# Optional: one-command local Postgres + pgvector for development.
#
# If you already have a Postgres + pgvector instance running somewhere
# (e.g. a managed/remote server you used with the original project), you
# do NOT need this - just point backend/.env at it instead.
#
# Ollama is intentionally NOT included here: install it natively on the
# host (see docs) so it can use your CPU efficiently without an extra
# container layer, and so `ollama pull` model files persist outside Docker.
#
# Usage:
#   docker compose up -d
#   # then in backend/.env: DB_HOST=localhost, DB_PORT=5432, DB_NAME=pgvector,
#   # DB_USER=postgres, DB_PASSWORD=<the value you set below>
services:
  postgres:
    image: pgvector/pgvector:pg16
    container_name: catalog_rag_postgres
    restart: unless-stopped
    environment:
      POSTGRES_DB: pgvector
      POSTGRES_USER: postgres
      # Override this in a local .env file next to this compose file
      # (docker compose auto-loads .env) or export POSTGRES_PASSWORD
      # before running `docker compose up`. Do not commit a real value.
