Dockge is a self-hosted web application for managing Docker Compose stacks. It provides a graphical interface to create, edit, deploy, and manage stacks composed of multiple containers. The application supports managing multiple Docker hosts (agents) from a single interface, enabling centralized control of distributed Docker environments. Key features include a web-based terminal for container access, real-time updates via Socket.io, stack lifecycle management, and extensive customization through settings and environment variables. The architecture consists of a Node.js/Express backend with Socket.io for real-time communication and a Vue.js 3 frontend built with Vite. The backend handles Docker interactions, database operations (using SQLite or MySQL for metadata), and agent management, while the frontend delivers a responsive UI with internationalization support. Data flows involve the frontend sending user actions to the backend via Socket.io, which then interacts with the Docker daemon (local or via agents) and persists stack definitions as compose.yaml files on disk. The system emphasizes a file-based approach for stack definitions, ensuring portability and transparency. Dockge demonstrates strong engineering practices through its modular design, including isolated components for settings caching, terminal management, rate limiting, and an extensible agent system. These components exhibit low coupling and high reusability, adhering to principles of separation of concerns and maintainability. The application also incorporates modern development practices such as multi-stage Docker builds, automated CI/CD, and comprehensive test coverage (though not detailed in the provided summaries, the presence of CI workflows suggests testing efforts).
1Panel is a production-grade, open-source Linux server management panel built on a distributed core-agent architecture. The system provides a comprehensive web-based GUI (Vue 3 frontend) and a REST API (Go/Gin) that orchestrates an agent running on each managed host. It covers the full server lifecycle: website management (Nginx/OpenResty with custom config parser), database administration (MySQL, PostgreSQL, MongoDB, Redis), Docker container orchestration, firewall management (abstraction over iptables, nftables, firewalld, UFW), system monitoring, backup/restore to multiple cloud storage providers, cron jobs, SSL certificate automation via ACME, and terminal access (local, SSH, container) with AI-assisted command generation. The architecture splits control plane (core) and execution plane (agent) communicating over Unix sockets or HTTPS, supporting multi-node environments. Notable engineering highlights include a reusable task framework with retry/rollback, a firewall lifecycle abstraction with rule identity hashing, a custom Nginx config lexer/parser, and an enterprise extension system via Go build tags and frontend dynamic imports. The codebase is actively maintained with frequent commits and a large open-source community (37k+ stars). However, there is significant code duplication between core and agent packages, and some hardcoded paths and legacy migration logic add complexity.
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.
