简介
前面简单的做了管道的实验,看了一下的它的效果
声明式管道是Groovy语法中的一个更简单和结构化的语法。下面主要学习明式管道语法。
一 声明式管道的基本结构
以上节的代码为例
node { def mvnHome stage(‘Preparation‘) { // for display purposes // Get some code from a GitHub repository git ‘https://github.com/jglick/simple-maven-project-with-tests.git‘ // Get the Maven tool. // ** NOTE: This ‘M3‘ Maven tool must be configured // ** in the global configuration. mvnHome = tool ‘M3‘ } stage(‘Build‘) { // Run the maven build withEnv(["MVN_HOME=$mvnHome"]) { if (isUnix()) { sh ‘"$MVN_HOME/bin/mvn" -Dmaven.test.failure.ignore clean package‘ } else { bat(/"%MVN_HOME%\bin\mvn" -Dmaven.test.failure.ignore clean package/) } } } stage(‘Results‘) { junit ‘**/target/surefire-reports/TEST-*.xml‘ archiveArtifacts ‘target/*.jar‘ } }
1.1 node块
node块定义Jenkins agent,在node中定义了stage blocks, directives和steps.
node块的结构看起来如下所示:
node (‘‘) {}
下面给关于node块更详细的信息:
- – Defines: stge,directives或者steps应该运行的节点。
- – Constituents: 多个stage块、directives或steps.
- – Required: Yes
- – Parameters: Any, label
node (‘master’) { 这里的字符串master是一个参数,是告诉Jenkins去使用Jenkins master运行node里面的块内容。
如果是any的话,那就是所有的agnet的都可以去运行。
1.2 Stage块
stage块是一群相关对象的steps和directives的集合。stage块结构看起来如下所示:
stage (‘‘) {}
下面给出关于stage块的更详细信息。
- Defines: 一组steps和directives.
- Constituents: 多个node块、directives或者steps.
- Required: Yes
- Parameters: A string that is the name of the stage(mandatory)
1.3 Directives
指令的主要目标是给node block,stage block和 stage block提供以下元素:环境变量、选项、参数、触发器、工具。
下面给出了关于stage 块的更详细信息。
- Defines: 这个阶段应该运行的节点位置(就是在哪个节点上运行)。
- Constituents: Environments, options, parameters, triggers, tools
- Required: No, but every CI/CD pipeline has it.
- Parameters: None
1.4 Step
阶段是组成声明管道的基本元素。step可以是batch脚本或者shell脚本,或者其它任何可以执行的命令。 steps有多种多样的用处,比如刻隆代码,构建代码,运行测试,上传软件到repository server,执行静态代码分析等。 在上一章节,也看到了如何使用Jenkins管道语法工具。
下面给出了关于step块的更详细信息:
- Defines: 它告诉Jenkins干什么
- Constituents: 命令,脚本等。它也是管道的基本块。
- Required: No, 但每个CI/CD管道都有它。
- Parameters: None
二 jenkins语法管道工具
Jenkins pipeline syntax utility是快速简单的创建pipeline代码的方式。
下面学习使用pipeline syntax utility重新创建pipeline
2.1准备工作
安装一个插件
- 在Global Tool Configuration页面中配置Maven tool.
- 安装Pipleline Maven Integration Plugin.
- 构建Maven项目时需要Java工具,因此此处构建时使用Jenkins master.
2.2 使用pipeline syntax utility 创建Jenkins pipeline.
新建任务,取名jenkins_pineline_demo_utility,使用流水线
点击流水线的流水线语法
界面显示
2.3 连接一个node
复制过来
2.4 创建两个stage块,名字分别为Preparation和Build,并复制脚本到第(3)步的编辑器中
复制过来
2.5 Build操作
复制过来
2.6 创建一个step去从GitHub服务器下载源码。并把产生的代码复制,放到Preparation 的stage块中
复制过来
2.7 产生指令告诉jenkins去使用我们先前在【全局工具配置】的M3 maven工具。,然后把代码复制到Build的stage块中
复制代码过来
2.8 针对Maven 构建命令产生一个pipeline的代码。然后把脚本内容复制到withMaven指令中去
复制代码
最终代码如下
node(‘master‘) { // some block stage(‘Preparation‘) { // some block //step git ‘https://github.com/jglick/simple-maven-project-with-tests.git‘ } stage(‘Build‘) { // some block //step withMaven(maven: ‘M3‘) { // some block sh label: ‘‘, script: ‘mvn -Dmaven.test.failuer.ignore clean package‘ } } }
保存,并构建
2.9 构建
构建失败
修改代码
node(‘master‘) { // some block stage(‘Preparation‘) { // some block //step git ‘https://github.com/jglick/simple-maven-project-with-tests.git‘ } stage(‘Build‘) { // some block //step withMaven(maven: ‘M3‘) { // some block sh label: ‘‘, script: ‘mvn -Dmaven.test.failuer.ignore clean install package‘ } } }
再次构建成功
2.10 构建结果
