harbor
Alternative to GitHub
Harbor is a registry for secure storage and distribution of container images. With integrated vulnerability scanning, signature verification, and access control, it supports enterprise container workflows.
- Vulnerability scanning via Trivy integration for automatic image security scanning
- Content signing with Cosign/Notary v2 for image signature and verification
- Role-based access control with granular per-project permission management
- Replication for image synchronization across multiple Harbor instances
- Proxy cache for caching external registries like Docker Hub
- Helm chart management alongside container images
Built in Go as a CNCF graduated project, Harbor serves as the enterprise standard for running private container registries with security-first operations as a Docker Hub alternative.
