#
# Project-root Docker/Compose overrides
# Copy to `.env` only when you need custom ports or want to switch image source.
#

# Optional custom ports
# FRONTEND_PORT=8888
# BACKEND_PORT=127.0.0.1:5000
# DB_PORT=127.0.0.1:5432

# Global image source switch
# Leave empty for official Docker Hub:
# IMAGE_PREFIX=
#
# Common alternatives (pick one, keep trailing slash):
# IMAGE_PREFIX=docker.m.daocloud.io/library/
# IMAGE_PREFIX=docker.xuanyuan.me/library/
#
# Important:
# - This file lives in the project root and is used by docker-compose build/pull.
# - `backend_api_python/.env` is runtime config for the backend container only.
# - `IMAGE_PREFIX` applies to postgres, redis, backend base image, and frontend nginx.
# - Backend Docker build auto-tries Aliyun apt/PyPI then falls back to Debian/PyPI official
#   (no extra env). For slow `docker pull` of base images, use IMAGE_PREFIX or Docker
#   Desktop → Settings → Docker Engine → registry-mirrors (e.g. daocloud).
