DescribeRuntimeConfiguration

Retrieves a fleet's runtime configuration settings. The runtime configuration determines which server processes run, and how, on computes in the fleet. For managed EC2 fleets, the runtime configuration describes server processes that run on each fleet instance. can update a fleet's runtime configuration at any time using UpdateRuntimeConfiguration.

To get the current runtime configuration for a fleet, provide the fleet ID.

If successful, a RuntimeConfiguration object is returned for the requested fleet. If the requested fleet has been deleted, the result set is empty.

Examples

Request the runtime configuration for a fleet

This example retrieves the current runtime configuration for a specified fleet. As shown, the requested fleet is configured to run four concurrent processes of the game server executable, one with debug mode turned on. The property MaxConcurrentGameSessionActivations is set to the default value, which places no limit on concurrent activations.

HTTP requests are authenticated using an Amazon Signature Version 4 signature in the Authorization header field.
