In VCF 9.0, ingress is described as part ofVKS cluster networking. The documentation’s VKS Cluster Networking table lists“Cluster ingress”and identifies its role asrouting inbound pod traffic. It further clarifies that this function is delivered by athird-party ingress controller, and explicitly namesContouras an example (“you can use any third-party ingress controller, such as Contour”).

That mapping is exactly what optionAdescribes: Contour is deployed to provideingresscapabilities so that inbound requests from outside the cluster can be routed to Kubernetes services and pods according to ingress rules. In other words, Contour is not a storage component (that would align to CSI/CNS/pvCSI), not a node lifecycle manager (that is handled by VKS/Cluster API/VM Service), and not an infrastructure health monitoring tool (that would be metrics/observability tooling). VCF 9.0 positions Contour specifically within theingresspart of the networking feature set, makingAthe correct answer.

The documented behavior of kubectl edit is that it opens the object manifest in a local text editor, and the editor it launches is controlled by environment variables. In the VCF 9.0 documentation (Workload Management / Supervisor operations), the procedure explicitly states: “The kubectl edit command opens the namespace manifest in the text editor defined by your KUBE_EDITOR or the EDITOR environment variable.”

If the administrator’s environment does not have KUBE_EDITOR or EDITOR defined (or they point to an invalid/interactive-less editor in the current session), kubectl edit may not open the expected editor workflow, and the admin may not see the normal confirmation after saving and exiting. Setting KUBE_EDITOR (preferred for kubectl-specific behavior) or EDITOR ensures kubectl launches a known-good editor, allowing the manifest to be modified, saved, and then submitted back to the API server when the editor exits. The same documented requirement also applies to editing other Kubernetes objects (such as a VKS cluster manifest) because the kubectl edit mechanism is identical.

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.

The error shows an admission webhook denial wherevariable validation failedand multiple entries under spec.topology.variables[...] are reported as“variable is not defined”. That message indicates the manifest is supplying variables that arenot part of the current Cluster API / topology schemaenforced by the Supervisor during cluster creation. In VKS, cluster provisioning isdeclarative: you invoke the VKS API withkubectl + a YAML file, and “after the cluster is created, you update the YAML to update the cluster.” When the API/schema changes between releases, older manifests can contain fields/variables that are no longer recognized, and the admission webhook blocks them to prevent creating an invalid cluster spec.

This aligns with VMware’s broader direction that the olderTanzuKubernetesCluster (TKC) API was deprecatedand customers are encouraged to useCluster APIfor bootstrap/config/lifecycle management. In practice, to complete the upgrade/creation successfully, you must update the cluster manifest to match the supported schema:remove the deprecated/unknown topology variablesshown in the error (for example, the undefined storage-policy and trust variables) and re-apply the correctedworkload.yaml.
