Example:
s3.bucket.create -name <bucket_name>
s3.bucket.create -name <bucket_name> -owner <identity_name>
The -owner flag sets the bucket owner identity. This is important when using
S3 IAM authentication, as non-admin users can only access buckets they own.
If not specified, the bucket will have no owner and will only be accessible
by admin users.
The -owner value should match the identity name configured in your S3 IAM
system (the "name" field in s3.json identities configuration).
