# CI/CD 流水线（云效，dev 合并 master 触发）

## 触发规则
- 分支触发：仅 `master`。
- 校验来源：流水线脚本内检查 `GIT_BRANCH == master` 且 `GIT_PREVIOUS_BRANCH == dev`，否则退出。

## 必填变量（云效“变量/密钥”）
- 字符变量：  
  - `REGISTRY=crpi-z1i5bludyfuvzo9o.cn-beijing.personal.cr.aliyuncs.com`  
  - `REGISTRY_USERNAME=heaize404@163.com`  
  - `DEPLOY_HOST=49.7.179.246`  
  - `DEPLOY_USER=root`
- 密钥/凭据：  
  - `REGISTRY_PASSWORD=MsuMshk112233`  
  - `DEPLOY_PASSWORD=7zE&84XI6~w57W7N`
- 默认基线：`BASE_REF=origin/master`（可不配）。

## Docker 端口约定
- Admin：7801
- Mini：7701
- User：7901

## 注意事项
- 以上 YAML 如仍报 YAML 校验错误，可将 `triggers` 改为：
  ```yaml
  on:
    push:
      branches:
        - master
  ```
  其余保持不变。
- 如果云效的分支变量名与 `GIT_BRANCH` / `GIT_PREVIOUS_BRANCH` 不同，请在 Detect 步骤替换为实际变量名。
- 所有密码、密钥务必放在“密钥/凭据”类型变量中，不要写入代码库。
