我正在构建一个Dockerfile用于部署基于 monorepo 节点的服务器，该服务器基于packages/server并依赖于其他一些包。

生成的图像为 750Mb，原因是大的 node_modules 文件夹。由于这是一个生产编译，我想：

  • 完全删除 node_modules
  • 基本上跑node packages/server/build/server.js

通常我会用yarn workspace server start:prod这个。

我有两个问题：

  1. 启动节点服务器包的最佳方法是什么Dockerfile？为了让所有相关的路径关系正常工作。
  2. 当我删除 node_modules 时，如何确保运行构建不会爆炸（当我这样做时会发生这种情况：它尝试从 node_modules 加载文件）

这是当前的：
