heroku-resque-auto-scale¶ ↑

Auto scale your resque workers on Heroku. Original code by darkhelmet:

Modify by joel => github.com/joel

On fork => github.com/joel/heroku-resque-auto-scale

Principals changes :

I’ve switched Jeweler Gem generator to simpel Bundler gem generator
I’ve switched to Rspec from TestUnit
I’ve switched to HerokuAPI Gem instead of Heroku Client Gem

Configuration :

You need to defined two vars for your heroku :

Go to your api.heroku.com/account heroku config:add HEROKU_API_KEY=your_api_key -a your_app_name heroku config:add HEROKU_APP_NAME=your_app_name -a your_app_name

You can test when executed this :

HEROKU_API_KEY=your_api_key HEROKU_APP_NAME=your_app_name *** bundle exec *** rake spec

You can changes thresholds into scaler_config.yml

I just bundled it into a gem for easy inclusion into other projects.

Usage¶ ↑

Once the gem is installed, simply extend your job class as follows:

class ScalingJob
  extend HerokuResqueAutoScale if Rails.env.production? # only extend in production

  def self.perform
    # Do something long running
  end
end

Contributing to heroku-resque-auto-scale¶ ↑

Check out the latest master to make sure the feature hasn’t been implemented or the bug hasn’t been fixed yet
Check out the issue tracker to make sure someone already hasn’t requested it and/or contributed it
Fork the project
Start a feature/bugfix branch
Commit and push until you are happy with your contribution
Make sure to add tests for it. This is important so I don’t break it in a future version unintentionally.
Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
