To configure Amazon S3 replication in LocalStack, follow these steps:

1. Install and start LocalStack.
2. Create two S3 buckets in LocalStack.
3. Enable versioning on both buckets.
4. Create a replication rule in the source bucket to replicate to the destination bucket.

Here are more detailed steps:

1. Install and start LocalStack
2. Install LocalStack using pip: pip install localstack

3. Start LocalStack using the following command: localstack start

4. Create two S3 buckets in LocalStack

5. Create the source bucket: aws --endpoint-url=http://localhost:4566 s3api create-bucket --bucket=my-source --region=us-east-1

6. Create the destination bucket: aws --endpoint-url=http://localhost:4566 s3api create-bucket --bucket=my-destination --region=us-east-1

7. Enable versioning on both buckets

8. Enable versioning on the source bucket: aws --endpoint-url=http://localhost:4566 s3api put-bucket-versioning --bucket=my-source --versioning-configuration Status=Enabled

9. Enable versioning on the destination bucket: aws --endpoint-url=http://localhost:4566 s3api put-bucket-versioning --bucket=my-destination --versioning-configuration Status=Enabled

10. Create a replication rule in the source bucket to replicate to the destination bucket.

11. Create the replication rule: aws --endpoint-url=http://localhost:4566 s3api put-bucket-replication --bucket=my-source --replication-configuration file://replication.json
12. In the replication.json file, specify the replication configuration. Here's an example configuration:

{
   "Role": "arn:aws:iam::012345678901:role/my-role",
   "Rules": [
       {
           "Destination": {
               "Bucket": "arn:aws:s3:::my-destination"
           },
           "Status": "Enabled",
           "Prefix": "my-prefix/"
       }
   ]
}

In this example, the replication rule specifies that all objects with the prefix my-prefix/ in the source bucket should be replicated to the destination bucket.

Once you've completed these steps, Amazon S3 replication should be configured in LocalStack. You can test the replication by uploading an object with the specified prefix to the source bucket and verifying that it is replicated to the destination bucket.
