NORA

The artifact registry that grows with you. Starts with docker run, scales to enterprise.

docker run -d -p 4000:4000 -v nora-data:/data ghcr.io/getnora-io/nora:latest

Open http://localhost:4000/ui/ — your registry is ready.

Why NORA

• Zero-config — single 32 MB binary, no database, no dependencies. docker run and it works.
• Production-tested — Docker (+ Helm OCI), Maven, npm, PyPI, Cargo, Go, Raw. Used in real CI/CD with ArgoCD, Buildx cache, and air-gapped environments.
• Secure by default — OpenSSF Scorecard, signed releases, SBOM, fuzz testing, 200+ unit tests.

32 MB binary | < 100 MB RAM | 3s startup | 7 registries

Used in production at DevIT Academy since January 2026 for Docker images, Maven artifacts, and npm packages.

Supported Registries

Registry	Mount Point	Upstream Proxy	Auth
Docker Registry v2	/v2/	Docker Hub, GHCR, any OCI, Helm OCI	✓

Authentication

NORA supports Basic Auth (htpasswd) and revocable API tokens with RBAC.

# Create htpasswd file
htpasswd -cbB users.htpasswd admin yourpassword

# Start with auth enabled
docker run -d -p 4000:4000 \
  -v nora-data:/data \
  -v ./users.htpasswd:/data/users.htpasswd \
  -e NORA_AUTH_ENABLED=true \
  ghcr.io/getnora-io/nora:latest

Role	Pull/Read	Push/Write	Delete/Admin
read	Yes	No	No
write	Yes	Yes	No
admin	Yes	Yes	Yes

See Authentication guide for token management, Docker login, and CI/CD integration.

registry.example.com {
    reverse_proxy localhost:4000
}

See TLS / HTTPS guide for Nginx, Traefik, and custom CA setup.

Roadmap

• Mirror CLI — offline sync for air-gapped environments
• OIDC / Workload Identity — zero-secret auth for GitHub Actions, GitLab CI
• Online Garbage Collection — non-blocking cleanup without registry downtime
• Retention Policies — declarative rules: keep last N tags, delete older than X days
• Image Signing — cosign verification and policy enforcement

See CHANGELOG.md for release history.

Security & Trust

• Signed releases — every release is signed with cosign
• SBOM — SPDX + CycloneDX in every release
• Fuzz testing — cargo-fuzz + ClusterFuzzLite
• Blob verification — SHA256 digest validation on every upload
• Non-root containers — all images run as non-root
• Security headers — CSP, X-Frame-Options, nosniff

See SECURITY.md for vulnerability reporting.
