title: how to connect Docker containers without a bridge?
body: <p>I'm having some experiments to do with Docker container technology.</p>
  <p>I need for a specific reason to connect two veth container interfaces together without using a bridge, Docker creates a bridge by default, so I do not want to use it.</p>
  <p>I'm confused and want to know if it is right to do that way. Anyone can give advices and point me out some links or methods ? I will appreciate.</p>
  <p>Thank you so much.</p>
