describe_fleet_attributes#

GameLift.Client.describe_fleet_attributes(**kwargs)#

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) –

        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).

        • 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.

See Migrate to Amazon GameLift server SDK version 5.

        • ResourceCreationLimitPolicy (dict) –

          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.

            The time span used in evaluating the resource creation limit policy.

        • MetricGroups (list) –

          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”.

          • (string) –

        • StoppedActions (list) –

          A list of fleet activity that has been suspended using StopFleetActions. This includes fleet auto-scaling. This attribute is used with fleets where ComputeType is “EC2”.

          • (string) –

        • InstanceRoleArn (string) –

          A unique identifier for an IAM role that manages access to your Amazon Web Services services. With an instance role ARN set, any application that runs on an instance in this fleet can assume the role, including install scripts, server processes, and daemons (background processes). Create a role or look up a role’s ARN by using the IAM dashboard in the Amazon Web Services Management Console. Learn more about using on-box credentials for your game servers at Access external resources from a game server. This attribute is used with fleets where ComputeType is “EC2”.

        • 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.

          • 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”.
