Capistrano plugin that enable discovery of instances in ec2 AutoScale groups into capistrano deployment script.

• aws-sdk
• capistrano ~> 2.15.5

Add this line to your application's Gemfile:

gem 'capistrano-autoscale-deploy'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install capistrano-autoscale-deploy

Add this line to your application's Capfile:

require 'capistrano/autoscale_deploy'

And set credentials with AmazonEC2ReadOnlyAccess permission in config/deploy.rb as:

set :aws_default_region, 'eu-west-1'
set :aws_access_key_id, "YOUR AWS KEY ID"
set :aws_secret_access_key, "YOUR AWS SECRET KEY"

In the capistrano deploy script / stage files add the following line

autoscale :AutoScaleGroup => 'name of AutoScale group (by Name tag)', :deploy_roles => [:app, :web, :db, :primary => true]

you can add more autoscale configs to deploy to multiple autoscale groups like a cluster

This gem will fetch only running instances that have an autoscale tag name you specified

It will then reject the roles of :db and the :primary => true for all servers found but the first one

(from all autoscale groups you have specified such as using more then once the autoscale directive in your config - i.e cluster deploy)

this is to make sure a single working task does not run in parallel

you end up as if you defined the servers yourself like so:

server ip_address1, :app :db, :web, :primary => true
server ip_address2, :app, :web
server ip_address3, :app, :web
