diffused-cli 0.2.0

A vulnerability scan diffing command-line tool for container images and SBOMs

Diffused CLI

Command-line interface for the Diffused vulnerability scanning and diffing library. This tool provides an easy-to-use interface for comparing container images and SBOMs (Software Bill of Materials) to track security improvements and regressions.

Features

• 🔍 Container Image Comparison: Compare vulnerabilities between different container image versions
• 📊 SBOM Diffing: Direct comparison of SPDX-JSON formatted SBOMs (Trivy only)
• 📄 Multiple Output Formats: Support for both rich text and JSON output
• 🎨 Rich Terminal Output: Beautiful, colored output for better readability

Installation

Prerequisites

1. Install the scanner:
   1. Trivy: Follow the official Trivy installation guide
   2. RHACS: Follow the official roxctl installation guide
2. Python Environment: Ensure Python 3.9+ is installed

From Source

# Install the library
pip install -e ./diffused

# Install the CLI
pip install -e ./diffusedcli

From PyPI

pip install diffusedcli

Usage

Compare Container Images

# Basic vulnerability diff between two container images
diffused image-diff -p ubuntu:20.04 -n ubuntu:22.04

# Use ACS scanner
diffused --scanner acs image-diff -p nginx:1.20 -n nginx:1.21

# Save output to JSON file
diffused image-diff -p app:v1.0 -n app:v2.0 --output json --file report.json

Compare SBOMs

# Compare two SBOM files
diffused sbom-diff -p previous.json -n current.json

# Get detailed vulnerability information
diffused sbom-diff -p old-sbom.json -n new-sbom.json --all-info

# Export to file with rich formatting
diffused sbom-diff -p v1-sbom.json -n v2-sbom.json --file vulnerability-report.txt
