# Docker For A Small Business — Generate The Compose File You Actually Need Pick the services your small-business stack runs. Get a best-practice Dockerfile (multi-stage, non-root, health-checked) and a docker-compose.yml with volumes, networks, Traefik auto-HTTPS, and the env plumbing you'd forget. Author: J.A. Watte Published: April 20, 2026 Source: https://jwatte.com/blog/blog-tool-docker-gen/ --- **TL;DR.** Generators save hours of reference-hunting and make the default pattern auditable. The output is a strong 80% starting scaffold — review + tune the remaining 20% to your specifics before committing. The **[Docker Gen](/tools/docker-gen/)** is the audit you reach for when you already suspect a problem in this dimension and need a fast, copy-paste-able fix list. It reuses the same chrome as every other jwatte.com tool — deep-links from the mega analyzers, AI-prompt export, CSV/PDF/HTML download — but the checks it runs are narrow and specific to the dimension described above. > Pick a workload (static site, Node API, WordPress, Ghost, Postgres, Redis, n8n, Ollama). Get a best-practice Dockerfile + docker-compose.yml with security defaults, health checks, volume paths, and a deploy-anywhere README. ## Why this dimension matters Generators shortcut the "blank-page" problem. A drop-in template (robots.txt, sitemap, Dockerfile, Kubernetes manifest, llms.txt, JSON-LD scaffold) saves hours of reference-hunting and makes the default pattern auditable. The shipped output is never production-ready without review, but it's always a stronger starting point than an empty editor. ## Common failure patterns - **Generated template copied verbatim without local tuning** — every generator ships sensible defaults, but every real site has constraints the generator can't know (custom domains, staging hosts, legacy paths that must stay indexed). Review each directive; delete what doesn't apply. - **Generated config committed without a comment explaining the source** — six months later nobody remembers why a particular directive is there. Annotate with a `# Generated from jwatte.com/tools// on YYYY-MM-DD` line. - **Treating the generator output as final rather than starter scaffold** — the emitted file is an 80% default. The 20% is where your site's specifics live, and that's where review time belongs. ## How to fix it at the source Run the generator, take the output as a starting scaffold, then review every directive against your actual site: delete any that don't apply, tune any that have site-specific values, and commit with a comment linking back to the generator. Re-generate every 6–12 months — specs evolve (robots.txt now includes AI bots, manifest.json gained fields, Dockerfile best practices shift) and the generator tracks current best practice. ## When to run the audit - After a major site change — redesign, CMS migration, DNS change, hosting platform swap. - Quarterly as part of routine technical hygiene; the checks are cheap to run repeatedly. - Before an investor / client review, a PCI scan, a SOC 2 audit, or an accessibility-compliance review. - When a downstream metric drops (rankings, conversion, AI citations) and you need to rule out this dimension as the cause. ## Reading the output Every finding is severity-classified. The playbook is the same across tools: - **Critical / red** — same-week fixes. These block the primary signal and cascade into downstream dimensions. - **Warning / amber** — same-month fixes. Drag the score, usually don't block. - **Info / blue** — context only. Often what a PR reviewer would flag but that doesn't block merge. - **Pass / green** — confirmation. Keep the control in place. Every audit also emits an "AI fix prompt" — paste into ChatGPT / Claude / Gemini for exact copy-paste code patches tied to your specific stack. ## Related tools in this family - **[Mega Analyzer](/tools/mega-analyzer/)** — run the orchestrator first — the generator is the fix, the orchestrator is the diagnosis. - **[ai.txt Generator](/tools/ai-txt-gen/)** — generates ai.txt + llms.txt scaffolds. - **[robots.txt Simulator](/tools/robots-txt-simulator/)** — verify the generator's robots.txt matches what each bot actually sees. - **[SEO Roadmap Generator](/tools/seo-roadmap-generator/)** — emits a 30/60/90 plan tied to audit findings. - **[Monoclone Gen.](/tools/monoclone-generator/)** — multi-locale page cloning from a template. ## Fact-check notes and sources - See the specific tool's footer for the canonical spec reference (Sitemaps.org, llmstxt.org, Docker reference, etc.). - Treat the output as a known-good starting point; review + adapt to your site before committing. *This post is informational and not a substitute for professional consulting.
