DEVOPS技术实践_18:Jenkins的Pinpeline对于参数的使用

2024-02-15 17:20:04

因为最近使用Pipeline声明式语法构建项目，但是最近项目的参数设置较多，特地的来学习一下关于参数的调用和测试，主要式从一个大神那里学习的，结尾回贴上大神的博客链接

1 构建一个pipeline项目

2 编写jenkinsfile文件

import hudson.model.*;
pipeline{ 
    
    agent any
    stages{
        stage("Hello Pipeline") {
            steps {
                script {
                    println "Hello Pipeline!"
                    println env.JOB_NAME
                    println env.BUILD_NUMBER
                }
            }
        }
    }
 
}

3 设置pipeline

上面就是简单的参数调用，但是当项目的西安舒比较多的时候，需要一个很长篇幅的构建页面，

假如有十来个可变的参数，其中有几个是可以提取出来，没必要暴露出来，那么我们就可以把其他参数放入到一个json文件。这个json文件，可以存放在linux服务器上。

原则上，每一个有权限去构建这个job的人，需要去linux服务器上创建自己的名称的文件夹，这个文件夹下然后放一个json文件。

准备一个json文件，在这个文件定义一些需要的参数，为了方便，就直接从博主那里粘贴了

5 使用json调用参数

vi /tmp/test.json

{
    "NAME":"Lucy",
     "AGE":"18",
    "PHONE_NUMBER":"13912345678",
    "ADDRESS":"Haidian Beijing",
    "EMAIL":"lucy@demo.com",
    "GENDER":"male",
    "IS_MARRY":"false"
}

jenkinsfile文件

import hudson.model.*;
    pipeline{
    agent any
    environment {
    INPUT_JSON = "/tmp/test.json"      #原本的文档使用参数化构建，我这里直接使用pipeline的环境变量，效果一样
    }
    stages{
        stage("Hello Pipeline") {
            steps {
                script {
                    println "Hello Pipeline!"
                    println env.JOB_NAME
                    println env.BUILD_NUMBER
                }
            }
        }
    stage("Init paramters in json") {
        steps {
            script {
 
                println "read josn input file"
                json_file = INPUT_JSON? INPUT_JSON.trim() : ""
                prop = readJSON file : json_file
                name = prop.NAME? prop.NAME.trim() : ""
                println "Name:" + name
                }
            }
        }
     }
}

7 用完全的Jenkinsfile调用所有参数

import hudson.model.*;
    pipeline{
    agent any
    environment {
    INPUT_JSON = "/tmp/test.json"
    }
    stages{
        stage("Hello Pipeline") {
            steps {
                script {
                    println "Hello Pipeline!"
                    println env.JOB_NAME
                    println env.BUILD_NUMBER
                }
            }
        }
 
    stage("Init paramters in json") {
        steps {
            script {
 
                println "read josn input file"
                    json_file = INPUT_JSON? INPUT_JSON.trim() : ""
                    prop = readJSON file : json_file
                    name = prop.NAME? prop.NAME.trim() : ""
                    println "Name:" + name
                    age = prop.AGE? prop.AGE.trim() : ""
                    println "Age:" + age
                    phone = prop.PHONE_NUMBER? prop.PHONE_NUMBER.trim() : ""
                    println "Phone:" + phone
                    address = prop.ADDRESS? prop.ADDRESS.trim() : ""
                    println "Address:" + address
                    email = prop.EMAIL? prop.EMAIL.trim() : ""
                    println "Email:" + email
                    gender = prop.GENDER? prop.GENDER.trim() : ""
                    println "Gender:" + gender
                    is_marry = prop.IS_MARRY? prop.IS_MARRY.trim() : false
                    println "is_marry:" + is_marry
                }
            }
        }
     }
 
}
