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

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

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/

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
