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;
