# AI Video Assistant 平台 —— docker compose
#
# 核心服务(默认起):postgres + api + ui
#   docker compose up -d postgres api      # 后端 + 库
#   docker compose up -d                   # 再带上前端 ui → http://localhost:3030
#
# 语音对话调试(参考 dograh quick start 的直连方案):
#   docker compose up -d && make db-seed   # 首次需灌种子(凭证+助手)
#   浏览器开 http://localhost:3030 → 助手 → 语音预览
#   (localhost 是 secure context,麦克风可用;WebRTC 媒体直连 api,WS 信令走 :8000)
#
# 可选服务(用 profile 推迟到需要时):
#   docker compose --profile data up -d    # + redis / rustfs(后台任务、S3 录音存储)
#   docker compose --profile remote up -d  # + coturn(WebRTC 公网 TURN 穿透)
