Jenkins on docker 编译一个maven java app.

本文简述如何用Jenkins 来自动编译一个java maven 项目。

1. 在安装有docker 的机器上， 安装并运行Jenkins:

docker run -d  -u root -p 8080:8080 -v /data/elk/jenkins-data:/var/jenkins_home -v /var/run/docker.sock:/var/run/docker.sock  -v "$HOME":/home  jenkinsci/blueocean   

2. 查看初始安装密码（78位container id 缩写）

#  docker exec -it 78 cat /var/jenkins_home/secrets/initialAdminPassword
06726df821f542d6a5e6a9bf220a0a6c

3. 访问启动的Jenkins, 并根据wizard填入上面密码， 默认安装配置完毕
   http://xx.xx.xx.xx:8080

4. git clone 你的maven project 到/home映射的path.

5. 在maven 本地clone根目录下写vi Jenkinsfile
   注意配置maven仓库位置

pipeline {
    agent {
        docker {
            image 'maven:3-alpine'
            args '-v /root/.m2:/root/.m2'
        }
    }
    stages {
        stage('Build') {
            steps {
                sh 'mvn -B -DskipTests clean package'
            }
        }
        stage('Test') {
            steps {
                sh 'mvn test'
            }
            post {
                always {
                    junit 'target/surefire-reports/*.xml'
                }
            }
        }
        stage('Deliver') { 
            steps {
                sh './jenkins/scripts/deliver.sh' 
            }
        }
    }
}

6. git add . && git commit -m "Add initial Jenkinsfile"

7. 创建 Pipeline project in Jenkins
