Overview of this book

Networks in your infrastructure set the foundation for how your application can be deployed, maintained, and serviced. Python is the ideal language for network engineers to explore tools that were previously available to systems engineers and application developers. In this second edition of Mastering Python Networking, you’ll embark on a Python-based journey to transition from traditional network engineers to network developers ready for the next-generation of networks. This book begins by reviewing the basics of Python and teaches you how Python can interact with both legacy and API-enabled network devices. As you make your way through the chapters, you will then learn to leverage high-level Python packages and frameworks to perform network engineering tasks for automation, monitoring, management, and enhanced security. In the concluding chapters, you will use Jenkins for continuous network integration as well as testing tools to verify your network. By the end of this book, you will be able to perform all networking tasks with ease using Python.

The Ansible Arista example

The final playbook example we will look at will be the Arista command module. At this point, we are quite familiar with our playbook syntax and structure. The Arista device can be configured to use transport using cli or eapi, so, in this example, we will use cli.

This is the host file:

[eos_devices]
A1 ansible_host=192.168.199.158

The playbook is also similar to what we have seen previously:

    ---
- name: EOS Show Commands
hosts: "eos_devices"
gather_facts: false
connection: local

vars:
cli:
host: "{{ ansible_host }}"
username: "arista"
password: "arista"
authorize: true
transport: cli

tasks:
- name: eos show commands
eos_command:
commands:
- show version | i Arista
provider: "{{ cli }}"
register: output

- name: show output
debug:
var: output

The output will show the standard output as we would expect...
