Amazon GameLift Servers adds DescribeContainerGroupPortMappings API for container fleets

Hello Amazon GameLift Servers developers,

We are excited to announce the launch of the new DescribeContainerGroupPortMappings API for Amazon GameLift Servers container fleets. This new API makes it easy to retrieve port mappings for containers running on your container fleet, returning the mapping between the ports your containers listen on internally and the corresponding ports exposed on the host instance to which external clients can connect.

Previously, port mapping information for the game server container was only available through the CreateGameSession response. The new DescribeContainerGroupPortMappings API extends that capability so you can now retrieve port mappings for all containers in a game server container group, as well as per-instance containers that run alongside game server groups. This means you no longer need to remotely access your compute to discover how your container ports are mapped, reducing operational overhead and simplifying your debugging and networking workflows.

This API is available today in all Amazon GameLift Servers supported regions (except AWS China). To learn more, see the following resources:

We welcome your feedback on this new capability and would love to hear how it's improving your Amazon GameLift Servers experience.

Best regards, The Amazon GameLift Servers Team
