Overview

Each OpenStack project provides a command-line client, which enables you to access the project API through easy-to-use commands. For example, the Compute service provides a nova command-line client.

You can run the commands from the command line, or include the commands within scripts to automate tasks. If you provide OpenStack credentials, such as your user name and password, you can run these commands on any computer.

Internally, each command uses cURL command-line tools, which embed API requests. OpenStack APIs are RESTful APIs, and use the HTTP protocol. They include methods, URIs, media types, and response codes.

OpenStack APIs are open-source Python clients, and can run on Linux or Mac OS X systems. On some client commands, you can specify a debug parameter to show the underlying API request for the command. This is a good way to become familiar with the OpenStack API calls.

As a cloud end user, you can use the OpenStack dashboard to provision your own resources within the limits set by administrators. You can modify the examples provided in this section to create other types and sizes of server instances.

The following table lists the command-line client for each OpenStack service with its package name and description.
