Tired of setting hardcoded ips or dns names in your capistrano deploy script? You just found the solution!

cap-aws-ec2 will fetch instances from you EC2 region and define them by project, environment and roles.

This gem should be used in conjunction with capistrano multistage

Note: This gem is only compatibale with Capistrano 2.x

Add this line to your application's Gemfile:

gem 'cap-aws-ec2', require: false

And then execute:

$ bundle

Or install it yourself as:

$ gem install cap-aws-ec2

1. Define tags for your servers on EC2:

2. In your deploy.rb script:

require 'cap-aws-ec2'
set :aws_key_id, 'XXXXXXXXXXXXXX'
set :secret_access_key, 'XXXXXXXXXXXXXXXXXXXX'
set :aws_region, 'us-west-2' 
set :ec2_project, 'my-project-tag-value'
set(:ec2_env) { stage }

3. In your corresponding stage file (config/deploy/production.rb):

define_servers

This will result in the following statements:

server 1.1.1.1, :app, :web
server 2.2.2.2, :app, :web
server 3.3.3.3, :app, :resque

1. Fork it ( http://github.com//cap-aws-ec2/fork )

3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
