Execution Command

The execution command lets you override the default CMD of the Docker image. Most of the time, you don't need to change this — the image's default command is designed to start the game server correctly.

When to Use It

You might override the execution command if you need to:

• Run a custom startup script
• Pass specific flags to the game server binary
• Chain multiple commands at startup

How It Works

The execution command is passed as the Docker container's CMD when the container is created. If left empty, the image's default CMD is used.

Example

For a vanilla Minecraft server image, the default command might be:

java -Xmx1024M -jar server.jar nogui

You could override it to increase memory:

java -Xmx4096M -jar server.jar nogui

Configuration

Edit the execution command in the Settings view of your server. The command is stored as a list of arguments — COSY passes them directly to Docker without shell interpretation.
