3. OpenStack Client (CLI)

The OpenStack Client is a self-contained OpenStack project providing a command line interface to the most important cloud functions. For most of the API calls an equivalent CLI command is available under a shared command invoked as openstack. An example is openstack server list. For reference see the documentation of the OpenStack Client (OSC).

The OTC Extensions don’t re-implement the CLI tool, but augment it automatically. If you have installed OTC Extensions and OpenStack Client, the latter understands many extra commands:

openstack --help | grep -c otcextensions
164

For details of the available commands, check the detailed CLI documentation of these services:
