docker-compose

docker-compose -v

启动多个容器

docker-compose up -d

停止

docker-compose stop

查看

docker-compose ps
docker-compose ps -a

退出容器

1. 不要用ctrl+c，ctrl+c是让docker容器停止了。

2. 用如下快捷键：先按：ctrl+p;再按：ctrl+q。

dockerfile VOLUME

VOLUME 指令创建的挂载点，无法指定主机上对应的目录，对应目录是自动生成的，用命令查看docker inspect。

VOLUME ["/var/jetty/pft/web/logs"]

docker inspect

通过docker inspect 查看通过该dockerfile创建的镜像生成的容器,通过Mounts属性看挂载点的信息。

"Mounts": [          
            {
                "Type": "volume",
                "Name": "0314887f053cfa6fa7ab78880493135fb91ce6c79644b37651b15b168bed387c",
