docker-templates skillA
docker-templates is agent-read markdown (skill) from komluk/scaffolding: 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)..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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@git:20260520.3aa374bmdr add komluk/scaffolding/docker-templates@sha256:e56ec053f1dbfb66Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
