[*]环境：Centos7
[*]ip:172.16.1.10
[*]Docker version 1.13.1
运行一个容器、“-i”捕获标准输入输出、“-t分配一个控制台”
# docker run -i -t centos /bin/bash# lsbindevetchomeliblib64lost+foundmediamntoptprocrootrunsbinsrvsystmpusrvar#创建镜像
-a 作者信息,-m 提交信息,-p 提交时暂停容器运行,如果提交成功会返回一个id数字串。# docker commit -m "aaa" -a "chao" 86a46aa13531sha256:6efd478542f1a99b20796c9372c2976b87344263a051dbf39fd385ea4dbb8873查看镜像

docker save 命令转出，docker load 命令转入。转出chao镜像为CHAO
# docker save -o CHAO.tar chao:latest# ls123anaconda-ks.cfgCHAO.tarinitial-setup-ks.cfg删除镜像
