# Turnstone with external Postgres DB.
# Data lives in the named volume `turnstone_pgdata` — survives image rebuilds.
# To adopt an EXISTING Postgres install, set DATABASE_URL to point at it and
# remove the `db` service and `depends_on` blocks.
#
# Quick start:
#   docker compose up -d
#   # Then open http://localhost:8520
