Jenkins: Environment

 

Jenkins 环境变量就是通过 env 关键字暴露出来的全局变量，可以在 Jenkins 文件的任何位置使用

 

查看 Jenkins 系统内置环境变量

1. ${JENKINS_URL}/env-vars.html
   
   
2. through pipeline
   

   pipeline {
       agent any
       stages {
           stage('Environment') {
               steps {
                   sh 'printenv | sort'
               }
           }
   }

    

 

 

 

 

 

 

Shell 结果赋值给环境变量

实现这种方式很简单，只需要记住一个格式：sh(script: 'cmd', returnStdout:true)

 

environment {
    v1=11
}


env.v5=5555555
def v6=666666


pipeline {
    agent any
    environment {
        v2=22
    }
    options {
        ansiColor('xterm')
    }

    stages {
        stage('Hello') {
            environment {
                v7=77777777
                LS="${sh(script:'ls -alh', returnStdout: true)}"
            }
            steps {
                // environment can't locate in steps
                
                echo '${env.BUILD_NUMBER}'
                echo "${env.BUILD_NUMBER} ${v6}"  // can't access v4
                echo "LS = ${env.LS}"
                
                // def b=8888  should use in script {}
                
                withEnv(['t=tttttttttttt', "tt=${JENKINS_URL}"]) {  // can override any env variables
                    sh '''
                        env | sort
                    '''
                }
                script {
                    env.v3=33
