OpenEnv Compatibility

Docker-only execution

All commands run inside Docker containers. Use the provided scripts.

W8-RL implements OpenEnv as a FastAPI server deployed inside Ray Serve. This preserves the OpenEnv HTTP contract while still using Ray for scale-out.

Key points​

  • Server runs in ray-head (Ray Serve)
  • Client runs in ray-worker
  • Single-session per server instance (OpenEnv client compatibility)
  • Scale-out is achieved by running multiple server instances

Endpoints​

  • POST /reset
  • POST /step (HTTP)
  • GET /state
  • POST /close
  • WebSocket /step (streaming)

Run OpenEnv path​

Run the command below from the repo root in Docker:

./scripts/run_design2code_openenv.sh design2code_0000 --use-openhands

openenv.yaml​

The environment manifest is located at:

w8_rl/openenv/openenv.yaml

It follows the OpenEnv echo_env schema and points to server.app:app.
