Storage

Resources

When a stateful pod (like Harbor’s database) is stuck Pending/ContainerCreating or repeatedly failing to attach/mount storage, one of the first checks is whether the PVC’sAccess Modesmatch what the workload and backing storage support (for example, ReadWriteOnce vs ReadWriteMany). In Kubernetes, the PVC and PV explicitly showAccess Modes(for example Access Modes: RWO) when you inspect them.

In the vSphere Namespace UI, theStoragetab is where namespace storage is managed and reviewed (including storage policy assignments that back storage classes/PVCs), making it the natural place to validate the storage configuration being consumed by the Harbor database PVC. VMware’s VCF documentation directs administrators to navigate to a namespace and use theStoragetab for storage-related settings.

TheResourcestab is the Kubernetes-object oriented view for the namespace, where you can locate the PVC object associated with the failing pod and inspect its properties/YAML (including the requested storage class and access mode intent). Namespace permissions explicitly include the ability to view Kubernetes resources within the namespace, which aligns with checking PVC details there.

Kubernetes Service

When adding a Kubernetes cluster to anexisting vSphere Namespace, the workflow is initiated from within that namespace’s context in the vSphere Client. The administrator first opens the target namespace (as shown in the left navigation where the namespace is selected), then uses theKubernetes Servicearea to create and manage Kubernetes clusters associated with that namespace. In the namespaceSummaryview, theKubernetes Servicetile/card provides the entry point for cluster lifecycle actions, typically via an action link such asManage(and from thereCreate Cluster). This is because the Kubernetes cluster is anamespace-scoped resourcein the Supervisor environment: it inherits namespace-level policies and configuration such as permissions/RBAC, resource limits, storage policies, and networking selections that have already been defined for that namespace. Navigating to other areas likeStorageorNetworkis used to validate or adjust prerequisites (for example, storage policy availability or network settings), but the actual “create cluster” operation is launched fromKubernetes Servicewithin the namespace to ensure the cluster is created under the correct tenant boundary and governance model.

Answer (Correct Order):

Navigate in VCF Operations to Fleet Management → Tasks, select the instance and review Tasks

Check for errors or failed ClusterConfig objects

SSH into the Supervisor Cluster to review logs / attempt manual cleanup if required

Restart the WCP Service

To determinewhya Supervisor upgrade failed, you start where the platform records the most actionable failure context: themanagement-plane task history. The Fleet/Task view surfaces the upgrade workflow steps, timestamps, and the specific operation that failed, which gives you the fastest pointer to the failing phase (precheck, image staging, reconciliation, add-on updates, etc.). Next, you validate the Kubernetes-side reconciliation state by checking forfailed ClusterConfigobjects, because Supervisor enablement/upgrade actions commonly drive configuration via controller reconciliation; a failed ClusterConfig often contains the clearest “reason” and “message” fields that explain what blocked progress (validation errors, dependency issues, unreachable endpoints, incompatible components).

If the management-plane/task view and ClusterConfig status still don’t isolate the root cause, the next escalation is toSSH into the Supervisorto inspect component logs/events and identify low-level failures that may not bubble up cleanly (for example, admission failures, controller crashes, or connectivity/auth issues). Finally,restarting WCPis a remediation step that can clear stuck states, but it’s placed last because it can alter evidence and should not be your first action when you’re still trying to identify the original failure cause.

VCF 9.0 explains pod fundamentals by describing how Workload Management introducesvSphere Pods, stating a vSphere Pod is “equivalent of a Kubernetes pod” and that it “runs one or more Linux containers.” This directly eliminates optionB, because a pod can includeone or morecontainers (not only one).

The vSphere 9.0 documentation further defines a KubernetesPodas “a group of one or more containerized applications that share such resources as storage and network,” and notes the containers inside a pod are “started, stopped, and replicated as a group.” That definition reflects Kubernetes’ scheduling and lifecycle model: Kubernetes treats the pod as the primary unit it places and manages together, which is why a pod is regarded as thesmallest deployable unitfor running containerized workloads in Kubernetes. OptionsCandDare incorrect because pods are Kubernetes objects (not “managed by Docker” as a smallest entity), and Kubernetes abstracts the underlying runtime/host so pods are not defined as being “deployed directly on the virtual machine” as a characteristic.

Kubernetes Role-Based Access Control (RBAC) is implemented through theRBAC API group(rbac.authorization.k8s.io) and defines the core authorization primitives used to grant permissions to users, groups, and service accounts. The cluster-scoped objects declared by the RBAC API areClusterRoleandClusterRoleBinding. AClusterRoledefines a set of permissions (verbs such as get/list/watch/create/update/delete) over resources at thecluster scope(including cluster-wide resources and optionally namespaced resources across namespaces). AClusterRoleBindingthenbindsthat ClusterRole to a subject (user/group/serviceaccount), making those permissions effective cluster-wide.

This differs from namespace-scoped RBAC objects (RoleandRoleBinding) which apply only within a single namespace. The other options are incorrect becauseClusterObject/ClusterNodeare not RBAC API objects,ValidatingAdmissionPolicybelongs to the admission control API surface (policy enforcement),ResourceQuotais a namespace resource governance object, andContainer/Deploymentare workload/runtime concepts defined in the core/apps APIs rather than authorization primitives.

In VCF 9.0 VKS clusters, network policy is a core Kubernetes networking control implemented by the cluster’s CNI (Antrea or Calico). The VCF documentation’s “VKS Cluster Networking” table describesNetwork policyas the feature that “controls what traffic is allowed to and from selected pods and network endpoints,” and identifies Antrea or Calico as the providers for this capability. That definition precisely matches optionB: it governs pod-to-pod and pod-to-external endpoint communication rules. This is different from ingress routing (which the same table describes separately as “Cluster ingress … routing for inbound pod traffic”), so option C is not correct for “network policy.” It is also different from NodePort behavior (external access via a port on each worker node through the Kubernetes network proxy), which is explicitly listed as “Service type: NodePort.” Finally, creating/operating clusters natively in Supervisor is a broader lifecycle function (Cluster API/VKS API), not the definition of network policy. Therefore,NetworkPolicyis the Kubernetes-layer mechanism to define and enforce allowed traffic flows.

VCF 9.0 distinguishes betweenbacking up the Supervisor control planeandbacking up workloadsthat run on the Supervisor, includingvSphere Pods. In the “Considerations for Backing Up and Restoring Workload Management” table, the scenario “Backup and restore vSphere Pods” explicitly lists the required tool as“Velero Plugin for vSphere”, with the guidance to “Install and configure the plug-in on the Supervisor.”

The same document is explicit thatstandalone Velero with Restic is not valid for vSphere Pods, stating: “You cannot use Velero standalone with Restic to backup and restore vSphere Pods. You must use the Velero Plugin for vSphere installed on the Supervisor.”

vCenter file-based backup is documented for restoring theSupervisor control plane state, not for backing up and restoring vSphere Pod workloads themselves. Therefore, to meet the requirement to protect third-party applications running asvSphere Pods, the architect should propose theVelero Plugin for vSphere.

In VMware Cloud Foundation (VCF) 9.0, the provisioning of storage for vSphere Kubernetes Service (VKS) clusters follows a specific consumption model. The process begins with the vSphere administrator creating a Storage Policy within the vSphere Client using Storage Policy Based Management (SPBM) . This policy defines the performance, availability, and replication characteristics of the underlying datastores (such as vSAN or VMFS).

To make this storage available to VKS workload clusters, the administrator must assign the policy to the vSphere Supervisor Namespace . Once assigned to the namespace, the Supervisor automatically creates a corresponding Kubernetes StorageClass within that namespace. When a developer or administrator later defines a Tanzu Kubernetes Cluster (VKS) in that same namespace, they reference this StorageClass in the cluster ' s YAML specification for its control plane and worker nodes. This architecture ensures a clean separation of concerns: the vSphere administrator manages the physical storage tiers and policies, while the DevOps user consumes them as native Kubernetes objects. Assigning the policy directly to a cluster (Option C or D) is not supported in the VKS architecture, as all resource allocations—including compute, memory, and storage—must be mediated through the Supervisor Namespace to ensure proper multi-tenancy and resource quota enforcement within the VCF environment.
