This document gives a quick introduction to using the Openstack Python client to discover and consume compute resources.

Before beginning, get an account as described in the Introduction

From a suitable host (this was done on linux.cs.uchicago.edu), create your environment.

$ python3 -m venv cloudsdk
$ source cloudsdk/bin/activate
$ pip3 install openstacksdk
$ python -m openstack version

Obtain your configuration from the Web Interface . The preceding link is for authenticated and authorized users only. Please read Intro for access. After logging in to the web interface at https://overcloud.cs.uchicago.edu, click the menu on the left side, Project→API Access. On the right side of the top of the page, click "Download Openstack RC File"→"Openstack clouds.yaml file".

Save the clouds.yaml file to the current working directory, or see the Upstream Docs about config file search order:
