Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the location resource Amazon Resource Name (ARN). For example:

arn:aws:datasync:us-east-2:111222333444:location/loc-07db7abfc326c50s3

For more information about using the Ref function, see Ref.

Fn::GetAtt

The Fn::GetAtt intrinsic function returns a value for a specified attribute of this type. The following are the available attributes and sample return values.

For more information about using the Fn::GetAtt intrinsic function, see Fn::GetAtt.

LocationArn

The Amazon Resource Name (ARN) of the specified Amazon S3 location.

LocationUri

The URI of the specified Amazon S3 location.

Examples

Create an Amazon S3 location for DataSync

The following example specifies an S3 location for DataSync. In this example, the S3 location uses the bucket specified by the Amazon Resource Name (ARN) arn:aws:s3:::MyBucket. The access role is specified by the ARN arn:aws:iam::111222333444:role/MyBucketAccessRole. The example uses the S3 Standard storage class and refers to the subdirectory /MyFolder.

Amazon Security Token Service (Amazon STS) must be activated in your account and Region for DataSync to assume the IAM role. For more information about temporary security credentials, see Temporary security credentials in IAM in the IAM User Guide .
