Перемещение файлов stati c в контейнер docker

Question

Я хотел бы создать Dockerfile, который создает файлы stati c для реагирующего приложения и скопировать его в другое изображение.

Когда я запускаю docker-compose up с файлами ниже, я нахожу, что В контейнере nginx нет файлов, которые я хочу в /config/www. Есть идеи, что мне не хватает?

docker -compose.yml

The project was built assuming it is hosted at the server root.
You can control this with the homepage field in your package.json.
For example, add this to build it for GitHub Pages:
  "homepage" : "http://myname.github.io/myapp",
The build folder is ready to be deployed.
You may serve it with a static server:
  npm install -g serve
  serve -s build
