# 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
#
# 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/)
#
# 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)
#
# Profiles:
#   (default)           node-agent only — cluster visibility + hardware heartbeat
#   --profile worker    + CPU 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
#
# Examples:
#   # Agent only (register node in cluster, report hardware):
#   docker compose -f docker-compose.worker.yml up -d
#
#   # SDI capture node (1 DeckLink, no GPU worker):
#   docker compose -f docker-compose.worker.yml --profile capture up -d
#
#   # Full node (GPU worker + SDI capture):
#   docker compose -f docker-compose.worker.yml -f docker-compose.gpu.yml \
#     --profile worker --profile capture up -d
