Capistrano::Getservers

capistrano-getservers makes it easier for you to deploy to your EC2 instances. By supplying a Hash to the get_servers method, capistrano-getservers connects to EC2 and retrieves all instances with matching tags.

Installation

Add this line to your application's Gemfile:

gem 'capistrano-getservers'

And then execute:

$ bundle

Or install it yourself as:

$ gem install capistrano-getservers

Requirements

Ruby Gems

• gem 'capistrano'
• gem 'fog'

Environment variables

• export AWS_SECRET_ACCESS_KEY=''
• export AWS_ACCESS_KEY_ID=''

Usage

Retrieving instances within Capistrano

In your capistrano script:

get_servers(:db, 'us-east-1', {'app' => 'app_name', 'cluster' => 'cluster', 'environment' => 'environment' ... })

Retrieving instances from your CLI

In your capistrano script:

set :tags, ENV['TAGS'] || {}
cli_tags = parse(tags)
get_servers(:role, region, cli_tags)

Then, via the command line:

$ cap staging deploy TAGS=key1:value1,key2:value2,key3:value3...

Notes

You can pass nil as the second parameter to have capistrano-getservers default to the us-east-1 region.

All servers will receive the role 'web' unless you specify a different role using the get_servers method.

Example: get_servers(:role, 'us-east-1', {'deploy' => 'some value', 'app' => 'some_value'})

Changelog

Version 1.0.2:

• Added region support for Getservers. Had to change the function get_servers for this, so it's now: get_servers(:role,'region',tags)
