一、配置凭证

生成令牌

管理凭证

添加凭证

填写信息

二、全局配置

docker-compose

version: \'3\'
services:
  jenkins:
    restart: always
    image: jenkins:latest
    container_name: jenkins
    ports:
      - \'8888:8080\'
      - \'50000:50000\'
    volumes:
      - /home/qiang/docker-compose/jenkins/data/jenkins_home:/var/jenkins_home
      - /home/qiang/docker-compose/jenkins/data/war/jenkins.war:/usr/share/jenkins/jenkins.war

查看位置

[root@6e169b02437d jenkins_home]# pwd
/home/qiang/docker-compose/jenkins/data/jenkins_home
[root@6e169b02437d jenkins_home]# mkdir -p software/maven_home
[root@6e169b02437d jenkins_home]# mkdir -p software/jdk_home

        <activation>  
            <activeByDefault>true</activeByDefault>

            <maven.compiler.target>1.8</maven.compiler.target>  
            <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>  
        </properties>  
    </profile>
  </profiles>
</settings>

添加配置

三、新建任务

构建一个Maven项目

输入项目地址和刚刚添加的凭证

Maven执行打包命令

保存并尝试构建一下

构建成功

四、远程推送

填写服务器信息

配置推送到远程服务器

推送成功

五、构建镜像

开放Docker远程API

# 编辑文件
vim /etc/systemd/system/docker.service
# 修改内容
ExecStart=/usr/bin/dockerd -H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375
# 重启服务
systemctl daemon-reload && systemctl restart docker
# 测试验证
docker -H 192.168.8.246:2375 images

Jenkins链接Docker

Docker拥有的容器

准备Dockerfile

# 指定基础镜像
FROM 192.168.8.247/xiaoqiangzai/openjdk:8-jre
# 作者的信息
MAINTAINER wuduoqiang
# jar包的名字
ENV jar pavilion-1.0.0.jar
# 工作的目录
ENV workDir /app/
# 进入到容器后进入到哪个目录
WORKDIR ${workDir}
# 将文件拷贝到镜像中
COPY pavilion/target/${jar} ${workDir}
# 设置时区为上海
ENV TZ=Asia/Shanghai
RUN ln -snf /usr/share/zoneinfo/$TZ /etc/localtime && echo $TZ > /etc/timezone
# 容器启动时候执行的命令
CMD ["sh","-ec","exec java -jar ${jar} 2>&1 >> ${workDir}msg.log"]

构建成功

推送成功

六、定时删除

镜像策略

定时任务

七、启动服务

docker-compose

version: "3.0"
services:
  pavilion:
    image: 192.168.8.247/xiaoqiangzai/pavilion:{BUILD_ID}
    container_name: pavilion
    restart: always
    privileged: true
    ports:
      - "8080:8080"

将之前推送的jar包改成推送docker-compose

启动脚本

echo "停止旧服务"
docker stop $(docker ps -aq -f \'name=pavilion\') && docker rm $(docker ps -aq -f\'name=pavilion\')
echo "删掉旧镜像"
docker rmi $(docker images -aq -f \'reference=192.168.8.247/xiaoqiangzai/pavilion:*\')
echo "启动新镜像"
eval sed -in \'s#{BUILD_ID}#\'$BUILD_ID\'#\' /home/qiang/jenkins/pavilion/docker-compose.yaml
rm -rf /home/qiang/jenkins/pavilion/docker-compose.yamln
docker-compose -f /home/qiang/jenkins/pavilion/docker-compose.yaml up -d

构建成功

上传成功
