describe_fleet_attributes

GameLift.Client.describe_fleet_attributes(**kwargs)

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

Retrieves core fleet-wide properties for fleets in an Amazon Web Services Region. Properties include the computing hardware and deployment configuration for instances in the fleet.

You can use this operation in the following ways:

• To get attributes for specific fleets, provide a list of fleet IDs or fleet ARNs.

• To get attributes for all fleets, do not provide a fleet identifier.

When requesting attributes for multiple fleets, use the pagination parameters to retrieve results as a set of sequential pages.

If successful, a FleetAttributes object is returned for each fleet requested, unless the fleet identifier is not found.

Note

Some API operations limit the number of fleet IDs that allowed in one request. If a request exceeds this limit, the request fails and the error message contains the maximum allowed number.

Response Structure

• (dict) –

  • FleetAttributes (list) –

    A collection of objects containing attribute metadata for each requested fleet ID. Attribute objects are returned only for fleets that currently exist.

    • (dict) –

      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.

      Returned by: DescribeFleetAttributes

      • FleetId (string) –

        A unique identifier for the fleet.

      • FleetArn (string) –

        The Amazon Resource Name ( ARN) that is assigned to a Amazon GameLift fleet resource and uniquely identifies it. ARNs are unique across all Regions.

        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.

        The policy is evaluated when a player tries to create a new game session. On receiving a CreateGameSession request, Amazon GameLift checks that the player (identified by CreatorId) has created fewer than game session limit in the specified time period.

        • NewGameSessionsPerCreator (integer) –

          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.

          The policy is evaluated when a player tries to create a new game session. On receiving a CreateGameSession request, Amazon GameLift checks that the player (identified by CreatorId) has created fewer than game session limit in the specified time period.

        A unique identifier for an IAM role with access permissions to other Amazon Web Services 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 Amazon Web Services resources that you own or have access to. For more information about using the role with your game server builds, see Communicate with other Amazon Web Services resources from your fleets. This attribute is used with fleets where ComputeType is “EC2” or “Container”.

      • CertificateConfiguration (dict) –

        Determines whether a TLS/SSL certificate is generated for a fleet. This feature must be enabled when creating the fleet. All instances in a fleet share the same certificate.

        • CertificateType (string) –

          Indicates whether a TLS/SSL certificate is generated for a fleet.

          Valid values include:

          • GENERATED - Generate a TLS/SSL certificate for this fleet.

          • DISABLED - (default) Do not generate a TLS/SSL certificate for this fleet.

These attributes are included for fleets with compute type CONTAINER only. This attribute is used with fleets where ComputeType is “Container”.

        • Cost (string) –

          The cost to run your fleet per hour. Amazon GameLift uses the provided cost of your fleet to balance usage in queues. For more information about queues, see Setting up queues in the Amazon GameLift Developer Guide.

      • InstanceRoleCredentialsProvider (string) –

        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 Amazon Web Services 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 Amazon Web Services resources from your fleets. This attribute is used with fleets where ComputeType is “EC2” or “Container”.

      • ContainerGroupsAttributes (dict) –

A fleet’s connection port range can’t be changed, but you can control access to connection ports by updating a fleet’s EC2InboundPermissions with UpdateFleetPortSettings.

          • FromPort (integer) –

            Starting value for the port range.
