Overview
Hadoken hosts Rails applications. You point it at a Rails app, and it handles everything else: building a container, running migrations, provisioning TLS, and giving you a live URL. There are no config files to write.
The CLI is a standalone binary (not a Ruby gem). It reads your Gemfile.lock to detect your Ruby version, database adapter, and which parts of the Rails stack you're using. Then it packages your source, builds an image, deploys it, and prints the URL.
After deploy, you get logs, environment variables, a Rails console, and the ability to run one-off commands -- all through the same CLI.
