VCF 9.0 documents that you obtain access to the Supervisor (and the contexts you’re entitled to, which commonly correspond to namespaces and workload clusters) by authenticating withkubectl vsphere login. The procedure “Get and Use the Supervisor Context” explains that after you log in, a Kubernetes configuration context is generated and you can view it in$HOME/.kube/config, which is “commonly called the kubeconfig file.”

The documentation is explicit that running kubectl vsphere login --server= < KUBERNETES-CONTROL-PLANE-IP > --vsphere-username < VCENTER-SSO-USER > “creates a configuration file with the JSON Web Token (JWT) to authenticate to the Kubernetes API,” and then lists how to view and switch contexts using kubectl config get-contexts and kubectl config use-context.

This matches optionDprecisely: you don’t “download” kubeconfig from VCF Operations or a Supervisor Services page; instead, you generate/update your kubeconfig locally by logging in withkubectl’s vSphere plugin, which writes the required cluster/user/context details into .kube/config.

Hosts and Clusters

To create avSphere Zone(used as a Supervisor Management Zone and/or Workload Zone), the administrator must start from the vSphere Client inventory wherevCenterand its clusters are managed. That’s why the correct starting point in the “Inventories” toolbar isHosts and Clusters—it is the entry point used to select the vCenter object and the target clusters.

VCF 9.0 documents the zone-creation workflow as:navigate to vCenter, thenSelect Configure, thenselect vSphere Zones, and finally clickAdd New vSphere Zone. After naming the zone, youselect a vSphere cluster to add to the zoneand finish the wizard.

This sequence matches the intent of the hotspot: you must first open the inventory view that exposes vCenter and clusters (Hosts and Clusters), then perform the configuration steps under vCenter to define vSphere Zones. Once created, these zones can later be selected during Supervisor deployment (for multi-zone placement) or assigned to namespaces for workload placement.

VCF 9.0 design guidance for theSupervisor NSX Load Balancer modelstates that theNSX load balancers run on NSX Edges, and sets explicit sizing requirements at theEdge nodelevel. In the “NSX Load Balancer Design Requirements,” VCF 9.0 requires that theNSX Edge cluster must be deployedbecause “NSX Load Balancers run on NSX Edges.” It further requires that“NSX Edge nodes must be deployed with a minimum of Large form factor”because NSX load balancers havefixed resource allocations on NSX Edge nodes, and the Large form factor is needed to accommodate basic system and workload needs.

This directly ties “deployment size” of the load balancer service capacity to theEdge node form factor(Small/Medium/Large, etc.) rather than the number of pods or the number of clusters. The document also notes that if additional load balancers are required, NSX Edges can bescaled up or out, again reinforcing that sizing is anEdge nodesizing decision.

VKS cluster lifecycle is managed using adeclarative API: you usekubectl with a YAML fileto specify the desired state of the cluster (for example: “how many nodes,” Kubernetes version, sizing, and storage). After the cluster is created, youupdate the YAMLto update the cluster. This is why the correct operational approach is to modify the cluster manifest (cluster.yaml) rather than deleting and redeploying.

Additionally, VKS uses multiple controller layers, whereCluster APIand theVirtual Machine Serviceare responsible for provisioning and managing the lifecycle of the control plane and worker node VMs that make up the VKS cluster. In other words, when you change the declared state for control plane sizing/replica count in the cluster YAML, the platform reconciles to that new state by adjusting the underlying control plane VMs through the supported controllers, instead of requiring disruptive “tear down and rebuild” operations.

So, editing the cluster.yaml to adjust the control plane replica count is the method that matches the documented VKS declarative operations model and controller-driven reconciliation.
