# Obtención de un ARN existente para Amazon RDS
<a name="USER_Tagging.ARN.Getting"></a>

Puede obtener el ARN de un recurso de RDS mediante la Consola de administración de AWS, la AWS Command Line Interface (AWS CLI) o la API de RDS. 

## Consola
<a name="USER_Tagging.ARN.CON"></a>

Para obtener un ARN desde la Consola de administración de AWS, vaya al recurso cuyo ARN desea obtener y consulte los detalles de ese recurso.

Por ejemplo, puede obtener el ARN de un clúster de base de datos desde la pestaña **Configuración** de los detalles del clúster de base de datos.

## AWS CLI
<a name="USER_Tagging.ARN.CLI"></a>

Para obtener el ARN de un recurso concreto de RDS desde la AWS CLI, se utiliza el comando `describe` con dicho recurso. En la siguiente tabla se muestran los distintos comandos de AWS CLI, junto con la propiedad ARN que se utiliza con el comando para obtener un ARN. 


****  

| AWS CLI command | Propiedad ARN | 
| --- | --- | 
|  [describe-event-subscriptions](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-event-subscriptions.html)  | EventSubscriptionArn | 
|  [describe-certificates](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-certificates.html) | CertificateArn | 
|  [describe-db-parameter-groups](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-parameter-groups.html) | DBParameterGroupArn | 
|  [describe-db-clúster-parameter-groups](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-cluster-parameter-groups.html) | DBclústerParameterGroupArn | 
|  [describe-db-instances](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-instances.html) | DBInstanceArn | 
|  [describe-db-security-groups](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-security-groups.html) | DBSecurityGroupArn | 
|  [describe-db-snapshots](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-snapshots.html) | DBSnapshotArn | 
|  [describe-events](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-events.html) | SourceArn | 
|  [describe-reserved-db-instances](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-reserved-db-instances.html) | ReservedDBInstanceArn | 
|  [describe-db-subnet-groups](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-subnet-groups.html) | DBSubnetGroupArn | 
|  [describe-db-clústers](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-clusters.html) | DBclústerArn | 
|  [describe-db-clúster-snapshots](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-cluster-snapshots.html) | DBclústerSnapshotArn | 

Por ejemplo, el siguiente comando de la AWS CLI obtiene el ARN de una instancia de base de datos.

**Example**  
Para Linux, macOS o Unix:  

```
aws rds describe-db-instances \
--db-instance-identifier {{DBInstanceIdentifier}} \
--region {{us-west-2}} \
--query "*[].{DBInstanceIdentifier:DBInstanceIdentifier,DBInstanceArn:DBInstanceArn}"
```
Para Windows:  

```
aws rds describe-db-instances ^
--db-instance-identifier {{DBInstanceIdentifier}} ^
--region {{us-west-2}} ^
--query "*[].{DBInstanceIdentifier:DBInstanceIdentifier,DBInstanceArn:DBInstanceArn}"
```
El resultado de ese comando es como el siguiente:  

```
[
    {
        "DBInstanceArn": "arn:aws:rds:us-west-2:{{account_id}}:db:{{instance_id}}", 
        "DBInstanceIdentifier": "{{instance_id}}"
    }
]
```
