OpenStack API Guide

OpenStack API Guide

Although you install each OpenStack service separately, the OpenStack services work together to meet your cloud needs: Identity, Compute, Images, Block Storage, Networking (neutron), Object Storage, Databases, and Metering. With the TryStack OpenStack installation, these services work together in the background of the installation.

After you authenticate through Identity, you can use the other OpenStack APIs to create and manage resources in your OpenStack cloud. You can launch instances from images and assign metadata to instances through the Compute API or the openstack command-line client.

To begin sending API requests, use one of the following methods:

  • cURL

    A command-line tool that lets you send HTTP requests and receive responses. See the section called OpenStack APIs.

  • OpenStack command-line client

    The OpenStack project provides a command-line client that enables you to access APIs through easy-to-use commands. See the section called OpenStack command-line clients.

  • REST clients

    Both Mozilla and Google provide browser-based graphical interfaces for REST. For Firefox, see RESTClient. For Chrome, see rest-client.

  • OpenStack Python Software Development Kit (SDK)

    Use this SDK to write Python automation scripts that create and manage resources in your OpenStack cloud. The SDK implements Python bindings to the OpenStack API, which enables you to perform automation tasks in Python by making calls on Python objects rather than making REST calls directly. All OpenStack command-line tools are implemented by using the Python SDK. See OpenStack Python SDK in the OpenStack End User Guide.
