/**
|

* OfferPie Web 前端蓝绿部署流水线
|
||
*
|
||
* 工作目录说明：
|
||
* - Jenkins 会自动为每个项目创建独立的工作空间：/var/jenkins_home/workspace/<项目名>/
|
||
* - docker-compose.yml、Dockerfile、nginx.conf 都在项目根目录，直接执行即可
|
||
* - nginx.conf 首次部署时 docker cp 进 nginx 容器
|
||
*
|
||
* 内层 Nginx 职责：
|
||
* - 蓝绿切换（前端静态文件 serve）
|
||
* - /api/ 代理到 Java 后端（10202）
|
||
* - /ai-api/ 代理到 Python AI（10502），rewrite 去掉前缀
