# ============================================
# 农产品直销平台 - 前端 Dockerfile
# 多阶段构建: Node编译 → Nginx部署
# ============================================

# ---------- 第一阶段：Node构建 ----------
FROM node:18-alpine AS builder
WORKDIR /app

# 配置npm镜像（加速依赖下载）
RUN npm config set registry https://registry.npmmirror.com

# 先复制package文件，利用Docker缓存层
COPY package*.json ./
RUN npm install

# 复制源代码并构建
COPY . .
RUN npm run build

# ---------- 第二阶段：Nginx部署 ----------
FROM nginx:1.25-alpine

# 设置时区
RUN ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \
    echo "Asia/Shanghai" > /etc/timezone

# 复制自定义Nginx配置
COPY nginx.conf /etc/nginx/conf.d/default.conf

# 从构建阶段复制静态文件
COPY --from=builder /app/dist /usr/share/nginx/html
