This is a demo Ruby on Rails app you can deploy to Skyliner. Here's a guide to getting started:

Differences from a stock Rails application

• Depends on the lograge gem, which converts Rails's weirdly verbose logging into production-ready logging using Logstash JSON formatting.
• Depends on Heroku's rails_12factor gem, which directs the logs to stdout and allows Rails to serve up static assets. (If static asset serving becomes a performance hotspot, we recommend setting up CloudFront.)
• Commits secrets.yaml to source control. It pulls the production secret base from the SECRET_KEY_BASE environment variable, which is securely managed by Skyliner.
• Adds quotes to the use of SECRET_KEY_BASE in secrets.yaml, which prevents a secret with all digits from being interpreted as a number.
• Depends on puma-heroku, which borrows Heroku's recommended Puma configuration.

Setting up a database

• Follow the directions here to create an RDS instance of your preferred database.
• Edit the config/database.yml file in your project and modify the production entry to look like the following:

<dev and test stuff here>

production:
  url: "<%= ENV["DATABASE_URL"] %>"

• In Skyliner, go to the Setting page for your app and select the Configuration section.
• Click the gear to edit the settings and enter DATABASE_URL in the key field and the database url for your database in the value field.
• Select the Skyliner environment you want the setting to apply to (QA or Production).
• Click Update to save your settings.
• Re-deploy to the environment you are interested in.
