Google ADK + OpenSandbox Example

Integrate Google Agent Development Kit (ADK) with OpenSandbox. The ADK agent drives tool calls that execute inside a sandbox.

Start OpenSandbox server [local]

Pre-pull the code-interpreter image (includes Python):

docker pull sandbox-registry.cn-zhangjiakou.cr.aliyuncs.com/opensandbox/code-interpreter:v1.1.0

# use docker hub
# docker pull opensandbox/code-interpreter:v1.1.0

Start the local OpenSandbox server, logs will be visible in the terminal:

uv pip install opensandbox-server
opensandbox-server init-config ~/.sandbox.toml --example docker
opensandbox-server

Run the example

# Install OpenSandbox + Google ADK deps
uv pip install opensandbox google-adk

# Run the example (requires SANDBOX_DOMAIN / SANDBOX_API_KEY / GOOGLE_API_KEY)
uv run python examples/google-adk/main.py

The script uses ADK to create an agent with OpenSandbox tools (write_file, read_file, run_in_sandbox). It runs a few prompts, prints tool events, and cleans up the sandbox.

Environment Variables

Variable	Default	Description
SANDBOX_DOMAIN	localhost:8080	Sandbox service address
SANDBOX_API_KEY	(optional for local)	API key if your server requires authentication
