# Passive UDP ingestor deployment for a Raspberry Pi 5 (arm64).
#
# Runs the ingestor in TRANSPORT=udp mode. It reads the same .env as the
# standard deployment (API_TOKEN etc. are untouched) and only swaps the node
# connection from single-client serial/TCP to passive LAN multicast.
#
# Prerequisites on the Pi (once):
#   1. Get the source onto the Pi (arm64 images are built natively — no QEMU).
#   2. Build the arm64 image from it:
#        docker build -f data/Dockerfile -t potato-mesh-ingestor:udp .
#   3. Copy this file to your compose.yml and add PRIMARY_CHANNEL_NAME +
#      INGESTOR_NODE_ID to .env.
#   4. docker compose up -d
#
# `network_mode: host` is REQUIRED — multicast (224.0.0.69) cannot reach a
# bridged container.
