# HowToCook API 镜像(构建上下文 = 本仓库根目录)
# docker build -t howtocook-api .
# 菜谱内容在构建期完整克隆(保留 .git 以提取作者 / 编写时间元数据),可用构建参数覆盖:
# docker build --build-arg CONTENT_REPO=https://github.com/Anduin2017/HowToCook.git \
# --build-arg CONTENT_REF=master -t howtocook-api .
FROM node:22-alpine
# scanner 启动时通过 git log 提取作者 / 编写时间元数据(缺失时回退文件时间戳)
RUN apk add --no-cache git
ARG CONTENT_REPO=https://github.com/Anduin2017/HowToCook.git
ARG CONTENT_REF=master
# 容器内必须监听 0.0.0.0,否则端口映射不通;CONTENT_DIR 指向构建期克隆的内容目录

COPY package.json package-lock.json ./
RUN npm ci --omit=dev

COPY src ./src
# 菜谱内容(不使用 --depth,完整历史才能正确提取每道菜的首位提交作者与时间)
