Enabling new vSphere Kubernetes Service (VKS) Cluster Management for VCF Automation (VCFA)

by // Leave a Comment

As of VMware Cloud Foundation (VCF) 9.0.1, users can now manage the full lifecycle of their vSphere Kubernetes Service (VKS) Clusters, including backup and restore, using the new vSphere Kubernetes Service Cluster Management (VKSM) capability, natively integrated into VCF Automation (VCFA).


This is definitely a must have capability for users managing dozen or even hundreds of VKS Clusters across different versions, VKSM provides the easy button for platform operators!

I figured before going on PTO next week and shutting down my lab, this would be the perfect time to get this deployed in my lab ... what could go wrong, right!? 😅

Quick Tip - Configuring vSphere Kubernetes Service (VKS) Cluster with self-signed container registry

by // Leave a Comment

Over the weekend, I had finished building a small container application that I had developed on my local desktop, which worked great. However, the real test was to deploy the application on a vSphere Kubernetes Service (VKS) Cluster, which would require the container image to be hosted in a container registry.

Rather than using a public container registry, like many organizations, you typically would setup an internal registry that your infrastructure could have access to. Harbor is my go to container registry and is extremely simple to setup as it uses docker-compose under the hood.

After uploading my container image to Harbor, if you try to deploy it to your VKS Cluster, you will immediately see the following image pull error:

tls: failed to verify certificate: x509: certificate signed by unknown authority


Just like any system that attempts to connect to an endpoint with a self-signed TLS certificate that it can not verify, it will not trust which is the default behavior.

For our VKS Cluster to be able to successfully pull an image from Harbor with a self-signed TLS certificate, we need to add the trusted CA to our vSphere Namespace and then reference that as part of our VKS Cluster deployment.

MS-A2 VCF 9.0 Lab: Configuring vSphere Kubernetes Service (VKS)

by // Leave a Comment

This post is part of a short series that builds on our minimal VMware Cloud Foundation (VCF) 9.0 deployment (2x Minisforum MS-A2) and showcases how to fully leverage the exciting new capabilities in the VCF 9 platform, all while maintaining a minimal resource footprint, which is ideal for lab and learning purposes.

In this blog post, we will explore one of the foundational vSphere Supervisor services called vSphere Kubernetes Service (VKS), enabling administrators to easily deploy, manage and lifecycle conformant Kubernetes Clusters at scale for their development and platform teams. VKS can be consumed through vCenter Server for single IT organizations, as well as through VCF Automation for organizations that require strong multi-tenancy, including cloud service providers.


Here are some additional VKS Resources that might be of interests if you would like to learn more:
