capistrano3-aws-asg-deploy

Capistrano 3 plugin for AWS Auto Scaling deploys.

This is a fork of Aftab-Akram/capistrano3-asg-deploy, updated with new features and Capistrano 3 conventions.

I'm mainly building this gem to work with private ip address

• aws-sdk-ec2 ~> 1
• aws-sdk-autoscaling ~> 1
• capistrano ~> 3

Add this line to your application's Gemfile:

gem 'capistrano3-aws-asg-deploy'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install capistrano3-aws-asg-deploy

Add this line to your application's Capfile:

require 'capistrano/autoscaling_deploy'

Set credentials with AmazonEC2FullAccess permission in the capistrano deploy script / stage files add the following lines

set :aws_region, 'ap-northeast-1'
set :aws_access_key_id, 'YOUR AWS KEY ID'
set :aws_secret_access_key, 'YOUR AWS SECRET KEY'
set :aws_autoscaling_group_name, 'YOUR NAME OF AUTO SCALING GROUP NAME'
set :aws_deploy_roles, [:app, :web, :db]
set :aws_deploy_user, 'USER FOR SSH CONNECTION'

invoke 'autoscaling_deploy:setup_instances'

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

This gem will fetch only running instances that have an auto scaling group 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 auto scaling groups you have specified such as using more then once the auto scaling 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

1. Fork it ( https://github.com/maximbaibakov/capistrano3-aws-asg-deploy/fork )
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Add some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

To test while developoing just bundle console on the project root directory and execute Capistrano::AutoScalingDeploy::VERSION for a quick test
