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

No more excuses! You need to take ownership your career and your life. No one else is going to do that for you. It is up to you. Are you going to complain? Or are you going to do something about it?

Two books:

Extreme Ownership: How U.S. Navy SEALs Lead and Win: https://amzn.to/2v1M8eC

Discipline Equals Freedom: Field Manual: https://amzn.to/2UQPq2T

I recommend these books if you need some motivation!

FIND YOUR WILL, FIND YOUR DISCIPLINE--AND YOU WILL FIND YOUR FREEDOM

Jocko Willink's methods for success were born in the SEAL Teams, where he spent most of his adult life, enlisting after high school and rising through the ranks to become the commander of the most highly decorated special operations unit of the war in Iraq. In Discipline Equals Freedom, the #1 New York Times bestselling coauthor of Extreme Ownership describes how he lives that mantra: the mental and physical disciplines he imposes on himself in order to achieve freedom in all aspects of life. Many books offer advice on how to overcome obstacles and reach your goals―but that advice often misses the most critical ingredient: discipline. Without discipline, there will be no real progress. Discipline Equals Freedom covers it all, including strategies and tactics for conquering weakness, procrastination, and fear, and specific physical training presented in workouts for beginner, intermediate, and advanced athletes, and even the best sleep habits and food intake recommended to optimize performance.

Within these pages discover the keys to becoming stronger, smarter, faster, and healthier. There is only one way to achieve true freedom: The Way of Discipline. Read this book and find The Way.

Christmas Giveaway! And I disagree with Network Chuck! There is ONE SKILL that will set you apart from the rest is: THE ABILITY TO LEARN! You have to learn how to learn. This is the most important skill you need to gain. Then learn how to communicate. You need to be able to learn both technical and soft skills. With the ability to learn and change yourself, you can learn anything.
