GetComputeAuthToken

Requests an authentication token from Amazon GameLift for a compute resource in an Amazon GameLift Anywhere fleet or container fleet. Game servers that are running on the compute use this token to communicate with the Amazon GameLift service, such as when calling the Amazon GameLift server SDK action InitSDK(). Authentication tokens are valid for a limited time span, so you need to request a fresh token before the current token expires.

Use this operation based on the fleet compute type:

For EC2 fleets, auth token retrieval and refresh is handled automatically. All game servers that are running on all fleet instances have access to a valid auth token.
For ANYWHERE and CONTAINER fleets, if you're using the Amazon GameLift Agent, auth token retrieval and refresh is handled automatically for any container or Anywhere compute where the Agent is running. If you're not using the Agent, create a mechanism to retrieve and refresh auth tokens for computes that are running game server processes.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Note

In the following list, the required parameters are described first.

ComputeName

The name of the compute resource you are requesting the authentication token for. For an Anywhere fleet compute, use the registered compute name. For an EC2 fleet instance, use the instance ID. For a container fleet, use the compute name (for example, a123b456c789012d3e4567f8a901b23c/1a234b56-7cd8-9e0f-a1b2-c34d567ef8a9) or the compute ARN.

Type: String

Length Constraints: Maximum length of 1024.

Pattern: ^[a-zA-Z0-9\-]+(\/[a-zA-Z0-9\-]+)?$|^arn:.*:compute\/[a-zA-Z0-9\-]+(\/[a-zA-Z0-9\-]+)?

Required: Yes

FleetId

A unique identifier for the fleet that the compute is registered to.

Type: String

Pattern: ^fleet-\S+|^arn:.*:fleet\/fleet-\S+

Required: Yes

Response Elements

If the action is successful, the service sends back an HTTP 200 response.

The following data is returned in JSON format by the service.

Pattern: ^[a-zA-Z0-9\-]+(\/[a-zA-Z0-9\-]+)?$|^arn:.*:compute\/[a-zA-Z0-9\-]+(\/[a-zA-Z0-9\-]+)?

ExpirationTimestamp

The amount of time until the authentication token is no longer valid.

Type: Timestamp

FleetArn

The Amazon Resource Name (ARN) that is assigned to a Amazon GameLift fleet resource and uniquely identifies it. ARNs are unique across all Regions. Format is arn:aws:gamelift:<region>::fleet/fleet-a1234567-b8c9-0d1e-2fa3-b45c6d7e8912.
