我是靠谱客的博主 从容乌龟，最近开发中收集的这篇文章主要介绍Docker images制作，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

docker pull : 从镜像仓库中拉取或者更新指定镜像

Sharing volumes 

容器之间做共享卷有2种方式：
      （1）多个容器的卷使用同一个主机目录，例如：
            ~]# docker run –it --name c1 -v /docker/volumes/v1:/data busybox 
            ~]# docker run –it --name c2 -v /docker/volumes/v1:/data busybox 
      （2）复制使用其它容器的卷，为docker run命令使用--volumes-from选项 ,例如：
           ~]# docker run -it --name bbox1 -v /docker/volumes/v1:/data busybox
           ~]# docker run -it --name bbox2 --volumes-from bbox1 busybox

[root@node2 ~]# cat /appdata/html/index.html
