Resolve chat service build failure caused by missing output directory: **Root Cause:** - output/ directory is in .gitignore and not included in Docker build context - COPY output/ /app/output/ failed with "not found" error - PYTHONPATH still had undefined $PYTHONPATH variable **Solution:** - Remove COPY output/ line (directory created later with mkdir) - Fix PYTHONPATH: /app/src:$PYTHONPATH → /app/src - output/ directory already created at line 51: mkdir -p /app/output **Errors Fixed:** - ERROR: "/output": not found - WARNING: Usage of undefined variable '$PYTHONPATH' Successfully tested Docker build. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
Docker Development Environment
This directory contains Docker configurations for running the Datacenter Documentation System in development mode.
Prerequisites
- Docker Engine 20.10+
- Docker Compose V2
- At least 4GB RAM available for Docker
Quick Start
# Start all services
cd deploy/docker
docker-compose -f docker-compose.dev.yml up -d
# View logs
docker-compose -f docker-compose.dev.yml logs -f
# Stop all services
docker-compose -f docker-compose.dev.yml down
Environment Variables
Create a .env file in the project root with:
ANTHROPIC_API_KEY=your_api_key_here
MCP_SERVER_URL=http://localhost:8001
Services
Running Services
| Service | Port | Description | Status |
|---|---|---|---|
| API | 8000 | FastAPI documentation server | ✅ Healthy |
| MongoDB | 27017 | Database | ✅ Healthy |
| Redis | 6379 | Cache & message broker | ✅ Healthy |
| Frontend | 80 | React web interface | ⚠️ Running |
| Flower | 5555 | Celery monitoring | ✅ Running |
Not Implemented Yet
- Chat Service (port 8001) - WebSocket chat interface
- Worker Service - Celery background workers
These services are commented out in docker-compose.dev.yml and will be enabled when implemented.
Access Points
- API Documentation: http://localhost:8000/docs
- API Health: http://localhost:8000/health
- Frontend: http://localhost
- Flower (Celery Monitor): http://localhost:5555
- MongoDB:

Build Individual Services
# Rebuild a specific service
docker-compose -f docker-compose.dev.yml up --build -d api
# View logs for a specific service
docker-compose -f docker-compose.dev.yml logs -f api
Troubleshooting
API not starting
Check logs:
docker-compose -f docker-compose.dev.yml logs api
MongoDB connection issues
Ensure MongoDB is healthy:
docker-compose -f docker-compose.dev.yml ps mongodb
Clear volumes and restart
docker-compose -f docker-compose.dev.yml down -v
docker-compose -f docker-compose.dev.yml up --build -d
Development Workflow
- Code changes are mounted as volumes, so changes to
src/are reflected immediately - Restart services after dependency changes:
docker-compose -f docker-compose.dev.yml restart api - Rebuild after pyproject.toml changes:
docker-compose -f docker-compose.dev.yml up --build -d api

Notes
- Python version: 3.12
- Black formatter uses Python 3.12 target
- Services use Poetry for dependency management
- Frontend uses Vite for building
