-
|
| 15 |
-
```bash
|
| 16 |
-
# Clone or navigate to the project directory
|
| 17 |
-
cd /path/to/nz-legislation-analyzer
|
| 18 |
-
|
| 19 |
-
# Build and run the application
|
| 20 |
-
docker-compose up --build
|
| 21 |

| 42 |
-
|
| 43 |
-

|
| 126 |
-
|
| 127 |

-
|
| 129 |
-
```bash
|
| 130 |
-
# Docker Compose logs
|
| 131 |

|
| 139 |
-
|
| 140 |
-
### Health Checks
|
| 141 |
-
|
| 142 |
-
The Docker Compose setup includes health checks that monitor the Streamlit application:
|
| 143 |
-
|
| 144 |
-
```yaml
|
| 145 |
-
healthcheck:
|
| 146 |
-
test: ["CMD", "curl", "-f", "http://localhost:8501/healthz"]
|
| 147 |
-
interval: 30s
|
| 148 |
-
timeout: 10s
|
| 149 |
-
retries: 3
|
| 150 |
-
start_period: 40s
|
| 151 |
-
```
|
| 152 |
-
|
| 153 |
-
## π Troubleshooting
|
| 154 |
-
|
| 155 |
-
### Common Issues
|
| 156 |
-
|
| 157 |
-
1. **Port Already in Use**
|
| 158 |
-
```bash
|
| 159 |
-
# Change the port mapping
|
| 160 |
-
docker run -p 8502:8501 nz-legislation-analyzer
|
| 161 |
-
# Or with docker-compose, modify the ports section
|
| 162 |
-
```
|
| 163 |
-
|
| 164 |
-
2. **Memory Issues**
|
| 165 |
-
```bash
|
| 166 |
-
# Increase Docker memory allocation
|
| 167 |
-
# Docker Desktop: Settings > Resources > Memory
|
| 168 |
-
# Or add memory limits to docker-compose.yml
|
| 169 |
-
```
|
| 170 |
-
|
| 171 |
-
3. **Model Loading Errors**
|
| 172 |
-
- Ensure sufficient RAM (8GB+ recommended)
|
| 173 |
-
- Check that model files are accessible
|
| 174 |
-
- Verify model path in configuration
|
| 175 |
-
|
| 176 |
-
4. **Permission Issues**
|
| 177 |
-
```bash
|
| 178 |
-
# Fix directory permissions
|
| 179 |
-
sudo chown -R $USER:$USER streamlit_app/
|
| 180 |
-
```
|
| 181 |
-
|
| 182 |
-
5. **Cache Issues**
|
| 183 |
-
```bash
|
| 184 |
-
# Clear persistent cache
|
| 185 |
-
sudo rm -rf streamlit_app/cache/*
|
| 186 |
-
docker-compose restart
|
| 187 |
-
```
|
| 188 |
-
|
| 189 |
-
### Debug Mode
|
| 190 |
-
|
| 191 |
-
Enable debug logging by modifying the environment:
|
| 192 |
-
|
| 193 |
-
```bash
|
| 194 |
-
# Add to docker-compose.yml environment section
|
| 195 |
-
- PYTHONPATH=/app
|
| 196 |
-
- LOG_LEVEL=DEBUG
|
| 197 |
-
```
|
| 198 |
-
|
| 199 |
-
## π Updates and Maintenance
|
| 200 |
-
|
| 201 |
-
### Updating the Application
|
| 202 |
-
|
| 203 |
-
```bash
|
| 204 |
-
# Pull latest changes
|
| 205 |
-
git pull
|
| 206 |
-
|
| 207 |
-
# Rebuild the image
|
| 208 |
-
docker-compose build --no-cache
|
| 209 |
-
|
| 210 |
-
# Restart services
|
| 211 |
-
docker-compose up -d
|
| 212 |
-
```
|
| 213 |
-
|
| 214 |
-
### Backup Important Data
|
| 215 |
-
|
| 216 |
-
```bash
|
| 217 |
-
# Backup cache and configuration
|
| 218 |
-
tar -czf backup.tar.gz streamlit_app/cache/ streamlit_app/config/
|
| 219 |
-
|
| 220 |
-
# Backup datasets
|
| 221 |
-
tar -czf datasets_backup.tar.gz streamlit_app/datasets/
|
| 222 |
-
```
|
| 223 |
-
|
| 224 |
-
### Cleaning Up
|
| 225 |
-
|
| 226 |
-
```bash
|
| 227 |
-
# Remove containers and volumes
|
| 228 |
-
docker-compose down -v
|
| 229 |
-
|
| 230 |
-
# Remove images
|
| 231 |
-
docker rmi nz-legislation-analyzer
|
| 232 |
-
|
| 233 |
-
# Clean up unused Docker resources
|
| 234 |
-
docker system prune -a
|
| 235 |
-
```
|
| 236 |
-
|
| 237 |
-
## ποΈ Advanced Configuration
|
| 238 |
-
|
| 239 |
-
### Custom Model Files
|
| 240 |
-
|
| 241 |
-
To use custom model files:
|
| 242 |
-
|
| 243 |
-
1. **Mount model directory:**
|
| 244 |
-
```yaml
|
| 245 |
-
volumes:
|
| 246 |
-
- ./models:/app/models:ro
|
| 247 |
-
```
|
| 248 |
-
|
| 249 |
-
2. **Update configuration** in the Streamlit app to point to `/app/models/your-model.gguf`
|
| 250 |
-
|
| 251 |
-
### GPU Support (Optional)
|
| 252 |
-
|
| 253 |
-
For GPU acceleration with CUDA:
|
| 254 |
-
|
| 255 |
-
```dockerfile
|
| 256 |
-
# Use CUDA-enabled base image
|
| 257 |
-
FROM nvidia/cuda:11.8-devel-ubuntu22.04
|
| 258 |
-
|
| 259 |
-
# Install Python and dependencies
|
| 260 |
-
# ... (additional setup for CUDA)
|
| 261 |
-
```
|
| 262 |
-
|
| 263 |
-
Note: GPU support requires additional configuration and CUDA-compatible hardware.
|
| 264 |
-
|
| 265 |
-
## π Security Considerations
|
| 266 |
-
|
| 267 |
-
- The application runs in headless mode by default
|
| 268 |
-
- All data is stored locally in mounted volumes
|
| 269 |
-
- No external network access is required for basic functionality
|
| 270 |
-
- Consider implementing authentication for production deployments
|
| 271 |
-
|
| 272 |
-
## π Performance Optimization
|
| 273 |
-
|
| 274 |
-
### Memory Management
|
| 275 |
-
|
| 276 |
-
- Default cache size: 1024MB (configurable in app settings)
|
| 277 |
-
- Adjust based on available system memory
|
| 278 |
-
- Monitor memory usage through the app's Performance dashboard
|
| 279 |
-
|
| 280 |
-
### Disk I/O
|
| 281 |
-
|
| 282 |
-
- Use SSD storage for better performance
|
| 283 |
-
- Ensure adequate disk space for cache and datasets
|
| 284 |
-
- Consider using tmpfs for temporary processing
|
| 285 |
-
|
| 286 |
-
### Network
|
| 287 |
-
|
| 288 |
-
- The application binds to all interfaces (`0.0.0.0`)
|
| 289 |
-
- Access via `localhost` or container IP
|
| 290 |
-
- No external dependencies required
|
| 291 |
-
|
| 292 |
-
## π Support
|
| 293 |
-
|
| 294 |
-
For Docker-specific issues:
|
| 295 |
-
|
| 296 |
-
1. Check Docker logs: `docker-compose logs`
|
| 297 |
-
2. Verify Docker installation and version
|
| 298 |
-
3. Ensure adequate system resources
|
| 299 |
-
4. Review the main application logs in `streamlit_app/logs/`
|
| 300 |
-
|
| 301 |
-
For application-specific issues, refer to the main documentation in `README_Streamlit_App.md`.
