Can't disable Webmock / VCR when running rake task

[bgentry]

I'm trying to run the rake knapsack_pro:rspec task on my dockerized Buildkite fleet. However, Webmock is getting in the way:

** Invoke knapsack_pro:rspec (first_time)
** Execute knapsack_pro:rspec
D, [2016-05-06T05:57:53.344852 #55] DEBUG -- : ** [Raven] Event not sent due to excluded environment: test

WebMock::NetConnectNotAllowedError: Real HTTP connections are disabled. Unregistered request: POST http://api.knapsackpro.com/v1/build_distributions/subset with body

Tasks: TOP => knapsack_pro:rspec

I believe I'm ignoring requests to this hostname correctly in my spec_helper.rb:

# Setup VCR
VCR.configure do |config|
  config.cassette_library_dir = 'spec/fixtures/vcr'
  config.hook_into :webmock
  # allow requests to localhost and knapsack pro:
  config.ignore_hosts 'localhost', '127.0.0.1', '0.0.0.0', 'api.knapsackpro.com'
end

Do I need to do something else to get VCR & webmock out of the way for the knapsack_pro rake task?

I did find a workaround. I put this in my Rakefile immediately after the call to load KnapsackPro tasks:

WebMock.disable_net_connect!(:allow => 'api.knapsackpro.com') if defined?(WebMock)

Great. I've updated example of Rakefile in readme.
