Automate Inventory of vSphere Supervisor Clusters & vSphere Kubernetes Service (VKS) Guest Clusters

by // Leave a Comment

As customers begin planning their upgrade to VMware Cloud Foundation (VCF) 9.1, vSphere Supervisor and vSphere Kubernetes Service (VKS) have been coming up more frequently in upgrade discussions.

Before you can determine the applicable upgrade path, it is important to understand what has been deployed. Depending on your environment, you may have multiple vSphere Supervisor Clusters running different Supervisor versions, VKS Service versions, and VKS Guest Cluster versions, which can make gathering a complete inventory challenging.

To help simplify the collection of information, I have created a small PowerCLI script called Get-vSphereSupervisorAndVKSInventory.ps1 (I actually had to create the initial base with me verifying specific cmdlets to provide to AI because it went on wild tangent when asked to create me such a script) which will automatically inventory your vSphere Supervisor and VKS deployments. At first, I was hoping AI could

Disabling or deactivating vSphere Supervisor can take some time depending on the number of resources you may have deployed, which all need to be properly cleaned up.


In case the removal is taking longer than expected, there is not much information provided to the user in the vSphere UI.

However, I recently learned about a useful way to understand what is actually happening on the backend by looking at the vSphere Supervisor service logs, especially if you believe the operation is "stuck", which ended up being my situation.

Dynamically Rebalance or Evacuate VKS Control Plane / Worker Nodes across vSphere Zones in VCF 9.0

by // 2 Comments

vSphere Zones in VMware Cloud Foundation (VCF) 9.0 have been enhanced to offer greater flexibility in resource consumption and isolation for both vSphere Supervisor Control Plane VMs (Management), vSphere Kubernetes Service (VKS) Cluster (Workloads) or a combination of the two.


Depending on your required level of management availability and workload isolation, administrations have several vSphere Supervisor Zone deployment options to select from:

Note: The management zone selection (single vs multi) is only configurable during the initial enablement of vSphere Supervisor. It is currently NOT possible to reconfigure the vSphere Supervisor to switch from a single to multi-zone management without re-deploying vSphere Supervisor.
