docker-templates SKILL.md skillA
docker-templates from komluk/scaffolding is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add komluk/scaffolding/docker-templates@git:20260520.3aa374bPins git:20260520.3aa374b in mdr.lock. Pin the fingerprint instead.

Docker multi-stage build templates, image security, and docker-compose patterns. TRIGGER when: writing a Dockerfile, composing services, or hardening a container image. SKIP: CI pipeline definitions (use github-actions-template); runtime monitoring (use monitoring-observability).
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
## Multi-stage Build Pattern
```dockerfile
# Build stage
FROM node:20-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production=false
COPY . .
RUN npm run build
# Production stage
FROM node:20-alpine AS production
WORKDIR /app
# Security: Non-root user
RUN addgroup -g 1001 -S nodejs && \
adduser -S nextjs -u 1001
# Copy only production artifacts
COPY --from=builder --chown=nextjs:nodejs /app/dist ./dist
COPY --from=builder --chown=nextjs:nodejs /app/node_modules ./node_modules
COPY --from=builder --chown=nextjs:nodejs /app/package.json ./
USER nextjs
EXPOSE 3000
# Health check
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
CMD wget --no-verbose --tries=1 --spider http://localhost:3000/health || exit 1
CMD ["node", "dist/server.js"]
```
## Docker Security Best Practices
| Practice | Implementation |
|----------|----------------|
| Non-root user | `USER nodejs` after setup |
| Minimal base image | Use `-alpine` variants |
| No secrets in image | Use runtime env vars |
| Pin versions | `FROM node:20.10.0-alpine` |
| .dockerignore | Exclude node_modules, .git, .env |
…Read the whole file at its exact version.
How to install
mdr add komluk/scaffolding/docker-templates@sha256:e56ec053f1dbfb66The line at the top of this page pins the label git:20260520.3aa374b, 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.
