As mentioned, defining and managing networks can now be done directly through Docker with the addition of the network subcommand. The network command provides you with all the options you need to build networks and connect containers to them:
user@docker1:~$ docker network --help
docker network --help
Usage: docker network COMMAND
Manage Docker networks
Options:
--help Print usage
Commands:
connect Connect a container to a network
create Create a network
disconnect Disconnect a container from a network
inspect Display detailed information on one or more networks
ls List networks
rm Remove one or more networks
Run 'docker network COMMAND --help' for more information on a command.
user@docker1:~$In this recipe, we'll learn how to view defined Docker networks as well as inspect them for specific details.
