## 1. 安装 Jenkins + maven + jdk + git ##

## 2. spring boot 项目添加Dockerfile ##

这里没有使用dockermaven插件，直接原生 Dockerfile，保持代码侵入最低。

FROM 172.16.0.57:5000/openjdk:8-jdk-alpine
    MAINTAINER guzhongtao@middol.com
    VOLUME /var/log/tiannake/hibernate
    RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
    RUN echo 'Asia/Shanghai' >/etc/timezone
    ENV LANG zh_CN.UTF-8
    #ARG JAR_FILE
    #ADD ${JAR_FILE} app.jar
    ADD target/hibernate.jar app.jar
    ENTRYPOINT ["java","-Xms1024m","-Xmx1024m","-Dspring.profiles.active=test","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

FROM 172.16.0.57:5000/openjdk:8-jdk-alpine 这个是我的docker私服里面的基础镜像，去掉 172.16.0.57:5000则从 dockerhuber上下载该基础镜像。

VOLUME /var/log/tiannake/hibernate 这个是我springboot 日志打印的路径。

ADD target/hibernate.jar app.jar 这个我项目编译后统一路径在 target下面，编译的finalName是hibernate.jar

## 3. 配置 Jenkins 全局系统工具 ##

## 4. 配置 Jenkins 新建一个maven项目 ##

最重要的是编译后的shell脚本  
先删除容器，镜像后创建镜像，启动容器。

#!/bin/bash 
    
    #export BUILD_ID=dontKillMe这一句很重要，这样指定了，项目启动之后才不会被Jenkins杀掉。
    export BUILD_ID=dontKillMe
    
    echo "动态参数配置 begin===============>"
    CDNAME=hibernate-2.0
    echo "image and container name is $CDNAME"
    
    # springboot启动的端口号
    BootPort=8101
    echo "the spring boot port is $BootPort"
    
    # dockerfile里面指定的 Volume 即日志打印的路径
    dockerLogVolume=/var/log/tiannake/hibernate
    echo "the dockerLogVolume is $dockerLogVolume"
    
    # dockerfile里面指定的 Volume 映射外面磁盘的路径
    linuxLogPath=/log/docker/tannaike
    echo "the linuxLogPath is $linuxLogPath"
    echo "动态参数配置 end"
    
    
    echo "begin create the container..."
    echo "stop and delete container"
    CID=$(docker ps -a | grep "$CDNAME" | awk '{print $1}')
    
    if [ -n "$CID" ]; then
    echo "has container，CID=$CID"
    docker stop $CID
    docker rm $CID
    fi
    
    echo "delete image"
    IMD=$(docker image ls | grep "$CDNAME" | awk '{print $1}')
    
    if [ -n "$IMD" ]; then
    echo "has image，IMD=$IMD"
    docker rmi $IMD
    fi
    
    echo "pwd..."
    pwd
    
    echo "build docker image"
    # mvn dockerfile:build
    docker build -f Dockerfile -t $CDNAME:latest .
    
    echo "current docker images："
    docker images | grep $CDNAME
    
    echo "start container ===============> "
    docker run -d -p $BootPort:$BootPort -v $linuxLogPath:$dockerLogVolume --name $CDNAME $CDNAME:latest
    
    
    CID=$(docker ps | grep "$CDNAME" | awk '{print $1}')
    
    if [ -n "$CID" ]; then
    
    echo "============ start container，CID=$CID ============"
    echo "============ start container SUCCESS！============"
    
    else
    
    echo "============ start container FAIL ！！！！！============"
    
    fi
