This is a dockerized Ruby on Rails 5.1 app with React enabled.

git clone https://github.com/ilyasotkov/rails-react-boilerplate
cd rails-react-boilerplate
docker-compose build
docker-compose run app npm install
docker-compose up

If you make any changes to the Gemfile, then run docker-compose build after to install the gems.

React components will hot-reload as expected, and normal .erb Rails views will auto-reload using guard-livereload gem. For some reason initial setup is painfully slow (40 seconds before initial load), but fortunately after that hot-reloading is very fast.

The Dockerfile can be both used in production and in development.

The image is 214 MB compressed. The Dockerfile can be optimized for smaller size in production, but I chose to use 1 Dockerfile for simplicity here.

I'm actively developing solutions for automated deployment using Docker Swarm and Kubernetes.
