containers-orchestration from d-padmanabhan/agent-engineering-handbook is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Docker and container best practices for production images, multi-stage builds, cache reuse, Docker Compose, health checks, scanning, publishing, and signing. Use when working with Dockerfiles, Containerfiles, Compose files, .dockerignore, image optimization, container security, docker push, Cosign, or Notation.
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
# Containers & Orchestration ## Guiding Principles 1. **Security First**: Non-root users, minimal base images, vulnerability scanning 2. **Efficiency**: Multi-stage builds, layer optimization, build cache 3. **Reproducibility**: Pin versions, explicit dependencies, deterministic builds 4. **Observability**: Health checks, proper logging, metrics endpoints ## Quick Reference | Aspect | Standard | |--------|----------| | **Base Images** | Official image; pin the immutable digest for production | | **Multi-Stage** | Required for compiled languages (Go, Rust, C++) | | **User** | Run as non-root (use `USER node` or create user) | | **Health Checks** | Include a meaningful `HEALTHCHECK` when the runtime exposes one | | **Scanning** | Registry-native scanning gates (JFrog Xray / AWS ECR enhanced scanning) | | **Signing** | Sign images with Sigstore/Cosign or Notation | ## Dockerfile Best Practices ### Use Official, Minimal Base Images ```dockerfile # ✅ GOOD - Official, minimal, secure FROM python:3.14-slim FROM node:20-alpine # ⭐ EXCELLENT - Distroless for production FROM gcr.io/distroless/python3-debian12 FROM gcr.io/distroless/nodejs20-debian12 …

How to install
mdr add d-padmanabhan/agent-engineering-handbook/containers-orchestration@sha256:12d6413a5397472aThe line at the top of this page pins the label git:20260819.d23bb73, 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.
