###### jenkins教程：jenkinsfile语法之parameters、triggers ######

![在这里插入图片描述][eee72ac20ae449d68944508d5b8dcfb9.png]

###### parameters ######

`parameters` 指令定义 pipeline的专有参数列表，支持参数类型:

*  `string`：字符串类型
 *  `text`：文本, 可包括多行
 *  `booleanParam`：布尔参数
 *  `choice`：choice 参数
 *  `password`：密码参数

示例脚本：

pipeline {
        agent any
        parameters {
            string(name: 'DEPLOY_ENV', defaultValue: 'staging', description: '') 
            text(name: 'DEPLOY_TEXT', defaultValue: 'One\nTwo\nThree\n', description: '') 
            booleanParam(name: 'DEBUG_BUILD', defaultValue: true, description: '')
            choice(name: 'CHOICES', choices: ['one', 'two', 'three'], description: '')
            password(name: 'PASSWORD', defaultValue: 'SECRET', description: 'A secret password')
        }
        stages {
            stage('Example') {
                steps {
                    echo "${params.DEPLOY_ENV}"
                    echo "${params.PASSWORD}"
                }
            }
        }
    }

###### triggers ######

`triggers` 指令定义了 Pipeline自动化触发的方式，主要包括3种触发器：

*  `cron`：接受一个cron样式的字符串来定义 Pipeline触发的间隔周期，例如: `triggers { cron('H */4 * * 1-5') }`
 *  `pollSCM`：接受一个cron样式的字符串来定义 Jenkins检查SCM源码更新的常规间隔；如果存在新的更改，Pipeline将被重新触发。例如: `triggers { pollSCM('H */4 * * 1-5') }`
 *  `upstream`：接受以逗号分隔的job字符串和阈值。当字符串中的任何作业以最小阈值完成时，将重新触发Pipeline。例如: `triggers { upstream(upstreamProjects: 'job1,job2', threshold: hudson.model.Result.SUCCESS) }`

更多cron表达式语法介绍可参考 [Linux cron定时介绍][Linux cron]。

示例脚本：

pipeline {
        agent any
        triggers {
            cron('H */4 * * 1-5')
        }
        stages {
            stage('init') {
                steps {
                    echo 'Hello World'
                }
            }
        }
    }
