## MinIO configuration YAML

MinIO now supports starting the server arguments and configuration via a YAML configuration file. This YAML configuration describes everything that can be configured in a MinIO setup, such as '--address', '--console-address' and command line arguments for the MinIO server.

     * @param artifacts the collection of artifacts to deploy
