FleetAttributes

This operation has been expanded to use with the Amazon GameLift containers feature, which is currently in public preview.

Describes an Amazon GameLift fleet of game hosting resources. Attributes differ based on the fleet's compute type, as follows:

EC2 fleet attributes identify a Build resource (for fleets with customer game server builds) or a Script resource (for Realtime Servers fleets).
Container fleets have ContainerGroupsAttributes, which identify the fleet's ContainerGroupDefinition resources.
Amazon GameLift Anywhere fleets have an abbreviated set of attributes, because most fleet configurations are set directly on the fleet's computes. Attributes include fleet identifiers and descriptive properties, creation/termination time, and fleet status.

FleetId

A unique identifier for the fleet.

Type: String

Valid Values: ON_DEMAND | SPOT

Required: No

InstanceRoleArn

A unique identifier for an IAM role with access permissions to other AWS services. Any application that runs on an instance in the fleet--including install scripts, server processes, and other processes--can use these permissions to interact with AWS resources that you own or have access to. For more information about using the role with your game server builds, see Communicate with other AWS resources from your fleets. This attribute is used with fleets where ComputeType is "EC2" or "Container".

Type: String

Length Constraints: Minimum length of 1.

Required: No

InstanceRoleCredentialsProvider

Indicates that fleet instances maintain a shared credentials file for the IAM role defined in InstanceRoleArn. Shared credentials allow applications that are deployed with the game server executable to communicate with other AWS resources. This property is used only when the game server is integrated with the server SDK version 5.x. For more information about using shared credentials, see Communicate with other AWS resources from your fleets. This attribute is used with fleets where ComputeType is "EC2" or "Container".

Type: String

Valid Values: SHARED_CREDENTIAL_FILE

Required: No

InstanceType

The Amazon EC2 instance type that the fleet uses. Instance type determines the computing resources of each instance in the fleet, including CPU, memory, storage, and networking capacity. See Amazon Elastic Compute Cloud Instance Types for detailed descriptions. This attribute is used with fleets where ComputeType is "EC2" or "Container".

Type: String

Required: No

LogPaths

This parameter is no longer used. Game session log paths are now defined using the Amazon GameLift server API ProcessReady() logParameters. See more information in the Server API Reference.

Type: Array of strings

Length Constraints: Minimum length of 1. Maximum length of 1024.

Required: No

MetricGroups

Name of a metric group that metrics for this fleet are added to. In Amazon CloudWatch, you can view aggregated metrics for fleets that are in a metric group. A fleet can be included in only one metric group at a time. This attribute is used with fleets where ComputeType is "EC2" or "Container".

Type: Array of strings

Array Members: Maximum number of 1 item.

ResourceCreationLimitPolicy

A policy that puts limits on the number of game sessions that a player can create within a specified span of time. With this policy, you can control players' ability to consume available resources.
