Setup docker to run React app

After setting up docker to generate React app without installing node js in https://gist.github.com/przbadu/4a62a5fc5f117cda1ed5dc5409bd4ac1 It was confusing to some of the devs, how to run react app, so I am creating this as second step to the configuration.

Generate required files in your react project

cd my-react-app
touch Dockerfile Dockerfile.dev docker-compose.yml .dockerignore
