Note: You are viewing the documentation for an older major version of the AWS CLI (version 1).

AWS CLI version 2, the latest major version of AWS CLI, is now stable and recommended for general use. To view this page for the AWS CLI version 2, click here. For more information see the AWS CLI version 2 installation instructions and migration guide.

update-runtime-configuration

Description

Updates the current runtime configuration for the specified fleet, which tells GameLift how to launch server processes on all instances in the fleet. You can update a fleet's runtime configuration at any time after the fleet is created; it does not need to be in ACTIVE status.

To update runtime configuration, specify the fleet ID and provide a RuntimeConfiguration with an updated set of server process configurations.

If successful, the fleet's runtime configuration settings are updated. Each instance in the fleet regularly checks for and retrieves updated runtime configurations. Instances immediately begin complying with the new configuration by launching new server processes or not replacing existing processes when they shut down. Updating a fleet's runtime configuration never affects existing server processes.

Synopsis

  update-runtime-configuration
--fleet-id <value>
--runtime-configuration <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--fleet-id (string)

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

--runtime-configuration (structure)

Instructions for launching server processes on each instance in the fleet. Server processes run either a custom game build executable or a Realtime Servers script. The runtime configuration lists the types of server processes to run on an instance, how to launch them, and the number of processes to run concurrently.

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 .

Shorthand Syntax:

ServerProcesses=[{LaunchPath=string,Parameters=string,ConcurrentExecutions=integer},{LaunchPath=string,Parameters=string,ConcurrentExecutions=integer}],MaxConcurrentGameSessionActivations=integer,GameSessionActivationTimeoutSeconds=integer

JSON Syntax:

{
  "ServerProcesses": [
    {
      "LaunchPath": "string",
      "Parameters": "string",
      "ConcurrentExecutions": integer
    }
    ...
  ],
  "MaxConcurrentGameSessionActivations": integer,
  "GameSessionActivationTimeoutSeconds": integer
}

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See 'aws help' for descriptions of global parameters.

Output

RuntimeConfiguration -> (structure)

The runtime configuration currently in use by all instances in the fleet. If the update was successful, all property changes are shown.

ServerProcesses -> (list)

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