How to deploy Tanzu Kubernetes Grid (TKG) Cluster with Antrea CNI 

by // 1 Comment

I have been working with Tanzu Kubernetes Grid (TKG) quite a bit lately and using their new slick TKG CLI for deploying standalone Tanzu Kubernetes Clusters (TKC) which can run in both VMware Cloud on AWS as well as your on-premises vSphere 6.7 Update 3 environment. If you have vSphere 7 and the vSphere with Kubernetes capability, it also supports TKG deployments natively as part of that solution but you can also use TKG CLI to deploy TKC's.

Out of the box, TKG includes all the necessary software components to deploy a production grade, upstream and conformant Kubernetes distribution. For most customers, the "batteries included" type of offering is more than sufficient but for some customers who may wish to customize some of these components further when running the standalone distribution. One such example is swapping out the default Container Network Interface (CNI) which uses Calico for a different CNI with more capabilities.


As you may have guess from the title of this post, we will be replacing Calico with Antrea which is another open source CNI. In fact, Antrea was started by VMware last year and uses Open vSwitch (OVS) to provide network and security capabilities to Kubernetes. You can read more about Project Antrea here and more details about its architecture can be found here.

Disclaimer: This is currently not officially supported by VMware. I do know the TKG team is looking at Antrea support in the future.

Automated vSphere 7 and vSphere with Kubernetes Lab Deployment Script

by // 117 Comments

I know many of you have been asking me about my vSphere with Kubernetes automation script which I had been sharing snippets of on Twitter. For the past couple of weeks, I have been hard at work making the required changes between the vSphere 7 Beta and GA workflows, some additional testing and of course documentation. Hopefully the wait was worth it (I think it is) and if you enjoy the script or have benefited, please consider adding 🌟to the Github repo to show your support! Thanks and enjoy

The Github repository:

Before getting started, please carefully read through the requirements section along with the complete sample end-to-end execution if you are new to vSphere with Kubernetes. You will need to have a VMware Cloud Foundation (VCF) 4.0 license before you can get started and specifically an NSX-T Advance license which is one of the required parameters within the script. If you do not have access to a VCF 4 license, I strongly recommend taking part in the recent VMUG Advantage Homelab Group Buy effort which I had started to easily get access to the latest VMware releases along with a nice 15% discount!

The script supports deploying both a standard vSphere 7 environment with just VCSA, ESXi and vSAN as well as the complete solution which includes NSX-T to support vSphere with Kubernetes. For more details, please refer to the FAQ.

New vCenter events for vSphere 7, VMware Cloud on AWS 1.10 and vSphere with Kubernetes

by // Leave a Comment

Last year I published a Github repo which lists all the vCenter Server Events for a default installation for both vSphere 6.7 Update 3 and VMware Cloud on AWS 1.9. Since every vSphere environment is going to be unique with various 2nd and 3rd party solutions, I have also included a small PowerCLI script in the blog that you can use to generate the list of events for your own deployment.

With the release of vSphere 7 and VMware Cloud on AWS 1.10, I thought it was time to update the repo to see what's new which can be useful in a number of scenarios including using these events with the popular vCenter Event Broker Appliance (VEBA) Fling.

One thing worth pointing out with the introduction of vSphere with Kubernetes in vSphere 7, is there are also specific vCenter events, a total of 23 that are available and I am sure more will come in the future. Below is a quick summary which is also included in the Github repo.
