docker-compose.yml

# Full stack: API + persistent Chroma storage + Streamlit UI (+ one-off seeder).
#
# Chroma runs embedded in the API process (file-based, zero infra — the
# project's fixed storage choice); ./data is bind-mounted so the index survives
# restarts and seeding on the host writes the same index the container serves.
#
# Quickstart (zero manual steps beyond an API key in .env):
#   cp .env.example .env                # set OPENAI_API_KEY
#   docker compose up -d --build        # API :8000, UI :8501
#   docker compose run --rm seed        # index the sample corpus
#   open http://localhost:8501          # or curl the API (see README)
