In Workload Management, updating the Supervisor and updating VKS clusters are related but distinct lifecycle operations. The Supervisor runs its own Kubernetes distribution, while VKS clusters consume vSphere Kubernetes releases (VKrs). These are “delivered differently,” with Supervisor Kubernetes releases and VKrs each having their own release cadence and compatibility constraints. As a result, successfully updating the Supervisor control plane does not automatically change the Kubernetes version running inside an existing VKS workload cluster; the VKS cluster must be updated to a compatible VKr separately. This mismatch is exactly why an application can still fail after a Supervisor update: the DevOps engineer is still deploying onto a cluster that hasn’t been updated to the Kubernetes version required by the application (or by the API versions/features it depends on). Additionally, Workload Management enforces sequential minor-version updates and compatibility checks between Supervisor and VKrs, so the correct remediation is to update the VKS cluster to an appropriate VKr that satisfies both application needs and Supervisor compatibility.

Log in to the Supervisor as an administrator.

Run kubectl to look up the updatejob_name.

Run kubectl proxy so that curl can be used to issue requests.

Use curl to issue a patch command to clear the .status.conditions on the Job controller.

In VMware Cloud Foundation (VCF) 9.0, managing Tanzu Kubernetes Clusters (TKC) through the vSphere Kubernetes Service (VKS) involves a declarative lifecycle managed by the vSphere Supervisor. When a TKC upgrade enters an upgradefailed state, it is typically because the underlying cluster reconciliation logic has hit a terminal error or a timeout within the Cluster API (CAPI) controllers. To resolve this, an administrator must interact directly with the Supervisor’s API server to reset the state of the upgrade job.

The troubleshooting workflow begins with authenticating to the Supervisor cluster using the kubectl vsphere login command (Step B). Once authenticated and the context is set to the correct namespace, the administrator must identify the specific job responsible for the upgrade failure by querying the namespace for job resources (Step D). Because the Supervisor API requires specific authentication tokens that are complex to manage via standard CLI tools for manual JSON patching, running kubectl proxy (Step A) is the standard procedure to create a local gateway. This allows the administrator to use a simple curl command (Step C) to send a JSON Merge Patch to the API server. The critical step is clearing the .status.conditions field. By removing the " Failed " condition, the Supervisor ' s controller-manager is triggered to re-evaluate the desired state and attempt the upgrade process again. This sequence ensures the declarative engine can resume operations without requiring a full cluster redeployment.

In VCF 9.0 Workload Management, workload backup for VKS clusters (and vSphere Pods) is performed using Velero, specifically theVelero Plugin for vSpherefor Supervisor/VKS scenarios. The documentation describes that you must firstprovide an S3-compatible object storeas part of installing and configuring the Velero Plugin for vSphere, because backup data (Kubernetes metadata and volume snapshot data movement) relies on object storage rather than “namespace storage.” The backup workflow further indicates that when you create a backup, the system uploadsKubernetes metadata to the object store, and persistent volume snapshot handling is coordinated through the plugin components (Snapshot/Upload custom resources).

Therefore, the correct configuration pattern is to point Velero’s backup target (BackupStorageLocation) at anS3-compatible object storeendpoint so metadata and snapshot payloads have a durable destination. This aligns with the documented prerequisite that object storage is required to enable backup/restore operations for persistent workloads, and it is the mechanism Velero uses to store backup artifacts for later restore operations in VKS environments.
