6. HOW TO: Use OpenStack

7. STEP 1: Get pyrax
STEP 2: Set up authentication
STEP 3: Run a Python script
STEP 4: Verify on Control Panel

8. Step 1: Get pyrax
‣ Demo on Ubuntu 12.04
Rackspace Cloud Server (get
you one!)
‣ pip install pyrax

9. Step 2: Set up authentication
‣ Create ~/.pyrax.cfg with:
[default]
identity_type = rackspace
keyring_username = yourusername
debug=True
‣ Also, in the code itself, username and API Key:
pyrax.set_credentials("annegentle",
"486edc1d76c0981b7a5f998c9f4b8849")

10. Step 3: Run tutorial, spin up servers
‣ Create pyrax_tutorial.py file
https://gist.github.com/EdLeafe/5665994
#!/usr/bin/env python
# -*- coding: utf-8 -*-
import pyrax
# First you need to authenticate.
pyrax.keyring_auth()
# Create a shortcut alias for
cloudservers
cs = pyrax.cloudservers
# Get the image for Ubuntu 12.04
image = [img for img in cs.list_images()
if "Ubuntu 12.04" in img.name][0]
# Flavors are RAM/disk combinations.
flavor = cs.list_flavors()[0]
# Create the first server
server1 =
cs.servers.create(name=“Buntuone",
image=image.id,
flavor=flavor.id)
…

11. Step 4: Verify on Control Panel
‣ Go to http://mycloud.rackspace.com
