Is your intention to expose the ports of a docker container? If you want to do this search for &quot;expose&quot; ports. The docker run option is -p and -P for this.<p>Or to create a subnet with custom IP for the docker daemon&#x27;s bridge network? Use -b option to docker daemon.<p><a href="https:&#x2F;&#x2F;docs.docker.com&#x2F;engine&#x2F;userguide&#x2F;networking&#x2F;" rel="nofollow">https:&#x2F;&#x2F;docs.docker.com&#x2F;engine&#x2F;userguide&#x2F;networking&#x2F;</a> is a good place to start. If you have a specific question, feel free to ask and I can try to answer.
