Jenkins(八)

欢迎关注我公众号呀～「测试游记」「zx94_11」

参数化流水线

Jenkins pipeline中定义参数使用parameters指令，只允许放在pipeline块下

在http://127.0.0.1:8080/directive-generator/可以自动生成

生成

parameters {
  booleanParam defaultValue: false, description: '布尔值参数', name: 'FLAG'
}

• defaultValue:默认值
• description:描述信息
• name:参数名

使用方法：${params.FLAG}

pipeline {
    agent any
    parameters {
        booleanParam(defaultValue: true,description: '',name:'userFlag')
    }
    stages {
        stage('foo'){
            steps {
                echo "flag: ${params.userFlag}"
            }
        }
    }
}

支持的参数类型

• string

parameters {
  string defaultValue: 'none', description: '666', name: 'D_ENV', trim: true
}

字符参数

• text

parameters {
  text defaultValue: 'a\nb\nc\n', description: '', name: 'D_TEXT'
}

• booleanParam
• choice

parameters {
  choice choices: 'a\nb\nc\n', description: '', name: 'D_CHOICE'
}

• file(有BUG不要用)
• password

parameters {
  password name: 'a\nb\nc\n', description: '', name: 'D_CHOICE'
}

综上：

parameters {
      string defaultValue: 'none', description: '字符串', name: 'D_ENV', trim: true
      text defaultValue: 'a\nb\nc\n', description: '文本', name: 'D_TEXT'
      choice choices: 'a\nb\nc\n', description: '选一个', name: 'D_CHOICE'
      booleanParam defaultValue: false, description: '布尔值参数', name: 'FLAG'
      password name: 'PASSWORD',defaultValue:'SECRET',description: 'password'
   }

Extended Choice Parameter

一个实现复杂的参数化选择的插件

https://wiki.jenkins.io/display/JENKINS/Extended+Choice+Parameter+plugin

插件安装

使用官网的一个例子：

import org.boon.Boon;
 
def jsonEditorOptions = Boon.fromJson(/{
        disable_edit_json: true,
        disable_properties: true,
        no_additional_properties: true,
        disable_collapse: true,
        disable_array_add: true,
        disable_array_delete: true,
        disable_array_reorder: true,
        theme: "bootstrap2",
        iconlib:"fontawesome4",
        schema: {
          "title": "Color Picker",
          "type": "object",
          "properties": {
            "color": {
              "type": "string",
              "format": "color"
            }
          }
        },
        startval: {
            color :"red"
        }
}/);

      stage('Example'){
         steps{
            withPythonEnv('/usr/bin/python'){
               sh 'python -m pip install pytest '
               sh 'python -m pip install allure-pytest'
               sh 'python -m pytest -v test_allure.py --alluredir=allure-results'
            }
            exit 0
         }
      }
   }
   post{
      always{
         allure includeProperties: false, jdk: '', results: [[path: 'allure-results']]
      }
   }
}

可以发现这段Groovy代码太长了，所以将它进行提取

创建共享库

共享库

新建一个sayHello.groovy文件

def call() {
  return """
  import org.boon.Boon;
def jsonEditorOptions = Boon.fromJson(/{
        disable_edit_json: true,
        disable_properties: true,
        no_additional_properties: true,
        disable_collapse: true,
        disable_array_add: true,
        disable_array_delete: true,
        disable_array_reorder: true,
        theme: "bootstrap2",
        iconlib:"fontawesome4",
        schema: {
          "title": "Color Picker",
          "type": "object",
          "properties": {
            "color": {
              "type": "string",
              "format": "color"
            }
          }
        },
        startval: {
            color :"red"
        }
}/);
  """
}

使用共享库

修改Jenkinsfile为：

导包@Library('extended-library') _

引用：sayHello()

@Library('extended-library') _
pipeline {
   agent any
   parameters {
      extendedChoice bindings: '', description: '', groovyClasspath: '', groovyScript: sayHello(), multiSelectDelimiter: ',', name: 'Policy', quoteValue: false, saveJSONParameterToFile: false, type: 'PT_JSON', visibleItemCount: 5
   }
   stages {
      stage('build') {
         steps{
            echo "Hello"
            }
      }
   }
}
