脚本判断代码是否修改过，修改则重启对应的docker容器_jenkins判断目录有没有更改-优快云博客

本文链接：https://blog.youkuaiyun.com/qq_40460909/article/details/87272015

本文介绍了一种自动化部署策略，通过使用shell脚本和find命令检查特定目录下的文件修改情况，仅重启那些源代码有变动的Docker容器，如ppay_dist、eureka-server等，有效提高了开发效率并减少了不必要的资源消耗。

一，大概流程

开发提交 git > jenkins > mvn > 脚本

#利用 find 查找对应目录是否有修改的文件，-name 所有文件 -mmin -1 一分钟。

#这样开发提交代码，只重新启动修改过代码的容器

#!/bin/bash
#ppay_dist，判断dist目录是否改动，如有，更新dist模块，重启dist容器
dist=`find /var/lib/jenkins/workspace/ppay/dist/src/ -name '*.*' -mmin -1 | wc -l`

#ppay_eureka-server，判断eureka-server目录是否改动，如有，更新eureka-server模块，重启eureka-server容器
