一、环境准备

以我本地为例【Jenkins：192.168.132.52 Docker：192.168.10.143】

1、一台运行Jenkins服务的服务器，需安装插件：git plugin、Git Parameter Plug-In、GitLab Plugin、Publish Over SSH、SSH Slaves plugin

2、一台或若干Docker宿主机服务器

3、一台提供Git服务的服务器（直接使用github服务）

二、搭建Docker宿主机

（1）、安装并启动docker

#sudo yum install docker
#sudo service docker start

（2）、创建docker账户、密码

#useradd docker -d /home/docker -s /bin/bash
#echo "docker:docker" | chpasswd

（3）、将docker创建到指定账户下

#mkdir /data/dockerfiles/scripts -p

（4）、将脚本deploy.sh复制到/data/dockerfiles/scripts下

#vi /data/dockerfiles/scripts/deploy.sh
#chmod +x /data/dockerfiles/scripts/deploy.sh
#chown docker:docker /data/dockerfiles -R
#ls -al /data/dockerfiles/

delpoy.sh 源码
