Rake task for restarting Heroku workers

heroku.rake

# Add `gem 'heroku-api', :git => 'https://github.com/heroku/heroku.rb.git'` to your Gemfile
# Set the APP_NAME environment variable to the name of the Heroku app you wish to control.
# Set the HEROKU_API_KEY environment variable to the API key found on the Heroku 'My Account' page.

# You can now create a scheduler instance that runs `bundle exec rake heroku:workers:restart` to automate
# restarting workers at a regular interval.

namespace :heroku do
  namespace :workers do
    task :restart do
      heroku = Heroku::API.new
      response = heroku.get_ps(ENV['APP_NAME']) 
      workers = response.body.map {|item| item['process'] }.select { |item| item =~ /worker/ }
      workers.each do |worker|
        puts "Restarting #{worker}"
        heroku.post_ps_restart(ENV['APP_NAME'], 'ps' => worker) rescue nil
      end
    end    
  end
end

Hi - this script uses the Sunset version of the Heroku API and will no longer work.
