Harbor

What is Harbor?

Harbor is an open source cloud native image registry designed for storing, signing, and scanning container images. Built with Kubernetes environments in mind, Harbor serves as a trusted repository solution for organizations managing containerized applications at scale. The platform provides core functionality for container image management, including secure storage, content signing for image authenticity, and vulnerability scanning capabilities. Harbor is particularly suited for DevOps teams and organizations implementing CI/CD pipelines that require centralized control over container artifacts. As an open source project hosted on GitHub, Harbor allows teams to self-host their registry infrastructure, providing an alternative to cloud-hosted solutions. The registry integrates with Kubernetes workflows and supports common container image formats and standards. Harbor addresses security and compliance requirements through image scanning features and signing capabilities, helping teams maintain visibility into their container supply chain. The platform is maintained by an active community and emphasizes production-grade reliability through comprehensive testing and adherence to security best practices. Ideal for enterprises and development teams seeking a self-managed, feature-rich container registry solution, Harbor eliminates vendor lock-in while providing the functionality needed to manage container images across development, testing, and production environments.
