As a user I would to be able to provide a path to my server entry point (server.js)

[thescientist13]

This would allow any user to provide a custom path to their own server's entry point location.

COPY ./server.js ./

CMD ["babel-node", "--presets=@babel/preset-react,@babel/preset-env", "server.js"]

Default value should be server.js

[thescientist13]

It should be emphasized that the location of this file will be relative to the src/ directory in the container as such

app/
  server.js
  src/
  static/

So paths in server.js should take that into consideration, e.g.

import Express from 'express';
import React from 'react';
import { createStore } from 'redux';
import { Provider } from 'react-redux';
import counterApp from './src/reducers'; // this is a path that needs to reference _src/_
import App from './src/containers/App';  // this is a path that needs to reference _src/_
import { renderToString } from 'react-dom/server';
import qs from 'qs';
