DockMon

A comprehensive Docker container monitoring and management platform with real-time monitoring, intelligent auto-restart, multi-channel alerting, and complete event logging.

Key Features

• Multi-Host Monitoring - Monitor containers across unlimited Docker hosts (local and remote)
• Agent-Based Remote Monitoring - Lightweight Go agent for secure remote Docker monitoring without exposing Docker ports. Runs as a container or systemd service
• Real-Time Dashboard - Drag-and-drop customizable widgets with WebSocket updates
• Real-Time Statistics - Live CPU, memory, network metrics
• Historical Stats - Optional time-series persistence for CPU, memory, and network metrics with retention up to 90 days. Browse historical charts in host and container modals via a time-range selector (5m / 1h / 24h / 7d / 30d / 60d / 90d). Disabled by default (privacy); opt in from Settings → System
• Real-Time Container Logs - View logs from multiple containers simultaneously with live updates
• Event Viewer - Comprehensive audit trail with filtering, search, and real-time updates
• Intelligent Auto-Restart - Per-container auto-restart with configurable retry logic
• Advanced Alerting - Discord, Slack, Telegram, Pushover, Gotify, SMTP with customizable templates
• Container Tagging - Automatic tag derivation from Docker labels with user-defined tags
• Bulk Operations - Start, stop, restart multiple containers simultaneously with progress tracking
• Stack Management - Create, edit, and deploy Docker Compose stacks to local and remote hosts. Import existing stacks from running containers or host filesystems, with real-time deployment progress and layer-by-layer image pull tracking
• Automatic Updates - Detect and execute container image updates on schedule
• HTTP/HTTPS Health Checks - Custom endpoint monitoring with auto-restart on failure
• Blackout Windows - Schedule maintenance periods to suppress alerts
• Multi-User Support - Group-based RBAC with custom groups, granular capabilities, and user management
• OIDC/SSO Integration - Single sign-on with any OIDC provider (Authentik, Keycloak, Okta, Entra ID, Auth0), automatic group sync, and optional user approval workflow
• API Keys - Programmatic access with group-based permissions, optional IP restrictions, and expiration
• Secure by Design - Session-based auth, rate limiting, mTLS for remote hosts, Alpine Linux base

Technology Stack

Backend

• Python 3.13 with FastAPI and async/await
• Alpine Linux 3.x container base (reduced attack surface)
• OpenSSL 3.x for modern cryptography
• SQLAlchemy 2.0 with Alembic migrations
• Go 1.23 stats service for real-time metrics streaming

Frontend

• React 18.3 with TypeScript (strict mode, zero any)
• Vite for fast development builds
• TanStack Table for data tables
• React Grid Layout for dashboard customization
• Tailwind CSS for styling

Infrastructure

• Multi-stage Docker build - Go stats + React frontend + Python backend
• Supervisor for process management
• Nginx reverse proxy with SSL/TLS
• WebSocket for real-time updates
• Health checks for all services

Upgrading from v1 to v2

Breaking Changes

• Alert Rules: Old alert rules must be recreated using the new alert system
• mTLS Certificates: Regenerate certificates due to Alpine's stricter OpenSSL 3.x requirements
• Database Schema: Automatic one-time migration from v1.1.3 to v2.0.0

Data Preserved

• ✅ Hosts and their configurations
• ✅ Containers and container history
• ✅ Event logs and audit trail
• ✅ User accounts and preferences

Post-Upgrade Steps

1. Regenerate mTLS certificates for remote hosts (see mTLS Setup Guide)
2. Recreate alert rules using the new alert system
3. Verify host connections after upgrade

See the Migration Guide for detailed instructions.
