Ruby Scaffoldings

Ruby Scaffolding is a Habitat package which helps you build your Ruby-based web applications, services, and processes (hereafter referred to as “apps”) into a package which runs consistently
on a wide range of containers, virtual machines, or servers via the Habitat Supervisor. The Supervisor will facilitate clustering, discovery of database services, dynamically update configuration and credentials, coordinate reliable rolling updates, and a lot more.

You can also watch Fletcher demo how to use scaffolding on the Habitat team’s youtube channel!
