# Wild Dragon MAM — Worker Node Stack
# ─────────────────────────────────────
# Deploy on any machine you want to join the cluster as a worker.
# The primary stack (mam-api, db, redis) continues running on TrueNAS.
#
# Required env vars (set in .env.worker or export before running):
#   MAM_API_URL   URL of the primary MAM API  e.g. http://10.0.0.25:47432
#   NODE_TOKEN    Bearer token from the primary's Tokens page
#   NODE_IP       Host LAN IP to report (set by onboard-node.sh)
#
# Optional hardware overrides (if Docker can't see /dev directly):
#   GPU_COUNT     Number of NVIDIA GPUs on this node  (default: auto-detect from /dev/nvidia*)
#   BMD_COUNT     Number of Blackmagic DeckLink cards (default: auto-detect from /dev/blackmagic/)
#   BMD_MODEL     Marketed card name (e.g. "DeckLink Duo 2") — drives the port-diagram UI
#
# Optional env vars (needed only if starting the worker or capture profiles):
#   REDIS_URL, DATABASE_URL, S3_ENDPOINT, S3_BUCKET, S3_ACCESS_KEY, S3_SECRET_KEY
#   BMD_DEVICE_0  DeckLink device path (default: /dev/blackmagic/dv0)
#   BMD_DEVICE_1  DeckLink device path (default: /dev/blackmagic/dv1)
#   LIVE_DIR      Host path for HLS live segments (default: /mnt/NVME/MAM/wild-dragon-live)
#
# Profiles:
#   (default)           node-agent only — cluster visibility + hardware heartbeat
#   --profile worker    + CPU/GPU job worker (proxy generation, transcoding)
#   --profile capture   + SDI capture service (requires Blackmagic DeckLink card)
#
# To enable GPU transcoding, also apply docker-compose.gpu.yml:
#   docker compose -f docker-compose.worker.yml -f docker-compose.gpu.yml --profile worker up -d
#
# NOTE: The node-agent mounts /var/run/docker.sock to spawn on-demand SDI
# capture sidecars when the primary mam-api routes a recorder to this node.
# Build the capture image before first use:
#   docker compose -f docker-compose.worker.yml build capture

services:

  # node-agent runs in host network mode so it can see the real host
  # interfaces, GPU devices and DeckLink cards without bridging tricks.
  # The reported IP / hostname will be the host's, not the container's.
