AWS::S3::Bucket - AWS CloudFormation

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.

Syntax

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 S3 User Guide.

Required: No

Type: AccelerateConfiguration

Update requires: No interruption

AccessControl
Important

This is a legacy property, and it is not recommended for most use cases. A majority of modern use cases in Amazon S3 no longer require the use of ACLs, and we recommend that you keep ACLs disabled. For more information, see Controlling object ownership in the Amazon S3 User Guide.

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 S3 User Guide.

S3 buckets are created with ACLs disabled by default. Therefore, unless you explicitly set the AWS::S3::OwnershipControls property to enable ACLs, your resource will fail to deploy with any value other than Private. Use cases requiring ACLs are uncommon.

The majority of access control configurations can be successfully and more easily achieved with bucket policies. For more information, see AWS::S3::BucketPolicy. For examples of common policy configurations, including S3 Server Access Logs buckets and more, see Bucket policy examples in the Amazon S3 User Guide.

Examples

Create an S3 bucket

The following example creates an S3 bucket with a Retain deletion policy.

JSON

{ "Resources": { "S3Bucket": { "Type": "AWS::S3::Bucket", "DeletionPolicy": "Retain", "Properties": { "BucketName": "DOC-EXAMPLE-BUCKET" } } } }

YAML

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.

JSON

{ "Resources": { "RecordServiceS3Bucket": { "Type": "AWS::S3::Bucket", "DeletionPolicy": "Retain", "Properties": { "ReplicationConfiguration": { "Role": { "Fn::GetAtt": [ "WorkItemBucketBackupRole", "Arn" ] }, "Rules": [ { "Destination": { "Bucket": { "Fn::Join": [ "", [ "arn:aws:s3:::", { "Fn::Join": [ "-", [ { "Ref": "AWS::Region" }, { "Ref": "AWS::StackName" }, "replicationbucket" ] ] } ] ] }, "StorageClass": "STANDARD" }, "Id": "Backup", "Prefix": "", "Status": "Enabled" } ] }, "VersioningConfiguration": { "Status": "Enabled" } } }, "WorkItemBucketBackupRole": { "Type": "AWS::IAM::Role", "Properties": { "AssumeRolePolicyDocument": { "Statement": [ { "Action": [ "sts:AssumeRole" ], "Effect": "Allow", "Principal": { "Service": [ "s3.amazonaws.com" ] } } ] } } }, "BucketBackupPolicy": { "Type": "AWS::IAM::Policy", "Properties": { "PolicyDocument": { "Statement": [ { "Action": [ "s3:GetReplicationConfiguration", "s3:ListBucket" ], "Effect": "Allow", "Resource": [ { "Fn::Join": [ "", [ "arn:aws:s3:::", { "Ref": "RecordServiceS3Bucket" } ] ] } ] }, { "Action": [ "s3:GetObjectVersion", "s3:GetObjectVersionAcl" ], "Effect": "Allow", "Resource": [ { "Fn::Join": [ "", [ "arn:aws:s3:::", { "Ref": "RecordServiceS3Bucket" }, "/*" ] ] } ] }, { "Action": [ "s3:ReplicateObject", "s3:ReplicateDelete" ], "Effect": "Allow", "Resource": [ { "Fn::Join": [ "", [ "arn:aws:s3:::", { "Fn::Join": [ "-", [ { "Ref": "AWS::Region" }, { "Ref": "AWS::StackName" }, "replicationbucket" ] ] }, "/*" ] ] } ] } ] }, "PolicyName": "BucketBackupPolicy", "Roles": [ { "Ref": "WorkItemBucketBackupRole" } ] } } } }

Granting public access to S3 buckets

When you create a new bucket, all Block Public Access settings are automatically enabled. We recommend that you keep all Block Public Access settings enabled. If you require some level of public access to your buckets, you can disable Block Public Access settings. The following example shows creating a bucket called my-bucket and then disabling Block Public Access. A public bucket policy is then added to the bucket.

Note

The following example assumes the BlockPublicPolicy and RestrictPublicBuckets Block Public Access settings have been disabled at the account level.

JSON

{ "Resources": { "MyBucket": { "Type": "AWS::S3::Bucket", "Properties": { "BucketName": "my-bucket", "PublicAccessBlockConfiguration": { "BlockPublicAcls": false, "BlockPublicPolicy": false, "IgnorePublicAcls": false, "RestrictPublicBuckets": false } } }, "MyBucketPolicy": { "Type": "AWS::S3::BucketPolicy", "Properties": { "Bucket": { "Ref": "MyBucket" }, "PolicyDocument": { "Version": "2012-10-17", "Statement": [ { "Effect": "Allow", "Principal": "*", "Action": "s3:GetObject", "Resource": { "Fn::Join": [ "", [ "arn:aws:s3:::", { "Ref": "MyBucket" }, "/*" ] ] } } ] } } } } }

YAML

Enabling ACLs

By default, S3 Object Ownership is set to BucketOwnerEnforced and ACLs are disabled. A majority of modern use cases in S3 no longer require the use of ACLs, and we recommend that you keep ACLs disabled. With ACLs disabled, you can control access to all objects in your bucket, regardless of who uploaded the objects to your bucket. If your specific use case requires enabling ACLs, you can set S3 Object Ownership to BucketOwnerPreferred or ObjectWriter. For more information, see Controlling ownership of objects and disabling ACLs in the Amazon S3 User Guide.

The following example shows Object Ownership set to BucketOwnerPreferred.

JSON

{ "Resources": { "MyBucket": { "Type": "AWS::S3::Bucket", "Properties": { "BucketName": "my-bucket", "OwnershipControls": { "Rules": [ { "ObjectOwnership": "BucketOwnerPreferred" } ] }, "AccessControl": "AwsExecRead" } } } }

YAML

Resources: MyBucket: Type: 'AWS::S3::Bucket' Properties: BucketName: my-bucket OwnershipControls: Rules: - ObjectOwnership: BucketOwnerPreferred AccessControl: AwsExecRead

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.

JSON
