An architect gathered the following requirements for a Supervisor image store.

The VMware Cloud Foundation 9.0.2 Design Guide identifies Harbor as the enterprise-grade container registry integrated with vSphere with Tanzu and Supervisor Clusters. It states:

“Harbor provides a cloud-native registry that supports image scanning, replication, and image signing. It is the recommended solution for storing, securing, and distributing container images within VCF environments.”

Harbor integrates with vSphere Namespaces and supports content trust, vulnerability scanning, and image replication across multiple sites — capabilities not available with Docker Hub or Gitea, and only partially supported in Azure ACR.

Therefore, Harbor is the correct and VMware-recommended component for a Supervisor image store that requires enterprise security and replication capabilities.
