4.8(700)176 pagesPublished 2026

Harbor is an open-source registry for container images and cloud-native artifacts that adds security and governance on top of storage. This free book teaches it from the ground up: container registries and the OCI distribution model, Harbor's architecture and components, projects and access control with RBAC, SSO, and robot accounts, vulnerability scanning and policy enforcement, image signing and content trust, replication across registries and clouds, management with quotas/retention/garbage collection, Harbor in Kubernetes and CI/CD as the secure image gate, and securing and operating Harbor in production. Ten focused chapters with clear diagrams that show how to turn a registry into a trusted, governed hub for your software supply chain.
