Securing Container Registry with Harbor

Overview

Harbor is an open-source container registry that provides security features including vulnerability scanning (integrated Trivy), image signing (Notary/Cosign), RBAC, content trust policies, replication, and audit logging. Securing Harbor involves configuring these features to enforce image provenance, prevent vulnerable image deployment, and maintain registry access control.

When to Use

• When deploying or configuring securing container registry with harbor capabilities in your environment
• When establishing security controls aligned to compliance requirements
• When building or improving security architecture for this domain
• When conducting security assessments that require this implementation

Prerequisites

• Harbor 2.10+ installed (Helm or Docker Compose)
• TLS certificates for HTTPS
• Trivy scanner integration
• OIDC/LDAP for authentication
• Kubernetes cluster (for deployment target)

Workflow

Step 1: Install Harbor with Security Configuration

# harbor-values.yaml for Helm deployment
expose:
  type: ingress
  tls:
    enabled: true
    certSource: secret
    secret:
      secretName: harbor-t…
