AWS::Config::DeliveryChannel

Specifies a delivery channel object to deliver configuration information to an Amazon S3 bucket and Amazon SNS topic.

Before you can create a delivery channel, you must create a configuration recorder.

You can use this action to change the Amazon S3 bucket or an Amazon SNS topic of the existing delivery channel. To change the Amazon S3 bucket or an Amazon SNS topic, call this action and specify the changed values for the S3 bucket and the SNS topic. If you specify a different value for either the S3 bucket or the SNS topic, this action will keep the existing value for the parameter that is not changed.

Note

You can have only one delivery channel per region in your account.

When you create the delivery channel, you can specify; how often AWS Config delivers configuration snapshots to your Amazon S3 bucket (for example, 24 hours), the S3 bucket to which AWS Config sends configuration snapshots and configuration history files, and the Amazon SNS topic to which AWS Config sends notifications about configuration changes, such as updated resources, AWS Config rule evaluations, and when AWS Config delivers the configuration snapshot to your S3 bucket. For more information, see Deliver Configuration Items in the AWS Config Developer Guide.

Note

To enable AWS Config, you must create a configuration recorder and a delivery channel. If you want to create the resources separately, you must create a configuration recorder before you can create a delivery channel. AWS Config uses the configuration recorder to capture configuration changes to your resources. For more information, see AWS::Config::ConfigurationRecorder.

For more information, see Managing the Delivery Channel in the AWS Config Developer Guide.

Type: AWS::Config::DeliveryChannel Properties: ConfigSnapshotDeliveryProperties: ConfigSnapshotDeliveryProperties Name: String S3BucketName: String S3KeyPrefix: String SnsTopicARN: String

Properties

ConfigSnapshotDeliveryProperties

The options for how often AWS Config delivers configuration snapshots to the Amazon S3 bucket.

Required: No

Type: ConfigSnapshotDeliveryProperties

Update requires: No interruption

Name

A name for the delivery channel. If you don't specify a name, AWS CloudFormation generates a unique physical ID and uses that ID for the delivery channel name. For more information, see Name Type.

Updates are not supported. To change the name, you must run two separate updates. In the first update, delete this resource, and then recreate it with a new name in the second update.

S3BucketName

The name of the Amazon S3 bucket to which AWS Config delivers configuration snapshots and configuration history files.

If you specify a bucket that belongs to another AWS account, that bucket must have policies that grant access permissions to AWS Config. For more information, see Permissions for the Amazon S3 Bucket in the AWS Config Developer Guide.

Required: Yes

Type: String

Update requires: No interruption

S3KeyPrefix

The prefix for the specified Amazon S3 bucket.

Required: No

Type: String

Update requires: No interruption

SnsTopicARN

The Amazon Resource Name (ARN) of the Amazon SNS topic to which AWS Config sends notifications about configuration changes.

Required: No

Type: String

Update requires: No interruption

Return Values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the delivery channel name, such as default.

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

Examples

Delivery Channel

The following example creates a delivery channel that sends notifications to the specified Amazon SNS topic. The delivery channel also sends configuration changes and snapshots to the specified S3 bucket.
