    // for example exposes "web.host" and "web.tcp.80" system properties for service named `web` with exposed port `80`
    dockerCompose.exposeAsSystemProperties(test)
    // get information about container of service `web` (declared in docker-compose.yml)
    def webInfo = dockerCompose.servicesInfos.web
    // pass host and exposed TCP port 80 as custom-named Java System properties
