Docker-下调 default_network 错误

我有一个 docker-与一些 php，mysql 等组成开始。几天后，我不能把他们下来，因为一切停止，而不是 mysql。它总是给我以下错误:

ERROR: network docker_default has active endpoints

这是我的码头作品

container_name: mysql
volumes:

更新

看起来 docker rm mysql -f停止了 mysql 容器，但是网络正在运行。

删除了与 docker network disconnect -f docker_default mysql的网络，但我很感兴趣，我是如何进入这种情况。有什么想法？
