Use a volume with Docker Compose The following example shows a single Docker Compose service with a volume: services:frontend:image:node:ltsvolumes:-myapp:/home/node/appvolumes:myapp: Runningdocker compose upfor the first time creates a volume. Docker reuses the same volume when you run the co...
在Docker Compose文件中,可以使用volume配置来定义容器和主机之间的共享卷。volume配置的语法如下: 其中,<volume_name>是你想要创建的卷的名称,<container_path>是容器内部的路径,指定了容器内部的目录将会和主机上的卷进行映射。 例如,你可以在Docker Compose文件中定义一个volume配置如下: 这将会创建一个名为data_vol...

Volume drivers let you store volumes on remote hosts or cloud providers, to encrypt the contents of volumes, or to add other functionality. 卷驱动程序允许您在远程主机或云提供商上存储卷,以加密卷的内容或添加其他功能。 New volumes can have their content pre-populated by a container. ...
