AWS::S3Express::DirectoryBucket - AWS CloudFormation
SyntaxPropertiesReturn values

AWS::S3Express::DirectoryBucket

The AWS::S3Express::DirectoryBucket resource creates an Amazon S3 directory bucket in the same AWS Region where you create the AWS CloudFormation stack.

To control how AWS CloudFormation handles the bucket when the stack is deleted, you can set a deletion policy for your bucket. You can choose to retain the bucket or to delete the bucket. For more information, see DeletionPolicy attribute.

Important

You can only delete empty buckets. Deletion fails for buckets that have contents.

Permissions

The required permissions for CloudFormation to use are based on the operations that are performed on the stack.

  • Create

    • s3express:CreateBucket

    • s3express:ListAllMyDirectoryBuckets

  • Read

    • s3express:ListAllMyDirectoryBuckets

  • Delete

    • s3express:DeleteBucket

    • s3express:ListAllMyDirectoryBuckets

  • List

    • s3express:ListAllMyDirectoryBuckets

Properties

BucketName

A name for the bucket. The bucket name must contain only lowercase letters, numbers, and hyphens (-). A directory bucket name must be unique in the chosen Availability Zone. The bucket name must also follow the format bucket_base_name--az_id--x-s3 (for example, DOC-EXAMPLE-BUCKET--usw2-az1--x-s3). If you don't specify a name, AWS CloudFormation generates a unique ID and uses that ID for the bucket name. For information about bucket naming restrictions, see Directory bucket naming rules in the Amazon S3 User Guide.

If you specify a name, you can't perform updates that require replacement of this resource. You can perform updates that require no or some interruption. If you need to replace the resource, specify a new name.
