将现有的系统打包成Docker镜像文件
tar --numeric-owner --exclude=/proc --exclude=/sys --exclude=dev --exclude=run --exclude=boot -cvf /home/JosonDisk/centos7-base.tar /
tar --numeric-owner --exclude=/*.rpm \
--exclude=/home/JosonDisk \
--exclude=/usr/share/javadoc \
--exclude=/usr/lib/jvm \
--exclude=/usr/share/dotnet \
--exclude=/root/mySQL5.7 \
--exclude=/srv/pentaho-server-ce \
--exclude=/proc \
--exclude=/sys \
--exclude=dev \
--exclude=run \
--exclude=boot -cvf /home/JosonDisk/centos7-base.tar /
docker import centos7-base.tar centos7
docker run -itd --name JosonCentos centos7:latest /bin/bash
如果你的系统装有Docker 打包后，想使用Docker 那么上面语句会报错
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
首先 docker --version 看 docker 是否 被打包进来了， 然后使用 systemctl status docker 查看具体原因为：
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
那么你需要使用下面语句
docker run -itd --privileged=true --name JosonCentos centos7:latest /usr/sbin/init
docker tag centos7 josonjiang/centos7
docker push josonjiang/centos7:latest
docker pull josonjiang/centos7:latest
