在詹金斯管道中使用全局变量

我尝试了各种方法，但似乎没有任何效果。这是我的詹金文件。

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”）没有任何作用，不是设置全局变量ZIP_NODE的值：

[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-生成），我们没有获得ZIP_NODE的值。请参阅22:34:17的echo声明

[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

由于@awefsome，我有一些观察，我想补充一下： 当我使用以下代码时，我会得到所需的输出，即ZIP_NODE的正确值：

 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：

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 
                    '''
            }
        }

sh '''
'''

应该是

sh """
"""

用单引号引起来的变量将不被处理。

尝试以下操作，看看它如何运行：

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：

詹金斯上的全局环境应该在管道之外，可以在脚本内部进行初始化/使用，当然，管道内的所有作用域都可以知道：

示例：

def internal_ip

pipeline {
    agent { node { label "test" } }
        stages {
            stage('init') {
                steps {
                    script {
                        def x
                        if(env.onHold.toBoolean() == true){
                            x=1
                        }else{
                            x=2
                        }
                        internal_ip = sh (
                            script: "echo 192.168.0.${x}",
                            returnStdout: true
                        ).trim()   
                    }
                }
            }
            stage('test') {
                steps {
                    script {
                        echo  "my internal ip is: ${internal_ip}"
                    }
                }
            }
        }    
    }
}

我在 groovy shellscript 中使用全局变量的经验是将它们声明为全局变量，然后使用 stage 环境变量。看起来shell脚本只能访问这个私有环境变量而不是全局变量。作为示例：

environment{
  COMMIT_ID = "foo"
}               
stages{
stage('Build'){
  environment {
    commitId = sh(returnStdout: true, script: 'git rev-parse HEAD').trim()
  }
  steps {
    script {
      COMMIT_ID = commitId
    }
  }
}
stage ('Build-Win-Container'){
  environment {
    commitId = "${COMMIT_ID}"
  }
  steps{
    sh label: 'build/push container', script: '''
    echo "With Windows commitId: ${commitId}"
    '''
  }
}
}

我也从 stackoverflow 尝试了多种方法，但没有一种方法可以访问 shell 脚本中的变量。我认为这是因为 shell 脚本是一个步骤中的私有实例，并且只能访问此步骤中的变量（我的意见） 所以我设置了一个全局环境变量 用脚本在第 1 步中填写此内容 在下一步中设置一个环境变量并在那里填写。 最后它在 shell 脚本中可用。没有其他方法对我有用。
