CLI help

If you forget how a specific CLI command works, you can always rely on the help! Here are some examples of using python-openstackclient help.

Using the help is a two-step process.

Step 1: Determine how to perform a particular action using openstack help.

You can filter specific actions using grep. Here are some examples:

$ openstack help | grep domain
$ openstack help | grep project
$ openstack help | grep image
$ openstack help | grep server
$ openstack help | grep network
$ openstack help | grep volume  

Step 2: After you find out the action you want to perform, you can provide --help to explore all available positional arguments and flags. Here are some examples:

$ openstack domain create --help
$ openstack project create --help
$ openstack image add project --help
$ openstack server create --help
$ openstack network list --help
$ openstack router create --help
