yarn add dotenv-up
Reference
require('dotenv-up')(3, true, 'sandbox/server.js');
/**
* Use like
* require('dotenv-up')(2); // 2 - default assigned to 'deep' parameter
* require('dotenv-up')(2, false); // second param is "debug" flag - to show on not show each step on the screen
* require('dotenv-up')(2, false, 'name of load'); // plain text to describe individual use of this library
* require('dotenv-up')({
path = process.cwd(),
envfile = '.env',
override = true, // override values in process.env
deep = 1,
startfromlevel = 0,
justreturn = false, // don't add found values to the process.env global object
... other dotenv options https://www.npmjs.com/package/dotenv
* });
*
* @param opt
* @param debug (def: true)
* @param name
* @returns {} - object with all extracted variables

Docker use
require('dotenv-up')({
override : false, // don't override existing parameters in process.env by those from .env file
deep : 3,
}, true, 'sandbox/server.js');
// instead of:
require('dotenv-up')(3, true, 'sandbox/server.js');
// because 'override' flag is by default true

Tip
If you need to include other file that use internally again dotenv-up tool in override mode but you don't want those changes of process.env affect proce.env in you'r scope, do:
const ttt = {...process.env};
require('./lib/lib.js') // with its own require('dotenv-up')(1);
process.env = ttt;
