VKS Upgrade Failure: "NOT_FOUND" Error for Image Bundles

Products

• VMware vSphere Kubernetes Service

Issue/Introduction

• In the vSphere Client, the Supervisor cluster upgrade appears stuck during an attempt to upgrade.
• When checking the configured core supervisor services, the tkg.vsphere.vmware.com service shows a ReconcileFailed status with the following error message:
  
  vendir: Error: Syncing directory '0': Syncing directory '.' with imgpkgBundle contents: Fetching image: GET https://: NOT_FOUND: artifact not found .

Environment

VMware vSphere Kubernetes Service

Cause

Missing service manifest tags and image bundles within the local Harbor registry, causing the Supervisor cluster to fail reconciliation.

Resolution

To resolve this issue, you must ensure that the target version's image bundles are fully populated in your local registry.

1. Inspect Harbor Registry: Check Harbor UI for missing tags associated with the targeted VKS version.
2. Import Assets: Manually upload the missing image bundles and manifest tags to the Harbor registry.
3. Update Configuration: Ensure that the Supervisor Cluster Image Registry settings in vCenter or any related PKG configuration files are pointing to the correct local repository paths. Once the images are successfully uploaded, the Supervisor cluster should automatically retry and complete the reconciliation.
