How to interact with stockfish running in docker

Create a file called stockfish with the following contents:

#!/bin/sh
nc localhost 23249

Give it executable permissions with:

chmod +x stockfish

Now you can run the following to start stockfish:

docker run -d --rm --name stockfish -p 23249:23249 -p 23250:23250 -v $(pwd):/stockfish:ro -w /stockfish stockfish

This will start a stockfish instance that will listen on port 23249 for commands.

You can now run ./stockfish to interact with the stockfish instance.

./stockfish
uci
isready
quit

More examples of stockfish engine interaction are:

    result = stockfish.play(board, chess.engine.Limit(time=0.1))
    board.push(result.move)
    print(board, "\n")

stockfish.quit()
