Codex/OpenAI CLI Example ​

Use the official @openai/codex npm package to call OpenAI/Codex-like models in OpenSandbox.

Start OpenSandbox server [local] ​

Pre-pull the code-interpreter image (includes Node.js):

shell
docker pull sandbox-registry.cn-zhangjiakou.cr.aliyuncs.com/opensandbox/code-interpreter:v1.0.1

# use docker hub
# docker pull opensandbox/code-interpreter:v1.0.1

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

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

Create and Access the Codex Sandbox ​

shell
# Install OpenSandbox package
uv pip install opensandbox

# Run the example (requires SANDBOX_DOMAIN / SANDBOX_API_KEY / OPENAI_API_KEY)
uv run python examples/codex-cli/main.py

The script installs the Codex CLI (npm install -g @openai/codex@latest) at runtime (Node.js is already in the code-interpreter image), then executes a simple request codex exec "Compute 1+1 and return JSON with keys result and reasoning." --skip-git-repo-check. Auth is passed via OPENAI_API_KEY; you can override endpoint/model with OPENAI_BASE_URL / OPENAI_MODEL.

Environment Variables ​

  • SANDBOX_DOMAIN: Sandbox service address (default: localhost:8080)
  • SANDBOX_API_KEY: API key if your server requires authentication (optional for local)
  • SANDBOX_IMAGE: Sandbox image to use (default: sandbox-registry.cn-zhangjiakou.cr.aliyuncs.com/opensandbox/code-interpreter:v1.0.1)
  • OPENAI_API_KEY: Your OpenAI API key (required)
  • OPENAI_BASE_URL: OpenAI API endpoint (default: https://api.openai.com/v1)
  • OPENAI_MODEL: Model to use (default: gpt-4o-mini)
