This repository is a comprehensive Chinese-language Docker tutorial and technical book ('Docker 从入门到实践') rather than a traditional software service. The dominant content is structured Markdown chapters covering Docker introduction, installation, images, containers, registries, Dockerfile best practices, Compose, Kubernetes, cloud integrations, security, observability, and practical case studies. It also contains validated example code such as Dockerfiles, Compose files, and Kubernetes manifests, plus a custom toolchain for building static HTML and PDF output. The repository operates as a documentation publishing pipeline. Markdown sources are consumed by npm scripts and Python tools: prepare_pdf_sources.py inlines images as data URIs for PDF generation; build_html_reader.py creates a single-file offline HTML reader with Mermaid and dark-mode support; verify_artifacts.py checks generated artifacts and produces SHA256 manifests. CI workflows on GitHub Pages build and deploy the site, run link checks, validate examples with native tools such as kubeconform and actionlint, and enforce CJK typography rules. Architecturally, this is a collection of small, mostly standalone Python and Node scripts plus CI workflow orchestration; there is no long-running backend or service. Key entry points are package.json scripts and the tools/ and tests/ directories. The data flow is document transformation: Markdown to HTML and PDF, with example validation performed during CI. External dependencies include mdPress, mermaid-cli, pandoc, and container runtime tooling for validating the examples. Maintenance is active and changelog-driven, with frequent updates tracking Docker and Kubernetes versions. Some mirror lists and example image tags inevitably become stale as the ecosystem moves, but the CI and test layers keep the content and build pipeline in good shape. The most reusable value lies in the documentation tooling and validation patterns, not in the tutorial prose itself.
