Rails database.yml tasks for Deployment with Capistrano
This gem provide some Capistrano tasks to handle a database.yml file dynamically on the deployment server.
As you now, it is a bad idea to check the database credentials into the source control for security reasons.
So this gem provides a way to create and handle a shared database.yml file for you on your deployment servers.
With this gem you don't need anymore to checkin a database.yml file with all the secrets of your database servers.
Usage
Add the gem to your Rails 3 Project that uses Bundler
gem "rails_database_yml"
Use Bundler to install the gem
bundle install
Require the capistrano tasks in your config/deployment.rb
require "rails_database_yml/capistrano"
That's all.
How it works
This gem asks you in cap deploy:setup for all necessery parameters for your database connection.
Afters this it creates a database.yml file in the folder shared/config.
On every cap deploy the gem creates a symlink to the shared database.yml under current/config.
So your rails application has always a database.yml file that is always the same between all deployments.
