# =============================================================================
# Mnemosyne — production deployment
# =============================================================================
# Four services, all from the same image:
#   app      — Django REST API + admin (gunicorn, port 8000)
#   mcp      — FastMCP server (uvicorn, port 22091)
#   worker   — Celery worker (embedding/ingest/batch queues)
#   web      — reverse proxy, public port 23090 (nginx)
#
# External services (NOT spun up here): Postgres on Portia, Neo4j on Umbriel,
# RabbitMQ on Oberon, S3/MinIO on Nyx, Memcached on its own host, embedder
# and reranker on Nyx, smtp4dev on Oberon. All reached over the internal
# 10.10.0.0/24 network.
#
# Run:
#   docker compose up -d
#   docker compose run --rm app migrate    # one-shot DB migrate
#   docker compose run --rm app setup      # Neo4j indexes + library types
# =============================================================================

services:
  # ── Static-file seeder: copies /app/staticfiles into the shared volume on
  # every `up`. Runs once and exits. Without this, the named volume is only
  # seeded the first time it's empty, so static updates between deploys
  # would not propagate to nginx.

volumes:

  # mounts this volume, populating it on first start; nginx reads from it.
  mnemosyne-static:
  # Local FileSystemStorage fallback. Production uses USE_LOCAL_STORAGE=False
  # so this is mostly empty — kept for parity with dev and for any path
  # that writes to MEDIA_ROOT directly.
