Your docker closes because the tty is not enabled. In order to work, you have to run the docker with

docker run -t -p 7000:3000 react-app:latest

For more info: https://github.com/facebook/create-react-app/issues/8688

But this should be only for testing/development. In production you should build your react app and then serve it with serve or with nginx
