# PostgreSQL image/data overrides.
# Default compose now uses postgres:18.3-alpine with PGDATA=/var/lib/postgresql/18/docker.
# To reuse an existing 1Panel PostgreSQL 18 data directory, stop the old DB first,
# then point POSTGRES_DATA_SOURCE to the host directory that contains PG_VERSION.
# Example for 1Panel PostgreSQL with:
#   host mount: /opt/1panel/apps/postgresql/postgresql/data -> /var/lib/postgresql
#   PGDATA:     /var/lib/postgresql/18/docker
# use:
# POSTGRES_IMAGE=postgres:18.3-alpine
# POSTGRES_DATA_SOURCE=/opt/1panel/apps/postgresql/postgresql/data/18/docker
# POSTGRES_PGDATA=/var/lib/postgresql/18/docker
# POSTGRES_USER=user_from_old_container
# POSTGRES_PASSWORD=password_from_old_container
# POSTGRES_DB=quantdinger

# Global image source switch for infrastructure images
# Leave empty for official Docker Hub:
# IMAGE_PREFIX=
# REDIS_IMAGE=redis:8-alpine
#
# 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.
# - For slow `docker pull` of base images, use IMAGE_PREFIX or Docker
#   Desktop → Settings → Docker Engine → registry-mirrors (e.g. daocloud).

# Backend Dockerfile region switch (used by docker-compose.yml build):
#   global  = use Debian/PyPI official sources directly, skip Aliyun entirely (default)
#   cn      = use Aliyun apt/PyPI mirrors with fallback to official
# BUILD_REGION=global

# Backend Python base image override for local builds.
# docker-compose.yml defaults to docker.1ms.run/library/python:3.12-slim-bookworm
# to reduce first-install failures caused by Docker Hub auth/base-image pulls.
# Set this only when you want a different source.
# PYTHON_BASE_IMAGE=python:3.12-slim-bookworm
# PYTHON_BASE_IMAGE=docker.xuanyuan.me/library/python:3.12-slim-bookworm

# Recommended install paths:
# - Regular users: use docker-compose.ghcr.yml. It pulls prebuilt backend,
#   frontend, and mobile images and does not build from python:3.12 locally.
# - Developers/local source edits: use docker-compose.yml and set
#   PYTHON_BASE_IMAGE only if Docker Hub is slow.

# ----- Image tags (consumed by both docker-compose.yml and docker-compose.ghcr.yml) -----
#
# Resolution order (highest precedence first):
#   BACKEND_TAG / FRONTEND_TAG  →  IMAGE_TAG  →  compose file default (latest)
#
# Default: compose pulls ghcr.io/.../quantdinger-*:latest on every `up` (pull_policy: always).
# Uncomment to pin a release (GHCR semver tags omit the leading "v", e.g. v5.0.1 → 5.0.1):
# IMAGE_TAG=5.0.1
#
# Advanced — decouple sides (e.g. frontend hotfix against stable backend):
# FRONTEND_TAG=5.0.2
# BACKEND_TAG=5.0.1
#
# Override the GHCR image paths (e.g. for forks):
# BACKEND_IMAGE=ghcr.io/openbyteinc/quantdinger-backend
# FRONTEND_IMAGE=ghcr.io/openbyteinc/quantdinger-frontend
