This repository is the source of truth for the official Node.js Docker images published on Docker Hub. It contains no application runtime code; it is a release-engineering and build-automation repo that owns three concerns: (1) template-based Dockerfile generation across Node.js major versions 22/24/26 and variants (Alpine 3.23/3.24, Debian bookworm/trixie, and slim flavors), (2) continuous detection of new Node.js releases, and (3) generation of the stackbrew manifest consumed by docker-library/official-images, which triggers the actual Docker Hub build. The generated Dockerfiles perform GPG-verified SHA-256 checksum validation of Node.js tarballs, multi-architecture dispatch (binary download where official musl/glibc builds exist, source compilation otherwise), OpenSSL header pruning to save ~34MB, apt/apk dependency minimization, and runtime smoke tests of node/npm/yarn. The core pipeline is fully automated: a GitHub Actions cron runs every 15 minutes, executing build-automation.mjs which queries nodejs.org/download/release/index.json, detects newer releases, and invokes update.sh. update.sh is the heart of the repo — a bash generator that expands three Dockerfile templates by injecting GPG release keys, architecture-to-binary switch cases, and per-major-version policy (Yarn v1 is stripped for Node >=26; rust/cargo toolchain is stripped for Node <26 since Temporal doesn't require it). When an update PR merges, official-pr.yml regenerates the stackbrew manifest via stackbrew.js and opens a PR against docker-library/official-images. A diff-aware test matrix (genMatrix.js) builds every affected Dockerfile in CI and asserts the resulting node/npm/yarn versions. Craftsmanship is strong: shell scripts are organized as a reusable utility library (functions.sh), linted with shfmt/ShellCheck and ESLint/Prettier/doctoc; GitHub Actions are pinned to commit SHAs; OpenSSF Scorecard supply-chain analysis runs; release GPG keys are synced automatically from nodejs/release-keys. The most transferable artifacts are update.sh (declarative template-to-Dockerfile generation), stackbrew.js (release-schedule-driven tag policy), genMatrix.js (diff-aware CI matrix generation), and docker-entrypoint.sh (the canonical runtime-command dispatch pattern with a documented ash/dash bug workaround). The repo is actively maintained — it tracks current Node.js 26, Alpine 3.24, and Debian 13 (trixie) — and is monolithic in structure but cohesive: a single-purpose infrastructure repo rather than a data/research project.
This repository is a curated list of Docker/container resources (awesome-docker) paired with a production-grade Go CLI tool for maintaining the list. The CLI provides commands for parsing the README, linting entries (alphabetical order, description capitalization, period, duplicates), checking external and GitHub links concurrently, scoring repository health via the GitHub API, generating markdown/JSON health reports, building a static website from the README, an interactive TUI browser, and pruning stale/archived entries from both the README and the health cache. The architecture is modular with clear separation of concerns: parser, linter, checker, scorer, cache, builder, pruner, and TUI packages. The code is well-tested, uses modern Go idioms (Cobra CLI, Bubbletea TUI, GitHub GraphQL API), and is backed by comprehensive CI/CD workflows. The project is actively maintained with frequent commits, dependabot updates, and automated health reports. While the primary value is the curated list, the tooling itself is a high-quality, reusable framework for managing any curated awesome list.
werf is a production-grade CLI tool for full-cycle CI/CD of containerized applications to Kubernetes. It provides a unified pipeline for building container images (via Docker or Buildah backends), managing Git-based reproducible configurations (giterminism), deploying Helm charts with advanced tracking and lifecycle management, and performing cleanup of container registry and host resources. The architecture is monolithic but modular, with clear interface abstractions for container backends, registry clients, stage storage, and parallel execution. The codebase demonstrates high craftsmanship in areas like composable path matching, deterministic slug generation, and distributed locking, though it carries some duplication between legacy and modern deploy engines and a few forked dependencies. The repository is actively maintained with frequent releases and extensive test coverage across unit, integration, and e2e suites.
Portainer Community Edition is a full-stack container management platform providing a unified web UI and REST API for Docker, Docker Swarm, Podman, Kubernetes, Azure Container Instances, and edge computing environments. The backend is written in Go, using BoltDB for storage, gorilla/mux for routing, and includes proxy layers for Docker/Kubernetes/Azure APIs, Helm chart management, GitOps workflows, LDAP/OAuth authentication, RBAC, and backup/restore functionality. The frontend is a hybrid of legacy AngularJS (1.8) and modern React with TypeScript, using React Query, Zustand, Formik, Yup, and a custom UI component library with Storybook. Key entry points are the Go main command (api/cmd/portainer/main.go) and the webpack-compiled React/AngularJS app (app/app.js). The system manages endpoints, stacks, services, containers, volumes, networks, images, registries, edge devices, user teams, and access controls through a layered architecture of HTTP handlers, data services, and middleware. External dependencies include Docker SDK, Kubernetes client libraries, Helm SDK, and various third-party registries.
Samarium is a modular, all-in-one business management system (ERP/CMS) built with Laravel 11 and Livewire 3. It provides a comprehensive admin dashboard for small to medium businesses, covering sales invoicing, purchase orders, expense tracking, inventory management, accounting (double-entry ledger, trial balance, income statement), customer/vendor relationship management, and a full content management system (webpages, posts, galleries, navigation menus, themes). It also includes e-commerce capabilities (product catalog, shopping cart, online orders), appointment booking, team management, calendar with Nepali date support, and additional modules like vacancies, testimonials, newsletters, and document/URL link management. The system is configurable via a module toggle in config/app.php and supports both a dashboard interface and a public-facing website. The architecture follows a standard Laravel MVC pattern with Livewire components handling all interactive UI. Each business domain has its own set of Livewire components (e.g., SaleInvoiceEditor, ProductDisplay) that use a shared ModesTrait for state management. A service layer provides pagination and CRUD logic, though many service methods are incomplete. The frontend uses Bootstrap 4, Font Awesome, and Chart.js for reporting. The system is Dockerized for easy deployment and includes seeders for demo data. While the codebase is functional and covers a wide feature set, it exhibits several quality issues: mixed namespaces (some models under App\, others under App\Models\), hardcoded values (VAT 13%, Nepali month arrays), incomplete features (many TODO comments, empty service methods), and code duplication (multiple similar Livewire components for editing fields). The Nepali calendar support is a distinctive feature but requires manual maintenance of hardcoded date ranges. Overall, Samarium is a solid, feature-rich ERP for its target audience but would benefit from refactoring and stricter coding standards.
This repository provides a deprecated Docker image for running Starlette applications with Uvicorn managed by Gunicorn. The image includes auto-tuning of worker processes based on CPU cores. However, the project is explicitly deprecated in favor of using Uvicorn with the `--workers` option directly, as the need for Gunicorn as a process manager has been eliminated by recent Uvicorn features. The repository contains Dockerfiles for Python 3.10 and 3.11 (slim and non-slim) that build upon the `tiangolo/uvicorn-gunicorn` base image, and installs Starlette. It includes a minimal example application and tests to verify the image behavior.
