Why am I trying to connect to 127.0.0.1:9092? If I ping kafka I get:

PING kafka (172.18.0.8): 56 data bytes

class MyTopicConsumer < Racecar::Consumer
  subscribes_to "my-topic"

  self.parallel_workers = 5

  def process(message)
    puts "Received message: #{message.value}"
  end
end

bin/racecar -v
#=> Racecar 2.3.0
