Here are some (minimal) sample settings for development or experimentation:

// ARN - representation of resources based on AWS ARNs.
type ARN struct {
	Partition    string
	Service      string
	Region       string
	ResourceType string
	ResourceID   string
}

// Allows english letters, numbers, '.', '-', '_' and '/'. Starts with a
// letter or digit. At least 1 character long.
var validResourceIDRegex = regexp.MustCompile(`[A-Za-z0-9_/\.-]+$`)

// NewIAMRoleARN - returns an ARN for a role in MinIO.
