# 🔧 Node Registry Service — Status & Deployment
|
||||
|
||||
**Версія:** 1.0.0
|
||||
**Дата створення:** 2025-01-17
|
||||
**Останнє оновлення:** 2025-01-17
|
||||
**Статус:** ✅ Complete + Integrated — Full Stack Implementation Ready for Production
|
||||
|
||||
---
|
||||
|
||||
## 📋 Overview
|
||||
|
||||
Node Registry Service — централізований реєстр для всіх нод DAGI мережі (Node #1, Node #2, майбутні Node #N).
|
||||
|
||||
### Призначення
|
||||
- **Реєстрація нод** — автоматична/ручна реєстрація нових нод
|
||||
- **Heartbeat tracking** — моніторинг доступності та здоров'я нод
|
||||
- **Node discovery** — пошук доступних нод та їх можливостей
|
||||
- **Profile management** — збереження профілів нод (LLM configs, services, capabilities)
|
||||
|
||||

## 🚀 Deployment
|
||||
|
||||
### Quick Deploy to Node #1 (Production)
|
||||
|
||||
```bash
|
||||
# From Node #2 (MacBook)
|
||||
cd /Users/apple/github-projects/microdao-daarion
|
||||
|
||||
# Deploy service
|
||||
./scripts/deploy-node-registry.sh
|
||||
|
||||
# Register Node #1 using bootstrap
|
||||
python -m tools.dagi_node_agent.bootstrap \
|
||||
--role production-router \
|
||||
--labels router,gateway,production \
|
||||
--registry-url http://144.76.224.179:9205
|
||||
|
||||
# Register Node #2 using bootstrap
|
||||
python -m tools.dagi_node_agent.bootstrap \
|
||||
--role development-router \
|
||||
--labels router,development,mac,gpu \
|
||||
--registry-url http://192.168.1.244:9205
|
||||
```
|
||||
|
||||
### Manual Deployment Steps
|
||||
|
||||
#### 1. Initialize Database (on Node #1)
|
||||
```bash
|
||||
ssh root@144.76.224.179
|
||||
cd /opt/microdao-daarion
|
||||
|
||||
# Copy SQL script to container
|
||||
docker cp services/node-registry/migrations/init_node_registry.sql dagi-postgres:/tmp/
|
||||
|
||||
# Run initialization
|
||||
docker exec -i dagi-postgres psql -U postgres < /tmp/init_node_registry.sql
|
||||
```
|
||||
|
||||
#### 2. Generate Secure Password
|
||||
```bash
|
||||
# Generate and save to .env
|
||||
PASSWORD=$(openssl rand -base64 32)
|
||||
echo "NODE_REGISTRY_DB_PASSWORD=$PASSWORD" >> .env
|
||||
```
|
||||
|
||||
#### 3. Build and Start
|
||||
```bash
|
||||
# Build Docker image
|
||||
docker-compose build node-registry
|
||||
|
||||
# Start service
|
||||
docker-compose up -d node-registry
|
||||
|
||||
# Check status
|
||||
docker-compose ps | grep node-registry
|
||||
docker logs dagi-node-registry
|
||||
```
|
||||
|
||||
#### 4. Configure Firewall
|
||||
```bash
|
||||
# Allow internal access
|
||||
ufw allow from 192.168.1.0/24 to any port 9205 proto tcp
|
||||
ufw allow from 172.16.0.0/12 to any port 9205 proto tcp
|
||||
|
||||
# Deny external
|
||||
ufw deny 9205/tcp
|
||||
```
|
||||
|
||||
#### 5. Verify Deployment
|
||||
```bash
|
||||
# Health check
|
||||
curl http://localhost:9205/health
|
||||
|
||||
# Expected response:
|
||||
# {"status":"healthy","service":"node-registry","version":"0.1.0-stub",...}
|
||||
```
|
||||

## ⚠️ Security Considerations
|
||||
|
||||
### Network Security
|
||||
- ✅ Port 9205 accessible only from internal network
|
||||
- ✅ Firewall rules configured (UFW)
|
||||
- ⚠️ No authentication yet (to be added by Cursor)
|
||||
|
||||
### Database Security
|
||||
- ✅ Secure password generated automatically
|
||||
- ✅ Dedicated database user with limited privileges
|
||||
- ✅ Password stored in `.env` (not committed to git)
|
||||
|
||||
### Future Improvements
|
||||
- [ ] API key authentication
|
||||
- [ ] TLS/SSL for API communication
|
||||
- [ ] Rate limiting per node
|
||||
- [ ] Audit logging for node changes
