Documentation

The purpose of this website is to provide an overview of various Kubernetes networking components with a specific focus on exactly how they implement the required functionality.
The information here can be used for educational purposes, however, the main goal is to provide a single point of reference for designing, operating and troubleshooting cluster networking solutions.
Warning This is not a generic Kubernetes learning resource. The assumption is that the reader is already familiar with basic concepts and building blocks of a Kubernetes cluster – pods, deployments, services.

Introduction K8s is already a crucial part in the VMware ecosystem for many years and the level of integration in other products like NSX and AVI changed a lot in the past. That is also true for the naming like “vSphere with Tanzu”, “vSphere IaaS” and “VKS” and perhaps more changes in the future. For this blog post we will bring some spotlight to the integration for VKS with NSX VPCs, which is from my point of view a great enhancement from tenancy point of view.

Introduction Some of you are using NSX for many years already and are aware of the different changes and improvements implemented in the last years. I personally started with NSX in version 2.3 and one of the first important improvements I recognized is “MultiTEP” for edge nodes from type VM. It was released with NSX 2.5 and officially added to the reference design guide.
By the way: The reference design guide is still a great resource to learn the design pricipals for NSX implementaions. This is especially interesting for those who might be new to NSX.
