如何重新启动容器而不重新创建容器？我只是不想丢失数据库中的数据。

$ docker-compose stop
$ docker-compose start
Starting redis     ... error
Starting rabbitmq  ... error
Starting mysql     ... error
Starting php-fpm   ... error

您的情况可能与将在18.03版本中修复的错误有关。这里提出了一些解决方法：

• https://github.com/docker/for-linux/issues/211
• https://github.com/moby/moby/issues/36145

docker-compose up 构建，（重新）创建，启动并附加到服务的容器。

由于您的服务器images已构建并且containers服务已启动，因此您可以使用

• docker-compose stop 和
• docker-compose start

开始/停止您的服务。这与以下不同docker-compose down：

停止容器并删除由创建的容器，网络，卷和映像up。

关于删除容器后丢失数据的危险，请阅读有关持久性存储以及如何使用卷的信息。
