# 🎉 Node Registry Service — Final Summary
|
||||
|
||||
**Project:** Node Registry Service для DAGI Stack
|
||||
**Version:** 1.0.0
|
||||
**Status:** ✅ **COMPLETE & PRODUCTION READY**
|
||||
**Date:** 2025-01-17
|
||||
|
||||
---
|
||||
|
||||
## 📋 Project Overview
|
||||
|
||||
Node Registry Service — централізований реєстр для управління всіма нодами DAGI мережі (Node #1, Node #2, майбутні Node #N).
|
||||
|
||||
### Key Features
|
||||
- **Node Registration** — автоматична/ручна реєстрація нод
|
||||
- **Heartbeat Tracking** — моніторинг стану та доступності
|
||||
- **Node Discovery** — пошук нод за роллю, мітками, статусом
|
||||
- **Profile Management** — конфігураційні профілі для ролей
|
||||
- **DAGI Router Integration** — повна інтеграція для node-aware routing
|
||||
|
||||

|
||||
### Phase 2: Full Implementation (by Cursor)
|
||||
|
||||
**Backend API**
|
||||
- ✅ SQLAlchemy ORM models (`models.py`)
|
||||
- `Node` model (node_id, hostname, ip, role, labels, status, heartbeat)
|
||||
- `NodeProfile` model (role-based configuration profiles)
|
||||
- ✅ Pydantic request/response schemas (`schemas.py`)
|
||||
- ✅ CRUD operations (`crud.py`)
|
||||
- `register_node()` with auto node_id generation
|
||||
- `update_heartbeat()` with timestamp updates
|
||||
- `get_node()`, `list_nodes()` with filtering
|
||||
- `get_node_profile()` for role configs
|
||||
- ✅ Database connection pool with async PostgreSQL
|
||||
- ✅ SQL migration (`001_create_node_registry_tables.sql`)
|
||||
|
||||
**API Endpoints** (8 endpoints)
|
||||
```
|
||||
GET /health - Health check with DB status
|
||||
GET /metrics - Prometheus metrics
|
||||
GET / - Service information
|
||||
POST /api/v1/nodes/register - Register/update node
|
||||
POST /api/v1/nodes/heartbeat - Update heartbeat
|
||||
GET /api/v1/nodes - List nodes (filters: role, label, status)
|
||||
GET /api/v1/nodes/{node_id} - Get node details
|
||||
GET /api/v1/profiles/{role} - Get role profile
|
||||
```
|
||||
|
||||
**Bootstrap Tool**
|
||||
- ✅ DAGI Node Agent Bootstrap (`tools/dagi_node_agent/bootstrap.py`)
|
||||
- Automatic hostname and IP detection
|
||||
- Registration with Node Registry
|
||||
- Local node_id storage (`/etc/dagi/node_id` or `~/.config/dagi/node_id`)
|
||||
- Initial heartbeat after registration
|
||||
- CLI interface with role and labels support

|
||||
### Phase 3: DAGI Router Integration (by Cursor)
|
||||
|
||||
**Node Registry Client**
|
||||
- ✅ Async HTTP client (`utils/node_registry_client.py`)
|
||||
- `get_nodes()` — fetch all nodes
|
||||
- `get_node(node_id)` — fetch specific node
|
||||
- `get_nodes_by_role(role)` — filter by role
|
||||
- `get_available_nodes(role, label, status)` — advanced filtering
|
||||
- Graceful degradation when service unavailable
|
||||
- Error handling and automatic retries
|
||||
|
||||
**Router Integration**
|
||||
- ✅ `router_app.py` updated
|
||||
- Added `get_available_nodes()` method
|
||||
- Node discovery for intelligent routing decisions
|
||||
- ✅ `http_api.py` updated
|
||||
- New endpoint: `GET /nodes?role=xxx` (proxy to Node Registry)
|
||||
- Accessible at http://localhost:9102/nodes
|
||||
|
||||
**Test Scripts**
|
||||
- ✅ `scripts/test_node_registry.sh` — API endpoint testing
|
||||
- ✅ `scripts/test_bootstrap.sh` — Bootstrap tool testing
|
||||
- ✅ `scripts/init_node_registry_db.sh` — Database initialization

|
||||
|
||||
## 🚀 Quick Start Guide
|
||||
|
||||
### Prerequisites
|
||||
- Docker & Docker Compose
|
||||
- PostgreSQL database (`city-db` or similar)
|
||||
- Python 3.11+
|
||||
|
||||
### 1. Initialize Database
|
||||
```bash
|
||||
# Option A: Using script
|
||||
./scripts/init_node_registry_db.sh
|
||||
|
||||
# Option B: Manual
|
||||
docker exec -it dagi-city-db psql -U postgres -c "CREATE DATABASE node_registry;"
|
||||
docker exec -i dagi-city-db psql -U postgres -d node_registry < \
|
||||
services/node-registry/migrations/001_create_node_registry_tables.sql
|
||||
```
|
||||
|
||||
### 2. Start Service
|
||||
```bash
|
||||
# Start Node Registry
|
||||
docker-compose up -d node-registry
|
||||
|
||||
# Check logs
|
||||
docker logs -f dagi-node-registry
|
||||
|
||||
# Verify health
|
||||
curl http://localhost:9205/health
|
||||
```
|
||||
|
||||
### 3. Test API
|
||||
```bash
|
||||
# Run automated tests
|
||||
./scripts/test_node_registry.sh
|
||||
|
||||
# Manual test - register node
|
||||
curl -X POST http://localhost:9205/api/v1/nodes/register \
|
||||
-H "Content-Type: application/json" \
|
||||
-d '{"hostname": "test", "ip": "192.168.1.1", "role": "test-node", "labels": ["test"]}'
|
||||
|
||||
# List nodes
|
||||
curl http://localhost:9205/api/v1/nodes
|
||||
```
|
||||
|
||||
### 4. Register Nodes with Bootstrap
|
||||
```bash
|
||||
# Node #1 (Production)
|
||||
python3 -m tools.dagi_node_agent.bootstrap \
|
||||
--role production-router \
|
||||
--labels router,gateway,production \
|
||||
--registry-url http://localhost:9205
|
||||
|
||||
# Node #2 (Development)
|
||||
python3 -m tools.dagi_node_agent.bootstrap \
|
||||
--role development-router \
|
||||
--labels router,development,mac,gpu \
|
||||
--registry-url http://192.168.1.244:9205
|
||||
```
|
||||
|
||||
### 5. Query from DAGI Router
|
||||
```bash
|
||||
# List all nodes via Router
|
||||
curl http://localhost:9102/nodes
|
||||
|
||||
# Filter by role
|
||||
curl http://localhost:9102/nodes?role=production-router
|
||||
```

||||
"timestamp": "2025-01-17T14:30:00Z"
|
||||
}
|
||||
```
|
||||
|
||||
### Prometheus Integration (Future)
|
||||
```yaml
|
||||
scrape_configs:
|
||||
- job_name: 'node-registry'
|
||||
static_configs:
|
||||
- targets: ['node-registry:9205']
|
||||
scrape_interval: 30s
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 🔐 Security
|
||||
|
||||
### Network Access
|
||||
- **Port 9205:** Internal network only (Node #1, Node #2, DAGI nodes)
|
||||
- **Firewall:** UFW rules block external access
|
||||
- **No public internet access** to Node Registry
|
||||
|
||||
### Authentication
|
||||
- ⚠️ **Current:** No authentication (internal network trust)
|
||||
- 🔄 **Future:** API key authentication, JWT tokens, rate limiting
|
||||
|
||||
### Firewall Rules
|
||||
```bash
|
||||
# Allow from LAN
|
||||
ufw allow from 192.168.1.0/24 to any port 9205 proto tcp
|
||||
|
||||
# Allow from Docker network
|
||||
ufw allow from 172.16.0.0/12 to any port 9205 proto tcp
|
||||
|
||||
# Deny from external
|
||||
ufw deny 9205/tcp
|
||||
```

## 🎯 Use Cases
|
||||
|
||||
### 1. Node Discovery for Routing
|
||||
```python
|
||||
# In DAGI Router
|
||||
from utils.node_registry_client import NodeRegistryClient
|
||||
|
||||
client = NodeRegistryClient("http://node-registry:9205")
|
||||
nodes = await client.get_nodes_by_role("heavy-vision-node")
|
||||
# Select node with GPU for vision tasks
|
||||
```
|
||||
|
||||
### 2. Health Monitoring
|
||||
```bash
|
||||
# Check all node heartbeats
|
||||
curl http://localhost:9205/api/v1/nodes | jq '.[] | {node_id, status, last_heartbeat}'
|
||||
```
|
||||
|
||||
### 3. Automated Registration
|
||||
```bash
|
||||
# On new node setup
|
||||
python3 -m tools.dagi_node_agent.bootstrap \
|
||||
--role worker-node \
|
||||
--labels cpu,background-tasks
|
||||
```
|
||||
|
||||
### 4. Load Balancing
|
||||
```python
|
||||
# Get available nodes and load balance
|
||||
nodes = await client.get_available_nodes(
|
||||
role="inference-node",
|
||||
label="gpu",
|
||||
status="online"
|
||||
)
|
||||
selected_node = random.choice(nodes) # or use load balancing algorithm
|
||||
```
|
||||
|
||||
