DocMon is a free and open source app for developers and IT professionals which provides modern Docker container monitoring with auto-restart and alerts. You can see live CPU, memory, and network metrics for containers and get alerts for problems on Discord, Slack, Telegram, Pushover, Gotify, and SMTP with customizable templates. Give it a try especially when most of developers don’t need and use the k8s cluster. This is a handy tool.

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.
