linux 管道 pipeline,linuxea:jenkins pipeline简单使用示例(2)

jenkins pipeline简单使用示例

I. pipeline简述

Jenkins pipeline 是一套插件，支持将连续输送管道实施和整合到Jenkins。Pipeline提供了一组可扩展的工具，用于通过管道DSL为代码创建简单到复杂的传送流水线。他目前支持jenkins 2.x以上版本。pipeline是由groovy语言编写

II. pipeline使用

pipeline分为两种一种为jenkinsfile使用，一种直接在网页界面中输入脚本内容，本章节则是第二种

III. 文档参考

官方参考：https://jenkins.io/doc/book/pipeline/

语法参考：https://jenkins.io/doc/book/pipeline/syntax/

IV. 示例演示

简单的实现了php的代码发布：

1，定义了常用变量在全局的变量中

2，第一阶段代码拉取，到jenkins的目录中

3，第二阶段这里做了即将推送代码的目录的检查，是否存在，主要测试if语句

4，第三阶段检查进程是否存在(这没必要)

5，第四阶段推送代码前确认，是否发布，否则将暂停

6，第五阶段利用ansible推送代码

这里面有很多需要提前准备，比如权限问题，ansible配置等

jenkins+pipeline+gitlab+ansible快速安装配置(1)参考：点击直达

1，pipeline文件

pipeline {

agent any

environment {

def ITEMNAME = "webapp"

def DESTPATH = "/data/wwwroot"

def SRCPATH = "~/workspace/linuxea"

}

stages {

stage('代码拉取'){

steps {

echo "checkout from ${ITEMNAME}"

git url: 'git@git.ds.com:mark/maxtest.git', branch: 'master'

//git credentialsId:CRED_ID, url:params.repoUrl, branch:params.repoBranch

}

}

stage('目录检查') {

steps {

echo "检查${DESTPATH}目录是否存在"

script{

def resultUpdateshell = sh script: 'ansible webapp -m shell -a "ls -d ${DESTPATH}"'

if (resultUpdateshell == 0) {

skip = '0'

return

}

}

}

}

stage('服务检查') {

steps {

echo "检查nginx进程是否存在"

script{

def resultUpdateshell = sh script: 'ansible webapp -m shell -a "ps aux|grep nginx|grep -v grep"'

if (resultUpdateshell == 0) {

skip = '0'

return

}

}

}

}

stage('发布确认') {

steps {

input "检查完成，是否发布?"

}

}

stage('代码推送') {

steps {

echo "code sync"

sh "ansible ${ITEMNAME} -m synchronize -a 'src=${SRCPATH}/ dest=${DESTPATH}/ rsync_opts=-avz,--exclude=.git,--delete'"

}

}

}

}

2，创建item

粘贴脚本到此处保存退出

立即构建会提示是否发布，选择Proceed 即可继续

不管更新过程中还是更新出错或者更新完成都可以在logs中查看进度和结果，如下图

后台console output文件执行结果如下
