Capistrano deployment email notifier for Rails 3
Do you need to send email notifications after application deployments?
Christopher Sexton developed a Simple Capistrano email notifier for rails. You can find details at http://www.codeography.com/2010/03/24/simple-capistrano-email-notifier-for-rails.html.
Here is Rails 3 port of the notifier.
The notifier sends an email after application deployment has been completed.

RightScale script to generate rails database.yml file upon server launch
#!/bin/bash -ex
# Create database.yml for a Ruby on Rails application
# Storing database.yml in a source code control system with its production database credentials creates a security risk.
# Using this script, you can take advantage of RightScale's secure credentials store
# and generate the file when an application server is launched.
#
# If this is a reboot skip this script.
