S3 Express Mode

AIStor supports running in S3 Express Mode. This mode enables directory bucket behavior for optimized heirarchial storage structures. While object store prefixes generally support organized storage, S3 Express Mode implements the specific directory bucket behaviors documented by AWS.

S3Express mode disables most API operations outside of simple bucket and object PUT, GET, DELETE, and LIST operations. All other API operations return not supported errors, including operations for versioning, locking, and replication.

Add the --api parameter to the MINIO_OPTS parameter list in /etc/default/minio:

# /etc/default/minio
MINIO_OPTS="--api='S3Express' ..."

Append the parameter to the existing list of options passed to the minio process.
