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.

Executing your first Fabric file

We now know how the operation works, so we will put it inside fabfile and create a full automation script that can work with remote machines. The first step for fabfile is to import the required classes. Most of them are located in fabric.api, so we will globally import all of them to our Python script:

from fabric.api import *

The next part is to define the remote machine IP addresses, usernames, and passwords. In the case of our environment, we have two machines (besides the automation server) that run Ubuntu 16.04 and CentOS 7.4, respectively, with the following details:

Machine Type IP Address Username Password
Ubuntu 16.04 root access123
CentOS 7.4 root access123

We will include them inside the Python script, as shown in the following snippet:

env.hosts = [
'', # ubuntu machine...
