Harbor is vmware's open source enterprise docker registry project Harbor's advantages Role-based control Mirror-based replication strategy Support LDAP/AD image deletion and garbage collection Graphical UI audit RESTful API Harbor architecture Composition Proxy: Unified acceptance of browser, docker client requests through a front-end reverse proxy, and forward the request to different back-end services Registry: responsible for storing Docker images, and processing docker push/pull commands Core services: Harbor core functions, including UI, webhook, token services Database: provides database services for core services Log collector: responsible for collecting logs of other components for future analysis Docker private repository architecture topology

Proxy: A front-end reverse proxy uniformly accepts requests from browsers and Docker clients and forwards the requests to different back-end services. Registry: responsible for storing Docker images and handling docker push/pull commands. Core services: Harbor's core functions, including UI, webhook, token services. Database: Provides database services for core services. Log collector: responsible for collecting logs of other components for later analysis.

 The user requests to access Core services through Proxy reverse proxy, UI provides web interface, token token, after your first login, the server will give you a string of serial number, next login directly, you need to download the image information, attributes, are stored in the database behind, and then through the webhook callback to the registry private repository to retrieve the image. This series of operations is stored in the log.
