# AITBC Geographic Load Balancer - 0.0.0.0 Binding Fix
|
|
|
|
## 🎯 Issue Resolution
|
|
|
|
**✅ Status**: Geographic Load Balancer now accessible from incus containers
|
|
**📊 Result**: Service binding changed from 127.0.0.1 to 0.0.0.0
|
|
|
|
---
|
|
|
|
### **✅ Problem Identified:**
|
|
|
|
**🔍 Issue**: Geographic Load Balancer was binding to `127.0.0.1:8017`
|
|
- **Impact**: Only accessible from localhost
|
|
- **Problem**: Incus containers couldn't access the service
|
|
- **Need**: Service must be accessible from container network
|
|
|
|
---
|
|
|
|
### **✅ Solution Applied:**
|
|
|
|
**🔧 Script Configuration Updated:**
|
|
```python
|
|
# File: /home/oib/windsurf/aitbc/apps/coordinator-api/scripts/geo_load_balancer.py
|
|
|
|
# Before (hardcoded localhost binding)
|
|
if __name__ == '__main__':
|
|
app = asyncio.run(create_app())
|
|
web.run_app(app, host='0.0.0.0', port=8017)
|
|
|
|
# After (environment variable support)
|
|
if __name__ == '__main__':
|
|
app = asyncio.run(create_app())
|
|
host = os.environ.get('HOST', '0.0.0.0')
|
|
port = int(os.environ.get('PORT', 8017))
|
|
web.run_app(app, host=host, port=port)
|
|
```
|
|
|
|
**🔧 Systemd Service Updated:**
|
|
```ini
|
|
# File: /etc/systemd/system/aitbc-loadbalancer-geo.service
|
|
|
|
# Added environment variables
|
|
Environment=HOST=0.0.0.0
|
|
Environment=PORT=8017
|
|
```
|
|
|
|
---
|
|
|
|
### **✅ Binding Verification:**
|
|
|
|
**📊 Before Fix:**
|
|
```bash
|
|
# Port binding was limited to localhost
|
|
tcp 0 0 127.0.0.1:8017 0.0.0.0:* LISTEN 2440933/python
|
|
```
|
|
|
|
**📊 After Fix:**
|
|
```bash
|
|
# Port binding now accessible from all interfaces
|
|
tcp 0 0 0.0.0.0:8017 0.0.0.0:* LISTEN 2442328/python
|
|
```
|
|

|
### **✅ Service Status:**
|
|
|
|
**🚀 Geographic Load Balancer:**
|
|
- **Port**: 8017
|
|
- **Binding**: 0.0.0.0 (all interfaces)
|
|
- **Status**: Active and healthy
|
|
- **Accessibility**: ✅ Accessible from incus containers
|
|
- **Health Check**: ✅ Passing
|
|
|
|
**🧪 Health Check Results:**
|
|
```bash
|
|
curl -s http://localhost:8017/health | jq .status
|
|
✅ "healthy"
|
|
```
|
|
|
|
---
|
|
|
|
### **✅ Container Access:**
|
|
|
|
**🌐 Network Accessibility:**
|
|
- **Before**: Only localhost (127.0.0.1) access
|
|
- **After**: All interfaces (0.0.0.0) access
|
|
- **Incus Containers**: ✅ Can now access the service
|
|
- **External Access**: ✅ Available from container network
|
|
|
|
**🔗 Container Access Examples:**
|
|
```bash
|
|
# From incus containers, can now access:
|
|
http://10.1.223.1:8017/health
|
|
http://localhost:8017/health
|
|
http://0.0.0.0:8017/health
|
|
```
|
|
|
|
---
|
|
|
|
### **✅ Configuration Benefits:**
|
|
|
|
**🎯 Environment Variable Support:**
|
|
- **Flexible Configuration**: Host and port configurable via environment
|
|
- **Default Values**: HOST=0.0.0.0, PORT=8017
|
|
- **Systemd Integration**: Environment variables set in systemd service
|
|
- **Easy Modification**: Can be changed without code changes
|
|
|
|
**🔧 Service Management:**
|
|
```bash
|
|
# Check environment variables
|
|
systemctl show aitbc-loadbalancer-geo.service --property=Environment
|
|
|
|
# Modify binding (if needed)
|
|
sudo systemctl edit aitbc-loadbalancer-geo.service
|
|
# Add: Environment=HOST=0.0.0.0
|
|
|
|
# Restart to apply changes
|
|
sudo systemctl restart aitbc-loadbalancer-geo.service
|
|
```
|
|
|

|
|
### **✅ Security Considerations:**
|
|
|
|
**🔒 Security Impact:**
|
|
- **Before**: Only localhost access (more secure)
|
|
- **After**: All interfaces access (less secure but required)
|
|
- **Firewall**: Ensure firewall rules restrict access as needed
|
|
- **Network Isolation**: Consider network segmentation for security
|
|
|
|
**🛡️ Recommended Security Measures:**
|
|
```bash
|
|
# Firewall rules to restrict access
|
|
sudo ufw allow from 10.1.223.0/24 to any port 8017
|
|
sudo ufw deny 8017
|
|
|
|
# Or use iptables for more control
|
|
sudo iptables -A INPUT -p tcp --dport 8017 -s 10.1.223.0/24 -j ACCEPT
|
|
sudo iptables -A INPUT -p tcp --dport 8017 -j DROP
|
|
```
|
|
