Jenkins集群下的pipeline实战，pipeline

关于Jenkins集群

在《快速搭建Jenkins集群》一文中，我们借助docker快速搭建了Jenkins集群，今天就在这个集群环境中创建pipeline任务，体验Jenkins集群下的并行任务；

环境信息

整个集群环境一共有三台电脑，信息如下：
| 主机名 | IP地址 | 作用 |
|--|--|--|
| master | 192.168.133.131 | Jenkins集群的master节点，提供web服务 |
| agent1 | 192.168.133.132 | Jenkins集群的一号工作接节点，标签是maven |
| agent2 | 192.168.133.133 | Jenkins集群的二号工作接节点，标签是gradle |

实战内容

本次实战要体验Jenkins集群同时执行两个任务，都是编译构建GitHub上的热门开源项目：

准备工作

要做以下准备工作才能顺利执行后续的任务：

docker exec -it agent /bin/bash

[root@agent1 16]# docker exec -it agent /bin/bash
root@82eb8cfec0a6:/# ssh root@192.168.133.131
The authenticity of host '192.168.133.131 (192.168.133.131)' can't be established.
ECDSA key fingerprint is SHA256:DPE2nldWHiOhC4DB9doy7jPWNZVup6XFZ+sR2i1gqz8.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.133.131' (ECDSA) to the list of known hosts.
root@192.168.133.131's password: 
Last login: Sat Nov 16 19:59:42 2019 from 192.168.133.132

至此，准备完毕，可以创建任务了；

编译构建spring-cloud-alibaba的任务

spring-cloud-alibaba是个maven工程，要用maven来编译构建：

pipeline {
    agent {
        label 'maven'
    }
    tools {
        maven 'mvn-3.6.2'
    }
    stages {
        stage('Checkout') {
            steps {
                echo '从GitHub下载spring-cloud-alibaba工程的源码(2.1.1.RELEASE归档包)'
                sh 'wget https://github.com/alibaba/spring-cloud-alibaba/archive/v2.1.1.RELEASE.tar.gz'
                echo '下载结束，解压归档包'
                sh 'tar -zxf v2.1.1.RELEASE.tar.gz'
            }
        }        
        stage('Build') {
            steps {
                echo '开始编译构建'
                sh 'cd spring-cloud-alibaba-2.1.1.RELEASE && mvn clean package -U -DskipTests'
            }
        }
        stage('Save') {
            steps {
                echo '将构建结果传送到存储服务器'
                sh 'cd spring-cloud-alibaba-2.1.1.RELEASE/spring-cloud-alibaba-nacos-discovery/target && sshpass -p 888888 scp ./*.jar root@192.168.133.131:/usr/local/build_result'
                echo '传送完毕'
            }
        }
        stage('Clean') {
            steps {
                echo '清理Maven工程'
                sh 'cd spring-cloud-alibaba-2.1.1.RELEASE && mvn clean'
                echo '清理完毕'
            }
        }
    }
}

pipeline {
    agent {
        label 'gradle'
    }

    stages {
        stage('Checkout') {
            steps {
                echo '从GitHub下载spring-framework工程的源码(master分支)'
                checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[url: 'https://github.com/spring-projects/spring-framework.git']]])
            }
        }        
        stage('Build') {
            steps {
                echo '开始编译构建'
                sh './gradlew build'
            }
        }
        stage('传送构建结果') {
            steps {
                echo '将构建结果传送到存储服务器'
                sh 'cd spring-core/build/libs && sshpass -p 888888 scp ./*.jar root@192.168.133.131:/usr/local/build_result && cd ../../..'
                echo '传送完毕'
            }
        }
        stage('Clean') {
            steps {
                echo '清理gradle工程'
                sh './gradlew clean'
                echo '清理完毕'
            }
        }
    }
}

[root@master build_result]# ls
agent.jar                      spring-cloud-alibaba-nacos-discovery-2.1.1.RELEASE.jar          spring-cloud-alibaba-nacos-discovery-2.1.1.RELEASE-sources.jar  spring-objenesis-repack-3.1.jar
spring-cglib-repack-3.3.0.jar  spring-cloud-alibaba-nacos-discovery-2.1.1.RELEASE-javadoc.jar  spring-core-5.2.2.BUILD-SNAPSHOT.jar

至此，Jenkins集群下的pipeline实战就完成了，借助pipeline的标签参数可以控制任务的调度节点，实现多任务同时在多节点执行；
