```

### Examples

```bash
# Scan with all scanners (default)
dockerscan myapp:latest

# Only run specific scanners
dockerscan --scanners secrets,supplychain redis:7

# Save reports to specific directory
dockerscan --output /var/reports postgres:14

# Only show critical issues
dockerscan --only-critical production-app:v1.0

# Verbose mode
dockerscan --verbose ubuntu:22.04

# Scan private registry images (see Authentication section below)
dockerscan ghcr.io/myorg/private-app:v1.0
```

### 🔐 Private Registry Authentication

DockerScan supports three methods for authenticating with private registries:

#### Method 1: Docker Config File (Recommended for Local Use)

The most convenient method - uses your existing Docker credentials:

```bash
# First, authenticate with your registry using Docker
docker login ghcr.io
# Username: your-username
# Password: ghp_your-token-here

# Now DockerScan can use these credentials automatically
dockerscan ghcr.io/myorg/private-app:latest
```

DockerScan automatically reads credentials from `~/.docker/config.json`. This works with all registries you've logged into with `docker login`.

#### Method 2: Environment Variables (Recommended for CI/CD)

Best for automated environments and CI/CD pipelines:

```bash
# Set environment variables
export DOCKER_USERNAME=myusername
export DOCKER_PASSWORD=mytoken

# Scan private image
dockerscan ghcr.io/myorg/private-app:latest

# Or use alternative variable names
export REGISTRY_USERNAME=myusername
export REGISTRY_PASSWORD=mytoken
dockerscan myregistry.example.com/app:v1.0
```

**CI/CD Example (GitHub Actions):**
```yaml
- name: Scan private image
  env:
    DOCKER_USERNAME: ${{ secrets.REGISTRY_USERNAME }}
    DOCKER_PASSWORD: ${{ secrets.REGISTRY_TOKEN }}
  run: dockerscan ghcr.io/${{ github.repository }}:${{ github.sha }}
```

#### Method 3: Command-Line Flags (Not Recommended)

For quick testing only (credentials visible in process list):

```bash
dockerscan --registry-user myuser --registry-password mytoken ghcr.io/myorg/app:v1
```

**Security Warning:** This method exposes credentials in your shell history and process list. Use environment variables or Docker config instead.

### Registry-Specific Examples

#### Docker Hub (Private Repositories)

```bash
# Using Docker config
docker login docker.io
dockerscan myusername/private-repo:latest

# Using environment variables
export DOCKER_USERNAME=myusername
export DOCKER_PASSWORD=dckr_pat_XXXXXXXXXXXXX
dockerscan myusername/private-repo:latest
```

#### GitHub Container Registry (GHCR)

```bash
# Using Docker config
echo $GITHUB_TOKEN | docker login ghcr.io -u USERNAME --password-stdin
dockerscan ghcr.io/myorg/myapp:v1.0

# Using environment variables
export DOCKER_USERNAME=myusername
export DOCKER_PASSWORD=ghp_XXXXXXXXXXXXXXXXXXXX
dockerscan ghcr.io/myorg/myapp:v1.0
```

#### AWS Elastic Container Registry (ECR)

```bash
# Get login credentials from AWS
aws ecr get-login-password --region us-east-1 | \
  docker login --username AWS --password-stdin \
  123456789012.dkr.ecr.us-east-1.amazonaws.com

# Scan ECR image
dockerscan 123456789012.dkr.ecr.us-east-1.amazonaws.com/myapp:latest

# Or use environment variables with ECR credentials
export DOCKER_USERNAME=AWS
export DOCKER_PASSWORD=$(aws ecr get-login-password --region us-east-1)
dockerscan 123456789012.dkr.ecr.us-east-1.amazonaws.com/myapp:latest
```

#### Google Container Registry (GCR) / Artifact Registry

```bash
# Authenticate with gcloud
gcloud auth configure-docker gcr.io

# Scan GCR image
dockerscan gcr.io/my-project/myapp:latest

# For Artifact Registry
gcloud auth configure-docker us-docker.pkg.dev
dockerscan us-docker.pkg.dev/my-project/my-repo/myapp:latest

# Or use service account JSON key
export DOCKER_USERNAME=_json_key
export DOCKER_PASSWORD="$(cat service-account-key.json)"
dockerscan gcr.io/my-project/myapp:latest
```

#### Azure Container Registry (ACR)

```bash
# Login with Azure CLI
az acr login --name myregistry

# Scan ACR image
dockerscan myregistry.azurecr.io/myapp:v1.0

# Or use service principal credentials
export DOCKER_USERNAME=<service-principal-id>
export DOCKER_PASSWORD=<service-principal-password>
dockerscan myregistry.azurecr.io/myapp:v1.0
```

#### GitLab Container Registry

```bash
# Using Docker config
docker login registry.gitlab.com
dockerscan registry.gitlab.com/mygroup/myproject/myapp:latest

# Using environment variables with deploy token
export DOCKER_USERNAME=gitlab+deploy-token-1
export DOCKER_PASSWORD=DEPLOY_TOKEN_HERE
dockerscan registry.gitlab.com/mygroup/myproject/myapp:latest
```

#### Self-Hosted/Private Registries

```bash
# Standard authentication
docker login myregistry.example.com:5000
dockerscan myregistry.example.com:5000/myapp:latest

# With environment variables
export DOCKER_USERNAME=admin
export DOCKER_PASSWORD=secret
dockerscan myregistry.example.com:5000/myapp:latest

# Insecure registries (not recommended for production)
# Add to Docker daemon config: /etc/docker/daemon.json
# {
#   "insecure-registries": ["myregistry.example.com:5000"]
# }
```

### Troubleshooting Authentication

#### Common Issues

**1. "authentication required" error**
```bash
# Make sure you're logged in
docker login <registry>

# Or set environment variables
export DOCKER_USERNAME=your-username
export DOCKER_PASSWORD=your-token
```

**2. "unauthorized: authentication failed" error**
- Verify your credentials are correct
- Check if your token has expired (especially for cloud providers)
- Ensure your account has pull permissions for the image

**3. AWS ECR "authorization token has expired"**
```bash
# ECR tokens expire after 12 hours - refresh them
aws ecr get-login-password --region us-east-1 | \
  docker login --username AWS --password-stdin \
  123456789012.dkr.ecr.us-east-1.amazonaws.com
```

**4. Rate limiting on Docker Hub**
- Authenticate to increase rate limits (200 pulls/6 hours for free accounts)
- Consider using a Docker Hub Pro account for higher limits

**5. Certificate errors with self-signed certificates**
- Add the CA certificate to your system trust store
- Or configure Docker to trust the registry (see Docker documentation)

### CVE Database & nvd2sqlite Tool

DockerScan uses a local SQLite database for CVE lookups. The database is **automatically updated daily** via GitHub Actions and hosted in the repository, so you always have access to the latest CVE data.

#### Database Features

- 🗄️ **Pre-built database** - Ready to use, no manual setup required
- 🔄 **Daily updates** - GitHub Action updates the database every day at 00:00 UTC
- 📅 **2.5 years of CVE data** - Covers CVEs from mid-2022 to present
- ⚡ **Fast lookups** - SQLite with optimized indexes
- 🌐 **Hosted on GitHub** - Downloaded automatically with `update-db` command

#### Updating the Database

```bash
# Download latest database from GitHub (recommended)
dockerscan update-db

# Install from local file (for air-gapped/offline environments)
dockerscan update-db --from-file /path/to/cve-db.sqlite
```

> **Note**: The first time you run `dockerscan`, it will prompt you to download the database. After that, you can update it periodically with `update-db`.

#### Building the Database Manually (nvd2sqlite)

For advanced users, you can build the CVE database from NVD directly:

```bash
# Build the tool
make build  # Builds both dockerscan and nvd2sqlite

# Download CVEs (last 2.5 years by default)
./bin/nvd2sqlite --output data/cve-db.sqlite --verbose

# With NVD API key (10x faster - 50 req/30sec vs 5 req/30sec)
NVD_API_KEY=your-key ./bin/nvd2sqlite --output data/cve-db.sqlite --verbose

# Custom date range
./bin/nvd2sqlite --output data/cve-db.sqlite \
  --start-date 2023-01-01 \
  --end-date 2024-12-31
```

**nvd2sqlite features:**
- ⚡ **4 parallel download workers** for faster downloads
- 🔄 **Automatic retry with exponential backoff** for rate limiting (HTTP 429)
- 📦 **Downloads to temp directory**, then processes sequentially
- 🗄️ **SQLite output** with indexed tables for fast lookups

---

### Extensibility

Adding a new scanner is simple:

```go
package myscan

import (
    "context"
    "github.com/cr0hn/dockerscan/v2/internal/models"
    "github.com/cr0hn/dockerscan/v2/internal/scanner"
)

type MyScanner struct {
    scanner.BaseScanner
}

func NewMyScanner() *MyScanner {
    return &MyScanner{
        BaseScanner: scanner.NewBaseScanner(
            "my-scanner",
            "Description of my scanner",
            true, // enabled
        ),
    }
}

func (s *MyScanner) Scan(ctx context.Context, target models.ScanTarget) ([]models.Finding, error) {
    var findings []models.Finding

    // Your scanning logic here...

    return findings, nil
}

// Register in main.go:
// registry.Register(myscan.NewMyScanner())
```
