jenkins持续集成go应用

上文讲到使用supervisor管理我们的终端应用，这次讲一下使用jenkins持续集成

下面分别讲一下pipeline里每一个段落的含义

agent any   使用任意节点构建

parameters  模块使用参数化构建

environment 脚本全局变量

options     脚本定义参数，超时时间等

stage       每个步骤

checkout    拉取代码命令

when        当全局变量environment的value期待值符合的时候执行steps

post　　     结束后执行，always代表无论项目是否执行成功都要执行模块里的内容。常用的还有changed，failure，success，unstable

其他地方大多数使用了ansible和shell命令，比如ansible ${ip} -m shell -a "supervisorctl restart beepkg" 是使用ansible的shell 调用$ip的supervisorctl 重启beepkg队列

def createVersion() {
    // 定义一个版本号作为当次构建的版本，输出结果 20191210175842_69
    return new Date().format('yyyyMMddHHmmss') + "_${env.BUILD_ID}"
}

pipeline{
    agent any
    parameters {
        gitParameter branch: '', branchFilter: '.*', defaultValue: 'master', description: '选择代码分支', name: 'branch', quickFilterEnabled: false, selectedValue: 'NONE', sortMode: 'NONE', tagFilter: '*', type: 'PT_BRANCH'

    }

            steps{
                deleteDir()
                checkout([$class: 'GitSCM', branches: [[name: '$branch']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: '9df82ae3-5563-4d32-808b-00e8aa9ae26c', url: 'git@192.168.80.13:wuzh/cups-api.git']]])
            }    
        }
        stage('打包应用'){
            options {
                timeout(time: 4, unit: 'MINUTES') 
            }
            steps{

            }
        }
        stage('备份服务器文件'){
            when {

                value: 'yes'

        stage('重启supervisor队列'){
            steps{

            }
        }
        stage('生成日志'){
            steps{
                sh label: '', script: '''today=`date "+%Y_%m_%d"`
                now=`date "+%Y_%m_%d_%H_%M_%S"`
                echo "时间: $now" >> /root/update_log/$today
                echo "开发者: $developer" >> /root/update_log/$today
                echo "git地址: git@192.168.80.13:wuzh/cups-api.git" >> /root/update_log/$today
                echo "分支名字: $branch" >> /root/update_log/$today
                echo "更新日志: $record" >> /root/update_log/$today
                echo -e \'-----------------------------------\\n\' >> /root/update_log/$today'''
            }
        }
    }
    post('send mail'){
        always{
            emailext(
                subject: '构建通知：${PROJECT_NAME} - Build # ${BUILD_NUMBER} -${BUILD_STATUS}!',
                body: '${FILE,path="/root/script/email.html"}',
                to: 'guoyabin@96199.com.cn')
        }
    }
}

执行效果如下：
