conceptos básicos* son ejemplos de código que muestran cómo realizar las operaciones esenciales dentro de un servicio. Las *acciones* son extractos de código de programas más grandes y deben ejecutarse en contexto. Mientras las acciones muestran cómo llamar a las distintas funciones de servicio, es posible ver las acciones en contexto en los escenarios relacionados. Los *escenarios* son ejemplos de código que muestran cómo llevar a cabo una tarea específica a través de llamadas a varias funciones dentro del servicio o combinado con otros Servicios de AWS. **Más recursos** + **[Guía del usuario de escalado automático](https://docs.aws.amazon.com/autoscaling/ec2/userguide/what-is-amazon-ec2-auto-scaling.html)**: más información sobre el escalado automático. + **[Referencia de la API de escalado automático](https://docs.aws.amazon.com/autoscaling/ec2/APIReference/Welcome.html)**: información sobre todas las acciones de escalado automático disponibles. + **[AWS Centro de desarrolladores](https://aws.amazon.com/developer/code-examples/?awsf.sdk-code-examples-product=product%23ec2-auto-scaling)**: ejemplos de código que puede filtrar por categoría o por búsqueda de texto completo. + **[AWS Ejemplos de SDK](https://github.com/awsdocs/aws-doc-sdk-examples)**: GitHub repositorio con código completo en los idiomas preferidos.

Las instancias se lanzan con la versión predeterminada de la plantilla de lanzamiento especificada. Tenga en cuenta que se utilizan valores predeterminados para la mayoría de las demás configuraciones, como las políticas de terminación y la configuración de las comprobaciones de estado. ``` aws autoscaling create-auto-scaling-group \ --auto-scaling-group-name my-asg \ --launch-template LaunchTemplateId=lt-1234567890abcde12 \ --min-size 1 \ --max-size 5 \ --vpc-zone-identifier "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782" ``` Este comando no genera ninguna salida. Para obtener más información, consulte [Grupos de escalado automático](https://docs.aws.amazon.com/autoscaling/ec2/userguide/AutoScalingGroup.html) en la *Guía del usuario de Amazon EC2 Auto Scaling*. **Ejemplo 2: asociar un equilibrador de carga de aplicación, un equilibrador de carga de red o un equilibrador de carga de puerta de enlace** En este ejemplo, se especifica el ARN de un grupo de destino para un equilibrador de carga que admite el tráfico esperado. El tipo de comprobación de estado especifica `ELB` para que, cuando Elastic Load Balancing informa de una instancia como en mal estado, el grupo de escalado automático reemplaza la instancia. El comando también define un período de gracia de `600` segundos para la comprobación de estado. El período de gracia ayuda a evitar la finalización prematura de las instancias recién lanzadas. ``` aws autoscaling create-auto-scaling-group \ --auto-scaling-group-name my-asg \ --launch-template LaunchTemplateId=lt-1234567890abcde12 \ --target-group-arns arn:aws:elasticloadbalancing:us-west-2:123456789012:targetgroup/my-targets/943f017f100becff \ --health-check-type ELB \ --health-check-grace-period 600 \ --min-size 1 \ --max-size 5 \ --vpc-zone-identifier "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782" ``` Este comando no genera ninguna salida. Para obtener más información, consulte [Elastic Load Balancing y Amazon EC2 Auto Scaling](https://docs.aws.amazon.com/autoscaling/ec2/userguide/autoscaling-load-balancer.html) en la *Guía del usuario de Amazon EC2 Auto Scaling*. **Ejemplo 3: especificación de un grupo con ubicación y utilizar la versión más reciente de la plantilla de lanzamiento** En este ejemplo, se lanzan instancias a un grupo con ubicación en una única zona de disponibilidad. Esto puede resultar útil para grupos de baja latencia con cargas de trabajo de HPC. En este ejemplo, también se especifican el tamaño mínimo, el tamaño máximo y la capacidad deseada del grupo. ``` aws autoscaling create-auto-scaling-group \ --auto-scaling-group-name my-asg \ --launch-template LaunchTemplateId=lt-1234567890abcde12,Version='$Latest' \ --min-size 1 \ --max-size 5 \ --desired-capacity 3 \ --placement-group my-placement-group \ --vpc-zone-identifier "subnet-6194ea3b" ``` Este comando no genera ninguna salida. Para obtener más información, consulte [Grupos de ubicación](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html) en la *Guía del usuario de Amazon EC2 para instancias Linux*. **Ejemplo 4: especificación de un grupo de escalado automático de una sola instancia y utilizar una versión específica de la plantilla de lanzamiento** En este ejemplo, se crea un grupo de escalado automático con una capacidad mínima y máxima establecida en `1` para garantizar que se ejecute una instancia. El comando también especifica la v1 de una plantilla de lanzamiento en la que se especifica el ID de un ENI existente. Cuando utilice una plantilla de lanzamiento que especifique un ENI existente para eth0, debe especificar una zona de disponibilidad para el grupo de escalado automático que coincida con la interfaz de red, sin especificar también un ID de subred en la solicitud. ``` aws autoscaling create-auto-scaling-group \ --auto-scaling-group-name my-asg-single-instance \ --launch-template LaunchTemplateName=my-template-for-auto-scaling,Version='1' \ --min-size 1 \ --max-size 1 \ --availability-zones us-west-2a ``` Este comando no genera ninguna salida. Para obtener más información, consulte [Grupos de escalado automático](https://docs.aws.amazon.com/autoscaling/ec2/userguide/AutoScalingGroup.html) en la *Guía del usuario de Amazon EC2 Auto Scaling*. **Ejemplo 5: especificación de una política de terminación diferente** En este ejemplo, se crea un grupo de escalado automático mediante una configuración de lanzamiento y se establece la política de terminación para terminar primero las instancias más antiguas. El comando también aplica una etiqueta al grupo y a sus instancias, con una clave de `Role` y un valor de `WebServer`. ``` aws autoscaling create-auto-scaling-group \ --auto-scaling-group-name my-asg \ --launch-configuration-name my-lc \ --min-size 1 \ --max-size 5 \ --termination-policies "OldestInstance" \ --tags "ResourceId=my-asg,ResourceType=auto-scaling-group,Key=Role,Value=WebServer,PropagateAtLaunch=true" \ --vpc-zone-identifier "subnet-5ea0c127,subnet-6194ea3b,subnet-c934b782" ``` Este comando no genera ninguna salida.
