Allow to specify the host for a mock service

[ThomasKoppensteiner]

Currently only the port can be specified for a MockService. The host is hard coded to localhost.

pact-ruby/lib/pact/consumer/configuration/mock_service.rb

Lines 54 to 61 in 866d89d

	def register_mock_service
	unless standalone
	url = "http://localhost#{port.nil? ? '' : ":#{port}"}"
	ret = Pact::MockService::AppManager.instance.register_mock_service_for(provider_name, url, mock_service_options)
	raise "pact-mock_service(v#{Pact::MockService::VERSION}) does not support 'find available port' feature" unless ret
	@port = ret
	end
	end

The AppManager itself also doesn't allow to specify URIs other than http://localhost.

def register_mock_service_for(name, url, options = {})
   uri = URI(url)
   raise "Currently only http is supported" unless uri.scheme == 'http'
   raise "Currently only services on localhost are supported" unless uri.host == 'localhost'
   uri.port = nil if options[:find_available_port]

   app = Pact::MockService.new(
     name: name,
     log_file: create_log_file(name),
     pact_dir: pact_dir,
     pact_specification_version: options.fetch(:pact_specification_version)
   )
   register(app, uri.port)
end

Is there a good reason for that restriction? Our CI environment provides dependencies (other services) on other hosts than localhost.
Are there any plans to changes this?

Time.

I've done it now, but I have to be honest, I haven't tested it on anything other than 127.0.0.1 and 0.0.0.0 (time again). Please try it and let me know how you go.

Can some one help me understand how to provide the host name here ? In the pact_helper.rb ?

[bethesque]

Yes, in the pact_helper.rb
