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.

# Getting Started

0. 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
