This guide explains why the original Harbor server needed to be taken offline, walks through setting up a new Harbor instance, and details the step‑by‑step configuration of source and replication repositories plus enabling the replication rule to synchronize images.
This guide walks you through configuring Harbor and Docker Registry replication, covering background considerations, creating replication repositories and rules, manual sync triggers, and reference resources, so you can keep container images up‑to‑date and secure.
Harbor is an enterprise‑grade Docker image registry that adds role‑based access control, policy‑driven replication, vulnerability scanning, LDAP/AD authentication, garbage collection, Notary signing, a web UI and RESTful API, and supports HA deployments, automated cleanup, OA integration, and flexible CI/CD workflows for secure, scalable image management.
This article explains the design and implementation of Harbor's policy‑based Docker image replication, detailing its architecture, job service workflow, state‑machine handling, and how it reduces storage‑specific dependencies while simplifying large‑scale container registry synchronization.
