Jenkins 管道条件环境变量

Question

我在声明性管道的 environmental 指令部分中有一组静态环境变量。这些值可用于管道中的每个阶段。
我希望根据任意条件更改值。
有没有办法做到这一点？

pipeline {
   agent any
   environment {
     if ${params.condition} {
     var1 = '123'
     var2 = abc
    } else {
     var1 = '456'
     var2 = def
     }
   }
   stages {
     stage('One') {
      steps {
        script {
        ...
        echo env.var1
        echo env.var2            
        ...
     }
    }
   }
  }
  stag('Two'){
   steps {
        script {
        ...
        echo env.var1
        echo env.var2
        ...
     }
   }
 }

我建议您创建一个阶段“环境”并根据您想要的条件声明您的变量，如下所示:-

pipeline {
   agent any
   environment {
     // Declare variables which will remain same throughout the build
   }
   stages {
     stage('Environment') {
                agent  { node { label 'master' } }
                steps {
                    script {
                       //Write condition for the variables which need to change
                       if ${params.condition} {
                                 env.var1 = '123'
                                 env.var2 = abc
                                } else {
                                 env.var1 = '456'
                                 env.var2 = def
                                 }
                        sh "printenv"
                    }
                }
            }
         stage('One') {
          steps {
            script {
            ...
            echo env.var1
            echo env.var2            
            ...
         }
        }
       }
      stage('Two'){
       steps {
            script {
            ...
            echo env.var1
            echo env.var2
            ...
         }
       }
    }
    }
}
