# 升级基础镜像到稳定的 Node 22，防止 Prisma 7.x 报引擎不兼容错误

# 阶段 1: 安装所有依赖
# ==========================================
FROM base AS deps
COPY package*.json ./
# 如果本地有 prisma 目录，一并复制，确保编译时生成正确的 Client
COPY prisma ./prisma/
RUN npm ci

# 阶段 2: 构建应用
# ==========================================

# 仅仅在构建期生成 Prisma Client 代码，【删除】db push 动作，建表必须延后到运行时

# 1. 复制 standalone 构建输出
COPY --from=builder /app/.next/standalone ./
COPY --from=builder /app/.next/static ./.next/static
COPY --from=builder /app/public ./public

# 2. 【彻底修复】：完整复制 Prisma CLI 运行所需的三个核心物理目录和软链接
COPY --from=builder /app/prisma ./prisma
COPY --from=builder /app/node_modules/prisma ./node_modules/prisma
COPY --from=builder /app/node_modules/@prisma ./node_modules/@prisma
COPY --from=builder /app/node_modules/.bin/prisma ./node_modules/.bin/prisma

# 3. 创建数据挂载目录并修正权限
RUN mkdir -p /app/data && chown -R nextjs:nodejs /app/data /app/prisma
