如何在不重新创建容器的情况下重新启动容器？我只是不想丢失数据库中的数据。

---------------更新--------------------

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

ERROR: for rabbitmq  Cannot start service rabbitmq: container "3b6c...0aba": already exists

ERROR: for mysql  Cannot start service mysql: container "ff36...1116": already exists

ERROR: for redis  Cannot start service redis: container "e84f...f91": already exists
ERROR: No containers to start

Answer 1

您的案例可能与将在18.03版本中修复的错误有关。这里提出了一些解决方法：

docker-compose up构建，（重新）创建，启动和附加服务的容器。

由于您构建了images并且服务的containers已经开始，您可以使用

docker-compose stop和
docker-compose start

开始/停止您的服务。这与docker-compose down不同，后者：

停止容器并移除由up创建的容器，网络，卷和图像。

关于删除容器时丢失数据的危险，请阅读持久存储以及如何使用卷。

Answer 2

您需要使用docker-compose start代替：

$ docker-compose start --help
Start existing containers.

Usage: start [SERVICE...]

Docker无法启动已存在的服务
