  • Discover co-located containers on the same instance
  • Availability and SDK support for container improvements
Features (2)
  • Customize Linux capabilities for game server containers

    Developers can now customize Linux capabilities for containers within their container group definitions in Amazon GameLift Servers. This offers finer control beyond Docker's defaults, allowing specialized capabilities like NET_RAW for custom networking or SYS_PTRACE for debugging.

  • Discover co-located containers on the same instance

    A new ListContainersNetworkInfo() server SDK action allows game servers to retrieve network information for all containers on the same instance. This includes container name, ID, local IP, and type, enabling automatic service discovery and communication with auxiliary services.

Notes (1)
  • Availability and SDK support for container improvements

    These enhancements are available through the GameLift console, AWS CLI, SDKs, and CloudFormation in all supported AWS regions except China. The ListContainersNetworkInfo() action is supported in server SDK 5.x for Go, C++, C#, and engine plugins.
