# 阶段1: 构建阶段
FROM node:22.14.0-slim AS builder

WORKDIR /app

RUN npm install -g pnpm

# 2. 复制依赖文件（优先层）
COPY package.json pnpm-lock.yaml ./
# RUN npm ci --legacy-peer-deps
RUN pnpm install

# 3. 复制源码并构建
COPY . .
RUN pnpm run build

# 阶段2: 生产运行阶段
FROM node:22.14.0-slim

WORKDIR /app

# 1. 生产环境配置

ENV PORT 3000

# 2. 从构建阶段复制文件
# COPY --from=builder /app/package.json .
# COPY --from=builder /app/pnpm-lock.yaml .
# COPY --from=builder /app/node_modules ./node_modules
# COPY --from=builder /app/next ./next

# 3. 如果是自定义服务器需要复制
# COPY --from=builder /app/server ./server

# 4. 非root用户
# RUN groupadd -g 1001 nodejs && \
#     useradd -u 1001 -g nodejs -d /app nodejs && \
#     chown -R nodejs:nodejs /app

EXPOSE 3000

# 关键修正点：使用 npm start 启动
CMD ["pnpm", "run", "start"]
