问题 Is there a way to define a Docker Compose service such that it is only brought up when you explicitly request it? That is to say: docker-compose up would not start it, but docker-compose up optional_service would. 回答1: One way to achieve that is to define your optional service in a different compose file. Then to start the optional service, run: $ docker-compose -f docker-compose.yml -f optional-service.yaml up For example, if I have a docker-compose.yml file that looks like: version: '2.1'
