# =============================================================================
# docker-compose.yml — CRM System v1.0 (local testing with PostgreSQL)
#
# Use this file to run a full Postgres + crm-app stack locally, e.g. for
# smoke-testing the Docker image or running the backend against a real
# PostgreSQL instance before deploying to Coolify.
#
# Production deploys in Coolify use COOLIFY_SETUP.md (single-container app +
# a Coolify-managed Postgres database), NOT this file.
#
# Usage:
#   cp .env.docker.example .env.docker
#   $EDITOR .env.docker          # fill AUTH_SECRET, POSTGRES_PASSWORD, ...
#   docker compose --env-file .env.docker up --build
#   curl http://localhost:8000/health
