Cisco Catalyst Heart Template Labs – Relaxation-APIs – Half 9

Overview

On this episode of our ongoing Catalyst Heart Automation Sequence, our focus strikes to Relaxation-APIs and utilizing postman to automate the community. We are going to change our focus from templating to automation by Postman, an excellent instrument to look at RESTful APIs in a single person interface. This can be a Self-Paced Standalone Lab, the place we are going to construct upon the foundational data acquired within the earlier labs. For this lab, we are going to focus on Catalyst Heart configuration and the way Catalyst Heart might be automated to carry out numerous capabilities we have now already coated. The lab is meant to assist drive the adoption of Relaxation-API and contains a number of use circumstances to unravel frequent orchestration wants when utilizing Catalyst Heart.

Inside this sequence, we cowl the next;

1. PnP Preparation – explains the general Plug and Play arrange steps
2. Onboarding Templates – explains in-depth learn how to deploy Day 0 templates
3. Day N Templates – dives into Day N template constructs with each common and composite templates and use circumstances
4. Utility Policys – explores Utility Policys and SD-AVC in Catalyst Heart and their use
5. Telemetry – explains learn how to deploy Telemetry for assurance
6. Superior Automation – explores Superior Automation strategies
7. Dynamic Automation – a deployment lab for dynamic automation

Catalyst Heart Relaxation-API Collections

Moreover, we have now 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. “Typically seeing is believing.” We hope these new instruments assist clarify learn how to finest use the Relaxation-APIs and increase the knowledge from developer.cisco.com.

On this lab, we are going to regularly add extra use circumstances to reply particular orchestration wants, however all the time in Postman, the place they could be analyzed and seen in operation for inclusion in no matter automation or orchestration system requires them. In upcoming modules, we may even delve into printed and unpublished Relaxation-API and learn how to uncover and work with these to perform your orchestration wants.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 – accumulating a community stock
8. Operating Present Instructions – accumulating present command outcomes

Not like most earlier Labs within the sequence, 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 numerous automation strategies to indicate the whole artwork of the doable from Software program-Outlined Networking.

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

That is an enablement-type lab, permitting engineers and designers to achieve past what they at present perceive by making an attempt new ideas and pushing the boundaries of automation and orchestration. We are going to cowl numerous subjects about Relaxation-API logic to unravel a number of use circumstances throughout this lab. We cowl some earlier ideas with an in-depth deal with broadening their capabilities by the artwork of doing and analyzing.

The idea of this lab is so that you can construct the surroundings 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 through Postman inside a set runner to shortly configure Catalyst Heart. This permits us to deploy Settings, Credentials, Uncover Gadgets, Construct Websites, Buildings, Flooring, and assign the units 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 Catalyst Heart 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 simple to construct the design and deploy templates the place obligatory.

You’ll be able to simply add the Public Workspace to Postman through the next hyperlink. This may 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 surroundings, might be mechanically added. (see picture beneath)

Public Catalyst Heart Use-Case API Assortment

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.  Inside the Workspace are at present a number of collections and an surroundings.

Use Instances

We are going to cowl numerous subjects in a number of use circumstances primarily based on lab modules to indicate the aptitude and suppleness of the Relaxation-APIs with Catalyst Heart.

The assorted subjects/use-cases we are going to contact on and deploy inside the lab include the next:

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

With that, the lab makes use of these subjects…

We are going to acquire a sensible understanding of the steps related to using Relaxation-API whereas establishing a Catalyst Heart and an surroundings to help advanced, superior, common templates to ship system configuration throughout these labs. The labs goal to help engineers in quickly starting to make use of Catalyst Heart automation and assist them work in the direction of a world template technique. Moreover, these labs will give clients a everlasting place to check out the common and composite templates and embrace configurations for numerous use circumstances. Lastly, this surroundings 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 will let you use them as you please inside the time scheduled. As well as, this permits us a spot to start out practising numerous ideas with out worry of impacting manufacturing environments.

Consequently, we hope to demystify a few of the complexities of establishing automation and assist information clients by the caveats. Subsequently, to help clients within the transition towards automation, we have now 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 provide examples you possibly can obtain and broaden from. As well as, the pattern templates and JSON information equipped are for simple import into Catalyst Facilities’ template editor for faster adoption. Lastly, some scripts are ready-made excerpts of code that will let you construct the surroundings to check.

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

The place can I check and check out these labs?
