# Server Cleanup Commands
Before deploying a new version, you can use these commands to completely clean up old builds and free disk space.
## 🧹 Complete Cleanup (Nuclear Option)
Run these commands on the Ubuntu server **before** running `deploy.sh`:
```bash
# Navigate to project directory
cd /opt/solventum-image-metadata
# Stop all running containers
sudo docker-compose -f docker-compose.fastapi.yml down --remove-orphans
# Remove ALL Oliver Metadata related containers (including stopped ones)
sudo docker ps -a | grep -E "oliver|solventum-image-metadata" | awk '{print $1}' | xargs -r sudo docker rm -f
# Remove ALL Oliver Metadata related images
sudo docker images | grep -E "oliver|solventum-image-metadata" | awk '{print $3}' | xargs -r sudo docker rmi -f
# Remove ALL Oliver Metadata related volumes (⚠️ WARNING: This deletes database data!)
sudo docker volume ls | grep oliver | awk '{print $2}' | xargs -r sudo docker volume rm
# Clean Docker build cache
sudo docker builder prune -af
# Remove dangling images
sudo docker image prune -af
# Remove unused networks
sudo docker network prune -f
# Remove stopped containers
sudo docker container prune -f
```
## 🗑️ Safe Cleanup (Keeps Database & Uploads)
If you want to keep your database and uploaded files:
```bash
cd /opt/solventum-image-metadata
# Stop containers
sudo docker-compose -f docker-compose.fastapi.yml down
# Remove only old images (not volumes)
sudo docker images | grep -E "oliver|solventum-image-metadata" | awk '{print $3}' | xargs -r sudo docker rmi -f
# Clean build cache (keep last 24 hours)
sudo docker builder prune -f --filter "until=24h"
# Clean system
sudo docker system prune -f
```
## 📊 Check Disk Space
```bash
# Before cleanup
df -h /var/lib/docker
# Check Docker disk usage
sudo docker system df
# After cleanup
sudo docker system df
```
## 🔍 Verify Cleanup
```bash
# Should return no Oliver containers
sudo docker ps -a | grep -E "oliver|solventum"
# Should return no Oliver images
sudo docker images | grep -E "oliver|solventum"
# List remaining volumes (should see redis-data if you kept volumes)
sudo docker volume ls | grep oliver
```
## 🚀 Full Deployment Workflow
Complete workflow for a fresh deployment:
```bash
# 1. Navigate to project
cd /opt/solventum-image-metadata
# 2. OPTIONAL: Backup database (recommended)
sudo cp backend/data/oliver_metadata.db backend/data/oliver_metadata.db.backup-$(date +%Y%m%d-%H%M%S)
# 3. Run safe cleanup
sudo docker-compose -f docker-compose.fastapi.yml down
sudo docker images | grep -E "oliver|solventum" | awk '{print $3}' | xargs -r sudo docker rmi -f
sudo docker system prune -f
# 4. Run deployment script (includes git pull)
sudo ./deploy.sh
```
## ⚠️ WARNING: Data Loss Commands
These commands will **PERMANENTLY DELETE** your data:
```bash
# Delete database (cannot be recovered unless backed up)
sudo rm -rf /opt/solventum-image-metadata/backend/data/oliver_metadata.db
# Delete all uploads (cannot be recovered)
sudo rm -rf /opt/solventum-image-metadata/backend/uploads/*
# Delete all volumes (includes Redis data)
sudo docker volume rm $(sudo docker volume ls | grep oliver | awk '{print $2}')
# Delete all frontend files
sudo rm -rf /var/www/html/solventum-image-metadata/*
```
## 🔧 Troubleshooting
### "Device or resource busy" error
If you get errors removing images/containers:
```bash
# Force stop all Docker processes
sudo systemctl stop docker
sudo systemctl start docker
# Then retry cleanup
sudo docker system prune -af --volumes
```
### "Cannot remove container" error
```bash
# Find and kill process
sudo docker ps -a | grep oliver
sudo docker rm -f <container_id>
# If still stuck, restart Docker
sudo systemctl restart docker
```
### Check what's using disk space
```bash
# Largest Docker images
sudo docker images --format "table {{.Repository}}\t{{.Tag}}\t{{.Size}}" | sort -k 3 -h
# Disk usage by container
sudo docker ps -s
# Build cache size
sudo docker builder du
```
## 📝 Notes
- The `deploy.sh` script now includes automatic cleanup
- Old images are removed automatically during deployment
- Build cache is preserved for faster builds (24 hour window)
- Database and uploads are preserved unless explicitly deleted
- Frontend files in `/var/www/html/` are backed up to `/tmp/` during deployment

# Production Deployment Guide
## Server: Ubuntu + Apache
Production deployment на https://ai-sandbox.oliver.solutions/solventum-image-metadata/
## Prerequisites
### 1. Install System Dependencies
```bash
# Update system
sudo apt update && sudo apt upgrade -y
# Install Docker
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker $USER
# Install Docker Compose
sudo apt install docker-compose-plugin
# Install Node.js 18+
curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt install -y nodejs
# Verify versions
docker --version
docker compose version
node --version
npm --version
```
### 2. Configure Apache
```bash
# Enable required modules
sudo a2enmod proxy proxy_http headers rewrite ssl
# Copy Apache config
sudo cp /opt/solventum-image-metadata/apache-config.conf \
/etc/apache2/sites-available/solventum-image-metadata.conf
# Enable site
sudo a2ensite solventum-image-metadata
# Test config
sudo apache2ctl configtest
# Reload Apache
sudo systemctl reload apache2
```
### 3. Setup SSL (Let's Encrypt)
```bash
# Install Certbot
sudo apt install certbot python3-certbot-apache
# Get certificate
sudo certbot --apache -d ai-sandbox.oliver.solutions
# Auto-renewal
sudo systemctl enable certbot.timer
```
## Initial Deployment
### 1. Clone Repository
```bash
# Clone to /opt
cd /opt
sudo git clone <repository-url> solventum-image-metadata
cd solventum-image-metadata
```
### 2. Configure Environment
```bash
# Copy environment template
sudo cp .env.fastapi.example .env
# Edit configuration
sudo nano .env
```
**Required variables:**
```env
SECRET_KEY=<generate-with-python-secrets>
OPENAI_API_KEY=sk-...
AZURE_CLIENT_ID=9079054c-9620-4757-a256-23413042f1ef
AZURE_TENANT_ID=e519c2e6-bc6d-4fdf-8d9c-923c2f002385
AZURE_REDIRECT_URI=https://ai-sandbox.oliver.solutions/solventum-image-metadata/api/auth/microsoft/callback
```
**Generate SECRET_KEY:**
```bash
python3 -c "import secrets; print(secrets.token_hex(32))"
```
### 3. Create Required Directories
```bash
# Create data directories
sudo mkdir -p /opt/solventum-image-metadata/backend/{data,uploads,output/templates}
sudo mkdir -p /var/www/html/solventum-image-metadata
# Set permissions
sudo chown -R www-data:www-data /var/www/html/solventum-image-metadata
sudo chown -R $USER:$USER /opt/solventum-image-metadata/backend
```
### 4. Initial Deploy
```bash
cd /opt/solventum-image-metadata
sudo ./deploy.sh
```
## Updates / Re-deployment
```bash
# 1. Pull latest code (as normal user with git access)
cd /opt/solventum-image-metadata
git pull origin main
# 2. Run deployment script (as root)
sudo ./deploy.sh
```
The script is **idempotent** - safe to run multiple times.
## What the Deploy Script Does
1. ✅ Pre-flight checks (Docker, Node, permissions)
2. ✅ Validates environment variables
3. ✅ Builds Docker containers (with cache)
4. ✅ Stops old containers gracefully
5. ✅ Starts new containers (Redis + Backend)
6. ✅ Waits for Redis to be ready
7. ✅ Initializes database (first run only)
8. ✅ Installs frontend dependencies (npm ci)
9. ✅ Builds frontend (Vite production build)
10. ✅ Backs up existing frontend files
11. ✅ Deploys new frontend to /var/www/html/
12. ✅ Sets correct permissions (www-data)
13. ✅ Health checks (backend + Redis)
14. ✅ Cleanup old Docker images
## Verification
### 1. Check Services
```bash
# Docker containers
docker ps
# Backend logs
docker logs oliver-backend
# Redis logs
docker logs oliver-redis
```
### 2. Test Endpoints
```bash
# Backend health
curl http://localhost:8000/health
# API docs
curl http://localhost:8000/docs
# Frontend (through Apache)
curl https://ai-sandbox.oliver.solutions/solventum-image-metadata/
```
### 3. Test Full Flow
1. Open https://ai-sandbox.oliver.solutions/solventum-image-metadata/
2. Click "Login with Microsoft" (should redirect to Azure AD)
3. After SSO, should redirect back to dashboard
4. Upload a test file
5. Edit metadata
6. Download file
7. Verify metadata: `exiftool downloaded_file.pdf`
## Troubleshooting
### Backend not starting
```bash
# Check backend logs
docker logs oliver-backend --tail 100
# Check if port 8000 is already in use
sudo lsof -i :8000
# Restart backend
docker restart oliver-backend
```
### Redis connection error
```bash
# Check Redis
docker exec oliver-redis redis-cli ping
# Should return: PONG
# Check Redis logs
docker logs oliver-redis
# Restart Redis
docker restart oliver-redis
```
### Frontend 404 errors
```bash
# Check Apache config
sudo apache2ctl configtest
# Check file permissions
ls -la /var/www/html/solventum-image-metadata/
# Should be owned by www-data
sudo chown -R www-data:www-data /var/www/html/solventum-image-metadata/
# Check Apache error log
sudo tail -f /var/log/apache2/solventum-image-metadata-error.log
```
### API proxy errors
```bash
# Check if proxy modules enabled
apache2ctl -M | grep proxy
# Should see:
# proxy_module (shared)
# proxy_http_module (shared)
# Enable if missing
sudo a2enmod proxy proxy_http
# Restart Apache
sudo systemctl restart apache2
```
### SSO redirect loop
```bash
# Verify REDIRECT_URI in .env matches Apache config
grep AZURE_REDIRECT_URI /opt/solventum-image-metadata/.env
# Should be:
# AZURE_REDIRECT_URI=https://ai-sandbox.oliver.solutions/solventum-image-metadata/api/auth/microsoft/callback
# Check Azure AD app registration
# Redirect URI must match exactly (including /api/ prefix)
```
### Database locked
```bash
# Check if multiple backends running
docker ps | grep oliver-backend
# Stop all and restart
docker stop oliver-backend
docker start oliver-backend
```
## Rollback
If deployment fails and you need to rollback:
```bash
# 1. Stop new containers
docker-compose -f docker-compose.fastapi.yml down
# 2. Restore frontend from backup
sudo rm -rf /var/www/html/solventum-image-metadata/*
sudo cp -r /tmp/oliver-metadata-backup-TIMESTAMP/* /var/www/html/solventum-image-metadata/
# 3. Start old Flask app (if available)
docker-compose -f docker-compose.yml up -d
# 4. Check logs
docker logs oliver-metadata-tool
```
## Maintenance
### Regular Tasks
**Daily:**
- Monitor disk space: `df -h`
- Check Docker logs: `docker logs oliver-backend --tail 100`
**Weekly:**
- Cleanup old uploads: Files older than 7 days auto-deleted
- Check Redis memory: `docker exec oliver-redis redis-cli info memory`
**Monthly:**
- Update system packages: `sudo apt update && sudo apt upgrade`
- Renew SSL certificate (auto with certbot)
- Review logs for errors
### Backup Strategy
**Database:**
```bash
# Backup SQLite database
sudo cp /opt/solventum-image-metadata/backend/data/oliver_metadata.db \
/opt/backups/oliver_metadata_$(date +%Y%m%d).db
# Automated daily backup (crontab)
0 2 * * * cp /opt/solventum-image-metadata/backend/data/oliver_metadata.db /opt/backups/oliver_metadata_$(date +\%Y\%m\%d).db
```
**Uploads:**
```bash
# Backup uploads directory
sudo tar -czf /opt/backups/uploads_$(date +%Y%m%d).tar.gz \
/opt/solventum-image-metadata/backend/uploads/
```
**Redis (if critical data):**
```bash
# Redis snapshot (runs automatically with AOF enabled)
docker exec oliver-redis redis-cli BGSAVE
# Copy RDB file
docker cp oliver-redis:/data/dump.rdb /opt/backups/redis_$(date +%Y%m%d).rdb
```
## Monitoring
### Health Checks
```bash
# Backend
curl http://localhost:8000/health
# Redis
docker exec oliver-redis redis-cli ping
# Frontend
curl https://ai-sandbox.oliver.solutions/solventum-image-metadata/
```
### Logs
```bash
# Backend logs
docker logs oliver-backend -f
# Redis logs
docker logs oliver-redis -f
# Apache logs
sudo tail -f /var/log/apache2/solventum-image-metadata-access.log
sudo tail -f /var/log/apache2/solventum-image-metadata-error.log
```
### Performance
```bash
# Docker stats
docker stats oliver-backend oliver-redis
# Disk usage
du -sh /opt/solventum-image-metadata/backend/uploads/
# Redis memory
docker exec oliver-redis redis-cli info memory | grep used_memory_human
```

# Production Deployment Guide
Quick guide for deploying Oliver Metadata Tool v4.0 to Ubuntu server.
## 📋 Prerequisites
1. **Server Setup:**
- Ubuntu 20.04+ server
- Docker & Docker Compose installed
- Node.js 18+ & npm installed
- Apache/Nginx configured as reverse proxy
2. **Required Files:**
- `.env` file in project root with production values
- Apache/Nginx config for reverse proxy
3. **Repository Location:**
- Clone to: `/opt/solventum-image-metadata/`
- Frontend serves from: `/var/www/html/solventum-image-metadata/`
## 🚀 Quick Deployment
### First-Time Setup
```bash
# 1. Clone repository
cd /opt
sudo git clone <repository-url> solventum-image-metadata
cd solventum-image-metadata
# 2. Create .env file
sudo cp .env.production .env
sudo nano .env # Edit with production values
# 3. Configure frontend volume in docker-compose
sudo nano docker-compose.fastapi.yml
# Comment out line 69: - ./frontend/dist:/app/frontend/dist:ro
# 4. Run deployment
sudo ./deploy.sh
```
### Subsequent Updates
```bash
# Just run the deploy script - it handles everything!
cd /opt/solventum-image-metadata
sudo ./deploy.sh
```
The script automatically:
- ✅ Pulls latest code from git
- ✅ Cleans old Docker images
- ✅ Builds new containers
- ✅ Initializes database (first run only)
- ✅ Builds React frontend
- ✅ Deploys frontend to `/var/www/html/`
- ✅ Runs health checks
## 🧹 Clean Deployment (Remove Old Builds)
If you need to completely clean up before deploying:
```bash
cd /opt/solventum-image-metadata
# Option 1: Quick cleanup (recommended)
sudo docker-compose -f docker-compose.fastapi.yml down
sudo docker images | grep -E "oliver|solventum" | awk '{print $3}' | xargs -r sudo docker rmi -f
sudo docker system prune -f
# Option 2: Nuclear cleanup (see CLEANUP-COMMANDS.md)
# Use only if you want to delete everything including database
```
Then run `sudo ./deploy.sh`
## ⚙️ Configuration Files
### `.env` File (Production)
Required environment variables:
```bash
# OpenAI (required for AI features)
OPENAI_API_KEY=sk-proj-...

# Backup database
sudo cp backend/data/oliver_metadata.db backend/data/oliver_metadata.db.backup-$(date +%Y%m%d)
```
## 🚨 Troubleshooting
### Deployment fails with "Git pull failed"
```bash
cd /opt/solventum-image-metadata
sudo git status
sudo git stash # If uncommitted changes
sudo git pull origin main
sudo ./deploy.sh
```
### Backend health check fails
```bash
# Check logs
sudo docker-compose -f docker-compose.fastapi.yml logs backend
# Common issues:
# 1. OPENAI_API_KEY not set
# 2. Redis not running
# 3. Port 5001 already in use
```
### Frontend not loading
```bash
# Check files exist
ls -lh /var/www/html/solventum-image-metadata/
# Check permissions
sudo chown -R www-data:www-data /var/www/html/solventum-image-metadata/
sudo chmod -R 755 /var/www/html/solventum-image-metadata/
# Check Apache config
sudo apache2ctl -t
sudo systemctl reload apache2
```
### "Docker build failed"
```bash
# Clean Docker completely
sudo docker system prune -af --volumes
sudo systemctl restart docker
sudo ./deploy.sh
```
## 📊 Monitoring
### Check disk space
```bash
# Docker disk usage
sudo docker system df
# Project disk usage
du -sh /opt/solventum-image-metadata
du -sh /var/www/html/solventum-image-metadata
```
### Check logs
```bash
# Backend logs (last 100 lines)
cd /opt/solventum-image-metadata
sudo docker-compose -f docker-compose.fastapi.yml logs --tail=100 backend
# Follow logs in real-time
sudo docker-compose -f docker-compose.fastapi.yml logs -f
```
## 🔒 Security Notes
1. **Never commit .env files** with secrets to git
2. **Use strong SECRET_KEY** in production
3. **Backup database regularly** before updates
4. **Use HTTPS** for production (configure in Apache/Nginx)
5. **Review CORS settings** in backend/app/main.py if needed
## 📞 Support
For issues:
1. Check logs: `docker-compose logs`
2. Review [CLEANUP-COMMANDS.md](CLEANUP-COMMANDS.md) for cleanup options

# 6. Edit .env
nano ../.env
# 7. Run backend
python -m app.main
# 8. Access API
open http://localhost:8000/docs
```
## 📝 Configuration
### Required Environment Variables
```env
# OpenAI API key (required for AI metadata generation)
OPENAI_API_KEY=sk-...
# Secret key for JWT tokens (generate new one!)
SECRET_KEY=$(python -c "import secrets; print(secrets.token_hex(32))")
# Redis URL
REDIS_URL=redis://localhost:6379/0
```
### Optional Environment Variables
```env
# Database (default: SQLite)

AZURE_CLIENT_ID=...
AZURE_CLIENT_SECRET=...
AZURE_TENANT_ID=...
# Frontend URL for CORS
FRONTEND_URL=http://localhost:3000
```
## 🧪 Testing the API
### 1. Create a Test User
```bash
curl -X POST http://localhost:8000/auth/register \
-H "Content-Type: application/json" \
-d '{"username": "testuser", "password": "testpass"}'
```
### 2. Login and Get Tokens
```bash
curl -X POST http://localhost:8000/auth/login \
-H "Content-Type: application/json" \
-d '{"username": "testuser", "password": "testpass"}'
```
Response:
```json
{
"access_token": "eyJ...",
"refresh_token": "eyJ...",
"token_type": "bearer",
"expires_in": 1800,
"user": {...}
}
```
### 3. Upload Files
```bash
# Save access token
TOKEN="your-access-token-here"
# Upload file with AI metadata
curl -X POST http://localhost:8000/files/upload \
-H "Authorization: Bearer $TOKEN" \
-F "files=@test.pdf" \
-F "metadata_source=ai"
```
### 4. Update Metadata
```bash
curl -X PUT http://localhost:8000/metadata/FILE_ID \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/json" \
-d '{
"session_id": "SESSION_ID",
"file_index": 0,
"metadata": {
"title": "Updated Title",
"subject": "Updated Subject",
"keywords": "test, metadata"
}
}'
```
### 5. Download File
```bash
curl -X GET http://localhost:8000/files/FILE_ID/download \
-H "Authorization: Bearer $TOKEN" \
--output downloaded_file.pdf
```
## 📚 Interactive API Documentation
FastAPI provides automatic interactive API docs:
- **Swagger UI**: http://localhost:8000/docs
- **ReDoc**: http://localhost:8000/redoc
You can test all endpoints directly in the browser!
## 🔧 Architecture
### Session Management (CRITICAL FIX)
**Before (Flask):**
- In-memory dict: `sessions = {}`
- Lost on restart ❌
**After (FastAPI):**
- Redis with TTL
- Persistent across restarts ✅
- User sessions: 7 days
- File sessions: 1 hour
- Auto-cleanup
### Authentication Flow
1. Login → JWT access token (30 min) + refresh token (7 days)
2. Refresh token stored in Redis
3. Frontend sends: `Authorization: Bearer <access_token>`
4. Token expired? → Use refresh token to get new access token
5. Logout → Delete session from Redis
### File Processing Flow
1. Upload files → Save to `uploads/{user_id}/{YYYYMMDD}/`
2. Create session in Redis with file info
3. Generate metadata (AI/Excel/Import/Manual/Template)
4. User reviews/edits metadata
5. Update file with metadata
6. Download processed file
7. Cleanup (automatic after 7 days)
## 🐳 Docker Services
### Running Services
```bash
# Start all services
docker-compose -f docker-compose.fastapi.yml up -d
# View logs
docker-compose -f docker-compose.fastapi.yml logs -f
# Stop services
docker-compose -f docker-compose.fastapi.yml down
# Rebuild backend
docker-compose -f docker-compose.fastapi.yml build backend
docker-compose -f docker-compose.fastapi.yml up -d backend
```
### Service URLs
- **Backend API**: http://localhost:8000
- **API Docs**: http://localhost:8000/docs
- **Redis**: localhost:6379
- **PostgreSQL**: localhost:5432 (optional)
## 🗄️ Database
### SQLite (Default)
Location: `backend/data/oliver_metadata.db`
**Pros:**
- Simple, no setup
- Good for single server
- Easy migration from Flask
**Cons:**
- No concurrent writes
- Not for multi-server deployment
### PostgreSQL (Optional)
**Pros:**
- Better performance
- Concurrent connections
- Multi-server support
**To enable:**
```yaml
# docker-compose.fastapi.yml
environment:
DATABASE_URL: postgresql+asyncpg://oliver:${DB_PASSWORD}@postgres:5432/oliver_metadata
```
## 📦 What's Reused from Flask
These components are **100% unchanged**:
- `backend/app/processors/extractors/` - All file extractors
- `backend/app/processors/updaters/` - All file updaters
- `backend/app/processors/metadata_analyzer.py` - AI generation
- `backend/app/processors/excel_metadata_lookup.py` - Excel lookup
- `backend/app/processors/template_manager.py` - Templates
- `backend/app/processors/config.py` - Configuration
**Zero modifications needed** - they work perfectly with FastAPI!
## 🔒 Security
### Production Checklist
- [ ] Change `SECRET_KEY` to random 64-char string
- [ ] Enable HTTPS (set `REDIRECT_URI` to https://)
- [ ] Restrict CORS origins in `main.py`
- [ ] Set `DEBUG=false` in production
- [ ] Use PostgreSQL instead of SQLite for multi-server
- [ ] Enable Redis password: `redis://user:password@host:6379/0`
- [ ] Regular backups of database and uploads
- [ ] Monitor Redis memory usage
## 🐛 Troubleshooting
### Redis Connection Error
```bash
# Check if Redis is running
redis-cli ping
# Should return: PONG
# If not running:
redis-server
```
### Database Lock Error
```bash
# SQLite only - check if another process is using DB
lsof backend/data/oliver_metadata.db
# If stuck, delete and restart:
rm backend/data/oliver_metadata.db
docker-compose -f docker-compose.fastapi.yml restart backend
```
### Import Errors
```bash
# Check if all dependencies installed
cd backend
pip list | grep fastapi
pip list | grep redis
# If missing:
pip install -r requirements.txt
```
### File Upload 413 Error
```bash
# Increase max file size in main.py or nginx.conf
# Default: 500MB (configured in processors/config.py)
```
## 📈 Monitoring
### Check Redis Sessions
```bash
# Connect to Redis
redis-cli
# List all session keys
KEYS *session*
# Get session data
GET file_session:SESSION_ID
# Check memory usage
INFO memory
```
### Check Storage
```bash
# Get storage stats
curl http://localhost:8000/files/stats \
-H "Authorization: Bearer $TOKEN"
```
### Check Logs
```bash
# Docker logs
docker-compose -f docker-compose.fastapi.yml logs -f backend
# Or if running locally
# Logs printed to console
```
## 🚧 What's Next (Frontend)
To complete the migration:
1. Create React frontend (see plan in `.claude/plans/`)
2. Implement file upload UI with drag-drop
3. Metadata editor components
4. Template management UI
5. Import/Excel mapping modals
Backend is **100% ready** for frontend integration!

## Troubleshooting
## 🔍 Troubleshooting
### Common Issues
**ExifTool not found:**
**1. Backend health check fails**
```bash
# Verify installation
exiftool -ver
# Check logs
docker-compose -f docker-compose.fastapi.yml logs backend
# macOS: Reinstall with Homebrew
brew reinstall exiftool
# Linux: Reinstall with apt
sudo apt-get install --reinstall libimage-exiftool-perl
# Common causes:
# - OPENAI_API_KEY not set
# - Redis not running
# - Port 5001 already in use
```
**Database locked error:**
**2. Frontend not loading**
```bash
# Stop all instances
lsof -ti:5001 | xargs kill -9
# Check files exist
ls -lh /var/www/html/solventum-image-metadata/
# Restart application
python web_app.py
# Check permissions
sudo chown -R www-data:www-data /var/www/html/solventum-image-metadata/
```
**OpenAI API errors:**
- Check API key in `.env` file
- Verify API key is valid at https://platform.openai.com/api-keys
- Check token usage limits on OpenAI dashboard
**3. Git pull fails during deployment**
```bash
# First deployment: This is normal!
# The script will continue with existing code
**Import failed - column not found:**
- Use the mapping modal to manually select columns
- Check that your file has headers in the first row
- Verify file encoding is UTF-8
# For updates: Set up git credentials
cd /opt/solventum-image-metadata
sudo git remote set-url origin https://username:token@bitbucket.org/...
```
**4. Docker build fails**
```bash
# Clean Docker and retry
sudo docker system prune -af
sudo ./deploy.sh
```

# AI Metadata Generation Integration - Summary
## Overview
Successfully integrated AI metadata generation into the FastAPI backend. The MetadataAnalyzer is now fully integrated with the file upload endpoint, allowing users to generate metadata using OpenAI's GPT models.
## Changes Made
### 1. Fixed MetadataService AI Integration
**File:** `backend/app/services/metadata_service.py`
#### Changes:
- **Fixed `ai_analyzer` property** (lines 63-71):
- Changed return type from `MetadataAnalyzer` to `Optional[MetadataAnalyzer]`
- Added try-except to gracefully handle missing OPENAI_API_KEY
- Returns `None` instead of raising ValueError when API key not configured
- **Updated `_generate_ai_metadata` method** (lines 172-220):
- Added check for AI analyzer availability at the start
- Returns helpful error message if OPENAI_API_KEY not configured
- Fixed `analyze_content` call to pass `FileType` enum instead of string
- Improved error handling and fallback metadata
### 2. Fixed Environment Variable Configuration
**File:** `backend/app/processors/config.py`
#### Changes:
- **Updated `AI_MODEL` configuration** (line 42):
- Changed from: `AI_MODEL = os.getenv('AI_MODEL', 'gpt-4o-mini')`
- Changed to: `AI_MODEL = os.getenv('OPENAI_MODEL') or os.getenv('AI_MODEL', 'gpt-4o-mini')`
- Now supports both `OPENAI_MODEL` and `AI_MODEL` environment variables
- Maintains backward compatibility with existing configs
### 3. Created Integration Test
**File:** `backend/test_ai_integration.py` (new)
Created comprehensive test script that verifies:
- All imports work correctly
- MetadataService initializes properly
- AI analyzer is available (if OPENAI_API_KEY configured)
- AI metadata generation works end-to-end
Run with: `python3 backend/test_ai_integration.py`
## How AI Integration Works
### Flow:
1. **User uploads file** → POST `/api/files/upload` with `metadata_source="ai"`
2. **FileService** saves the uploaded file
3. **MetadataService.generate_metadata()** is called with `source="ai"`
4. **Routes to `_generate_ai_metadata()`**:
- Detects file type (PDF, Image, Office, Video)
- Gets appropriate extractor for the file type
- Extracts content from the file
- Calls `MetadataAnalyzer.analyze_content()` with:
- `content`: Extracted text from file
- `filename`: Original filename
- `file_type`: FileType enum (PDF, IMAGE, etc.)
5. **MetadataAnalyzer**:
- Truncates content to fit token limits
- Creates specialized prompt based on file type
- Calls OpenAI API with retry logic
- Parses JSON response into metadata dict
- Returns: `{title, subject, keywords, _tokens_used, _confidence}`
6. **Response** sent back to frontend with suggested metadata
### Error Handling:
- **No OPENAI_API_KEY**: Returns error message in metadata
- **Insufficient content**: Returns filename-based fallback metadata
- **API failures**: Automatic retry with exponential backoff (3 attempts)
- **Parsing errors**: Falls back to text-based parsing
## Configuration
### Required Environment Variables:
```env
# Required
OPENAI_API_KEY=sk-...
# Optional (with defaults)
OPENAI_MODEL=gpt-4o-mini # or AI_MODEL
MAX_TOKENS=500
TEMPERATURE=0.5
MAX_TEXT_LENGTH=4000
API_TIMEOUT=30
API_MAX_RETRIES=3
API_RETRY_DELAY=1.0
```
## Testing
### 1. Syntax Check:
```bash
cd backend
python3 -m py_compile app/services/metadata_service.py
python3 -m py_compile app/api/files.py
```
✅ Both files compile without syntax errors
### 2. Integration Test:
```bash
cd backend
pip install -r requirements.txt
python3 test_ai_integration.py
```
### 3. Manual API Test:
```bash
# Start backend
cd backend
uvicorn app.main:app --reload --port 8000
# Upload file with AI generation
curl -X POST http://localhost:8000/api/files/upload \
-H "Authorization: Bearer <token>" \
-F "files=@sample.pdf" \
-F "metadata_source=ai"
```
## Files Modified
1. **backend/app/services/metadata_service.py**
- Lines 63-71: ai_analyzer property
- Lines 172-220: _generate_ai_metadata method
2. **backend/app/processors/config.py**
- Line 42: AI_MODEL configuration
3. **backend/test_ai_integration.py** (NEW)
- Complete integration test suite
## Dependencies
All required dependencies are already in `backend/requirements.txt`:
- `openai>=1.0.0` - OpenAI API client
- `tiktoken>=0.5.0` - Token counting
- `tenacity>=8.2.0` - Retry logic with exponential backoff
## Notes
### Unicode Support:
- MetadataAnalyzer fully supports Unicode (Chinese, Japanese, Korean)
- Uses custom `safe_filename()` - NEVER use `secure_filename()`
### Token Tracking:
- Token usage logged to audit_log table
- Returned in metadata as `_tokens_used`
- Useful for cost tracking and monitoring
### Model Support:
- Automatically detects model capabilities
- GPT-5/GPT-4o models: use `max_completion_tokens`
- GPT-3.5 models: use `max_tokens` + `temperature`
- Invalid models fall back to `gpt-4o-mini`
### Content Truncation:
- Automatically truncates content to 4000 tokens
- Uses tiktoken for accurate token counting
- Character-based fallback if tiktoken unavailable
## Next Steps
1. Install dependencies: `pip install -r backend/requirements.txt`
2. Configure OPENAI_API_KEY in backend/.env
3. Run integration test: `python3 backend/test_ai_integration.py`
4. Test via API with actual files
5. Monitor token usage in audit logs
## Verification Checklist

# Apache Configuration Migration Guide
## ⚠️ Important Changes for FastAPI
Your current Apache config uses **Flask on port 5001**. For FastAPI, you need to change:
**Note:** Using **port 5001** (same as Flask) for Azure AD compatibility
### Current (Flask):
```apache
ProxyPass /solventum-image-metadata/ http://localhost:5001/
ProxyPassReverse /solventum-image-metadata/ http://localhost:5001/
```
### New (FastAPI):
```apache
# Frontend - static files (React build)
Alias /solventum-image-metadata /var/www/html/solventum-image-metadata
<Directory /var/www/html/solventum-image-metadata>
Options -Indexes +FollowSymLinks
AllowOverride All
Require all granted
# React Router (SPA) - rewrite to index.html
RewriteEngine On
RewriteBase /solventum-image-metadata
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/solventum-image-metadata/api/
RewriteRule ^ /solventum-image-metadata/index.html [L]
</Directory>
# Backend API - proxy to FastAPI
ProxyPreserveHost On
ProxyTimeout 600
<Location /solventum-image-metadata/api>
ProxyPass http://localhost:5001
ProxyPassReverse http://localhost:5001
RequestHeader set X-Forwarded-Proto "https"
RequestHeader set X-Forwarded-For "%{REMOTE_ADDR}s"
</Location>
```
## Key Changes:
1. **Port unchanged**: 5001 (same port as Flask for Azure AD compatibility)
2. **Frontend**: Separate static files (not proxied)
3. **API prefix**: `/solventum-image-metadata/api/` → Backend
4. **SPA routing**: RewriteRule for React Router
## Update on Server:
```bash
# 1. Edit Apache config
sudo nano /etc/apache2/sites-available/solventum-image-metadata.conf
# 2. Replace the ProxyPass lines with the new config above
# 3. Enable required modules
sudo a2enmod rewrite headers alias
# 4. Test config
sudo apache2ctl configtest
# 5. Reload Apache
sudo systemctl reload apache2
```
## Update .env on Server:
```bash
# Edit /opt/solventum-image-metadata/.env
sudo nano /opt/solventum-image-metadata/.env
# Change REDIRECT_URI:
REDIRECT_URI=https://ai-sandbox.oliver.solutions/solventum-image-metadata/api/auth/microsoft/callback
# ^^^^ ADD /api/
```
## Verify:
```bash
# Backend health (direct)
curl http://localhost:5001/health
# Frontend (through Apache)
curl https://ai-sandbox.oliver.solutions/solventum-image-metadata/
# API (through Apache)
curl https://ai-sandbox.oliver.solutions/solventum-image-metadata/api/health
```
## Complete Apache VirtualHost Example:
```apache

# Apache Configuration - Simple Version
## Для ai-sandbox.oliver.solutions
### Вариант 1: Только Backend Proxy (проще, но медленнее)
Backend FastAPI будет serve и static files и API:
```apache
# Oliver Metadata Tool - Backend only
ProxyPass /solventum-image-metadata/ http://localhost:5001/
ProxyPassReverse /solventum-image-metadata/ http://localhost:5001/
ProxyTimeout 600
```
**Требует:** Backend должен serve статические файлы React (добавить StaticFiles в FastAPI)
---
### Вариант 2: Разделение Frontend/Backend (быстрее, рекомендую)
Frontend - static files, Backend - только API:
```apache
# Oliver Metadata Tool - Frontend static files
Alias /solventum-image-metadata /var/www/html/solventum-image-metadata
<Directory /var/www/html/solventum-image-metadata>
Options -Indexes +FollowSymLinks
AllowOverride All
Require all granted
# React Router support
RewriteEngine On
RewriteBase /solventum-image-metadata
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !^/solventum-image-metadata/api/
RewriteRule ^ /solventum-image-metadata/index.html [L]
</Directory>
# Backend API - FastAPI
ProxyPass /solventum-image-metadata/api/ http://localhost:5001/
ProxyPassReverse /solventum-image-metadata/api/ http://localhost:5001/
ProxyTimeout 600
```
**Преимущества:**
- Apache serve статику быстрее чем FastAPI
- Backend занимается только API логикой
- Лучше кеширование static assets
---
## Что использовать?
**Рекомендую Вариант 2** - разделение Frontend/Backend.
Просто добавьте эти строки в существующую конфигурацию Apache.
## После изменения Apache:
```bash
# Проверить конфиг
sudo apache2ctl configtest
# Reload Apache
sudo systemctl reload apache2
```
## Также обновите .env на сервере:
```bash
sudo nano /opt/solventum-image-metadata/.env
# Добавьте /api/ в REDIRECT_URI:
REDIRECT_URI=https://ai-sandbox.oliver.solutions/solventum-image-metadata/api/auth/microsoft/callback
```
## Проверка:
```bash
# Frontend (static files через Apache)
curl https://ai-sandbox.oliver.solutions/solventum-image-metadata/
# Backend API (proxy через Apache)
curl https://ai-sandbox.oliver.solutions/solventum-image-metadata/api/health
```
