# Host nginx config for staging server: /etc/nginx/sites-available/05-xiaoxia-cms
# Xiaoxia CMS - cms.xiaoxiajianji.com
# 
# 注意：此文件是宿主机 nginx 配置的备份/参考，不是 Docker 容器内的 nginx。
# Docker 容器内的 nginx 配置见 nginx-staging.conf。

# GPU relay 路由说明：
# P4000 编码完成后通过 http://100.69.73.60:8092/api/v1/internal/gpu-relay/{key} PUT 上传
# Worker 容器通过 http://xiaoxia-api-staging:8000/api/v1/internal/gpu-relay/{key} GET 下载
# 8092 端口由 CMS 宿主机 nginx 承载，GPU relay 路由通过最长前缀匹配优先代理到 staging API (8000)
