Overview
Harbor is a CNCF-graduated open-source container image registry that adds enterprise features on top of the standard Docker Registry. It provides role-based access control, vulnerability scanning via integrations with Trivy or Clair, image signing with Notary, replication between registry instances, and a web UI for managing projects and users. Harbor is typically deployed using Docker Compose for smaller setups or Helm charts for Kubernetes environments in production.
Where it falls short of Dropbox
- Scoped to container/OCI artifacts only; not a general-purpose file storage solution
- High operational overhead; requires PostgreSQL, Redis, and careful networking configuration
- Upgrade process between major versions can be complex and error-prone
- Managed cloud registries (ECR, GCR, ACR) offer tighter CI/CD integrations out of the box
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
