title: Docker Bridge Conflicts with Host Network
body: <p>Docker seems to be creating a bridge after a container starts running that then conflicts with my host network.  This is not the default bridge docker0, but rather another bridge that is created after a container has started. I am able to configure the default bridge according to the older user guide link <a href="https://docs.docker.com/v17.09/engine/userguide/networking/default_network/custom-docker0/" rel="noreferrer">https://docs.docker.com/v17.09/engine/userguide/networking/default_network/custom-docker0/</a>, however, I do not know how to configure this other bridge so it does not conflict with 172.17. </p>
  
  <p>This current issue is then that my container cannot access other systems on the host network when this bridge becomes active.</p>
  
  <p>Any ideas?</p>
  
  <p>Version of docker:</p>
  
  <pre><code>Version 18.03.1-ce-mac65 (24312)
  </code></pre>
  
  <p>This is the bridge that gets created. Sometimes it is not 172.17, but sometimes it is.</p>
