GameLift / Client / describe_instances

describe_instances#

GameLift.Client.describe_instances(**kwargs)#

Retrieves information about the EC2 instances in an Amazon GameLift managed fleet, including instance ID, connection data, and status. You can use this operation with a multi-location fleet to get location-specific instance information. As an alternative, use the operations ListCompute and DescribeCompute to retrieve information for compute resources, including EC2 and Anywhere fleets.

You can call this operation in the following ways:

  • To get information on all instances in a fleet’s home Region, specify the fleet ID.

  • To get information on all instances in a fleet’s remote location, specify the fleet ID and location name.

  • To get information on a specific instance in a fleet, specify the fleet ID and instance ID.

Use the pagination parameters to retrieve results as a set of sequential pages.

If successful, this operation returns Instance objects for each requested instance, listed in no particular order. If you call this operation for an Anywhere fleet, you receive an InvalidRequestException.

Response Structure

  • (dict) –

    • Instances (list) –

      A collection of objects containing properties for each instance returned.

      • (dict) –

        Represents a virtual computing instance that runs game server processes and hosts game sessions. In Amazon GameLift, one or more instances make up a managed EC2 fleet.

        • FleetId (string) –

          A unique identifier for the fleet that the instance belongs to.

        • 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. Format is arn:aws:gamelift:<region>::fleet/fleet-a1234567-b8c9-0d1e-2fa3-b45c6d7e8912.

        • InstanceId (string) –

          A unique identifier for the instance.

        • IpAddress (string) –

          IP address that is assigned to the instance.

        • DnsName (string) –

          The DNS identifier assigned to the instance that is running the game session. Values have the following format:

          • TLS-enabled fleets: <unique identifier>.<region identifier>.amazongamelift.com.

          • Non-TLS-enabled fleets: ec2-<unique identifier>.compute.amazonaws.com. (See Amazon EC2 Instance IP Addressing.)

          When connecting to a game session that is running on a TLS-enabled fleet, you must use the DNS name, not the IP address.

        • OperatingSystem (string) –

          Operating system that is running on this EC2 instance.

          Note

          Amazon Linux 2 (AL2) will reach end of support on 6/30/2025. See more details in the Amazon Linux 2 FAQs. For game servers that are hosted on AL2 and use Amazon GameLift server SDK 4.x., first update the game server build to server SDK 5.x, and then deploy to AL2023 instances. See Migrate to Amazon GameLift server SDK version 5.

        • Type (string) –

          EC2 instance type that defines the computing resources of this instance.

        • Status (string) –

          Current status of the instance. Possible statuses include the following:

          • PENDING – The instance is in the process of being created and launching server processes as defined in the fleet’s run-time configuration.

          • ACTIVE – The instance has been successfully created and at least one server process has successfully launched and reported back to Amazon GameLift that it is ready to host a game session. The instance is now considered ready to host game sessions.

          • TERMINATING – The instance is in the process of shutting down. This may happen to reduce capacity during a scaling down event or to recycle resources in the event of a problem.

        • CreationTime (datetime) –

          A time stamp indicating when this data object was created. Format is a number expressed in Unix time as milliseconds (for example "1469498468.057").

        • Location (string) –

          The fleet location of the instance, expressed as an Amazon Web Services Region code, such as us-west-2.

    • NextToken (string) –

      A token that indicates where to resume retrieving results on the next call to this operation. If no token is returned, these results represent the end of the list.
