Creating instances from Python

To get instance up and running, OpenStack instances require three components. The boot image, which is provided by glance, the network ports, which provided by neutron, and finally, the compute flavor that defines the number of CPUs, amount of RAM that will be allocated to the instance and disk size. The flavor is provided by nova project.

Creating the image

We will start by downloading a cirros image to the automation server. cirros is a lightweight, Linux-based image, used by many OpenStack developers and testers around the world to validate the functionality of OpenStack services:

#cd /root/ ; wget

Then, we will upload the...
