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

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
