通过jenkins平台自动发布程序到dokcer容器
前言：
最近在研究docker持续集成发布，从2015年8月份开始学习docker，两个月的时间学习了docker的基础理论，进行了项目通过Docker容器运行的多次实验。我想通过jenkins构建发布docker容器，试验了很久都没成功，目前完成了一个简单的发布流程，即通过jenkins构建代码，调用shell，更新到目标服务器的容器里。
一、Jenkins安装部署
1，部署java环境。(这里用的是jdk7和tomcat7)
mkdir -p /data/webserver
cd /data/webserver
wget
rpm -ivh jdk-7u55-linux-x64.rpm
wget
tar zxvf apache-tomcat-7.0.53.tar.gz
cat > /etc/profile.d/development.sh <<EOF
export JAVA_HOME=/usr/java/jdk1.7.0_55
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH
export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH
EOF
source /etc/profile.d/development.sh
2，部署jenkins项目
从官网下载jenkins程序包，上传到服务器的程序目录，删除tomcat/webapps目录下的所有文件，然后修改tomcat配置文件指定程序目录即可
<Host name="localhost" appBase="/data/www/jenkins"
unpackWARs="true" autoDeploy="true">
启动tomcat: ./startup.sh
浏览器访问：http://172.20.0.1:8080/jenkins
二、Jenkins项目构建
1，安装maven插件，由于部分开发team使用了maven管理，这里需要安装maven插件，安装的是3.2.2版本；
2，私服配置,如下
vim /root/.m2/settings.xml
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<!--将此文件放在目录(~/.m2)下做为maven的设置文件-->
<servers>
<server>
<id>snapshots</id>
<username>deployment</username>
<password>deployment</password>
</server>
<server>
<id>releases</id>
<username>deployment</username>
<password>deployment</password>
</server>
</servers>
<mirrors>
<mirror>
<id>nexus</id>
<mirrorOf>*</mirrorOf>
<name>internal nexus repository</name>
<url>http://172.20.135.19:8080/nexus/content/groups/public/</url>
</mirror>
</mirrors>
<profiles>
<profile>
<id>nexus</id>
<repositories>
<repository>
<id>central</id>
<url>http://nisabi</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>
<pluginRepositories>
<pluginRepository>
<id>central</id>
<url>http://nisabi</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>true</enabled>
</snapshots>
</pluginRepository>
</pluginRepositories>
</profile>
</profiles>
<activeProfiles>
<activeProfile>nexus</activeProfile>
</activeProfiles>
</settings>
3，在jenkins操作界面---系统管理---插件管理中，安装git、go插件，svn已经默认安装，由于开发项目有用到go语言，这里需要安装go插件；
4，在jenkins操作界面新建一个项目，可以选择自由风格软件项目或maven项目，在配置中填写源码管理地址、授权帐号、Branches to build（分支名）、pom.xml（根据具体项目来写）、add-post-build-step-----execute shell;
5，在execute shell框中填写服务器脚本地址，保存即可
三、Python发布脚本

此脚本的功能说明如下：
1，将构建好的代码包，用rsync同步到生产环境服务器中转目录program；
2，通过ssh登录生产环境服务器，调用program_update.sh脚本，将中转目录program下的代码更新到站点程序目录，更新完之后如果站点访问有BUG，那么可以将program下的前一个版本代码进行回滚；
3，构建的代码包和上传到生产环境的代码包通过md5校验一致性；
4，项目构建发布成功后，发邮件给项目相关人员；
5，执行此脚本的日志输出到文件，可以进行查看问题；
program_update.sh
#!/bin/sh cd /data/program/passport /usr/bin/docker cp ROOT.war passport-web:/data/www/skyid/ mv ROOT.war ROOT`date +"%Y-%m-%d_%H-%M-%S"`.war
