npm bs: webpack loop when executed in docker (Out of the box)

Hi guys,

System: OSx 10.11.6 El Capitan using docker for mac

If you `mern init` a new project; `npm i`; `docker-compose build`; then `docker-compose up` the script gets as far as running `npm run build:server` then it starts to write both the cache-busted header bg image and a `.webpack.res..js` file straight into the root of the project. The webpack task never completes and you have to kill it.

Love the project, btw! Any help would be greatly appreciated

Thanks
