OpenStack provides command-line, web-based, and API-based instance management tools. Additionally, a number of third-party management tools are available, using either the native API or the provided EC2-compatible API.
The OpenStack python-novaclient package provides a basic command-line utility, which uses the nova command. This is available as a native package for most Linux distributions, or you can install the latest version using the pip python package installer:
# pip install python-novaclient
For more information about python-novaclient and other available command-line tools, see the OpenStack End User Guide.
