ERPNext Docker Deployment for Hanzo

Self-initializing Docker configurations for deploying ERPNext on Hanzo. No manual setup required - just deploy and go!

🌐 Environments

• Production: https://erp.hanzo.ai (single domain for all services)
• Development: https://erp-dev.hanzo.ai (single domain for all services)

📁 Files

• compose.prod.yml - Production Docker Compose (self-initializing)
• compose.dev.yml - Development Docker Compose (self-initializing)
• ENVIRONMENT_VARIABLES.md - Environment variables reference
• ROUTING_ARCHITECTURE.md - How routing and services work
• HANZO_DEPLOYMENT.md - Detailed deployment guide

🚀 Quick Start

1. Set Environment Variables in Hanzo

In your Hanzo/Dokploy UI, set these two variables:

DB_PASSWORD=<generate_secure_password>
ADMIN_PASSWORD=<your_admin_password>

Generate a secure DB_PASSWORD:

openssl rand -base64 32

2. Deploy

1. Create new app in Hanzo
2. Choose "Docker Compose" deployment type
3. Upload the appropriate compose file:
   • Production: compose.prod.yml
   • Development: compose.dev.yml
4. Click Deploy

That's it! The system will automatically:

• Configure all services
• Create the database
• Initialize the ERPNext site
• Set up the scheduler
• Configure production/development settings

3. Access Your Instance

Once deployment is complete (3-5 minutes):

• Production: https://erp.hanzo.ai
• Development: https://erp-dev.hanzo.ai

Login with:

• Username: Administrator
• Password: The ADMIN_PASSWORD you set in Hanzo

🔧 Architecture

Each environment includes:

• MariaDB - Database server
• Redis (2 instances) - Cache and queue management
• Backend - Frappe/ERPNext application server
• Frontend - Nginx web server (only service exposed via Traefik)
• WebSocket - Real-time communication
• Workers - Background job processors (short & long queues)
• Scheduler - Scheduled task runner
• Configurator - One-time setup service (auto-creates site)

Note: All traffic routes through the Frontend service. No additional domains or ports needed!

🔐 Security Features

• External hanzo-network for isolation
• Traefik SSL/TLS termination
• Content Security Policy headers
• HTTPS redirect middleware
• tmpfs for temporary files

📊 Resource Allocation

Production

• MariaDB: 1GB buffer pool, 200 max connections
• Redis Cache: 512MB max memory
• Production mode enabled

Development

• MariaDB: 512MB buffer pool, 100 max connections
• Redis Cache: 256MB max memory
• Developer mode enabled

🛠️ Maintenance

Backup

# Find your backend container
docker ps | grep backend

# Run backup
docker exec <backend-container> bench --site <domain> backup --with-files

Clear Cache

docker exec <backend-container> bench --site <domain> clear-cache

View Logs

# All services
docker-compose -f compose.prod.yml logs

# Specific service
docker logs <container-name> -f

Update ERPNext Version

1. Update the image tag in compose file (all services use same version)
2. Redeploy in Hanzo
3. System will automatically run migrations

🐛 Troubleshooting

Check Service Health

docker ps

Database Issues

Check the configurator logs - it handles all initialization:

docker logs <configurator-container>

Frontend Not Accessible

• Verify Traefik labels in compose file
• Check domain configuration in Hanzo
• Ensure hanzo-network exists
