Building Network Automation Solutions - January 2017 session

1:42:54 Introduction

The introductory section of the January 2017 course covered the logistics, how to get started challenges, and lab questions.

Course Introduction 18:32 2017-01-13

Short course introduction. You might want to skip this if you’re attending a live version of this course - we’ll cover it again in the first live session.

Getting Started 48:21 2017-01-13

In this video you’ll find a few tips that will help you get started with your first network automation project, set the right expectations.

Lab Questions 16:58 2017-01-13

We also covered numerous lab-related questions in the first live session. Most of these discussions have been distilled into lab setup documents, but you might still find them useful.

19:03 How did others get started?

Journey to Open Source World 19:03 2017-01-20

A short interview with Scott Lowe describing his journey into the open-source world.

1:40:50 Network Automation Systems Design

This section focuses on larger systems and components you need to build them. You might think you don’t need it, but you’ll find it very handy when trying to move from small spot fixes that address the most-immediate pains to bigger solutions.

1:05:04 Creating Summary and Compliance Reports

In the second session of the January 2017 course we explored various ways of creating summary- and compliance reports with Ansible. After watching the videos describing the underlying principles and numerous examples you’ll be ready to solve the Easy Wins hands-on exercises.

1:19:59 NETCONF, YANG and OpenConfig

The guest presentation by Marcel Wiget (Juniper) describes YANG data models, briefly introduces NETCONF, and shows how you can use OpenConfig or your custom data model (described in YANG) to configure Junos devices.

1:29:43 Data Models and Data Stores

What is YANG? Why is it useful? Where can I store my data? When should I start using a database instead of text files? What about Excel spreadsheets? What’s the difference between relational and NoSQL databases? You’ll get answers to all these questions in this section.

You’ll also learn how to build a data model describing your network and how you can transform a network- or services-focused data model into a device-focused data model (and when that would be useful).

1:09:28 Case Study: VLAN Service Provisioning

The VLAN Service Provisioning case study starts with simple configuration changes based on service data model, and slowly introduces more complex topics like data model transformation, service decomissioning, and post-deployment validation.

56:15 Continuous Integration in Networking

In his Network Continuous Integration presentation Pete Lumbis explained the basics of Continuous Integration and Continuous Delivery (CI/CD) concepts and demonstrated how you can use GitLab and virtual labs to test network device configurations prior to production deployment.

56:11 Validation, Error Handling and Unit Tests

In this section you’ll learn how to:

  • Write fail-safe playbooks
  • Recover from Ansible module failures and report them
  • Use Ansible logging and debugging tools
  • Debug individual components of your Ansible playbooks (tasks, plays or modules/plugins)
  • Build and automate unit tests
  • Validate input data and device state
