  1 +# LiveKit Server PoC
  2 +
  3 +最小可用的 LiveKit Server 自部署验证环境，用于零期 PoC。
  4 +
  5 +## 启动
  6 +
  7 +```bash
  8 +cd tools/livekit-poc
  9 +docker compose up -d
  10 +bash verify.sh
  11 +```
  12 +
  13 +## 端口
  14 +
  15 +- 7880：HTTP / WebSocket 信令；
  16 +- 7881：WebRTC TCP fallback；
  17 +- 7882/UDP：WebRTC 媒体；
  18 +- macOS / Windows：当前 `docker-compose.yml` 走端口映射模式，webhook URL 用 `host.docker.internal:48080` 让容器访问到宿主机 yudao 后端；
  19 +- macOS 上 host network（`network_mode: host`）需要 Docker Desktop 4.34+ 并在 Settings → Resources → Network 勾选「Enable host networking」，老版本静默失败（容器跑得起来但端口完全不通）；
  20 +- Linux：可以把 `docker-compose.yml` 改成 `network_mode: host` + 删 `ports:` 段，并把 `livekit.yaml` 的 webhook URL 改为 `http://127.0.0.1:48080/admin-api/im/livekit/webhook`。
  21 +
  22 +## 凭据 (仅 PoC，勿用于生产)
  23 +
  24 +- `LIVEKIT_KEYS=devkey: secret-poc-key-min-32-chars-required-here`
  25 +- API Key：`devkey`
  26 +- API Secret：`secret-poc-key-min-32-chars-required-here`
  27 +
  28 +生产环境必须改用强随机 secret，并通过 `--config /etc/livekit.yaml` 加载。
  29 +
  30 +## 浏览器联调
  31 +
  32 +`verify.sh` 跑完会输出一个 `meet.livekit.io` 链接，用两个浏览器（或两台机器）打开同一链接即可看到对方画面。
