# Dockerfile

# 使用 Node 官方镜像
FROM node:18-alpine

# 设置工作目录
WORKDIR /app

# 拷贝后端文件（假设 server.js 和 package.json 都在当前目录）
COPY backend/server.js package.json ./

# 安装依赖和 pm2
RUN npm config set registry https://registry.npmmirror.com && \
    npm install --no-audit --no-fund && \
    npm install -g pm2 --no-audit --no-fund


# 开放端口（如果后端监听 3600）
EXPOSE 3600

# 使用 pm2 启动
CMD ["pm2-runtime", "server.js"]
