docker - docker-如何在docker up和up之后保持数据？

Question

我运行此命令来拉图像，服务

docker-compose -f dc-all.yml up

docker-compose -f dc-all.yml down

保留数据的最佳实践是什么？

还是如何保持docker在不重启的情况下运行？例如Windows重启不

您可以像在Docker中一样使用卷。有关所有详细信息，请参见full doc。

但基本上你想要:

services:
  some_service:    
    volumes:
        - $PWD/data:/path/to/data
