Jenkins入门(二)声明式流水线Jenkins Pipeline
2020-11-06 22:33:00 【超_Charles】
1. Jenkins Pipeline 基本概念
流水线是用户定义的一个CD流水线模型 。流水线的代码定义了整个的构建过程, 他通常包括构建, 测试和交付应用程序的阶段 。 Jenkins Pipeline
(或简称为"Pipeline")是一套插件,将持续交付的实现和实施集成到Jenkins中。 持续交付Pipeline
自动化的表达了这样一种流程:将基于版本控制管理的软件持续的交付。 Jenkins Pipeline 的定义通常被写入到一个Jenkinsfile
文本文件中,该文件可以被放入项目的源代码控制库中。
2.Jenkinsfile 基础语法
pipeline { // 特定语法,pipeline 块定义了整个流水线中完成的所有的工作
agent any // agent为整个流水线分配一个执行器 (在节点上)和工作区
stages { // 所有流程(状态)的外层块,仅有一个
stage('Build') { // 每个stage为一流程,定义名称
steps { // 步骤块,内部包含具体操作
sh 'make' // sh操作,其引号间的文字会当成shell直接执行
}
}
stage('Test'){
steps {
sh 'make check'
junit 'reports/**/*.xml' //junit使用匹配的定义测试xml进行单元测试
}
}
stage('Deploy') {
steps {
sh 'make publish'
}
}
}
}
3.创建 Hello World 流水线
- 登录
Jenkins
,新建任务(New Item),选择流水线
,输入工程名称Hello Pipeline
,确定。 - 填写描述,勾选
参数化构建过程(This project is parameterized)
。 - 添加参数,选择
字符参数(String parameter)
,并设置这个字符串参数(名称,默认值,描述),这样我们在Jenkinsfile中就可以取到这个值了。 - 向下滑动到
流水线
,定义选择Pipeline script
,脚本输入如下内容,然后保存。
pipeline {
agent any
environment { //环境变量
GREETING="Hello"
}
stages{
stage('打招呼') {
steps{
sh 'echo "$GREETING $TITLE"'
}
}
}
post { //构建完成后置操作
aborted { //如果构建中断,则执行
echo '构建被中止!'
}
success { //构建成功执行
echo '构建成功!'
}
failure { //构建失败执行
echo '构建失败!'
}
}
}
-
点击
Build with Parameters(参数化构建)
,然后开始构建
。 -
构建完成输出界面:
-
把鼠标放在打招呼下边的绿色框上,点出现的
logs
,可以看到输出了预期的值。 -
找到左下角的
Build History(构建历史)
的构建版本号,如当前是#1
,点进去,选择Console Output
查看详细的执行日志。
# 成功Console Output
