'This skill covers hardening container images by minimizing attack surface,.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Performing Container Image Hardening ## When to Use - When building production container images that need minimal attack surface - When compliance requires CIS Docker Benchmark adherence for container configurations - When reducing image size to minimize vulnerability exposure from unused packages - When implementing defense-in-depth for containerized workloads - When migrating from fat base images to distroless or minimal images **Do not use** for runtime container security monitoring (use Falco), for host-level Docker daemon hardening (use CIS Docker Benchmark host checks), or for container orchestration security (use Kubernetes security scanning). ## Prerequisites - Docker or BuildKit for multi-stage builds - Base image options: distroless, Alpine, slim, or scratch - Container scanning tool (Trivy) for validation - CIS Docker Benchmark reference ## Workflow ### Step 1: Use Multi-Stage Builds to Minimize Image Size ```dockerfile # Build stage with all dependencies FROM python:3.12-bookworm AS builder WORKDIR /build COPY requirements.txt . RUN pip install --no-cache-dir --prefix=/install -r requirements.txt COPY src/ ./src/ RUN python -m compileall src/ …

How to install
mdr add adriannoes/awesome-agentic-ai/performing-container-image-hardening@sha256:4bd116ec9bf56b56The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
