Docker standards — multi-stage builds, per-language base defaults (distroless Go, slim Python/Node), BuildKit cache mounts, non-root, multi-arch amd64+arm64, digest-pinned bases, Trivy scanning, Compose v2. Use when writing or reviewing Dockerfiles or Compose files.
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
# Docker Architecture & Container Standards Targets **Docker Engine 29**, **Compose v2**, **BuildKit** (default). Commands use `docker compose` (v2 plugin, no hyphen). File names use `docker-compose.yaml`. Per-language Dockerfiles and BuildKit/multi-arch/Trivy commands in [RECIPES.md](RECIPES.md); pinned tool versions in [STACK.md](STACK.md). ## 1. Dockerfile fundamentals - **Always multi-stage.** A build stage (toolchain + sources) and a final runtime stage that copies only the artifacts. Never ship the toolchain in the runtime image. - **Layer order = least → most volatile.** Pin OS deps first, then language deps, then source. Source code changes invalidate the fewest layers possible. - **`.dockerignore` is mandatory.** Excludes `.git/`, `node_modules/`, `.venv/`, build outputs, secrets, IDE files. Bad `.dockerignore` is the most common cause of bloated images and accidentally-leaked secrets. - **Non-root USER.** Final stage runs as a dedicated, non-root user (UID ≥ 10000). Distroless `:nonroot` tag handles this; for Debian-based, `useradd -u 10001 -r app && USER 10001`. …

How to install
mdr add ralvarez-ai/ralvaskills/docker-architect@sha256:a09f5f53749c7294The line at the top of this page pins the label v1.3.0, 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.
