This weblog is a collaboration between lead creator Quinn Snyder, Developer Advocate, Cisco DevRel and Ravi Balakrishnan.
You’ve heard for a number of years how the Cloud Networking (CN) crew within Cisco has been remodeling the operation, administration, and observability of the trendy datacenter. From new platforms and purposes to new methods by which a number of materials and clouds will be bridged collectively, the CN crew has put in a ton of effort into making datacenter networking as easy as doable regardless of the way you select to handle your platforms, by means of UI, API, or leveraging Infrastructure as Code (IaC) tooling.
Cisco Developer Relations (DevRel) is dedicated to creating certain that we proceed every BE’s design and engineering ethos ahead after we create labs, pattern code, and sandboxes. In reviewing all of the work that the CN crew has executed, one factor stands out above all others – the eye to element spent by engineering on creating, testing, and validating Ansible modules and Terraform suppliers for the merchandise throughout the CN portfolio. We needed to make it possible for DevRel work was front-and-center in all the things doable, and since there are many assets on the market, a weblog submit summarizing and highlighting it will be significant.
Highlighting all of the IaC efforts can be infructuous if we didn’t have a spot the place customers and practitioners might go to learn to use IaC ideas with their CN controllers and purposes. To attain this goal, we now have created guided studying labs that target foundational studying and focused use-cases for a given platform or know-how. Every of those lab modules is grouped by know-how, explaining the construction of the IaC file, the way it accomplishes the duty, and methods by which the outcomes of the change will be verified by means of output or by means of UI interactions (belief, however confirm is vital once you’re studying). Every studying module additionally consists of hyperlinks to a public repository holding pattern code – permitting you to deal with the IaC DSL, moderately than copying and pasting and hoping one thing works.
When you’ve got frequented the DevNet Studying Modules and Tracks earlier than, it’s possible you’ll acknowledge that the underside two modules, targeted on DCNM, haven’t been talked about earlier than, and also you’d be right. These modules had been launched over the summer time and are targeted on utilizing IaC to work together with DCNM for frequent duties related to VXLAN-EVPN materials.
There are additionally singular labs created outdoors of a observe that cowl extra advanced or ad-hoc matters. One of the vital common ones up to now has been the usage of service metadata from HashiCorp Consul to feed into an IaC module pushed by Terraform to mechanically scale safety infrastructure inside Cisco ACI. Yow will discover that singular lab right here
Whereas indirectly tied to IaC, everyone knows you can’t simply run some code in a manufacturing setting and cross your fingers that it really works; constructing an agile infrastructure tradition takes a lot of testing in mock environments. We acknowledge that many organizations undergo from this lab setting hole and search to make sure that nobody is ever with out API and programmability-enabled sandboxes, reservable and personal to you at your time of want. These sandboxes are up to date with present and supported variations of the platforms used, making certain that you’ve got entry to the present apps and APIs. To coincide with the checklist of IaC Studying Tracks supplied above, a few of the sandboxes that may very well be used are:
The keen-eyed will once more spot that the final sandbox in that checklist is new, or no less than an up to date model of a earlier sandbox. The newest Nexus Dashboard Orchestrator (NDO) sandbox is operating on Nexus Dashboard 2.2 – unlocking the potential to not solely work with the Orchestrator APIs, but in addition the foundational platform APIs. As practitioners, we’re not restricted to uncooked API interactions with ND – however we will use IaC tooling such because the Ansible ND assortment to work with this new platform.
Typically, it’s good to have a single location or URL to entry all the data you must discover a couple of sure matter. For all issues IaC inside Cloud Networking – you merely need to hit the NexusAPI DevCenter accessible at https://developer.cisco.com/nexusapi. Right here, you’ll discover hyperlinks to all of the IaC labs, sandboxes, useful movies, hyperlinks to all of the IaC collections and suppliers, in addition to blogs and webinars that will help you down the trail to codify your infrastructure.
Lastly, in case you have any questions on any of the labs, sandboxes, or the DevCenter, please attain out to us. Quinn and Ravi are on Twitter @qsnyder, @RaviBala8 and we’d be more than pleased that will help you or level you within the route of somebody who can.
