OJ2/docker/compose.school.yml

# 机房。**这里没有数据库** —— 连的是服务器那台的 5445（见 compose.debian.yml）。
#
#   docker compose -f docker/compose.school.yml --env-file docker/.env.school up -d --build
#
# 两个站点共用一个库，但各有各的 Redis、判题沙箱和后端。这意味着：
#
# - 判题队列是每站独立的（BullMQ 在本地 Redis 上），学生在哪边提交就在哪边判，
#   和旧后端的 Dramatiq 拓扑一致；
# - WebSocket 推送也走本地 Redis pub/sub，所以只推得到连在**本站**的学生。
#   旧后端的 Channels 也是这样，不是回归；
# - **切换那天两边都要切。** 只切一边的话，另一边的旧后端仍在读写同一个库，
#   而库结构已经按新后端迁过了。
#
# ⚠️ `DATA_DIR` 默认值 `../data` 解析出来是 **`OJ2/data`**，不是机房部署目录的 `data/`。
# 测试点（`data/backend/test_case`）和题面图片（`data/backend/public/upload`）都在旧目录里，
# 不设 `DATA_DIR` 就会挂一堆空目录上去：判题全错、图片 404。**沿用旧数据必须设它。**
