# 第一阶段：编译前端
FROM node:20-alpine AS frontend
WORKDIR /web
# 仅复制 package.json 以利用缓存
COPY frontend/package.json frontend/package-lock.json* ./
RUN npm install --no-audit --no-fund
COPY frontend/ ./
RUN npm run build

# 第二阶段：发布 .NET 后端
FROM mcr.microsoft.com/dotnet/sdk:8.0 AS backend
WORKDIR /src
COPY backend/*.csproj ./
RUN dotnet restore
COPY backend/ ./
RUN dotnet publish -c Release -o /app /p:UseAppHost=false

# 第三阶段：运行时镜像（Nginx + .NET）
FROM mcr.microsoft.com/dotnet/aspnet:8.0 AS runtime
WORKDIR /app
COPY --from=backend /app ./
# 把前端构建产物复制到后端的 wwwroot
