Docker

This folder has all the files required to create the docker containers for the hosted server. Instructions here can also be used to setup a local multiplayer server as well.

To start a local server bundled with three test players:

docker compose up --build

To run in detached mode:

docker compose up --build --detach

To stop the containers running in detached mode:

docker compose down

Local clients can specify the server as -s http://localhost

To start a hosted server on an example domain, say example.com:

SITE_ADDRESS=example.com docker compose up --build --detach

This is how the hosted server at https://box.servegame.com is started.

By default, there is no verbose logging and only errors from the server or client components get printed. To enable verbose logging, these can be passed through environment variables:

SERVER_PARAMS="-v" CLIENT_PARAMS="-v" SITE_ADDRESS="example.com" docker compose up --build

Here is how the output of that should look like:

Notes

• The Container-Optimized OS in GCP does not include docker compose
  • Thus, it is installed through the install-docker-compose-google-cos.sh script
• The Alpine image that is the base for the client container does not have a valid libc needed for the caia test players and hence libc.so.6 and ld-linux.so.2 are packaged in that image. See caia-linux.
• Server Dockerfile
• Client Dockerfile
• Overall docker-compose.yml
