在 Jenkins Pipeline 中使用全局变量 [英] Using global variables in Jenkins Pipeline
本文介绍了在 Jenkins Pipeline 中使用全局变量的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我尝试了各种方法，但似乎没有任何效果.这是我的詹金斯档案.
I have tried all sort of ways but nothing seems to be working. Here is my jenkinsfile.
def ZIP_NODE
def CODE_VERSION
pipeline{
/*A declarative pipeline*/
agent {
/*Agent section*/
// where would you like to run the code
label 'ubuntu'
}
options{
timestamps()
}
parameters {
choice(choices: ['dev'], description: 'Name of the environment', name: 'ENV')
choice(choices: ['us-east-1', 'us-west-1','us-west-2','us-east-2','ap-south-1'], description: 'What AWS region?', name: 'AWS_DEFAULT_REGION')
string(defaultValue: "", description: '', name: 'APP_VERSION')
}
stages{
/*stages section*/
stage('Initialize the variables') {
// Each stage is made up of steps
steps{
script{
CODE_VERSION='${BUILD_NUMBER}-${ENV}'
ZIP_NODE='abcdefgh-0.0.${CODE_VERSION}.zip'
}
}
}
stage ('code - Checkout') {
steps{
checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'xxxxxxxxxxxxxxxxxxxxxxxxxx', url: 'http://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.git']]])
}
}
stage ('code - Build'){
steps{
sh '''
echo ${JOB_NAME}
pwd
echo ${ZIP_NODE}
echo 'remove alraedy existing zip files'
rm -rf *.zip
zip -r ${ZIP_NODE} .
chmod 777 $ZIP_NODE
'''
}
}
stage('Deploy on Beanstalk'){
steps{
build job: 'abcdefgh-PHASER' , parameters: [[$class: 'StringParameterValue', name: 'vpc', value: ENV], [$class: 'StringParameterValue', name: 'ZIP_NODE', value: ZIP_NODE], [$class: 'StringParameterValue', name: 'CODE_VERSION', value: CODE_VERSION], [$class: 'StringParameterValue', name: 'APP_VERSION', value: BUILD_NUMBER], [$class: 'StringParameterValue', name: 'AWS_DEFAULT_REGION', value: AWS_DEFAULT_REGION], [$class: 'StringParameterValue', name: 'ParentJobName', value: JOB_NAME]]
}
}
}
}
阶段脚本的输出('初始化变量')什么也没给我，它没有设置全局变量 ZIP_NODE 的值:
The output of step script in stage ('Initialize the variables') gives me nothing, It is not setting the value of global variable ZIP_NODE:
[Pipeline] stage
[Pipeline] { (Initialize the variables)
[Pipeline] script
[Pipeline] {
[Pipeline] }
[Pipeline] // script
[Pipeline] }
[Pipeline] // stage
然后我们进入阶段(代码 - 构建)我们没有得到 ZIP_NODE 的值.见 22:34:17 的 echo 声明
And then we go to stage (code - Build) we do not get the value of ZIP_NODE. See echo statement at 22:34:17
[Pipeline] stage
[Pipeline] { (code - Build)
[Pipeline] sh
22:34:16 [abcdefgh-ci-dev-pipeline] Running shell script
22:34:17 + echo abcdefgh-ci-dev-pipeline
22:34:17 abcdefgh-ci-dev-pipeline
22:34:17 + pwd
22:34:17 /home/advisor/Jenkins/workspace/abcdefgh-ci-dev-pipeline
22:34:17 + echo
22:34:17
22:34:17 + echo remove alraedy existing zip files
感谢@awefsome，我有一些观察，我想补充一些细节:当我使用下面的代码时，我得到了所需的输出，即 ZIP_NODE 的正确值:
Thanks to @awefsome, I had some observation which I would like add in details: When I use below code I get desired output i.e. correct value of ZIP_NODE:
stage ('code - Build'){
steps{
sh "echo ${JOB_NAME} && pwd && echo ${ZIP_NODE} && echo 'remove alraedy existing zip files' && rm -rf *.zip && zip -r ${ZIP_NODE} . && chmod 777 $ZIP_NODE"
}
}
但是当我使用下面的代码时，我没有得到 ZIP_NODE 的值:
But when I use below code I do not get the value of ZIP_NODE:
stage ('code - Build'){
steps{
sh '''
echo ${ZIP_NODE}
echo ${JOB_NAME}
pwd
echo ${ZIP_NODE}
echo ${CODE_VERSION}
#rm -rf .ebextensions
echo 'remove alraedy existing zip files'
rm -rf *.zip
zip -r ${ZIP_NODE} .
chmod 777 $ZIP_NODE
'''
}
}
推荐答案
尝试以下操作，看看效果如何:
Try following and see how it goes:
def ZIP_NODE
def CODE_VERSION
pipeline{
/*A declarative pipeline*/
agent {
/*Agent section*/
// where would you like to run the code
label 'master'
}
options{
timestamps()
}
parameters {
choice(choices: ['dev'], description: 'Name of the environment', name: 'ENV')
choice(choices: ['us-east-1', 'us-west-1','us-west-2','us-east-2','ap-south-1'], description: 'What AWS region?', name: 'AWS_DEFAULT_REGION')
string(defaultValue: "", description: '', name: 'APP_VERSION')
}
stages{
/*stages section*/
stage('Initialize the variables') {
// Each stage is made up of steps
steps{
script{
CODE_VERSION="${BUILD_NUMBER}-${ENV}"
ZIP_NODE="abcdefgh-0.0.${CODE_VERSION}.zip"
}
}
}
stage ('code - Checkout') {
steps{
println "checkout skipped"
//checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'xxxxxxxxxxxxxxxxxxxxxxxxxx', url: 'http://xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.git']]])
}
}
stage ('code - Build'){
steps{
sh "echo ${JOB_NAME} && pwd && echo ${ZIP_NODE} && echo 'remove alraedy existing zip files' && rm -rf *.zip && zip -r ${ZIP_NODE} . && chmod 777 $ZIP_NODE"
}
}
stage('Deploy on Beanstalk'){
steps{
println "build job skipped"
//build job: 'abcdefgh-PHASER' , parameters: [[$class: 'StringParameterValue', name: 'vpc', value: ENV], [$class: 'StringParameterValue', name: 'ZIP_NODE', value: ZIP_NODE], [$class: 'StringParameterValue', name: 'CODE_VERSION', value: CODE_VERSION], [$class: 'StringParameterValue', name: 'APP_VERSION', value: BUILD_NUMBER], [$class: 'StringParameterValue', name: 'AWS_DEFAULT_REGION', value: AWS_DEFAULT_REGION], [$class: 'StringParameterValue', name: 'ParentJobName', value: JOB_NAME]]
}
}
}
}
我得到以下输出:
