# Dragon Fork WebRTC PoC — TrueNAS deployment template.
#
# Host networking is required: WebRTC ICE needs each container-visible
# UDP socket to be reachable from the peer using the LAN (or public)
# IP advertised in SDP. Bridge + port mapping breaks ICE because
# remote candidates encode the peer-visible host:port.
#
# Copy this file to /mnt/NVME/Docker/dragonfork-webrtc-poc/
# alongside a .env like:
#
#   WHEP_PORT=45121     # TCP, the WHEP HTTP listener
#   RTP_PORT=49248      # UDP, publisher's RTP ingest port
#   STREAM_ID=test
#   PUBLIC_IP=10.0.0.25 # LAN IP; rewrites ICE host candidates via NAT1To1.
#                        Set to your public IP when exposing externally.
#
# Then:
#   docker compose up -d --build
