Jenkins前端项目持续部署

2018-08-28  本文已影响2630人  趁你还年轻233

前后端分离的开发模式下，往往前端只需将一个包含js，html，css以及其他静态资源的dist目录发给后端。

最直观的就是vue-cli，create-react-app，自定义脚手架中的npm run build命令，本质上，是webpack，gulp等打包工具去做了编译打包等等工作，最终会生成一个dist目录，它是我们唯一需要提供给后端的内容，

如果代码无bug且只发一次版本（有这么皮的项目吗？），上面这样的方式完全ok。但是如果需要频繁更新版本，那么就需要频繁 打包 发包 接包 部署，这对于前后端来说，都是一个很低效的事情。

因此我们需要将低效的手动式部署，升级为更加先进的工程化的持续部署。

Jenkins就很好的可以做这样的事情，而且公司项目正在正常使用。

下面我将在Github新建一个repo，并且使用vue-cli初始化一个前端项目，最后结合Jenkins做一次前端CD。

local：vue项目 Jenkins服务器
remote：github repo

新建repo

项目地址：https://github.com/FrankKai/frontend-jenkins-cd

初始化项目

vue create demo

下载并安装Jenkins

  1. Download Jenkins.

  2. Open up a terminal in the download directory.

  3. Run java -jar jenkins.war --httpPort=8080.

  4. Browse to http://localhost:8080.

  5. Follow the instructions to complete the installation.

CD配置

触发远程构建 (例如，使用脚本)

构建环境
Delete workspace before build starts
Abort the build if it’s stuck

构建
Execute shell

从日志中我们其实可以发现，Jenkins主要做了2件事：

用一句话总结，其实就是jenkins构建，ssh更新。

茅塞顿开的感觉真好！
