如何运行开发和生产nestjs应用程序docker docker compose

Question

我是docker的新手，我正在尝试用我的api的开发和生产版本构建一个容器。

如果我运行命令"；docker compose-up dev"；一切都很好，但当我运行生产命令"；docker组合产品"；我得到以下错误：

我从错误中了解到的是，它没有复制或创建包含必要文件的目录，但我不确定。

This is my Dockerfile:
```

Can anyone help me with this error? Thanks in advance

Answer 1

问题出现在package.json中命令npm run start:prod指向dist/main，而它应该指向dist/src/main这都是

Answer 2

您在上一个构建阶段没有指定WORKDIR /app，所有文件都被复制到root。
