DockFish - Stockfish Server Docker Image

Server/Cloud-ready Stockfish Docker image based on slim Node Debian image including:

• Stockfish Engine
• A simple Node.js script to communicate with Stockfish Engine via UCI commands through WebSockets

This image is intented for people who want to setup their own Stockfish Server using own server or cloud instance.

Docker Hub prebuilt images are automatically updated on a daily basis.

You have to communicate with this server via WebSockets.
You can send 2 event types: auth:authenticate and uci:command.
You can receive 3 event types: auth:authenticated, auth:unauthenticated and uci:response.
All sent and received events look like that: { type: string } or { type: string, payload: string }.

Check the client example to understand how that works.

Example

You can check a very simple implementation example in examples/simple using this Docker image. You'll find a README.md there explaining how to it works and how to run it locally.

Docker Environment Variables

API_TOKEN

If you set the API_TOKEN, sent socket events will need to be authenticated using this token. Otherwise anybody can listen and emit to your server.

Undefined by default.

PORT

REQUIRED

This is the server exposed port to emit and listen socket events.

Docker Arguments

⚠️ The arguments can ONLY be used if you build your image DIRECTLY from the ./dockerfiles directory and not via the Docker Hub images that are prebuilt using the default values declared below.

ARCH

Sanity Check

Once you have deployed Dockfish either locally or remotely, you can check if the server is running by visiting the /check path.

You should normally see a plain text body stating: "Dockfish is up and running.".
