Introduction to Kubernetes

Although the DevNet Associate Course in Networking Academy does not require to manage orchestrators like Kubernetes, instructors or students preparing for internships might like to understand the basics of Kubernetes. The information below is based on a CiscoLive online session by Robert Whitaker, Instructional Design & Training Manager, Cisco Systems, Inc. - Distinguished Speaker.

An Introduction to Kubernetes For DevNet Certifications - BRKCRT-2007

Containers are revolutionizing cloud deployments. Kubernetes is a heavily utilized open-source container and service orchestrator. This session is geared towards participants who are interested in taking the DEVCOR and/or DEVOPS certification exam. In this session you will become familiar with Kubernetes and how it is used to deploy applications.

DevNet: Infrastructure as Code

In the DevNet Associate course a lot of attention goes to "Infrastructure as Code", implying that we should stop to change configurations manually. Immutability and Idempotency are key terms. This videos explains the importance of making infrastructure changes indirectly.

Key Takeaways

Make changes indirectly and automatically
Use small composable modules
Validate the infrastructure works as expected
test entire deployments and not only units

DevNet: Terraform Intro & Practice Project

For NetAcad users who are familiar with the DevNet Associate course, here is an additional webinar focusing on Infrastructure as Code with Terraform and cloud provider AWS.

Topics:

• Preparation steps for Amazon Web Services (AWS) and Terraform
• Amazon Machine Images (AMI), AWS Console
• Terraform language, HashiCorp Configuration Language (HCL)
• Terrafom actions: init, plan, apply, destroy
• Declaring resources, ip addressing, subnets, default gateway, security rules
• Installing Apache2

---

Terraform is an open-source infrastructure as code software tool. Learn how it can be utilized to manage and automate your AWS cloud infrastructure. We'll start off by setting up a free AWS account to play around with and move on to setting up and installing Terraform on a Windows/MAC/Linux machine. From there we'll move on to deploying our first resource through terraform and learning other core concepts. You'll even get a chance to setup a simple web server in AWS.

DevNet: Effective Docker Images

In the DevNet Associate course students learn how to create and run Docker images and how to integrate them in to a pipeline. This video teaches the basics of effective Docker images.

Cisco IOS XE Programmability e-book

Cisco IOS XE Programmability e-book
Cisco IOS XE Programmability Automating Device Lifecycle Management

This book provides a summary of the general concepts of programmability supported by Cisco IOS XE. Many books on programmability assume the reader has a background in software development and understands fundamental concepts about how software is built. This book does not make these assumptions. Instead, it is primarily written for network engineers who are new to programmability and wish to understand the basic concepts be fore moving on to advanced topics. For engineers with some programmability experience, this book will summarize the specic capabilities of Cisco IOS XE.

How to Write an Ansible Module - DEVNET-2215 - CiscoLive

Ansible plays an important part in the new DevNet Associate Certification. This presentation from CiscoLive gives you a very practical introduction into  Ansible module. The presenter is John McDonough, Cisco Systems
For viewing the training video registration is required

URL: https://www.ciscolive.com/global/on-demand-library.html?search=DEVNET-2215#/session/1563474075340001OHRH

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

Ansible plays an important part in the new DevNet Associate Certification. This presentation from CiscoLive gives you a very clear and practical introduction. The presenter is Thomas Renzy, Cisco Systems, Inc

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
