Harbor is an open-source registry that secures artifacts with policies and role-based access control, ensures images are scanned and free from vulnerabilities, and signs images as trusted. Harbor, a CNCF Graduated project, delivers compliance, performance, and interoperability to help consistently and securely manage artifacts across cloud native compute platforms like Kubernetes and Docker.
Harbor Advantages
- Harbor supports images replication to replicate repositories from one Harbor instance to another.
- Harbor provides labels to isolate image resources globally or at the project level.
- Users and repositories are organized into projects. Users can have different permissions for the images in different projects.
- Images can be synchronized between multiple registry instances with auto-retry on errors, offering support for load balancing, high availability, multi-datacenters, hybrid, and multi-cloud scenarios.
- Harbor uses Aqua & Trivy to scan images regularly and warn users of vulnerabilities.
- Images can be deleted, and their space can be recycled.
Harbor Workflow
[us_image image=”103990″ size=”full” link=”%7B%22url%22%3A%22%22%7D”]Aqua helps to stop attacks on cloud native applications and prevent them before they happen, stop them as they happen.
Trivy is the most popular open-source security scanner, reliable, fast, and easy to use. Use Trivy to find vulnerabilities &IaC misconfigurations, SBOM discovery, Cloud scanning, Kubernetes security risks and more.
