# AWS::CloudFront::ContinuousDeploymentPolicy
<a name="aws-resource-cloudfront-continuousdeploymentpolicy"></a>

Creates a continuous deployment policy that routes a subset of production traffic from a primary distribution to a staging distribution.

After you create and update a staging distribution, you can use a continuous deployment policy to incrementally move traffic to the staging distribution. This enables you to test changes to a distribution's configuration before moving all of your production traffic to the new configuration.

For more information, see [Using CloudFront continuous deployment to safely test CDN configuration changes](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/continuous-deployment.html) in the *Amazon CloudFront Developer Guide*.

## Return values
<a name="aws-resource-cloudfront-continuousdeploymentpolicy-return-values"></a>

### Ref
<a name="aws-resource-cloudfront-continuousdeploymentpolicy-return-values-ref"></a>

When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the unique identifier for the continuous deployment policy.

For more information about using the `Ref` function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html).

### Fn::GetAtt
<a name="aws-resource-cloudfront-continuousdeploymentpolicy-return-values-fn--getatt"></a>

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 [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-getatt.html).

#### 
<a name="aws-resource-cloudfront-continuousdeploymentpolicy-return-values-fn--getatt-fn--getatt"></a>

`Id`  <a name="Id-fn::getatt"></a>
The identifier of the cotinuous deployment policy.

`LastModifiedTime`  <a name="LastModifiedTime-fn::getatt"></a>
The date and time when the continuous deployment policy was last modified.
