The proxy was using instance.port which is a dynamically allocated
host port (e.g., 10001). But containers communicate on the Docker
network using their internal ports (8443 for code-server, 8888 for
jupyter). This caused connection failures when opening instances.
- Add default_port field to ToolType model (null for terminal-only tools)
- Create migration 0010 for default_port column
- Update seed data: code-server=8443, jupyter=8888, opencode=null
- Update proxy to use tool type's default_port instead of instance.port
- Update frontend ToolType interface to include default_port
Fixes: Opening instances now routes to correct internal container port
Add support for tool categories, interface types, and per-tool configuration.
Backend:
- Add category and interfaces fields to ToolType model
- Create ToolConfig model for storing tool-specific settings
- Add tool_configs API endpoints (CRUD)
- Update built-in tool types with categories and interfaces:
- code-server: editor, [web]
- jupyter-notebook: notebook, [web]
- opencode: ai-assistant, [terminal]
- Update instance API to include tool type interfaces
- Create Alembic migrations 0008 and 0009
Frontend:
- Update ToolType and Session interfaces with new fields
- Conditionally show Open/Terminal buttons based on tool interfaces
- Add API client for tool configs
OpenSpec: tool-config-management change created and implemented.
Add API proxy endpoint so users can access running tool instances
through the backend API instead of internal Docker network.
Backend:
- Add container_name field to ToolInstance model
- Create /instances/{id}/proxy/{path:path} endpoint with ownership checks
- Proxy HTTP requests to containers via docker network using container names
- Support all HTTP methods (GET, POST, PUT, DELETE, PATCH, HEAD, OPTIONS)
- Store proxy URL in instance.url instead of localhost
- Add Alembic migration 0007 for container_name column
- Add get_container_name() utility to docker.py
Frontend:
- Update Open button to use full proxy URL (API_BASE_URL + instance.url)
Closes instance-proxy OpenSpec change.
Backend:
- Create ToolInstance model with status tracking
- Add Alembic migration for tool_instances table
- Create Docker service for compose template rendering and container execution
- Add CRUD API endpoints for tool instances
- Add lifecycle endpoints (start/stop/restart)
- Add user sessions endpoint for navigation
- Register routers in main.py
Frontend:
- Create SessionsProvider with React context
- Create sessions API client
- Update AppShell with sessions section in navigation
- Add session status indicators and polling
- Add CSS for session navigation
Quality gates: typecheck ✓, lint ✓, build ✓
Add if_not_exists=True to CREATE TABLE operations in migrations
0003 and 0004. This prevents DuplicateTableError when migrations
are re-run on databases where tables were partially created.
Add migration version check before running alembic upgrade to prevent
multiple uvicorn workers from running migrations simultaneously.
- Check current vs head revision before running migrations
- Skip migration if already at latest version
- Log current and head revision for debugging
- Add theme support with dark/light/system modes
- Add useTheme hook for applying user config theme
- Update router to use SettingsPage
- Update app-shell to apply theme on load
- Add CSS variables for dark theme
- Fix mypy errors in user_config.py
- Quality gates pass: ruff, mypy, typecheck, lint, build
- Add docker-compose.yml with postgres, redis, api, and web services
- Add multi-stage Dockerfile for API (Python 3.11)
- Add multi-stage Dockerfile for web (Node.js 20 + nginx)
- Add Makefile with common development commands
- Add .env.example with all required environment variables
- Add placeholder pyproject.toml and package.json for builds
- Configure health checks for all services
- Setup persistent volumes for postgres, redis, and repos
- Run services as non-root users
