一、先下载个包，然后解压（自己找个目录下载即可）
[root@localhost soft]# wget https://github.com/happyfish100/fastdfs/archive/master.zip

二、进入fastdfs-master/docker/dockerfile_network目录，执行打包命令
[root@localhost soft]# cd fastdfs-master/docker/dockerfile_network [root@localhost dockerfile_network]#
打包（注意，你的宿主机内存至少要2G，不然会报错如下：）我之前只分配给宿主机1G内存，明显不够用。
好，执行命令打包：（注意最后有个点）
[root@localhost dockerfile_network]# docker build -t local/fastdfs:latest .

（额，这是我第二次打包，我第一次打包输出好多内容的，你们自行体会，你们应该能看见 ---> Using cache 利用了缓存）
到这里，镜像就打包好了。后面告诉你怎么玩。
