## Quick Start

### Docker (Recommended)

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

### From Source

```bash
cargo install nora-registry
nora
```

Open http://localhost:4000/ui/

## Usage

### Docker Images

```bash
# Tag and push
docker tag myapp:latest localhost:4000/myapp:latest
docker push localhost:4000/myapp:latest

# Pull
docker pull localhost:4000/myapp:latest
```

### Maven

```xml
<!-- settings.xml -->
<server>
  <id>nora</id>
  <url>http://localhost:4000/maven2/</url>
</server>
```

### npm

```bash
npm config set registry http://localhost:4000/npm/
npm publish
```

## Authentication

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

### Quick Setup

```bash
# 1. Create htpasswd file with bcrypt
htpasswd -cbB users.htpasswd admin yourpassword
# Add more users:
htpasswd -bB users.htpasswd ci-user ci-secret

# 2. Start NORA 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

# 3. Verify
curl -u admin:yourpassword http://localhost:4000/v2/_catalog
```

### API Tokens (RBAC)

Tokens support three roles: `read`, `write`, `admin`.

```bash
# Create a write token (30 days TTL)
curl -s -X POST http://localhost:4000/api/tokens \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"yourpassword","role":"write","ttl_days":90,"description":"CI/CD"}'

# Use token with Docker
docker login localhost:4000 -u token -p nra_<token>

# Use token with curl
curl -H "Authorization: Bearer nra_<token>" http://localhost:4000/v2/_catalog

# List tokens
curl -s -X POST http://localhost:4000/api/tokens/list \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"yourpassword"}'

# Revoke token by hash prefix
curl -s -X POST http://localhost:4000/api/tokens/revoke \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"yourpassword","hash_prefix":"<first 16 chars>"}'
```

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

## CLI Commands

```bash
nora              # Start server
nora serve        # Start server (explicit)
nora backup -o backup.tar.gz
nora restore -i backup.tar.gz
nora migrate --from local --to s3
```

## TLS / HTTPS

NORA serves plain HTTP by design. **TLS is intentionally not built into the binary** — this is a deliberate architectural decision:

- **Single responsibility**: NORA manages artifacts, not certificates. Embedding TLS means bundling Let's Encrypt clients, certificate renewal logic, ACME challenges, and custom CA support — all of which already exist in battle-tested tools.
- **Operational simplicity**: One place for certificates (reverse proxy), not scattered across every service. When a cert expires, you fix it in one config — not in NORA, Grafana, GitLab, and every other service separately.
- **Industry standard**: Docker Hub, GitHub Container Registry, AWS ECR, Harbor, Nexus — none of them terminate TLS in the registry process. A reverse proxy in front is the universal pattern.
- **Zero-config internal use**: On trusted networks (lab, CI/CD), NORA works out of the box without generating self-signed certs or managing keystores.

### Production (recommended): reverse proxy with auto-TLS

```
Client → Caddy/Nginx (HTTPS, port 443) → NORA (HTTP, port 4000)
```

Caddy example:

```
registry.example.com {
    reverse_proxy localhost:4000
}
```

Nginx example:

```nginx
server {
    listen 443 ssl;
    server_name registry.example.com;
    ssl_certificate     /etc/letsencrypt/live/registry.example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/registry.example.com/privkey.pem;
    client_max_body_size 0;  # unlimited for large image pushes
    location / {
        proxy_pass http://127.0.0.1:4000;
        proxy_set_header Host $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}
```

### Internal / Lab: insecure registry

If you run NORA without TLS (e.g., on a private network), configure Docker to trust it:

```json
// /etc/docker/daemon.json
{
  "insecure-registries": ["192.168.1.100:4000"]
}
```

Then restart Docker:

```bash
sudo systemctl restart docker
```

> **Note:** `insecure-registries` disables TLS verification for that host. Use only on trusted networks.

## FSTEC-Certified OS Builds

NORA provides dedicated Dockerfiles for Russian FSTEC-certified operating systems:

- `Dockerfile.astra` — Astra Linux SE (for government and defense sector)
- `Dockerfile.redos` — RED OS (for enterprise and public sector)

Both use `scratch` base with statically-linked binary for minimal attack surface. Comments in each file show how to switch to official distro base images if required by your security policy.

These builds are published as `-astra` and `-redos` tagged images in GitHub Releases.

## Performance

| Metric | NORA | Nexus | JFrog |
|--------|------|-------|-------|
| Startup | < 3s | 30-60s | 30-60s |
| Memory | < 100 MB | 2-4 GB | 2-4 GB |
| Image Size | 32 MB | 600+ MB | 1+ GB |
