Project Harbor is an an open source trusted cloud native registry project that stores, signs, and scans content. Harbor extends the open source Docker Distribution by adding the functionalities usually required by users such as security, identity and management. Having a registry closer to the build and run environment can improve the image transfer efficiency. Harbor supports replication of images between registries, and also offers advanced security features such as user management, access control and activity auditing.

Harbor is hosted by the Cloud Native Computing Foundation (CNCF). If you are an organization that wants to help shape the evolution of cloud native technologies, consider joining the CNCF. For details about who's involved and how Harbor plays a role, read the CNCF announcement.

• Role based access control: Users and repositories are organized via 'projects' and a user can have different permission for images under a project.
• Policy based image replication: Images can be replicated (synchronized) between multiple registry instances, with auto-retry on errors. Great for load balancing, high availability, multi-datacenter, hybrid and multi-cloud scenarios.
• Vulnerability Scanning: Harbor scans images regularly and warns users of vulnerabilities.
• LDAP/AD support: Harbor integrates with existing enterprise LDAP/AD for user authentication and management.
• Image deletion & garbage collection: Images can be deleted and their space can be recycled.
• Notary: Image authenticity can be ensured.
• Graphical user portal: User can easily browse, search repositories and manage projects.
• Auditing: All the operations to the repositories are tracked.
• RESTful API: RESTful APIs for most administrative operations, easy to integrate with external systems.
• Easy deployment: Provide both an online and offline installer.

System requirements:

On a Linux host: docker 17.03.0-ce+ and docker-compose 1.10.0+ .
