# 获取 Amazon RDS 的现有 ARN
<a name="USER_Tagging.ARN.Getting"></a>

您可以使用 Amazon Web Services 管理控制台、Amazon Command Line Interface (Amazon CLI) 或 RDS API 来获取 RDS 资源的 ARN。

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

要从 Amazon Web Services 管理控制台中获取一个 ARN，请导航到要获取 ARN 的资源，然后查看该资源的详细信息。

例如，您可以从数据库集群详细信息的**配置**选项卡获取数据库集群的 ARN。

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

要从 Amazon CLI 为特定 RDS 资源获取 ARN，请对该资源使用 `describe` 命令。下表显示了每个 Amazon CLI 命令，以及与命令配合使用以获取 ARN 的 ARN 属性。


****  

| Amazon CLI command | ARN 属性 | 
| --- | --- | 
|  [describe-event-subscriptions](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-event-subscriptions.html)  | EventSubscriptionArn | 
|  [describe-certificates](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-certificates.html) | CertificateArn | 
|  [describe-db-parameter-groups](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-db-parameter-groups.html) | DBParameterGroupArn | 
|  [describe-db-cluster-parameter-groups](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-db-cluster-parameter-groups.html) | DBClusterParameterGroupArn | 
|  [describe-db-instances](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-db-instances.html) | DBInstanceArn | 
|  [describe-db-security-groups](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-db-security-groups.html) | DBSecurityGroupArn | 
|  [describe-db-snapshots](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-db-snapshots.html) | DBSnapshotArn | 
|  [describe-events](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-events.html) | SourceArn | 
|  [describe-reserved-db-instances](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-reserved-db-instances.html) | ReservedDBInstanceArn | 
|  [describe-db-subnet-groups](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-db-subnet-groups.html) | DBSubnetGroupArn | 
|  [describe-db-clusters](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-db-clusters.html) | DBClusterArn | 
|  [describe-db-cluster-snapshots](https://docs.amazonaws.cn/cli/latest/reference/rds/describe-db-cluster-snapshots.html) | DBClusterSnapshotArn | 

例如，以下 Amazon CLI 命令获取数据库实例的 ARN。

**Example**  
对于 Linux、macOS 或 Unix：  

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

```
aws rds describe-db-instances ^
--db-instance-identifier {{DBInstanceIdentifier}} ^
--region {{us-west-2}} ^
--query "*[].{DBInstanceIdentifier:DBInstanceIdentifier,DBInstanceArn:DBInstanceArn}"
```
该命令的输出如下所示：  

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

## RDS API

要为特定 RDS 资源获取 ARN，您可以调用以下 RDS API 操作并使用如下所示的 ARN 属性。


****

|  [DescribeCertificates](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_DescribeCertificates.html) | CertificateArn | 
|  [DescribeDBParameterGroups](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_DescribeDBParameterGroups.html) | DBParameterGroupArn | 
|  [DescribeDBClusterParameterGroups](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_DescribeDBClusterParameterGroups.html) | DBClusterParameterGroupArn |

|  [DescribeEvents](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_DescribeEvents.html) | SourceArn | 
|  [DescribeReservedDBInstances](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_DescribeReservedDBInstances.html) | ReservedDBInstanceArn | 
|  [DescribeDBSubnetGroups](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_DescribeDBSubnetGroups.html) | DBSubnetGroupArn | 
|  [DescribeDBClusters](https://docs.amazonaws.cn/AmazonRDS/latest/APIReference/API_DescribeDBClusters.html) | DBClusterArn |
