#39: Which Network Automation Tools should I learn? Python, Ansible, Genie and more

It's confusing! Where do I start with network automation? Which tools should I learn? Hank Preston opens the Network Automation Tool Chest and tells us which tools we should learn. We have a roadmap of tools to learn, how to start learning and how to deploy in the real world. Which tools are best to start with? python or ansible or netmiko or pyats or paramiko? We discuss lots of options in this video. #Python #Ansible #Genie Links: DevNet home page: http://bit.ly/2MHbgOk Network programmability Basics Video Series: http://bit.ly/2GGzg2T Laptop Setup Labs: http://bit.ly/2GGzh6X Coding Fundamentals Learning Labs: http://bit.ly/2ZK8yiP Ansible Learning Labs: http://bit.ly/2ZEdqFY Menu: 0:38 - What Network Automation Tools 02:56 - The NetDevOps Engineer's Tool Chest 06:42 - Network Service and Configuration Management tools 10:36 - Where to start - Netmiko 12:55 - Genie CLI 15:00 - Ansible 20:20 - Domain Specific Language 22:14 - Python vs Ansible 24:08 - Napalm + Nornir 27:15 - Issues with Napalm and Netmiko 28:19 - Real World Use Cases of network automation tools 30:02 - pyATS & Paramiko 33:49 - pyATS & Genie 41:04 - DIFF 42:54 - How to schedule Network Automation 45:06 - Do Network Engineers need to learn Linux?

Foundation "Stuff" * Python * Linux/bash fundamentals * git * REST APIs 1. CLI Based Interactions * Python + Netmiko - Configuration Based use cases * Genie CLI - Operation based use cases * Parmiko - NOT RECOMMENDED - just use Netmiko 2. Network Automation Frameworks/Abstractions * Ansible "Domain Specific Language (DSL)" - Configuration Use Cases * NAPALM + Python - Configuration Use Cases * Nornir + Python - Configuration Use Cases 3. Network Verification * pyATS/Genie + Python - Operational / Testing Use Cases * For every BGP neighbor, ensure prefixes being learned * For every "up interface", ensure no CRC errors * "Profile" before change, Change, "Profile" after, DIFF Other Skills/Questions 1. How to schedule "stuff" * Run a Python script every hour - cron utility on Linux/Unix/macOS * Orchestration/Integration Tools - (CICD Tools) - Jenkins, Drone, Gitlab * "Event Driven" * Central Management Servers - Ansible Tower # Real World Use Cases * Scale * Performance * Transactions/Error Recovery David's details: YouTube: www.youtube.com/davidbombal Twitter: twitter.com/davidbombal Instagram: www.instagram.com/davidbombal/ LinkedinIn: www.linkedin.com/in/davidbombal/ #python #netdevops #devnet #genie #pyats #python #netmiko
