Jenkins pipeline 使用agent docker编译构建

Jenkins 使用agent docker构建pipeline

　　此处用于记录，使用jenkins pipeline构建时，使用docker启动一个agent来构建编译环境。

// 需要在jenkins的Credentials设置中配置jenkins-harbor-creds、jenkins-k8s-config参数
pipeline {
    agent any
    environment {
        HARBOR_CREDS = credentials('jenkins-harbor-creds')
        K8S_CONFIG = credentials('jenkins-k8s-config')
        SONAR_HOME = tool('sonar-scanner')
        HARBOR_HOST= credentials('harbor-host')
        // git tag 需要使用x.x.x的形式
        GIT_TAG = sh(returnStdout: true,script: "#!/bin/bash \n if [[ `git describe --tags --always` =~ '-g' ]] ;then echo 'latest' ; elif [[ `git describe --tags --always` =~ '.' ]] ; then echo `git describe --tags --always` ; else echo 'latest' ;fi").trim()
    }
