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: ‘[email protected]: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
