How to Set Up Docker Registry with Harbor

Harbor is an open-source container registry that provides image management, vulnerability scanning, and access control. Run your own private registry on a Breeze server to keep container images close to your infrastructure.

Prerequisites

• A Breeze instance with at least 4 GB RAM and 40 GB disk
• Docker and Docker Compose installed
• A domain name with SSL certificate

Configuring Harbor
