使用Jenkins Pipeline自动化构建发布Java项目的方法
人气:0简介
Pipeline,简而言之,就是一套运行于Jenkins上的工作流框架,将原本独立运行于单个或者多个节点的任务连接起来,实现单个任务难以完成的复杂流程编排与可视化。
Pipeline是Jenkins2.X的最核心的特性,帮助Jenkins实现从CI到CD与DevOps的转变。
一,创建pipeline项目
二,清除部分历史构建
三,参数化构建
这里使用三个参数,分别对应是否拉取代码,项目名称,以及发版选项
四,编写pipeline脚本
选择pipeline script
编写pipeline脚本
def userMap def proMap = ['api': 'test_api', 'report':'test_report', 'job': 'test_job'] //定义项目字典 def deployMap = ['test-pipeline': 'test-pro.sh'] //定义发版脚本 def predeployMap = ['test-pipeline': 'test-pre.sh'] //定义预发布脚本 def rollbackMap = ['test-pipeline': 'test-pro-rollback.sh'] //定义回滚脚本 pipeline { agent any //parameters { string(defaultValue: '', name: 'PULL_FLAG', description: '请根据发布类型进行选择发布:\n1,输入-TESTING-发布-最新代码-到灰度\n2,输入-LATEST-发布-最新代码-到生产\n3,输入-版本号-发布-制定版本-到生产 ' ) } stages { stage('Checkout') { when { //判断是否要拉取代码 environment name: 'PULL_FLAG', value: 'yes' } steps { echo "${PULL_FLAG}" //拉取代码 checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [[$class: 'CleanBeforeCheckout']], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '797fddfc-d9d6-42a7-9a2b-38421a6963b0', url: 'git@git.test.com:test/test.git']]]) echo 'Checkout' } } stage('Build') { when { environment name: 'PULL_FLAG', value: 'yes' } steps { echo 'Building' // 使用maven进行构建 sh 'mvn clean install -Dmaven.test.skip=true -Pprod' } } stage('Push package') { when { environment name: 'PULL_FLAG', value: 'yes' } steps { echo 'push package' //上传war包至跳板机 sh 'sh /srv/shell/PAY_scp_pipe.sh ' } } stage('Deploy/Rollback') { steps { //定义发版密码校验,只有输入口令正确,才会发版到线上机器,密码保存在环境变量中 timeout(60) { script { userMap = input message: 'please input password', ok: 'ok', submitter: 'admin', parameters: [password(name:'password', defaultValue: '', description: '发布代码口令' )], submitterParameter: 'admin' if (userMap['password'].toString() == PASSWORD) { echo '密码正确' if (DEPLOY_FLAG == 'deploy') { echo "发版" sh "ssh test 'cd /data/faban && sh ${deployMap[env.JOB_NAME]} ${proMap[PROJECT]}'" }else if (DEPLOY_FLAG == 'predeploy') { echo '预发布' sh "ssh test 'cd /data/faban/pre-release && sh ${predeployMap[env.JOB_NAME]} ${proMap[PROJECT]}'" }else if (DEPLOY_FLAG == 'rollback') { echo '回滚' sh "ssh test 'cd /data/faban && sh ${rollbackMap[env.JOB_NAME]} ${proMap[PROJECT]}'" } }else { echo '密码错误' echo "${env.JOB_NAME}" } } } } } } post { always { echo 'This will always run' //发版结束后删除jenkins workspace下的临时目录 deleteDir() } success { echo 'This task is successful!' //记录日志信息 sh """ printf '%s %s %s %s %s %s' `date +'%F %H:%M:%S'` "${env.JOB_NAME}" "${proMap[PROJECT]}" "${DEPLOY_FLAG}" "success!\n" >> /srv/jk_logs/jk.log """ } } }
五,用到的shell脚本
1, 上传war包的脚本 /srv/shell/TEST_scp_pipe.sh
#!/bin/bash scp -r /srv/jenkins/workspace/test/test/api/target/api.war test:/data/faban/server_war/risk_api.war scp -r /srv/jenkins/workspace/test/test/report/target/report.war test:/data/faban/server_war/risk_report.war scp -r /srv/jenkins/workspace/test/test/job/target/job.war test:/data/faban/server_war/risk_job.war
2, 发版脚本(跳板机)
#!/bin/bash project="$1" java_config=/data/faban/java_config war_rebuild=/data/faban/war_rebuild if [ $# -lt 1 ]; then echo "usage: $0 <project>" exit 1 fi case "$project" in test_api) tomcat=/opt/tomcat_api server="test" ;; test_report) tomcat=/opt/tomcat_report server="test" ;; test_job) tomcat=/opt/tomcat_job server="test" ;; esac rm -rf $war_rebuild/* rsync -av /data/faban/server_war/$project.war /data/faban/war_rebuild cd $war_rebuild ssh $server "pkill -9 -f $tomcat" ssh $server "rm -rf $tomcat/webapps/ROOT; mv $tomcat/webapps/ROOT.war $tomcat/webapps/ROOT.war.bak" scp $project.war $server:$tomcat/webapps/ROOT.war ssh $server "chown www.www $tomcat/webapps/ROOT.war" ssh $server "su - www -c $tomcat/bin/startup.sh" sleep 5
3, 回滚脚本(跳板机)
#!/bin/bash project="$1" if [ $# -lt 1 ]; then echo "usage: $0 <project>" exit 1 fi case "$project" in test_api) tomcat=/opt/tomcat_api server="test" ;; test_report) tomcat=/opt/tomcat_report server="test" ;; test_job) tomcat=/opt/tomcat_job server="test" ;; esac ssh $server "pkill -9 -f $tomcat" ssh $server "rm -rf $tomcat/webapps/ROOT; mv $tomcat/webapps/ROOT.war.bak $tomcat/webapps/ROOT.war" ssh $server "su - www -c $tomcat/bin/startup.sh" sleep 5
