一、运行docker
该命令执行后是在窗口下运行的，关闭或退出后docker应用会停止运行
-p：设置绑定端口映射，10022对应服务器主机的端口，22docker容器内部使用的端口-v：设置硬盘路径映射，/var/gogs对应服务器主机的本地路径，/datadocker容器内部路径
docker run --name=gogs -p 10022:22 -p 4040:3000 -v /var/gogs:/data gogs/gogs
想要在后台自动运行，需要先退出再重新执行以下命令运行
docker start gogs
二、拉取的镜像存放位置
通过docker pull <image_name>拉取的镜像存放位置可以通过docker inspect <image_id_or_name>查询，<image_id_or_name>可以通过docker images查询。
1、查询所有拉取的镜像
root@VM-8-14-ubuntu:~/serverRoom/php-tcp-sever# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
gogs/gogs latest 21845f737745 4 days ago 96.3MB
emqx/emqx latest f9a9d20bd75c 2 months ago 476MB
2、查询所有安装的镜像
root@VM-8-14-ubuntu:~/serverRoom/php-tcp-sever# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
d023f87b6eb4 gogs/gogs "/app/gogs/docker/st…" 3 hours ago Up About an hour (healthy) 0.0.0.0:10022->22/tcp, :::10022->22/tcp, 0.0.0.0:4040->3000/tcp, :::4040->3000/tcp gogs
3、查询docker应用的所有信息
根据安装了的镜像CONTAINER ID或者查询所有信息
GraphDriver.Data.MergedDir就是镜像源码的存放位置。
