describe-runtime-configuration

Description

Retrieves a fleet’s runtime configuration settings. The runtime configuration tells GameLift which server processes to run (and how) on each instance in the fleet.

To get the runtime configuration that is currently in forces 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.

Synopsis

  describe-runtime-configuration
--fleet-id <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options

--fleet-id (string)

A unique identifier for the fleet to get the runtime configuration for. You can use either the fleet ID or ARN value.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Examples

To request the runtime configuration for a fleet

The following describe-runtime-configuration example retrieves details about the current runtime configuration for a specified fleet.

aws gamelift describe-runtime-configuration \
    --fleet-id fleet-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111

Output:

{
    "RuntimeConfiguration": {
        "ServerProcesses": [
            {
                "LaunchPath": "C:\game\Bin64.Release.Dedicated\MegaFrogRace_Server.exe",
                "Parameters": "+gamelift_start_server",
                "ConcurrentExecutions": 3
            },
            {
                "LaunchPath": "C:\game\Bin64.Release.Dedicated\MegaFrogRace_Server.exe",
                "Parameters": "+gamelift_start_server +debug",
                "ConcurrentExecutions": 1
            }
        ],

        "GameSessionActivationTimeoutSeconds": 300
    }

Output

RuntimeConfiguration -> (structure)

Instructions that describe how server processes should be launched and maintained on each instance in the fleet.

ServerProcesses -> (list)

A collection of server process configurations that identify what server processes to run on each instance in a fleet.

(structure)

A set of instructions for launching server processes on each instance in a fleet. Server processes run either an executable in a custom game build or a Realtime Servers script. Server process configurations are part of a fleet’s RuntimeConfiguration .

LaunchPath -> (string)

The location of a game build executable or the Realtime script file that contains the Init() function. Game builds and Realtime scripts are installed on instances at the root:

• Windows (custom game builds only): C:\game . Example: “C:\game\MyGame\server.exe “

• Linux: /local/game . Examples: “/local/game/MyGame/server.exe ” or “/local/game/MyRealtimeScript.js “

Parameters -> (string)

An optional list of parameters to pass to the server executable or Realtime script on launch.

ConcurrentExecutions -> (integer)

The number of server processes using this configuration that run concurrently on each instance.

MaxConcurrentGameSessionActivations -> (integer)

The number of game sessions in status ACTIVATING to allow on an instance. This setting limits the instance resources that can be used for new game activations at any one time.

GameSessionActivationTimeoutSeconds -> (integer)

The maximum amount of time (in seconds) allowed to launch a new game session and have it report ready to host players. During this time, the game session is in status ACTIVATING . If the game session does not become active before the timeout, it is ended and the game session status is changed to TERMINATED .
