Cisco DNA Middle Template Labs – Relaxation-APIs – Half 9


Overview

On this episode of our ongoing DNA Middle Automation Collection, our focus strikes to Relaxation-APIs and utilizing postman to automate the community. We’ll change our focus from templating to automation by Postman, an excellent instrument to look at RESTful APIs in a single consumer interface. It is a Self-Paced Standalone Lab, the place we’ll construct upon the foundational information acquired within the earlier labs. For this lab, we’ll consider DNA Middle configuration and the way DNA Middle might be automated to carry out varied features now we have already lined. The lab is meant to assist drive the adoption of Relaxation-API and contains a number of use circumstances to unravel widespread orchestration wants when utilizing DNA Middle.

DNA Middle Relaxation-API Collections

Moreover, now we have supplied a Postman Public Workspace the place all of the Relaxation-API Collections are included in order that engineers can quickly entry and arrange their environments. “Generally seeing is believing.” We hope these new instruments assist clarify tips on how to finest use the Relaxation-APIs and increase the knowledge from developer.cisco.com.

On this lab, we’ll frequently add extra use circumstances to reply particular orchestration wants, however all the time in Postman, the place they could be analyzed and considered in operation for inclusion in no matter automation or orchestration system requires them. In upcoming modules, we will even delve into revealed and unpublished Relaxation-API and tips on how to uncover and work with these to perform your orchestration wants.

Inside this lab modules, we cowl the next using collections for orchestration with the help of a comma-separated values (CSV) file;

  1. Postman Orientation – orientates you to Postman and helps put together the instruments
  2. Constructing Hierarchy – the orchestration of constructing hierarchy
  3. Assign Settings and Credentials – assigning settings and credentials
  4. Gadget Discovery – orchestrating system discovery
  5. Template Deployment – automating template deployment
  6. Configuration Archive – automating configuration archiving
  7. Retrieving Community Stock – amassing a community stock
  8. Working Present Instructions – amassing present command outcomes

Not like most earlier Labs within the collection, this lab is self-contained and has no dependencies on any earlier labs. When you can add ideas from Labs 5 and 6 to this lab, it’s designed to haven’t any pre-configuration. It makes use of varied automation methods to indicate the whole artwork of the attainable from Software program-Outlined Networking.

What’s going to I study within the Relaxation-API Orchestration Lab?

That is an enablement-type lab, permitting engineers and designers to succeed in past what they at the moment perceive by attempting new ideas and pushing the boundaries of automation and orchestration. We’ll cowl varied matters about Relaxation-API logic to unravel a number of use circumstances throughout this lab. We cowl some earlier ideas with an in-depth concentrate on broadening their capabilities by the artwork of doing and inspecting.

The idea of this lab is so that you can construct the setting from the bottom up, from Design to Discovery to Template Deployment. The usage of dCloud or the DevNet Sandbox permits a secure place so that you can attempt, modify, and get used to the varied ideas and approaches.

Method

The Lab is constructed for minimal intervention utilizing issues like Relaxation-API run by way of Postman inside a set runner to shortly configure DNA Middle. This enables us to deploy Settings, Credentials, Uncover Gadgets, Construct Websites, Buildings, Flooring, and assign the gadgets to these websites. These are highly effective examples of what we are able to do, they usually display how shortly we are able to get DNA Middle up and operating using Relaxation-API utilizing only one instrument.

However wait, there may be extra…

We provisioned a comma-separated worth (CSV) file to be used with the Postman collections to make it straightforward to construct the design and deploy templates the place crucial.

CSV
Determine 1. CSV File

You’ll be able to simply add the Public Workspace to Postman by way of the next hyperlink. It will let you quickly begin utilizing the Relaxation-API suite created for this lab. Click on the next hyperlink and log into your Postman account, and the workspace, together with the collections and the setting, will probably be routinely added. (see picture under)

Public DNA Middle Use-Case API Assortment

Postman Public Workspace
Determine 2. Postman Public Workspace

We preserve Postman Public Workspace updated with the lab in order that the lab helps doc the gathering, and the collections assist drive the lab.  Throughout the Workspace are at the moment a number of collections and an setting.

Use Circumstances

We’ll cowl varied matters in a number of use circumstances based mostly on lab modules to indicate the potential and suppleness of the Relaxation-APIs with DNA Middle.

The assorted matters/use-cases we’ll contact on and deploy throughout the lab include the next:

  1. Utilizing Relaxation-API to configure DNA Middle Design and Settings utilizing a CSV file
  2. Automation of assigning Credentials throughout the community
  3. Orchestrating Discovery to onboard community gadgets
  4. Automating the Provisioning of Common and Composite Templates to Gadgets
  5. Retrieving Gadget Stock data
  6. Orchestration of Configuration Archives
  7. Retrieving Present Command outcomes from DNA Facilities Command Runner

With that, the lab makes use of these matters…

We’ll achieve a sensible understanding of the steps related to using Relaxation-API whereas establishing a DNA Middle and an setting to help advanced, superior, common templates to ship system configuration throughout these labs. The labs purpose to assist engineers in quickly starting to make use of DNA Middle automation and assist them work in the direction of a worldwide template technique. Moreover, these labs will give clients a everlasting place to check out the common and composite templates and embody configurations for varied use circumstances. Lastly, this setting will allow engineers to scale back the effort and time wanted to instantiate the community.

Beginning…

Inside dCLOUD, a number of sandbox-type labs can be found. These self-contained environments are there to let you use them as you please throughout the time scheduled. As well as, this enables us a spot to begin training varied ideas with out worry of impacting manufacturing environments.

Consequently, we hope to demystify a number of the complexities of establishing automation and assist information clients by the caveats. Subsequently, to assist clients within the transition towards automation, now we have put collectively a set of small useful labs inside a Github repository. This manner, these self-guided labs present a glimpse into the basics of constructing velocity templates and supply examples you’ll be able to obtain and develop from. As well as, the pattern templates and JSON recordsdata provided are for simple import into DNA Facilities’ template editor for faster adoption. Lastly, some scripts are ready-made excerpts of code that let you construct the setting to check.

On this sensible lab, Relaxation-API Orchestration, we step-by-step delve into superior automation strategies and methods to make the most of them to unravel varied use circumstances. Second, we offer solutions and explanations to most of the questions that come up throughout automation workshops. We hope that you just discover the knowledge each useful and informative.

The place can I take a look at and take a look at these labs?
