def setup_config():
    rails_api_port = find_available_port()
    controller_port = find_available_port()
    controller_external_port = find_available_port()
    websocket_port = find_available_port()
    websocket_external_port = find_available_port()
    workbench1_port = find_available_port()
    workbench1_external_port = find_available_port()
