implementing-container-image-minimal-base-with-distroless

What problem does it solve?

This Skill helps you reduce container attack surface by moving from traditional OS-based base images to Google distroless images that remove shells, package managers, and unnecessary utilities.

Core Features & Use Cases

• Multi-stage build guidance: Provides concrete Dockerfile patterns for Go, Java, Python, and Node.js to ensure only runtime artifacts land in the distroless stage.
• Security posture comparison: Includes a script to scan images with Trivy and compare vulnerability and size reductions between a standard base and a distroless equivalent.
• Distroless property validation: Checks whether an image actually behaves like distroless (e.g., no shell and no detected package manager), helping you verify hardening results.

Quick Start

Run the distroless migration assessment by scanning and comparing your current base image against a chosen distroless runtime image, then review the generated report in JSON.
