# AWOOOI API - Production Dockerfile
# Phase 6.4i: 支援 monorepo 本地 packages (lewooogo-brain, lewooogo-data)
#
# 使用方式 (從 monorepo 根目錄):
#   docker build -f apps/api/Dockerfile -t awoooi-api:v1.0.0 .
#
# 注意: 必須從 monorepo 根目錄執行，否則無法存取 packages/

# Install uv (固定版本，禁止 :latest)

# Phase 6.4i: 複製本地 packages 到 Docker context
# 順序重要: 先複製 packages，再複製 api (利用 Docker layer cache)
COPY packages/lewooogo-data/ /packages/lewooogo-data/
COPY packages/lewooogo-brain/ /packages/lewooogo-brain/

# 複製 API 依賴文件 (pyproject.toml 需要 README.md)
COPY apps/api/pyproject.toml apps/api/README.md ./

# 複製 src 目錄 (hatchling build 需要)
COPY apps/api/src/ ./src/

# 安裝本地 packages 與 API 依賴 (合併 RUN 減少 layer)
# 注意: `uv pip install .` 從 pyproject.toml 安裝依賴
