feat: Implement pluggable multi-provider sandbox architecture (#12820)
## Summary Implement a flexible sandbox provider system supporting both self-managed (Docker) and SaaS (Aliyun Code Interpreter) backends for secure code execution in agent workflows. **Key Changes:** - ✅ Aliyun Code Interpreter provider using official `agentrun-sdk>=0.0.16` - ✅ Self-managed provider with gVisor (runsc) security - ✅ Arguments parameter support for dynamic code execution - ✅ Database-only configuration (removed fallback logic) - ✅ Configuration scripts for quick setup Issue #12479 ## Features ### 🔌 Provider Abstraction Layer **1. Self-Managed Provider** (`agent/sandbox/providers/self_managed.py`) - Wraps existing executor_manager HTTP API - gVisor (runsc) for secure container isolation - Configurable pool size, timeout, retry logic - Languages: Python, Node.js, JavaScript - ⚠️ **Requires**: gVisor installation, Docker, base images **2. Aliyun Code Interpreter** (`agent/sandbox/providers/aliyun_codeinterpreter.py`) - SaaS integration using official agentrun-sdk - Serverless microVM execution with auto-authentication - Hard timeout: 30 seconds max - Credentials: `AGENTRUN_ACCESS_KEY_ID`, `AGENTRUN_ACCESS_KEY_SECRET`, `AGENTRUN_ACCOUNT_ID`, `AGENTRUN_REGION` - Automatically wraps code to call `main()` function **3. E2B Provider** (`agent/sandbox/providers/e2b.py`) - Placeholder for future integration ### ⚙️ Configuration System - `conf/system_settings.json`: Default provider = `aliyun_codeinterpreter` - `agent/sandbox/client.py`: Enforces database-only configuration - Admin UI: `/admin/sandbox-settings` - Configuration validation via `validate_config()` method - Health checks for all providers ### 🎯 Key Capabilities **Arguments Parameter Support:** All providers support passing arguments to `main()` function: ```python # User code def main(name: str, count: int) -> dict: return {"message": f"Hello {name}!" * count} # Executed with: arguments={"name": "World", "count": 3} # Result: {"message": "Hello World!Hello World!Hello World!"} ``` **Self-Describing Providers:** Each provider implements `get_config_schema()` returning form configuration for Admin UI **Error Handling:** Structured `ExecutionResult` with stdout, stderr, exit_code, execution_time ## Configuration Scripts Two scripts for quick Aliyun sandbox setup: **Shell Script (requires jq):** ```bash source scripts/configure_aliyun_sandbox.sh ``` **Python Script (interactive):** ```bash python3 scripts/configure_aliyun_sandbox.py ``` ## Testing ```bash # Unit tests uv run pytest agent/sandbox/tests/test_providers.py -v # Aliyun provider tests uv run pytest agent/sandbox/tests/test_aliyun_codeinterpreter.py -v # Integration tests (requires credentials) uv run pytest agent/sandbox/tests/test_aliyun_codeinterpreter_integration.py -v # Quick SDK validation python3 agent/sandbox/tests/verify_sdk.py ``` **Test Coverage:** - 30 unit tests for provider abstraction - Provider-specific tests for Aliyun - Integration tests with real API - Security tests for executor_manager ## Documentation - `docs/develop/sandbox_spec.md` - Complete architecture specification - `agent/sandbox/tests/MIGRATION_GUIDE.md` - Migration from legacy sandbox - `agent/sandbox/tests/QUICKSTART.md` - Quick start guide - `agent/sandbox/tests/README.md` - Testing documentation ## Breaking Changes ⚠️ **Migration Required:** 1. **Directory Move**: `sandbox/` → `agent/sandbox/` - Update imports: `from sandbox.` → `from agent.sandbox.` 2. **Mandatory Configuration**: - SystemSettings must have `sandbox.provider_type` configured - Removed fallback default values - Configuration must exist in database (from `conf/system_settings.json`) 3. **Aliyun Credentials**: - Requires `AGENTRUN_*` environment variables (not `ALIYUN_*`) - `AGENTRUN_ACCOUNT_ID` is now required (Aliyun primary account ID) 4. **Self-Managed Provider**: - gVisor (runsc) must be installed for security - Install: `go install gvisor.dev/gvisor/runsc@latest` ## Database Schema Changes ```python # SystemSettings.value: CharField → TextField api/db/db_models.py: Changed for unlimited config length # SystemSettingsService.get_by_name(): Fixed query precision api/db/services/system_settings_service.py: startswith → exact match ``` ## Files Changed ### Backend (Python) - `agent/sandbox/providers/base.py` - SandboxProvider ABC interface - `agent/sandbox/providers/manager.py` - ProviderManager - `agent/sandbox/providers/self_managed.py` - Self-managed provider - `agent/sandbox/providers/aliyun_codeinterpreter.py` - Aliyun provider - `agent/sandbox/providers/e2b.py` - E2B provider (placeholder) - `agent/sandbox/client.py` - Unified client (enforces DB-only config) - `agent/tools/code_exec.py` - Updated to use provider system - `admin/server/services.py` - SandboxMgr with registry & validation - `admin/server/routes.py` - 5 sandbox API endpoints - `conf/system_settings.json` - Default: aliyun_codeinterpreter - `api/db/db_models.py` - TextField for SystemSettings.value - `api/db/services/system_settings_service.py` - Exact match query ### Frontend (TypeScript/React) - `web/src/pages/admin/sandbox-settings.tsx` - Settings UI - `web/src/services/admin-service.ts` - Sandbox service functions - `web/src/services/admin.service.d.ts` - Type definitions - `web/src/utils/api.ts` - Sandbox API endpoints ### Documentation - `docs/develop/sandbox_spec.md` - Architecture spec - `agent/sandbox/tests/MIGRATION_GUIDE.md` - Migration guide - `agent/sandbox/tests/QUICKSTART.md` - Quick start - `agent/sandbox/tests/README.md` - Testing guide ### Configuration Scripts - `scripts/configure_aliyun_sandbox.sh` - Shell script (jq) - `scripts/configure_aliyun_sandbox.py` - Python script ### Tests - `agent/sandbox/tests/test_providers.py` - 30 unit tests - `agent/sandbox/tests/test_aliyun_codeinterpreter.py` - Provider tests - `agent/sandbox/tests/test_aliyun_codeinterpreter_integration.py` - Integration tests - `agent/sandbox/tests/verify_sdk.py` - SDK validation ## Architecture ``` Admin UI → Admin API → SandboxMgr → ProviderManager → [SelfManaged|Aliyun|E2B] ↓ SystemSettings ``` ## Usage ### 1. Configure Provider **Via Admin UI:** 1. Navigate to `/admin/sandbox-settings` 2. Select provider (Aliyun Code Interpreter / Self-Managed) 3. Fill in configuration 4. Click "Test Connection" to verify 5. Click "Save" to apply **Via Configuration Scripts:** ```bash # Aliyun provider export AGENTRUN_ACCESS_KEY_ID="xxx" export AGENTRUN_ACCESS_KEY_SECRET="yyy" export AGENTRUN_ACCOUNT_ID="zzz" export AGENTRUN_REGION="cn-shanghai" source scripts/configure_aliyun_sandbox.sh ``` ### 2. Restart Service ```bash cd docker docker compose restart ragflow-server ``` ### 3. Execute Code in Agent ```python from agent.sandbox.client import execute_code result = execute_code( code='def main(name: str) -> dict: return {"message": f"Hello {name}!"}', language="python", timeout=30, arguments={"name": "World"} ) print(result.stdout) # {"message": "Hello World!"} ``` ## Troubleshooting ### "Container pool is busy" (Self-Managed) - **Cause**: Pool exhausted (default: 1 container in `.env`) - **Fix**: Increase `SANDBOX_EXECUTOR_MANAGER_POOL_SIZE` to 5+ ### "Sandbox provider type not configured" - **Cause**: Database missing configuration - **Fix**: Run config script or set via Admin UI ### "gVisor not found" - **Cause**: runsc not installed - **Fix**: `go install gvisor.dev/gvisor/runsc@latest && sudo cp ~/go/bin/runsc /usr/local/bin/` ### Aliyun authentication errors - **Cause**: Wrong environment variable names - **Fix**: Use `AGENTRUN_*` prefix (not `ALIYUN_*`) ## Checklist - [x] All tests passing (30 unit tests + integration tests) - [x] Documentation updated (spec, migration guide, quickstart) - [x] Type definitions added (TypeScript) - [x] Admin UI implemented - [x] Configuration validation - [x] Health checks implemented - [x] Error handling with structured results - [x] Breaking changes documented - [x] Configuration scripts created - [x] gVisor requirements documented Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com> --------- Co-authored-by: Claude Sonnet 4.5 <noreply@anthropic.com>
