## 第一阶段 ====> Nodejs打包编译输出前端资源
FROM node:18-alpine AS build-nodejs

## 工作目录存放程序源码
WORKDIR /frontend

## 复制实际需要的文件到工作目录
COPY ./frontend ./

RUN npm config set registry https://registry.npmmirror.com
RUN cd /frontend && npm install && npm run build

## 第二阶段 ====> GO打包编译输出后端程序
FROM golang:alpine AS build-go
