Freezout Poker Docker image

Run the Web server

To run the web server that serves the WASM client we need to know the WebSocket URL the client uses to connect to the game server and pass it to the container. Use wss://host:port if the server is using TLS encryption or ws://host:port if the server is not using TLS, note that when TLS is disabled communication between client and the game server is encrypted using Noise protocol.

For example if the game server is using TLS on port 9871 at example.com:

$ docker run -p 80:80 -p 443:443 vincev/freezeout:latest  web wss://example.com:9871
Starting nginx server with web clients connecting to  wss://example.com:9871.

then use a browser to connect to the web server URL and load the client.

Run the Poker server

To run the poker server use the poker command:

$ docker run -p 9871:9871 vincev/freezeout:latest poker
Starting Poker server
[2025-05-22T11:32:54.511Z INFO ] Listening on 0.0.0.0:9871 with 10 tables and 3 seats per table
[2025-05-22T11:32:54.511Z INFO ] Loading keypair /usr/share/freezeout/server.phrase
[2025-05-22T11:32:54.512Z INFO ] Loading database /usr/share/freezeout/game.db
[2025-05-22T11:32:54.513Z WARN ] TLS not enabled, using NOISE encryption

Note that we need to map the server listening port to allow clients to connect to it. To use a different port we can use the --port option:

$ docker run -p 9888:9888 vincev/freezeout:latest poker --port 9888
Starting Poker server
[2025-05-22T11:34:49.378Z INFO ] Listening on 0.0.0.0:9888 with 10 tables and 3 seats per table[2025-05-22T11:34:49.378Z INFO ] Loading keypair /usr/share/freezeout/server.phrase

[2025-05-22T11:34:49.380Z WARN ] TLS not enabled, using NOISE encryption

By default the poker server runs with 10 tables and 3 seats per table, we can override these values using the --tables and --seats options:

$ docker run -p 9871:9871 vincev/freezeout:latest poker --tables 5 --seats 6
Starting Poker server
[2025-05-22T11:37:22.698Z INFO ] Listening on 0.0.0.0:9871 with 5 tables and 6 seats per table
[2025-05-22T11:37:22.698Z INFO ] Loading keypair /usr/share/freezeout/server.phrase

[2025-05-22T11:37:22.699Z WARN ] TLS not enabled, using NOISE encryption

The server saves player chips into a local database, to persist the data across containers runs we can use a volume and map the server data folder with the -v option:

$ docker run -p 9871:9871 -v freezeout:/usr/share/freezeout vincev/freezeout:latest poker
Starting Poker server
[2025-05-22T11:37:22.698Z INFO ] Listening on 0.0.0.0:9871 with 10 tables and 3 seats per table
[2025-05-22T11:37:22.698Z INFO ] Loading keypair /usr/share/freezeout/server.phrase

[2025-05-22T11:37:22.699Z WARN ] TLS not enabled, using NOISE encryption

To enale TSS you need specify certificates to use:

$ docker run -p 9871:9871 vincev/freezeout:latest poker --key-path privkey.pem --chain-path fullchain.pem
Starting Poker server
