AWS::S3::Bucket ReplicationConfiguration - AWS CloudFormation

AWS::S3::Bucket ReplicationConfiguration

A container for replication rules. You can add up to 1,000 rules. The maximum size of a replication configuration is 2 MB.

Syntax

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

JSON

{ "Role" : String, "Rules" : [ ReplicationRule, ... ] }

YAML

Role: String Rules: - ReplicationRule

Properties

Role

The Amazon Resource Name (ARN) of the AWS Identity and Access Management (IAM) role that Amazon S3 assumes when replicating objects. For more information, see How to Set Up Replication in the Amazon S3 User Guide.

Required: Yes

Type: String

Update requires: No interruption

Rules

A container for one or more replication rules. A replication configuration must have at least one rule and can contain a maximum of 1,000 rules.

Required: Yes

Type: List of ReplicationRule

Update requires: No interruption

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.

Enable versioning and replicate objects

The following example enables versioning and two replication rules. The rules copy objects prefixed with either MyPrefix and MyOtherPrefix and stores the copied objects in a bucket named my-replication-bucket.
