    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 way of Postman, an excellent device to look at RESTful APIs in a single consumer interface. This can be a Self-Paced Standalone Lab, the place we are going to construct upon the foundational information acquired within the earlier labs. For this lab, we are going to think about DNA Middle configuration and the way DNA Middle might be automated to carry out numerous capabilities we’ve got already coated. The lab is meant to assist drive the adoption of Relaxation-API and consists of a number of use circumstances to unravel frequent orchestration wants when utilizing DNA Middle.

    DNA Middle Relaxation-API Collections

    Moreover, we’ve got offered 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 methods to greatest 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 at all times 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 In upcoming modules, we will even delve into printed and unpublished Relaxation-API and methods to uncover and work with these to perform your orchestration wants.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 gadget discovery
    5. Template Deployment – automating template deployment
    6. Configuration Archive – automating configuration archiving
    7. Retrieving Community Stock – gathering a community stock
    8. Operating Present Instructions – gathering present command outcomes

    In contrast to most earlier Labs within the sequence, this lab is self-contained and has no dependencies on any earlier labs. Whilst you can add ideas from Labs 5 and 6 to this lab, it’s designed to don’t have any pre-configuration. It makes use of numerous automation strategies to indicate the entire 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 succeed in past what they at the moment perceive by attempting new ideas and pushing the boundaries of automation and orchestration. We’ll cowl numerous matters about Relaxation-API logic to unravel a number of use circumstances throughout this lab. We cowl some earlier ideas with an in-depth give attention to broadening their capabilities by way of 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. Using dCloud or the DevNet Sandbox permits a protected place so that you can attempt, modify, and get used to the varied ideas and approaches.

    Strategy

    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 units to these websites. These are highly effective examples of what we are able to do, they usually exhibit how shortly we are able to get DNA Middle up and working using Relaxation-API utilizing only one device.

    However wait, there’s 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 essential.

    CSV
    Determine 1. CSV File

    You’ll be able to simply add the Public Workspace to Postman by way of the next hyperlink. This may help 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, will probably be robotically added. (see picture beneath)

    Public DNA Middle Use-Case API Assortment

    Postman Public Workspace
    Determine 2. Postman Public Workspace

    We hold 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 the moment a number of collections and an surroundings.

    Use Circumstances

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

    The varied matters/use-cases we are going to contact on and deploy inside 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 units
    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 acquire a sensible understanding of the steps related to using Relaxation-API whereas organising a DNA Middle and an surroundings to help complicated, superior, common templates to ship gadget configuration throughout these labs. The labs goal to help engineers in quickly starting to make use of DNA Middle 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 embody configurations for numerous use circumstances. Lastly, this surroundings will allow engineers to cut 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 help you use them as you please inside the time scheduled. As well as, this permits us a spot to begin practising numerous ideas with out concern of impacting manufacturing environments.

    Because of this, we hope to demystify a few of the complexities of organising automation and assist information clients by way of the caveats. Due to this fact, to help clients within the transition towards automation, we’ve got 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 may obtain and develop from. As well as, the pattern templates and JSON recordsdata equipped are for simple import into DNA Facilities’ template editor for faster adoption. Lastly, some scripts are ready-made excerpts of code that help you construct the surroundings 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 numerous 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?
