Ansible is a configuration management system that can be used to manage data center devices and controllers, from servers and switches to Cisco Intersight and Cisco Application Centric Infrastructure. There are thousands of Ansible modules that may provide all the functionality you need. However, in the event that the module with the functionality you need is not available you can create your own. In this session, you will learn how to create an Ansible module that follows the guidelines set by the Ansible community. This session includes the building of a module from the ground up. You will learn how to set up your Ansible development environment, gain an understanding of module idempotence and how to appropriately employ the basic constructs of an Ansible module. Using the concepts learned in this session you may even want to contribute your module to Ansible for inclusion in a future release.

 

Introduction to Automating ACI with Ansible - DEVNET-1797 - CiscoLive

Application Centric Infrastructure (ACI) is a Data Center Architecture with centralized programmability and policy driven capabilities. Ansible is a simple automation language that uses the concept of playbooks to automate configurations of ACI using modules designed for Ansible for configuration provisioning. In this session, we will introduce Ansible and concepts such as playbooks and modules. We will then look at demo of how Ansible can be used to automate ACI provisioning of Tenants as well as looking at deploying a three tier application. We finally will look at scaling ACI playbooks.

DevNet Associate NetAcad Course - Summer 2020

The new DevNet Associate NetAcad Course (DevASC) is to be expected in the Summer of 2020.

Play with Linux and Python on the Networking Devices -- Online Webinar

Play with Linux and Python on the Networking Devices, 8 May, 9:00 a.m. Pacific Daylight Time: Register Here

What app would you develop if you could run it directly on a router or a switch? What full-stack system would you want to deploy and run directly on a router or a switch if they could run a full Linux operating system? Now that your imagination is running wild, join this session to learn how on a network infrastructure you can now run your Python code directly from the IOS CLI. You will also learn how to spin up a full Linux container on a router with either your favorite network performance-monitoring tool or with a chat-bot app that lets you manage the network from a messenger app on your phone.

If you register, you will get access to the recording.

Practical Introduction to Emerging Technologies/ Network Programmability/ 30 NOV 2018

On 30 November there is a practical introduction to Network Programmability during the Global Online IPD Week, in Dutch language.

Presentations - used during the session

• Download En_ETW_Overview-PPT_v1.0 (5)
• Download ETW APIC-EM (1)

PATH TRACE - Sample Python Code 

• Download DevNet Ticket Hosts Network Devices Path Trace

CODING PRACTICE

• Coding is not new to Cisco. There have always been talented programmers for the IOS and for network applications.
• Writing simple code based on examples is easy.
• Writing complex code is difficult.
• Writing complex declarative CLI scripts is no easy task either.
• In the future a number of networkers will be writing code, if they like it.
• But even more networkers will run the code, and maybe adapt it.

MapQuest Directions API Application

In the Emerging Technologies Workshops about SDN and APIC-EM students will use Python to get hands-on practice with libraries and APIs for remote network management. There is an initial lab in the student course in which you learn to get information about real world route directions using the MapQuest Directions API.

=>   If you are a Cisco NetAcad Instructor and wish to access this course, send an email to <yvan@biasc.be> with the subject line "Access to Emerging Technology Workshop SDN & APIC-EM"

 

Sample Lab - Parsing JSON with a Python Application

In this lab, students will create an application that retrieves JSON data from the MapQuest Directions API, parses the data, and formats it for output to the user. You will use the GET Route request from the MapQuest Directions API. Review the GET Route Directions API documentation here:

URL: https://developer.mapquest.com/documentation/directions-api/route/get/
Note: If the above link no longer works, search for “MapQuest API Documentation”

For accessing the lab you will have to be enrolled in the Emerging Technologies Course. This is free for NetAcad Instructors

DevNetAcad Reloaded

From now until June 2019 Cisco’s DevNet and Networking Academy have teamed up again for another webinar series because of the high interest from last year's series. In our ever changing technology landscape, it only makes sense to revisit a few sessions from last year and share the latest details as well as feature a whole new set of topics. Join the webinars for conversations about network programmability, security, SDN and network controllers, Python, and many other related topics.

 

• Session 1: Networking with Programmability is Easy
• Session 2: Role of a Network Engineer in the Programmable Age
• Session 3: Software Defined Networking and Controllers
• Session 4: Adding API Skills to Your Networking Toolbox to be held in January 2019
• Session 5: The New Programmable Toolbox of a Networking Engineer to be held in February 2019
• Session 6: Program Networking Devices using their APIs to be held in March 2019
• Session 7: Before, During, and After a Security Attack to be held in April 2019
• Session 8: Play with Linux and Python on the Networking Devices to be held in May 2019
