CICD—Jenkins Gitlab自动化打包前端到K8S

温馨提示：环境搭建：Jenkins、gitlab、两者之间打通；钉钉机器人创建都已省略自己问度娘文章很多（整个打包过程全自动，开发人员只需要提交代码就可以自动构建）。

架构图：

效果图：

构建完成发布消息到钉钉

第一步、安装依赖环境 （kubectl、nodejs）

curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -

sudo apt-get install -y nodejs

第二步、配置Jenkins任务

触发器

流水线配置

gitlab配置：

gitlab钩子设置

第三步：编写构建脚本，所有分支、环境都用一套脚本打包简化重复工作。

#!groovy

pipeline {

    //代理

agent any

    //环境变量

    environment {

        REPOSITORY="git@xxxxxxxxxxxxxxxxxxxxxxxx.git"                           //git地址
