Question

简而言之，我需要编写jenkinsfile管道，其中包含选择，并且这些选择来自另一个提供该地图的地图的groovy脚本，我可以添加环境名称和3个值DB，APP，WEB，因此当我开始构建新作业时我可以选择参数build来选择环境名称DEV，QA和UAT，根据此选择，它将传递DB / APP，WEB的三个IP的映射/列表，因此我可以在构建期间使用此值

/env.groovy

def DEV = [ DB : 10.0.0.5 , APP : 10.0.0.10 , WEB : 10.0.0.15 ] 
def UAT = [ DB : 10.0.0.20 , APP : 10.0.0.25 , WEB : 10.0.0.30 ] 
def QA = [ DB : 10.0.0.35 , APP : 10.0.0.40 , WEB : 10.0.0.45 ]

从env.groovy文件中获取此值，并将其传递给Jenkinsfile中的选项，这样我就可以通过（DEV-UAT-QA）获得下拉菜单在我点击构建

之前

我不想在Jenkinsfile中添加此值，我需要将其添加到单独的groovy脚本（env.groovy）

这是针对在ubuntu Jenkins服务器上运行的新管道Jenkinsfile

String[] env =  env()

pipeline {
    agent any
    properties([
            parameters([
                    choice(
                    choices: env,
                    description: 'Select the environment',
                    name: 'ENV',
                    )
            ])
    ])

    stages {
        stage('deploy') {
            steps {
                sh "echo ${ENV}"
            }
        }    
   }    
}

期望回显环境变量DB，APP和WEB的列表，因此我可以确定可以将此值传递给稍后将添加以部署的另一个Shell脚本，但是我没有在第一位置得到此菜单我得到这个错误

恕我直言，不可能将变量直接用作地图名称，但是我们有switch语句。

尝试以下方法：

def map

pipeline {
    agent any

    parameters {
            choice( name: 'env', choices: ['DEV', 'UAT', 'QA'] , description: "Choose ENV?" )
    }

    stages {
        //I'm a bit lazy, in Your case use regular file :) 
        stage('create file') {
            steps {
                script {
                    sh "echo \"DEV = [ DB : '10.0.0.5' , APP : '10.0.0.10' , WEB : '10.0.0.15' ]\" > env.groovy"
                    sh "echo \"UAT = [ DB : '10.0.0.20' , APP : '10.0.0.25' , WEB : '10.0.0.30' ]\" >> env.groovy"
                    sh "echo \"QA = [ DB : '10.0.0.35' , APP : '10.0.0.40' , WEB : '10.0.0.45' ]\" >> env.groovy"
                }
            }
        }
        stage('switch time') {
            steps {
                script{
                    load "$JENKINS_HOME/workspace/box1/env.groovy"
                    switch (params.env) {
                    case 'DEV':
                        map = DEV
                        break
                    case 'UAT':
                        map = UAT
                        break
                    case 'QA':
                        map = QA
                        break
                    default:
                        map = []
                        break
                    }
                }
            }
        }
        stage('deploy') {
            steps {
                println map.DB
                println map.APP
                println map.WEB
            }
        }
    }
}
