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?

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! David Bombal bookclub: http://davidbombal.club #jockowillink #career #movtivation 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.
