How to interact with stockfish running in docker

Build the container stockfish:15:

make build

Create a file called stockfish with the following contents (one is included in this repo):

#!/bin/sh
nc localhost 23249

Give it executable permissions with:

chmod +x stockfish

Now you can run the following to start stockfish:

make start

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:

./stockfish
uci
isready
ucinewgame
position startpos moves e2e4 e7e5 g1f3 g8f6
go depth 20
quit

For more information about stockfish, see the stockfish github page.

import chess
import chess.engine

stockfish = chess.engine.SimpleEngine.popen_uci("./stockfish")

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

stockfish.quit()
