DEVOPS技术实践_03：Jenkins自动构建

一、提交代码自动构建

当开发人员在gitlab提交代码后，会自动触发jenkin构建

点击项目---->点击diy_maven-TEST----->点击配置--->构建触发器---->根据需求选择触发器

1.1 安装gitlab hook插件

系统管理----->选择插件管理-------->查找gitlab-------->选择直接安装

安装完成

1.2 配置gitlab仓库

点击项目---->点击diy_maven-TEST----->点击配置--->构建触发器

发现没有变化，需要重启jenkins

点击是，jenkins重启

发现没有，升级jenkins

关机

然后重新使用Java启动war包就可以了

继续安装gitlab的其他插件尝试

点击项目---->点击diy_maven-TEST----->点击配置--->构建触发器

保存这个地址

http://172.25.254.130:9000/project/diy-maven_TEST

1.3 gitlab设置

选择仓库设置setting

复制url到此处

1.4 点击添加

gitlab 10.6 版本以后为了安全，不允许向本地网络发送webhook请求，如果想向本地网络发送webhook请求，则需要使用管理员帐号登录，默认管理员帐号是admin@example.com，密码就是你gitlab搭建好之后第一次输入的密码，登录之后， 点击Configure Gitlab ，如下图所示

即可进入Admin area，在Admin area中，在settings标签下面，找到OutBound Request，勾选上Allow requests to the local network from hooks and services ，保存更改即可解决问题

成功

1.5 点击测试test

得到200成功

验证

二 、 Jenkins-pipeline自动化配置

https://jenkins.io/doc/book/pipeline/

2.1 安装pipeline插件

2.2 gitlab创建一个group

2.3 在group创建一个项目

NEW Project

2.4 Command line instructions

Git global setup
git config --global user.name "tester admin"
git config --global user.email "joy04007@gmail.com"
 
Create a new repository
git clone http://172.25.254.131/devops/jenkins.git
cd jenkins
touch README.md
git add README.md
git commit -m "add README"
git push -u origin master
 
Existing folder
cd existing_folder
git init
git remote add origin http://172.25.254.131/devops/jenkins.git
git add .
git commit -m "Initial commit"
git push -u origin master
 
Existing Git repository
cd existing_repo
git remote rename origin old-origin
git remote add origin http://172.25.254.131/devops/jenkins.git
git push -u origin --all
git push -u origin --tags

2.5 新加一个文件提交

NEW File:java.jenkinsfile

2.6 jenkins创建任务

jenkins创建一个流水线项目,然后pipeline设置

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
      if (isUnix()) {
         sh "'${mvnHome}/bin/mvn' -Dmaven.test.failure.ignore clean package"
      } else {
         bat(/"${mvnHome}\bin\mvn" -Dmaven.test.failure.ignore clean package/)
      }
   }
   stage('Results') {
      junit '**/target/surefire-reports/TEST-*.xml'
      archiveArtifacts 'target/*.jar'
   }
}

2.7 添加一个key

2.8 点击构建

成功！！！

2.9 写一个完整的pipeline

使用pipeline模板代码

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
      if (isUnix()) {
         sh "'${mvnHome}/bin/mvn' -Dmaven.test.failure.ignore clean package"
      } else {
         bat(/"${mvnHome}\bin\mvn" -Dmaven.test.failure.ignore clean package/)
      }
   }
   stage('Results') {
      junit '**/target/surefire-reports/TEST-*.xml'
      archiveArtifacts 'target/*.jar'
   }
}

newfile

node {
   def mvnHome
   stage('Checkout') { // for display purposes
       println('checkcode')
   }
   stage('Build') {
      println('Build')
   }
   stage('Test') {
      println('test')
   }
   stage('Deploy'){
       println('Deploy')
   }
   stage('CodeScan'){
       println('code')
   }
}

Jenkins在任务配置重新配置脚本路径
