🐳 Docker Deployment

Development Environment

docker-compose up openmemory-dev ollama-dev
- SQLite database - Local Ollama embeddings - $0 cost - Perfect for development/testing

Production Environment

docker-compose up -d openmemory-prod postgres ollama-prod
- PostgreSQL database - Cloud Ollama or local embeddings - $15-20/month cost - Production-ready with backups

Health Check

curl http://localhost:8080/health

🔐 Security

API Key Management

# Development (default)
OPENMEMORY_API_KEY=dev-api-key-12345

# Production (change required!)
OPENMEMORY_API_KEY=your-secure-production-key

Database Security

  • PostgreSQL password required in production
  • SQLite file-based for development
  • Network isolation in Docker

Environment Variables

All sensitive data in .env (not in code)

🚨 Troubleshooting

OpenMemory not connecting

# Check if backend is healthy
curl http://localhost:8080/health

# Check logs
docker logs openmemory-dev

Ollama not running

# Check container
docker ps | grep ollama

# Pull missing model
docker exec ollama-dev ollama pull nomic-embed-text

Memory not being saved

  • Check logs in slack_bot.py
  • Verify OPENMEMORY_URL environment variable
  • Ensure database is writable
  • Check OpenMemory backend logs

Tests failing

# Install test dependencies
pip install pytest pytest-asyncio

# Run with verbose output
pytest tests/ -vv -s

📖 API Reference

OpenMemoryService

Initialize

service = OpenMemoryService(
    openmemory_url="http://localhost:8080",
    openmemory_api_key="api-key"
)
await service.initialize()

Add Memory

await service.client.add_memory(
    content="Memory content",
    user_id="user-123",
    sector="episodic",
    tags=["tag1", "tag2"],
    metadata={"key": "value"}
)

Search Memories

results = await service.search_memory(
    query="search query",
    user_id="user-123",
    k=5,
    sectors=["episodic", "semantic"]
)

Get Summary

summary = await service.get_summary("user-123")

🤝 Contributing

To extend memory sectors:

  1. Update openmemory_service.py
  2. Add sector handling in add_session_to_memory()
  3. Add tests to tests/test_openmemory_service.py
  4. Update documentation

To add new OpenMemory features:

  1. Add HTTP method to client.py
