Harbor
Self-HostedOpen-source container registry with enterprise-grade security features
Overview
Harbor is an open-source, CNCF-graduated container registry designed to store, sign, and scan container images with enterprise-grade security. It supports Kubernetes integration via Helm charts, offers role-based access control (RBAC), OIDC authentication, vulnerability scanning (Trivy integration), and image replication across registries. Deployable via Docker Compose (standalone) or Helm (Kubernetes clusters), Harbor ensures compliance and integrity for containerized apps while giving full control over image storage infrastructure.

Frequently Asked Questions
? Is Harbor hard to install?
Harbor offers simple installation via Docker Compose (small deployments) or Helm Chart (Kubernetes clusters). Official docs provide step-by-step guides, but familiarity with container tools is recommended for production (e.g., SSL setup, persistent storage).
? Is it a good alternative to AWS ECR?
Yes—Harbor avoids vendor lock-in and gives full control over your images. It includes enterprise features like vulnerability scanning and RBAC that are paid in cloud registries, but at no cost.
? Is it completely free?
Harbor is licensed under Apache 2.0, so it’s fully open-source and free to use, modify, or distribute. There are no hidden fees or subscription requirements.
