HAProxy Manager Upgrade Summary

This document summarizes the new features and improvements added to the HAProxy Manager project.

New Features Implemented

1. API Key Authentication

  • Feature: Optional API key authentication for all API endpoints
  • Implementation:
    • Environment variable HAPROXY_API_KEY controls authentication
    • Bearer token authentication using Authorization: Bearer <key> header
    • Health check endpoint (/health) and web UI (/) remain unauthenticated
    • Graceful fallback to unauthenticated mode when no API key is set
  • Security: All API endpoints (except health check) require authentication when API key is configured

2. Certificate Renewal API

  • Endpoint: POST /api/certificates/renew
  • Functionality:
    • Triggers renewal of all Let's Encrypt certificates
    • Automatically updates combined certificate files for HAProxy
    • Regenerates HAProxy configuration
    • Reloads HAProxy with new certificates
    • Returns detailed status of renewal process
  • Error Handling: Comprehensive error logging and status reporting

3. Certificate Request API

  • Endpoint: POST /api/certificates/request
  • Functionality:
    • Request certificate generation for one or more domains
    • Support for multiple domains in a single request
    • Optional www subdomain inclusion
    • Force renewal option
    • Automatic domain addition to database if not exists
    • Batch processing with detailed results
  • Use Case: Allow other services to request certificate generation through the HAProxy service
  • Response: Detailed status for each domain with success/failure information

4. Certificate Download Endpoints

  • Endpoints:
    • GET /api/certificates/<domain>/download - Combined certificate (cert + key)
    • GET /api/certificates/<domain>/key - Private key only
    • GET /api/certificates/<domain>/cert - Certificate only (no private key)
  • Use Case: Allow other services to securely download certificates for their own use
  • Security: All endpoints require API key authentication

5. Certificate Status Monitoring

  • Endpoint: GET /api/certificates/status
  • Functionality:
    • Lists all certificates with expiration dates
    • Calculates days until expiration
    • Provides certificate file paths
    • Enables proactive certificate management

6. Comprehensive Error Logging and Alerting

  • Logging System:
    • Structured JSON logging for all operations
    • Separate error log file (/var/log/haproxy-manager-errors.log)
    • General application log (/var/log/haproxy-manager.log)
    • Timestamped operation tracking
  • Alerting Capabilities:
    • Error detection and logging
    • Certificate expiration warnings
    • HAProxy operation failure tracking
    • Configurable alerting via monitoring script

Technical Improvements

Enhanced Error Handling

  • All API endpoints now include comprehensive error handling
  • Detailed error messages with logging
  • Graceful failure handling for HAProxy operations
  • Certificate operation error tracking

Improved Logging

  • Structured logging with timestamps
  • Operation success/failure tracking
  • Error categorization and alerting
  • Debug information for troubleshooting

Better HAProxy Integration

  • Enhanced configuration validation
  • Improved reload/restart handling
  • Better error reporting for HAProxy operations
  • Automatic recovery from configuration errors

New Scripts and Tools

1. Monitoring Script (scripts/monitor-errors.sh)

  • Purpose: Monitor error logs and certificate expiration
  • Features:
    • Check for recent errors in configurable time windows
    • Monitor certificate expiration dates
    • Email and webhook alerting capabilities
    • Configurable thresholds and intervals
  • Usage: Can be integrated with cron for automated monitoring

2. API Test Script (scripts/test-api.sh)

  • Purpose: Test all new API endpoints
  • Features:
    • Comprehensive API endpoint testing
    • Authentication testing
    • Colored output for easy reading
    • Detailed response logging

3. Monitoring Configuration (scripts/monitoring-example.conf)

  • Purpose: Example configuration for monitoring setup
  • Features:
    • Email and webhook configuration examples
    • Crontab entry examples
    • Monitoring interval recommendations

Updated Files

Core Application

  • haproxy_manager.py - Major updates with new endpoints and features
  • requirements.txt - No changes needed (existing dependencies sufficient)
  • Dockerfile - Added jq package and log directory setup

Documentation

  • README.md - Comprehensive updates with new feature documentation
  • UPGRADE_SUMMARY.md - This summary document

Scripts

  • scripts/monitor-errors.sh - New monitoring and alerting script
  • scripts/test-api.sh - New API testing script
  • scripts/monitoring-example.conf - New monitoring configuration example

Environment Variables

Variable Description Default Required
HAPROXY_API_KEY API key for authentication None No (optional)

Migration Guide

For Existing Users

  1. No Breaking Changes: Existing functionality remains unchanged
  2. Optional Authentication: API key is optional - set HAPROXY_API_KEY to enable
  3. Backward Compatibility: All existing endpoints work without authentication when no API key is set

For New Deployments

  1. Recommended: Set HAPROXY_API_KEY for production deployments
  2. Monitoring: Configure monitoring script for automated alerting
  3. Testing: Use test script to verify all endpoints work correctly

API Endpoints Summary

Existing Endpoints (Updated with Authentication)

  • GET /health - Health check (no auth required)
  • GET /api/domains - List domains
  • POST /api/domain - Add domain
  • DELETE /api/domain - Remove domain
  • POST /api/ssl - Request SSL certificate
  • GET /api/regenerate - Regenerate configuration
  • GET /api/reload - Reload HAProxy

New Endpoints

  • POST /api/certificates/request - Request certificate generation for domains
  • POST /api/certificates/renew - Renew all certificates
  • GET /api/certificates/status - Get certificate status
  • GET /api/certificates/<domain>/download - Download combined certificate
  • GET /api/certificates/<domain>/key - Download private key
  • GET /api/certificates/<domain>/cert - Download certificate only

Security Considerations

  1. API Key Security: Use strong, unique API keys for production
  2. Network Security: Restrict access to port 8000 using firewalls
  3. Certificate Security: Private key endpoints require authentication
  4. Log Security: Monitor log files for sensitive information

Monitoring and Alerting

  1. Error Monitoring: Monitor /var/log/haproxy-manager-errors.log
  2. Certificate Monitoring: Use certificate status endpoint for expiration tracking
  3. HAProxy Monitoring: Health check endpoint provides service status
  4. Automated Alerting: Configure monitoring script with email/webhook alerts

Future Enhancements

Potential areas for future development:

  1. Webhook integration for certificate renewal notifications
  2. Advanced certificate management (wildcard certificates, etc.)
  3. HAProxy statistics and monitoring endpoints
  4. Configuration backup and restore functionality
  5. Multi-tenant support with per-domain API keys
