Vulnerability Scanning with Trivy, Clair, and Grype

🚀 One command to run all three vulnerability scanners using Docker - no local installation required!

Scanners-TrivyClairGrype is a comprehensive, zero-installation vulnerability scanning solution that integrates three powerful security scanners (Trivy, Clair, and Grype) into a single command.

Simply run .\run_all.bat on Windows or ./run_all.sh on Mac/Linux to automatically scan your codebase, Docker images, or directories for vulnerabilities, secrets, and misconfigurations using Docker containers - no local installation required.

The tool generates a combined HTML report with findings from all three scanners, making it perfect for developers, DevOps teams, and security professionals who want enterprise-grade vulnerability scanning without the complexity of setting up multiple tools individually.

🎯 Quick Start - Single Command

Windows

.\run_all.bat

Mac/Linux

./run_all.sh

Or directly (from within your codebase directory)

python scan_docker.py .

That's it! The script will automatically:

• ✅ Pull Docker images for all scanners
• ✅ Scan your codebase with Trivy, Grype, and Clair
• ✅ Generate a combined HTML report
• ✅ Open results in your browser
• ✅ Use descriptive container names for easy tracking

🏷️ Container Names

All containers now have descriptive, consistent names:

Scanner Containers (Temporary)

• trivy-scanner-TIMESTAMP - Trivy vulnerability scanner
• grype-scanner-TIMESTAMP - Grype vulnerability scanner

Clair Services (Persistent)

• clair-postgres-db - PostgreSQL database for Clair
• clair-vulnerability-scanner - Main Clair scanner service
• clair-control-tool - Clair control utility

Easy management:

# See what's running
docker ps

# View logs
docker logs clair-vulnerability-scanner

# Stop specific containers
docker stop trivy-scanner-20250625_070015

🔍 What Gets Scanned

✨ Comprehensive Coverage with Trivy + Grype

• 📁 Source code (vulnerabilities in dependencies)
• 🔒 Secrets (API keys, passwords hardcoded in code) - Trivy only
• 📦 Package managers (npm, pip, maven, gradle, composer, etc.)
• 📋 Configuration files (Dockerfile, Kubernetes YAML, Terraform) - Trivy only
• 🐳 Container images (OS and application vulnerabilities)
• 📊 Software Bill of Materials (SBOM) - Trivy only

🎯 Scanner Comparison

Feature	Trivy	Grype	Clair
Dependencies	✅	✅	✅
Secrets	✅	❌	❌
Configs	✅	❌	❌
Git Repos	✅	❌	❌
Containers	✅	✅	✅
Speed	Fast	Very Fast	Consistent
Setup	Easy	Easy	Optional

💡 Recommendation: Trivy + Grype provide excellent coverage for most security needs. Clair is optional for specialized container analysis.

📋 Requirements

• Docker (only requirement!)
• Python 3.6+ (usually pre-installed)

Install Docker

• Windows/Mac: Docker Desktop
• Linux: curl -fsSL https://get.docker.com | sh

🎯 Usage Examples

# Scan current directory (your project)
.\run_all.bat

# Scan specific directory
.\run_all.bat C:\path\to\project
./run_all.sh /path/to/project

# Scan Docker image
.\run_all.bat nginx:latest
./run_all.sh python:3.9

# Scan Git repository (real examples)
.\run_all.bat https://github.com/your-username/your-repo

📊 What You Get

Automated Report Generation

• JSON files for each scanner in results/ directory
• Combined HTML report with all findings
• Severity-based filtering (Critical, High, Medium, Low)
• Package and vulnerability details
• Fix recommendations when available

Report Structure

results/
├── trivy_results_TIMESTAMP.json
├── grype_results_TIMESTAMP.json
├── clair_results_TIMESTAMP.json (when available)
└── combined_report_TIMESTAMP.html  ← Opens automatically

🧪 Test with Mock Data

Want to see how the reports look with vulnerabilities? Run the test script:

python test_with_mock_data.py

This generates realistic vulnerability data for all three scanners so you can see the beautiful table formatting and severity color coding in action!

🚀 Alternative: Just Use Trivy (Easiest)

If you want the simplest solution, just install Trivy alone - it can do 90% of what you need:

Windows

# Using Chocolatey
choco install trivy

# Or download directly
$version = "0.52.2"
Invoke-WebRequest -Uri "https://github.com/aquasecurity/trivy/releases/download/v$version/trivy_$($version)_Windows-64bit.zip" -OutFile "trivy.zip"
Expand-Archive trivy.zip -DestinationPath "C:\trivy"
# Add C:\trivy to PATH

Mac

brew install trivy

Linux

curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh -s -- -b /usr/local/bin

Scan Everything with Just Trivy

# Scan your codebase for vulnerabilities and secrets
trivy fs .

# Scan container image
trivy image nginx:latest

# Scan git repository
trivy repo https://github.com/user/repo

# Scan for secrets only
trivy fs --scanners secret .

# Scan configuration files
trivy config .

# Docker version (no installation)
docker run --rm -v $(pwd):/workspace aquasec/trivy fs /workspace

🔧 Advanced Usage

Individual Scanner Commands (Docker)

Trivy:

# Scan filesystem/codebase
docker run --rm --name trivy-scan -v $(pwd):/workspace aquasec/trivy fs /workspace

# Scan for secrets in code
docker run --rm --name trivy-secrets -v $(pwd):/workspace aquasec/trivy fs --scanners secret /workspace

# Scan container image
docker run --rm --name trivy-image aquasec/trivy image nginx:latest

# Scan git repository
docker run --rm --name trivy-repo aquasec/trivy repo https://github.com/user/repo

Grype:

# Scan directory
docker run --rm --name grype-scan -v $(pwd):/workspace anchore/grype dir:/workspace

# Scan container image
docker run --rm --name grype-image anchore/grype nginx:latest

Clair:

# Start Clair services
docker-compose up -d

# Check status
curl http://localhost:6060/health

# Stop services
docker-compose down

🛠️ Local Installation (Alternative)

If you prefer to install scanners locally instead of using Docker:

Windows (PowerShell)

# Automated installer
.\install_scanners.ps1

# Or manual
choco install trivy
# Download Grype from GitHub releases

macOS

# Homebrew
brew install trivy
brew tap anchore/grype && brew install grype

Linux

# Install scripts
curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh
curl -sSfL https://raw.githubusercontent.com/anchore/grype/main/install.sh | sh

Then use the local scanner script:

python scan_all.py .
