泊坞窗撰写文件是无效的，附加属性不允许
这是我的示例docker-compose.yml文件。
version: '2' config-server: image: ccc/config-server restart: always registration-server: image: ccc/registration-server restart: always ports: - 1111:1111 当我使用docker-compose up -d我得到一个错误：
"ERROR: The Compose file './docker-compose.yml' is invalid because: Additional properties are not allowed ('registration-server', 'config-server' were unexpected) You might be seeing this error because you're using the wrong Compose file version. Either specify a version of "2" (or "2.0") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1. For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/
任何人都可以帮我吗？
您错过了一个services关键字，您正确的.yml是：
version: '2' services: config-server: image: ccc/config-server restart: always registration-server: image: ccc/registration-server restart: always ports: - 1111:1111
