Ignoring unsupported options: links

为什么不支持链接？

Answer 1

Links are not required to enable services to communicate - by default, any service can reach any other service at that service’s name. (See also, the Links topic in Networking in Compose.)

因此，该选项是带有(版本3)撰写文件的 ignored when deploying a stack in swarm mode。

$ docker stack deploy --compose-file docker-compose.yml vossibility
