Tanzu Kubernetes Grid (TKG) Demo Appliance for VMC and vSphere

by // 8 Comments

As some of you can probably tell from my recent Twitter updates and blog posts (here and here) that I have been spending some time lately with both vSphere with Kubernetes and Tanzu Kubernetes Grid (TKG). Like many of you in the community, I am still pretty new to Kubernetes (K8s) and I am still learning about what it has to offer both from an infrastructure standpoint but more importantly how it can be used to deliver new and modern applications. I am also very lucky to be part of the the VMware Event Broker Appliance Open Source Fling project which builds and runs on top K8s and this project has allowed me to really get hands on which is how I learn best.

A couple of months back I was asked to put together a workshop to demonstrate how to deploy TKG Clusters running on VMware Cloud on AWS (VMC) and while developing the workshop, I thought it would be really cool if I could make it even easier for anyone that is brand new to K8s to quickly get started with TKG. I wanted to have a solution that can literally be dropped into any supported vSphere-based environment with basic networking to go from Zero to Kubernetes in less than 30 minutes!

Enter the Demo Appliance for Tanzu Kubernetes Grid (TKG) Fling

A Virtual Appliance that pre-bundles all required dependencies to help customers in learning and deploying standalone Tanzu Kubernetes Grid (TKG) clusters running on either VMware Cloud on AWS and/or vSphere 6.7 Update 3 environment for Proof of Concept, Demo and Dev/Test purposes. This appliance will enable you to quickly go from zero to Kubernetes in less than 30 minutes with just an SSH client and a web browser!


In addition to the appliance, I have also put together a step by step workshop-style guide which not only walks you through in deploying your first TKG Cluster but also provide some example demos and references which you can explore further. Below are some of the highlights of the Demo Appliance for TKG:

Virtually Speaking Podcast: MacOS Virtualization and MacStadium

by // Leave a Comment

Last week I had the pleasure to be on the Virtually Speaking Podcast (#1 Virtualization Podcast) to talk a little about the history and the use cases driving MacOS Virtualization in the Enterprise. In fact, this affects most if not every single organization that develops either an Apple MacOS and/or iOS application which includes VMware.

We also had a very special guest, Preston Lasebikan, a Systems Architect for MacStadium who gave us some insights into how they are supporting major Enterprise customers such as Dropbox, Capital One, Shopify, Box and many others using their Apple Mac Infrastructure which runs on VMware vSphere. If you never heard of MacStadium before, they are the largest service provider of Apple Mac Infrastructure as a Service in the world and there is a high probability your organization is already using them with you even knowing.

Configure non-secure Harbor registry with Tanzu Kubernetes Grid (TKG)

by // 5 Comments

In an earlier blog post, I shared the steps to to configure Harbor with a proper signed SSL certificate that would serve as  private container registry for Tanzu Kubernetes Grid (TKG) CLI running in an air-gapped environment.

Although Harbor can easily be configured to support custom CA signed certificate, self-sign certificate and even just using HTTP, there are several additional steps and dependencies that is required if you wish to use a non-secure container registry with TKG CLI. This definitely was a bunch of trial/error and hopefully this can be made easier in the future to easily enable non-secure registry support with TKG CLI out of the box for development and testing purpose.

I also want to give a huge thanks to Jun Wang from our Modern Application Business Unit (MAPU), he was instrumental in helping me out and ultimately his tip on updating the containerd configuration was the last piece to the puzzle so that the K8s images deployed would use our insecure Harbor registry for pulling container images.
