Hands-On Enterprise Automation with Python

By: Bassem Aly

Overview of this book

Hands-On Enterprise Automation with Python starts by covering the set up of a Python environment to perform automation tasks, as well as the modules, libraries, and tools you will be using. We’ll explore examples of network automation tasks using simple Python programs and Ansible. Next, we will walk you through automating administration tasks with Python Fabric, where you will learn to perform server configuration and administration, along with system administration tasks such as user management, database management, and process management. As you progress through this book, you’ll automate several testing services with Python scripts and perform automation tasks on virtual machines and cloud infrastructure with Python. In the concluding chapters, you will cover Python-based offensive security tools and learn how to automate your security tasks. By the end of this book, you will have mastered the skills of automating several system administration tasks with Python.

Managing OpenStack instances from Ansible

Ansible provides modules that can manage the OpenStack instance life cycle, just like we did using APIs. You can find the full list of supported modules at

All OpenStack modules rely on the Python library called shade (, which provides a wrapper around OpenStack clients.

Once you have installed shade on the automation server, you will have access to the os-* modules that can manipulate the OpenStack configuration, such as os_image (to handle OpenStack images), os_network (to create the network), os_subnet (to create and associate the subnet with the created network), os_nova_flavor (to create flavors, given the RAM, CPU, and disk), and finally, the os_server module (to bring up the OpenStack instance).
