Object storage with bucket-scoped sub-resources — policies, versioning, lifecycle, CORS, ACLs, notifications, object lock, range requests.

REST-XML multi-tenant 73 operations

Quick start

import boto3
s3 = boto3.client("s3", endpoint_url="http://localhost:4566",
                  region_name="us-east-1",
                  aws_access_key_id="test", aws_secret_access_key="test")
s3.create_bucket(Bucket="demo")
s3.put_object(Bucket="demo", Key="hi.txt", Body=b"hello")
print(s3.get_object(Bucket="demo", Key="hi.txt")["Body"].read())

CloudFormation

The CloudFormation engine provisions these resource types via this service:

AWS::S3::Bucket AWS::S3::BucketPolicy

See CloudFormation engine for intrinsic support and lifecycle details.

Known limitations

SSE-KMS encryption keys are stored per object but encryption/decryption is a silent no-op — ciphertext equals plaintext.
Replication configuration accepted; no cross-bucket replication is performed.
Notification configuration accepted; events are only dispatched for SQS/SNS/Lambda targets that MiniStack tracks.
