Remove redundant log file creation for MCP services since output is
already captured by Docker logs. This simplifies deployment by removing
unnecessary volume mounts and file management.
Changes:
- Remove logs/ directory creation from Dockerfile
- Remove logs/ volume mount from docker-compose.yml
- Update start_mcp_services.py to send output to DEVNULL
- Update documentation to reflect changes (DOCKER.md, docs/DOCKER.md)
- Update .env.example to remove logs/ from volume description
Users can still view MCP service output via 'docker logs' or
'docker-compose logs -f'. Trading session logs in data/agent_data/
remain unchanged.
Root cause: Python adds script directory (not working directory)
to sys.path. Services in /app/agent_tools/ couldn't import from
/app/tools/ because sys.path[0] was /app/agent_tools.
Solution: Set PYTHONPATH=/app when starting services so /app is
always in the Python import path.
Fixes: ModuleNotFoundError: No module named 'tools' in price.log
Run MCP service manager from /app instead of /app/agent_tools
to ensure services can import from tools module.
Changes:
- entrypoint.sh: Run start_mcp_services.py from /app directory
- start_mcp_services.py: Use absolute paths for service scripts
- start_mcp_services.py: Set working directory to /app for services
Fixes ModuleNotFoundError: No module named 'tools' in price.log
