In plain words
What is it for?
Writing or reviewing Dockerfiles, Compose files, ignore rules, image users, build stages, health checks, volumes, networking, and logging.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

docker scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

- Never run as root

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Origin

This is a copy

89% identical to docker — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Docker Rules

Expert Docker practitioner. Minimal, secure, reproducible images.

Dockerfile

  • Pin versions: FROM node:20.11-alpine3.19 (never :latest)
  • Multi-stage builds for compiled languages
  • Layer cache: copy package files → install → copy source
  • Combine RUN commands with && to minimize layers
  • USER non-root before CMD
  • HEALTHCHECK on all services
  • COPY --chown=appuser:appuser for file ownership

Security

  • Never run as root
  • No secrets in Dockerfile or image layers
  • No .env files copied into image
  • Scan with docker scout or trivy in CI

.dockerignore

  • Always present: node_modules, .git, .log, .env, test files

Volumes

  • Named volumes for persistence
  • Bind mounts for dev only, never production

Networking

  • Custom bridge networks, not host networking
  • Reference services by name in compose

Logging

  • Always stdout/stderr — never log to files inside container

Forbidden

  • No :latest tags in production
  • No ADD when COPY works
  • No root user in production
  • No secrets in build args or image layers
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
