# Uso de Amazon ECS con AWS CloudFormation
<a name="ecs-with-cloudformation"></a>

Amazon ECS está integrado con AWS CloudFormation, un servicio que puede utilizar para modelar y configurar recursos de AWS con plantillas que defina. CloudFormation usa **plantillas** con formato de archivo de texto `YAML` o `JSON`. Las plantillas son como esquemas del recurso de AWS que desea crear. Al crear y enviar una plantilla, CloudFormation crea una **pila**. Los recursos definidos en su plantilla se administran a través de la pila. Cuando desee crear, actualizar o eliminar un recurso, debe crear, actualizar o eliminar la pila que se ha creado a partir de ese recurso. Cuando se trata de actualizar las pilas, primero debe crear un **conjunto de cambios**. Los conjuntos de cambios le muestran qué es lo que se ve afectado por el cambio antes de que lo realice. Por ejemplo, esto evita que elimine bases de datos de manera accidental al cambiar el nombre de la base de datos. Para obtener más información sobre plantillas, pilas y conjuntos de cambios, consulte [Cómo funciona CloudFormation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cloudformation-overview.html#cfn-concepts-stacks) en la *Guía del usuario AWS CloudFormation*.

Al utilizar CloudFormation, puede dedicar menos tiempo a crear y administrar sus recursos e infraestructura. Puede crear una plantilla que describa todos los recursos de AWS que desee, como clústeres, definiciones de tareas y servicios de Amazon ECS. A continuación, CloudFormation se encarga de aprovisionar y configurar esos recursos para usted. 

CloudFormation también le permite volver a usar la plantilla para configurar los recursos de Amazon ECS de forma coherente y repetida. Solo tiene que describir los recursos una vez y luego aprovisionar de nuevo los mismos recursos a lo largo de varios Cuentas de AWS y Regiones de AWS.

Las plantillas de CloudFormation se pueden utilizar tanto con la Consola de administración de AWS como la AWS Command Line Interface para crear recursos.

# Creación de recursos de Amazon ECS con la consola de CloudFormation
<a name="ecs-cloudformation-console"></a>

Una forma de utilizar Amazon ECS con CloudFormation es a través de la Consola de administración de AWS. Aquí puede crear sus pilas de CloudFormation para los componentes de Amazon ECS, como definiciones de tareas, clústeres y servicios, e implementarlos directamente desde la consola. El siguiente tutorial muestra cómo puede utilizar la consola de CloudFormation para crear recursos de Amazon ECS con una plantilla.

## Requisitos previos
<a name="ecs-cloudformation-console-prerequisites"></a>

En este tutorial se supone que los siguientes requisitos previos se han completado.
+ Se han completado los pasos que se indican en [Configuración para utilizar Amazon ECS](get-set-up-for-amazon-ecs.md).
+ Su usuario de IAM dispone de los permisos requeridos que se especifican en la política de IAM [AmazonECS\$1FullAccess](security-iam-awsmanpol.md#security-iam-awsmanpol-AmazonECS_FullAccess) de ejemplo.

## Paso 1: creación de una plantilla de pila
<a name="ecs-cloudformation-create-template-file"></a>

Siga estos pasos para crear una plantilla de pila de CloudFormation para un servicio de Amazon ECS y otros recursos relacionados.

1. Con el editor de texto que desee, cree un archivo llamado `ecs-tutorial-template.yaml`.

1. En el archivo `ecs-tutorial-template.yaml`, pegue la siguiente plantilla y guarde los cambios.

    La plantilla utilizada en este tutorial crea un servicio de Amazon ECS con dos tareas que se ejecutan en Fargate. Cada una de las tareas ejecuta una aplicación de Amazon ECS de ejemplo. La plantilla también crea un equilibrador de carga de aplicación que distribuye el tráfico de la aplicación y una política de escalado automático de la aplicación que escala la aplicación en función del uso de la CPU. La plantilla también crea los recursos de red necesarios para implementar la aplicación, los recursos de registro para los registros de contenedores y un rol de IAM de ejecución de tareas de Amazon ECS. Para obtener más información sobre el rol de ejecución de tareas, consulte [Rol de IAM de ejecución de tareas de Amazon ECS](task_execution_IAM_role.md). Para obtener más información sobre el escalado automático, consulte [Escalado automático de su servicio de Amazon ECS](service-auto-scaling.md).

## Paso 2: creación de una pila para recursos de Amazon ECS
<a name="ecs-cloudformation-create-stack"></a>

Después de crear un archivo para la plantilla, puede seguir estos pasos para crear una pila con la plantilla mediante la consola de CloudFormation.

Para obtener más información sobre cómo crear una pila mediante la consola de CloudFormation, consulte [Creación de una pila en la consola CloudFormation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-console-create-stack.html) en la *Guía del usuario de AWS CloudFormation* y utilice la siguiente tabla para determinar qué opciones especificar.


| Opción | Valor | 
| --- | --- | 
|  Requisito previo: preparar la plantilla  | Elegir una plantilla existente | 
| Especificar plantilla |  Upload a template file (Cargar un archivo de plantilla)  | 
| Seleccionar archivo |  ecs-tutorial-template.yaml  | 
| Nombre de pila |  ecs-tutorial-stack  | 
| Parameters |  Deje los valores de los parámetros como predeterminados.  | 
| Capacidades |  Elija **Confirmo que esta plantilla pueda crear recursos de IAM** para confirmar que CloudFormation puede crear recursos de IAM.  | 

## Paso 3: verificación
<a name="ecs-cloudformation-verify"></a>

Siga los pasos que se indican a continuación para verificar la creación de los recursos de Amazon ECS mediante la plantilla proporcionada.

Para obtener más información sobre cómo ver los datos y los recursos de la pila, consulte [Visualización de la información de la pila desde la consola de CloudFormation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-console-view-stack-data-resources.html) en la *Guía del usuario de AWS CloudFormation* y utilice la siguiente tabla para determinar qué se debe verificar.


| Campo de detalles de la pila | Qué buscar | 
| --- | --- | 
|  Stack info (Info de la pila)  | Un estado de CREATE\$1COMPLETE. | 
| Recursos |  Una lista de los recursos creados con enlaces a la consola del servicio. Seleccione los enlaces a `ECSCluster`, `ECSService`, `TaskDefinition` para ver más detalles sobre el servicio, el clúster y la definición de tarea creados en la consola de Amazon ECS.  | 
| Salidas |  **LoadBalancerURL**. Pegue la URL en un navegador web para ver una página web que muestre un ejemplo de la aplicación de Amazon ECS.  | 

## Paso 4: limpie los recursos
<a name="ecs-cloudformation-console-cleanup"></a>

Para reducir los recursos y evitar incurrir en costos adicionales, siga los pasos que se detallan en [Eliminar una pila de la consola de CloudFormation](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/cfn-console-delete-stack.html) de la *Guía del usuario de CloudFormation*.

# Creación de recursos de Amazon ECS con comandos de la AWS CLI para CloudFormation
<a name="ecs-cloudformation-cli"></a>

Otra forma de utilizar Amazon ECS con CloudFormation es a través de la AWS CLI. Puede usar comandos para crear sus pilas de CloudFormation para los componentes de Amazon ECS, como definiciones de tareas, clústeres y servicios, e implementarlos. El siguiente tutorial muestra cómo puede utilizar la AWS CLI para crear recursos de Amazon ECS con una plantilla de CloudFormation.

## Requisitos previos
<a name="ecs-cloudformation-cli-prerequisite"></a>
+ Se han completado los pasos que se indican en [Configuración para utilizar Amazon ECS](get-set-up-for-amazon-ecs.md).
+ Su usuario de IAM dispone de los permisos requeridos que se especifican en la política de IAM [AmazonECS\$1FullAccess](security-iam-awsmanpol.md#security-iam-awsmanpol-AmazonECS_FullAccess) de ejemplo.

## Paso 1: creación de una pila
<a name="ecs-cloudformation-cli-create"></a>

Para crear una pila con la AWS CLI guardada en un archivo llamado `ecs-tutorial-template.yaml`, ejecute el siguiente comando.

```

 La plantilla utilizada en este tutorial crea un servicio de Amazon ECS con dos tareas que se ejecutan en Fargate. Cada una de las tareas ejecuta una aplicación de Amazon ECS de ejemplo. La plantilla también crea un equilibrador de carga de aplicación que distribuye el tráfico de la aplicación y una política de escalado automático de la aplicación que escala la aplicación en función del uso de la CPU. La plantilla también crea los recursos de red necesarios para implementar la aplicación, los recursos de registro para los registros de contenedores y un rol de IAM de ejecución de tareas de Amazon ECS. Para obtener más información sobre el rol de ejecución de tareas, consulte [Rol de IAM de ejecución de tareas de Amazon ECS](task_execution_IAM_role.md). Para obtener más información sobre el escalado automático, consulte [Escalado automático de su servicio de Amazon ECS](service-auto-scaling.md).

Tras crear un archivo de plantilla, utilice el siguiente comando para crear una pila. El indicador `--capabilities` es obligatorio para crear un rol de ejecución de tareas de Amazon ECS tal y como se especifica en la plantilla. También puede especificar el indicador `--parameters` para personalizar los parámetros de la plantilla.

```
aws cloudformation create-stack \
      --stack-name ecs-tutorial-stack \
      --template-body file://ecs-tutorial-template.yaml \
      --region aws-region \
      --capabilities CAPABILITY_NAMED_IAM
```

Después de ejecutar el comando `create-stack`, puede usar `describe-stacks` para comprobar el estado de la creación de la pila.

```
aws cloudformation describe-stacks \
      --stack-name ecs-tutorial-stack \
      --region aws-region
```

## Paso 2: Verificación de la creación de recursos de Amazon ECS
<a name="ecs-cloudformation-cli-verify"></a>

Para asegurarse de que los recursos de Amazon ECS se creen correctamente, siga estos pasos.

1. Ejecute el siguiente comando para que se muestren todas las definiciones de tarea en una Región de AWS.

   ```
   aws ecs list-task-definitions
   ```

   El comando devuelve una lista de nombres de recurso de Amazon (ARN) de definiciones de tareas. El ARN de la definición de tarea que creó con la plantilla se mostrará en el siguiente formato.

   ```
   {
       "taskDefinitionArns": [
        .....
           "arn:aws:ecs:aws-region:111122223333:task-definition/ecs-tutorial-stack-task:1",
        .....   
       ]
   }
   ```

1. Ejecute el siguiente comando para que se enumeren todos los clústeres en una Región de AWS.

   ```
   aws ecs list-clusters
   ```

   El comando devuelve una lista de ARN de clústeres. El ARN del clúster que creó con la plantilla se mostrará en el siguiente formato.

   ```
   {
       "clusterArns": [
           .....
           "arn:aws:ecs:aws-region:111122223333:cluster/ecs-tutorial-stack-cluster",
           .....
       ]
   }
   ```

1. Ejecute el siguiente comando para enumerar todos los servicios que se ejecutan en el clúster `ecs-tutorial-stack-cluster`.

   ```
   aws ecs list-services \
         --cluster ecs-tutorial-stack-cluster
   ```

   El comando devuelve una lista de ARN de servicios. El ARN del servicio que creó con la plantilla se mostrará en el siguiente formato.

   ```
   {
       "serviceArns": [
           "arn:aws:ecs:aws-region:111122223333:service/ecs-tutorial-stack-cluster/ecs-tutorial-stack-service"
       ]
   }
   ```

También puede obtener el nombre de DNS del equilibrador de carga de aplicación que se creó y usarlo para verificar la creación de los recursos. Para obtener el nombre de DNS, ejecute el siguiente comando:

 Ejecute el siguiente comando para recuperar los resultados de la pila creada. 

```
aws cloudformation describe-stacks \
  --stack-name ecs-tutorial-stack \
  --region aws-region \
  --query 'Stacks[0].Outputs[?OutputKey==`LoadBalancerURL`].OutputValue' \
  --output  text
```

Salida:

```
http://ecs-tutorial-stack-alb-0123456789.aws-region.elb.amazonaws.com
```

Pegue el nombre de DNS en un navegador web para ver una página web que muestre un ejemplo de la aplicación de Amazon ECS.

## Paso 3: Limpieza
<a name="ecs-cloudformation-cli-cleanup"></a>

Para limpiar los recursos que ha creado, ejecute el siguiente comando.

```
aws cloudformation delete-stack \
      --stack-name ecs-stack
```

El comando `delete-stack` inicia la eliminación de la pila CloudFormation que se creó en este tutorial y, por tanto, elimina todos los recursos de la pila. Para verificar la eliminación, puede repetir el procedimiento en [Paso 2: Verificación de la creación de recursos de Amazon ECS](#ecs-cloudformation-cli-verify). La lista de ARN de los resultados ya no incluirá una definición de tarea denominada `ecs-tutorial-stack-task` ni un clúster denominado `ecs-tutorial-stack-cluster`. La llamada `list-services` fallará.

# Plantillas de CloudFormation de ejemplo para Amazon ECS
<a name="working-with-templates"></a>

Puede crear clústeres, definiciones de tareas y servicios de Amazon ECS mediante CloudFormation. Los siguientes temas incluyen plantillas que demuestran cómo crear recursos con diferentes configuraciones. Puede crear estos recursos con estas plantillas mediante la consola de CloudFormation o la AWS CLI.

 Las plantillas de CloudFormation son archivos de texto con formato JSON o YAML que describen los recursos que desea aprovisionar en sus pilas de CloudFormation. Si no está familiarizado con los formatos JSON o YAML, o ambos, puede usar AWS Infrastructure Composer para comenzar a usar las plantillas de CloudFormation. Para obtener más información, consulte [Creación visual de plantillas con Infrastructure Composer](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/infrastructure-composer-for-cloudformation.html) en la *Guía del usuario de AWS CloudFormation*.

Los siguientes temas enumeran plantillas de ejemplo para definiciones de tareas, clústeres y servicios de Amazon ECS.

**Topics**
+ [Definiciones de tareas](#cfn-task-definition)
+ [Proveedores de capacidad](#create-capacity-providers)
+ [Clústeres](#create-clusters)
+ [Services](#create-service)
+ [Roles de IAM para Amazon ECS](#ecs-cloudformation-iam-roles)

## Definiciones de tareas
<a name="cfn-task-definition"></a>

Una definición de tarea es un esquema para su aplicación que describe los parámetros y uno o más contenedores que forman su aplicación. A continuación se muestran plantillas de CloudFormation de ejemplo para las definiciones de tareas de Amazon ECS. Para obtener más información sobre definiciones de tareas de Amazon ECS, consulte [Definiciones de tareas de Amazon ECS](task_definitions.md).

## Proveedores de capacidad
<a name="create-capacity-providers"></a>

Los proveedores de capacidad están asociados a un clúster de Amazon ECS y se utilizan para administrar capacidad de computación para las cargas de trabajo.

### Creación de un proveedor de capacidad para instancias administradas de Amazon ECS
<a name="create-managed-instances-capacity-provider"></a>

 De manera predeterminada, Amazon ECS proporciona un proveedor de capacidad que selecciona automáticamente los tipos de instancias de uso general con los costos más optimizados. Sin embargo, puede crear proveedores de capacidad personalizados para especificar los requisitos de las instancias, como los tipos de instancias, los fabricantes de CPU, los tipos de aceleradores y otros requisitos. Puede utilizar la plantilla siguiente para crear un proveedor de capacidad para instancias administradas de Amazon ECS que cumpla con los requisitos de memoria y CPU especificados.

## Services
<a name="create-service"></a>

Puede utilizar un servicio de Amazon ECS para ejecutar y mantener un número determinado de instancias de una definición de tarea de manera simultánea en un clúster de Amazon ECS. Si una de las tareas falla o se detiene, el programador de servicios de Amazon ECS lanza otra instancia de su definición de tarea para sustituirla. Esto ayuda a mantener el número deseado de tareas en el servicio. Las siguientes plantillas se pueden utilizar para implementar servicios. Para obtener más información sobre los servicios de Amazon ECS, consulte [Servicios de Amazon ECS](ecs_services.md).

### Implementación de una aplicación web con equilibrio de carga
<a name="simple-service"></a>

 La siguiente plantilla crea un servicio de Amazon ECS con dos tareas que se ejecutan en Fargate. Cada una de las tareas tiene un contenedor NGINX. La plantilla también crea un equilibrador de carga de aplicación que distribuye el tráfico de la aplicación y una política de escalado automático de la aplicación que escala la aplicación en función del uso de la CPU. La plantilla también crea los recursos de red necesarios para implementar la aplicación, los recursos de registro para los registros de contenedores y un rol de IAM de ejecución de tareas de Amazon ECS. Para obtener más información sobre el rol de ejecución de tareas, consulte [Rol de IAM de ejecución de tareas de Amazon ECS](task_execution_IAM_role.md). Para obtener más información sobre el escalado automático, consulte [Escalado automático de su servicio de Amazon ECS](service-auto-scaling.md).

### Implementación de un servicio con ECS Exec activado
<a name="service-ecs-exec"></a>

Puede usar la siguiente plantilla para implementar un servicio con ECS Exec activado. El servicio se ejecuta en un clúster con una clave de KMS para cifrar las sesiones de ECS Exec y una configuración de registro para redirigir los registros de las sesiones de comandos de ejecución a un bucket de Amazon S3. Para obtener más información, consulte [Supervisión de los contenedores de Amazon ECS con ECS Exec](ecs-exec.md).

### Implementación de un servicio que utilice Amazon VPC Lattice
<a name="service-vpc-lattice"></a>

Puede usar la siguiente plantilla para empezar a crear un servicio de Amazon ECS con VPC Lattice. Es posible que tenga que completar los siguientes pasos adicionales para configurar VPC Lattice: 
+ Actualice las reglas de entrada de su grupo de seguridad para VPC Lattice a fin de permitir el prefijo de la regla de entrada `vpc-lattice` y permitir el tráfico en el puerto 80.
+ Asocie la VPC del servicio a una red de servicios de VPC Lattice.
+ Configure una zona alojada pública o privada con Amazon Route 53.
+ Configure los oyentes y sus reglas en un servicio de VPC Lattice.
+ Verifique las configuraciones de comprobación de estado del grupo de destino.

Para obtener más información acerca del uso de VPC Lattice con Amazon VPC, consulte [Uso de Amazon VPC Lattice para conectar, observar y proteger los servicios de Amazon ECS](ecs-vpc-lattice.md).

## Roles de IAM para Amazon ECS
<a name="ecs-cloudformation-iam-roles"></a>

Puede utilizar plantillas de CloudFormation para crear roles de IAM y utilizarlos con Amazon ECS. Para obtener más información sobre los roles de IAM para Amazon ECS, consulte [Roles de IAM para Amazon ECS](security-ecs-iam-role-overview.md).

### Rol de ejecución de tareas de Amazon ECS
<a name="ecs-cloudformation-iam-roles-task-execution"></a>

El rol de ejecución de tareas concede al agente de contenedor de Amazon ECS y al agente de Fargate permiso para realizar llamadas a la API de AWS en su nombre. El rol es necesario en función de los requisitos de la tarea. Para obtener más información, consulte [Rol de IAM de ejecución de tareas de Amazon ECS](task_execution_IAM_role.md).

La siguiente plantilla se puede utilizar para crear un rol de ejecución de tareas sencillo que utilice la política administrada `AmazonECSTaskExecutionRolePolicy`.
