* Adds Kubernetes sandbox provisioner support * Improves Docker dev setup by standardizing host paths Replaces hardcoded host paths with a configurable root directory, making the development environment more portable and easier to use across different machines. Automatically sets the root path if not already defined, reducing manual setup steps.

🦌 DeerFlow - v2
Originated from Open Source, give back to Open Source.
A LangGraph-based AI agent backend with sandbox execution capabilities.
Quick Start
Configuration
-
Copy the example config:
cp config.example.yaml config.yaml cp .env.example .env -
Edit
config.yamland set your API keys in.envand preferred sandbox mode.
Sandbox Configuration
DeerFlow supports multiple sandbox execution modes. Configure your preferred mode in config.yaml:
Local Execution (runs sandbox code directly on the host machine):
sandbox:
use: src.sandbox.local:LocalSandboxProvider # Local execution
Docker Execution (runs sandbox code in isolated Docker containers):
sandbox:
use: src.community.aio_sandbox:AioSandboxProvider # Docker-based sandbox
Docker Execution with Kubernetes (runs sandbox code in Kubernetes pods via provisioner service):
This mode runs each sandbox in an isolated Kubernetes Pod on your host machine's cluster. Requires Docker Desktop K8s, OrbStack, or similar local K8s setup.
sandbox:
use: src.community.aio_sandbox:AioSandboxProvider
provisioner_url: http://provisioner:8002
See Provisioner Setup Guide for detailed configuration, prerequisites, and troubleshooting.
Running the Application
Option 1: Docker (Recommended)
The fastest way to get started with a consistent environment:
-
Initialize and start:
make docker-init # Pull sandbox image (Only once or when image updates) make docker-start # Start all services and watch for code changes -
Access: http://localhost:2026
See CONTRIBUTING.md for detailed Docker development guide.
Option 2: Local Development
If you prefer running services locally:
-
Check prerequisites:
make check # Verifies Node.js 22+, pnpm, uv, nginx -
(Optional) Pre-pull sandbox image:
# Recommended if using Docker/Container-based sandbox make setup-sandbox -
Start services:
make dev -
Access: http://localhost:2026
See CONTRIBUTING.md for detailed local development guide.
