This project is a skeleton for a rails app following "Quickstart: Compose and Rails"
From this sketch you can run the following commands to jump-start your app:
docker-compose run web rails new . --force --no-deps --database=postgresql
docker-compose run web rails webpacker:install
sudo chown -R $USER:$USER . # Linux only
docker-compose build
Now you should continue from "Connect the database" section of the tutorial
