站長資訊網簡介
Pipeline，簡而言之，就是一套運行于Jenkins上的工作流框架，將原本獨立運行于單個或者多個節(jié)點的任務連接起來，實現(xiàn)單個任務難以完成的復雜流程編排與可視化。
Pipeline是Jenkins2.X的最核心的特性，幫助Jenkins實現(xiàn)從CI到CD與DevOps的轉變。
一，創(chuàng)建pipeline項目
二，清除部分歷史構建
三，參數(shù)化構建
這里使用三個參數(shù)，分別對應是否拉取代碼，項目名稱，以及發(fā)版選項
四，編寫pipeline腳本
選擇pipeline script
編寫pipeline腳本
def userMap
def proMap = [‘api’: ‘test_api’, ‘report’:’test_report’, ‘job’: ‘test_job’] //定義項目字典
def deployMap = [‘test-pipeline’: ‘test-pro.sh’] //定義發(fā)版腳本
def predeployMap = [‘test-pipeline’: ‘test-pre.sh’] //定義預發(fā)布腳本
def rollbackMap = [‘test-pipeline’: ‘test-pro-rollback.sh’] //定義回滾腳本
pipeline {
agent any
//parameters { string(defaultValue: ”, name: ‘PULL_FLAG’, description: ‘請根據(jù)發(fā)布類型進行選擇發(fā)布：n1，輸入-TESTING-發(fā)布-最新代碼-到灰度n2，輸入-LATEST-發(fā)布-最新代碼-到生產n3，輸入-版本號-發(fā)布-制定版本-到生產 ‘ ) }
stages {
stage(‘Checkout’) {
when {
//判斷是否要拉取代碼
environment name: ‘PULL_FLAG’, value: ‘yes’
}
steps {
echo “${PULL_FLAG}”
//拉取代碼
checkout([$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進行構建
sh ‘mvn clean install -Dmaven.test.skip=true -Pprod’
}
}
stage(‘Push package’) {
when {
environment name: ‘PULL_FLAG’, value: ‘yes’
}
steps {
echo ‘push package’
//上傳war包至跳板機
sh ‘sh /srv/shell/PAY_scp_pipe.sh ‘
}
}
stage(‘Deploy/Rollback’) {
steps {
//定義發(fā)版密碼校驗，只有輸入口令正確，才會發(fā)版到線上機器，密碼保存在環(huán)境變量中
timeout(60) {
script {
userMap = input message: ‘please input password’, ok: ‘ok’, submitter: ‘admin’, parameters: [password(name:’password’, defaultValue: ”, description: ‘發(fā)布代碼口令’ )], submitterParameter: ‘admin’
if (userMap[‘password’].toString() == PASSWORD) {
echo ‘密碼正確’
if (DEPLOY_FLAG == ‘deploy’) {
echo “發(fā)版”
sh “ssh test ‘cd /data/faban && sh ${deployMap[env.JOB_NAME]} ${proMap[PROJECT]}'”
}else if (DEPLOY_FLAG == ‘predeploy’) {
echo ‘預發(fā)布’
sh “ssh test ‘cd /data/faban/pre-release && sh ${predeployMap[env.JOB_NAME]} ${proMap[PROJECT]}'”
}else if (DEPLOY_FLAG == ‘rollback’) {
echo ‘回滾’
sh “ssh test ‘cd /data/faban && sh ${rollbackMap[env.JOB_NAME]} ${proMap[PROJECT]}'”
}
}else {
echo ‘密碼錯誤’
echo “${env.JOB_NAME}”
}
}
}
}
}
}
post {
always {
echo ‘This will always run’
//發(fā)版結束后刪除jenkins workspace下的臨時目錄
deleteDir()
}
success {
echo ‘This task is successful!’
//記錄日志信息
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腳本
1， 上傳war包的腳本 /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， 發(fā)版腳本（跳板機）
#!/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， 回滾腳本（跳板機）
#!/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
