Network management in OpenStack

OpenStack can be managed in a variety of ways, including through the Horizon dashboard, the Neutron API, and the OpenStack CLI. A command-line client, provided by the python-openstackclient package, gives users the ability to execute commands from a shell that interfaces with the Neutron API. To enter the shell, type openstack in a terminal connected to the controller node, like so:

root@controller01:~# openstack 
(openstack)

 

 

The openstack shell features tab completion and a help command that lists all of the available commands within the shell. Openstack-related commands can also be executed straight from the Linux command line by using the openstack client like so:

# openstack network list
# openstack server create 

The client provides a number of commands that assist with the creation, modification, and deletion of networks, subnets, and ports.

Note

The openstack client is preferred over the neutron client moving forward, but may not have complete command parity...
