Monkey-patch for Bundler's release Rake task to push to Gemfury instead of RubyGems.org.

Gemfile

source 'https://rubygems.org/'

gem 'gemfury', '~> 0.4.20'

Rakefile

require 'bundler/gem_tasks'
require 'gemfury'
require 'gemfury/command'

GEMFURY_ACCOUNT = '<Gemfury account>'

# Monkey patch the Bundler Rake task helpers to push the released gem to
# Gemfury instead of RubyGems.org.
module Bundler
  class GemHelper
    unless instance_methods.include?(:rubygem_push)
      fail 'Rake task monkey patch misapplied'
    end

    def rubygem_push(path, account=GEMFURY_ACCOUNT)
      ::Gemfury::Command::App.start(['push', path, "--as=#{GEMFURY_ACCOUNT}"])
      Bundler.ui.confirm "Pushed #{name} #{version} to Gemfury as #{account}"
    end
  end
end

What format does the < Gemfury account > value take?
