AWS::S3::Bucket

The AWS::S3::Bucket resource creates an Amazon S3 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.

To declare this entity in your AWS CloudFormation template, use the following syntax:

Properties

AccelerateConfiguration

Configures the transfer acceleration state for an Amazon S3 bucket. For more information, see Amazon S3 Transfer Acceleration in the Amazon Simple Storage Service Developer Guide.

Required: No

Type: AccelerateConfiguration

Update requires: No interruption

AccessControl

A canned access control list (ACL) that grants predefined permissions to the bucket. For more information about canned ACLs, see Canned ACL in the Amazon Simple Storage Service Developer Guide.

Required: No

Type: String

Update requires: No interruption

AnalyticsConfigurations

Specifies the configuration and any analyses for the analytics filter of an Amazon S3 bucket.

For more information, see GET Bucket analytics in the Amazon Simple Storage Service API Reference.

Required: No

Type: List of AnalyticsConfiguration

Update requires: No interruption

BucketEncryption

Specifies default encryption for a bucket using server-side encryption with Amazon S3-managed keys (SSE-S3) or AWS KMS-managed keys (SSE-KMS) bucket. For information about the Amazon S3 default encryption feature, see Amazon S3 Default Encryption for S3 Buckets in the Amazon Simple Storage Service Developer Guide.

Required: No

Type: BucketEncryption

Update requires: No interruption

BucketName

A name for the bucket. If you don't specify a name, AWS CloudFormation generates a unique ID and uses that ID for the bucket name. For more information, see Name Type. The bucket name must contain only lowercase letters, numbers, periods (.), and dashes (-).

Important

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.

Required: No

Type: String

Update requires: Replacement

CorsConfiguration

Describes the cross-origin access configuration for objects in an Amazon S3 bucket. For more information, see Enabling Cross-Origin Resource Sharing in the Amazon Simple Storage Service Developer Guide.

Required: No

Type: CorsConfiguration

Update requires: No interruption

InventoryConfigurations

Specifies the inventory configuration for an Amazon S3 bucket. For more information, see GET Bucket inventory in the Amazon Simple Storage Service API Reference.

Required: No

Type: List of InventoryConfiguration

Update requires: No interruption

LifecycleConfiguration

Specifies the lifecycle configuration for objects in an Amazon S3 bucket. For more information, see Object Lifecycle Management in the Amazon Simple Storage Service Developer Guide.

Required: No

Type: LifecycleConfiguration

Update requires: No interruption

LoggingConfiguration

Settings that define where logs are stored.

Required: No

Type: LoggingConfiguration

Update requires: No interruption

MetricsConfigurations

Specifies a metrics configuration for the CloudWatch request metrics (specified by the metrics configuration ID) from an Amazon S3 bucket. If you're updating an existing metrics configuration, note that this is a full replacement of the existing metrics configuration. If you don't include the elements you want to keep, they are erased. For more information, see PUT Bucket metrics in the Amazon Simple Storage Service API Reference.

Required: No

Type: List of MetricsConfiguration

Update requires: No interruption

NotificationConfiguration

Configuration that defines how Amazon S3 handles bucket notifications.

Required: No

Type: NotificationConfiguration

Update requires: No interruption

PublicAccessBlockConfiguration

Configuration that defines how Amazon S3 handles public access.

Required: No

Type: PublicAccessBlockConfiguration

Update requires: No interruption

ReplicationConfiguration

Configuration for replicating objects in an S3 bucket. To enable replication, you must also enable versioning by using the VersioningConfiguration property.

Amazon S3 can store replicated objects in only one destination bucket. The destination bucket must already exist and be in a different AWS Region than your source bucket.

Required: No

Type: ReplicationConfiguration

Update requires: No interruption

Tags

An arbitrary set of tags (key-value pairs) for this S3 bucket.

Important

We recommend limiting the number of tags to seven. Applying more than seven tags prevents the AWS CLI and the AWS CloudFormation console and API actions from listing the tags for the bucket.

Required: No

Type: List of Tag

Update requires: No interruption

VersioningConfiguration

Enables multiple versions of all objects in this bucket. You might enable versioning to prevent objects from being deleted or overwritten by mistake or to archive objects so that you can retrieve previous versions of them.

Required: No

Type: VersioningConfiguration

Update requires: No interruption

WebsiteConfiguration

Information used to configure the bucket as a static website. For more information, see Hosting Websites on Amazon S3.

Required: No

Type: WebsiteConfiguration

Update requires: No interruption

Return Values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the resource name.

Example: mystack-mybucket-kdwwxmddtr2g

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.

Arn

Returns the Amazon Resource Name (ARN) of the specified bucket.

Example: arn:aws:s3:::mybucket

DomainName

Returns the IPv4 DNS name of the specified bucket.

Example: mystack-mybucket-kdwwxmddtr2g.s3.amazonaws.com

DualStackDomainName

Returns the IPv6 DNS name of the specified bucket.

Example: mystack-mybucket-kdwwxmddtr2g.s3.dualstack.us-east-2.amazonaws.com

For more information about dual-stack endpoints, see Using Amazon S3 Dual-Stack Endpoints.

RegionalDomainName

Returns the regional domain name of the specified bucket.

Example: mystack-mybucket-kdwwxmddtr2g.s3.us-east-2.amazonaws.com

WebsiteURL

Returns the Amazon S3 website endpoint for the specified bucket.

Example (IPv4): http://mystack-mybucket-kdwwxmddtr2g.s3-website-us-east-2.amazonaws.com/

Example (IPv6): http://mystack-mybucket-kdwwxmddtr2g.s3.dualstack.us-east-2.amazonaws.com/

Examples

Associate a Replication Configuration IAM Role with an S3 Bucket

The following example creates an S3 bucket and grants it permission to write to a replication bucket by using an AWS Identity and Access Management (IAM) role. To avoid a circular dependency, the role's policy is declared as a separate resource. The bucket depends on the WorkItemBucketBackupRole role. If the policy is included in the role, the role also depends on the bucket.

Configure a Static Website with a Routing Rule

In this example, AWS::S3::Bucket's Fn::GetAtt values are used to provide outputs. If an HTTP 404 error occurs, the routing rule redirects requests to an EC2 instance and inserts the object key prefix report-404/ in the redirect. For example, if you request a page called ExamplePage.html and it results in an HTTP 404 error, the request is routed to a page called report-404/ExamplePage.html on the specified instance. For all other HTTP error codes, error.html is returned.

This example also specifies a metrics configuration called EntireBucket that enables CloudWatch request metrics at the bucket level.
