# 小程序 RTMP ↔ LiveKit 网关试验环境（默认关闭，勿用于生产）
# 与上级目录的 LiveKit-only PoC 二选一：两者都占用 7880 等端口，启动本环境前先 docker compose -f ../docker-compose.yml down
#
# 全部服务使用 host 网络：Ingress / Egress 作为 WebRTC 客户端连接 LiveKit 广播的 node_ip（127.0.0.1），
# 端口映射模式下容器内的 127.0.0.1 不是 LiveKit；macOS 需 Docker Desktop 4.34+ 并开启 Settings → Resources → Network → Enable host networking
#
# 凭据通过同目录 .env 提供（参考 .env.example），必须与后端 yudao.im.rtc.api-key / api-secret 一致
