[ aws . gamelift ]



Retrieves information about a fleet’s instances, including instance IDs. Use this operation to get details on all instances in the fleet or get details on one specific instance.

To get a specific instance, specify fleet ID and instance ID. To get all instances in a fleet, specify a fleet ID only. Use the pagination parameters to retrieve results as a set of sequential pages. If successful, an Instance object is returned for each result.

See ‘aws help’ for descriptions of global parameters.

describe-instances is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: Instances


--fleet-id <value>
[--instance-id <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]


--fleet-id (string)

A unique identifier for a fleet to retrieve instance information for. You can use either the fleet ID or ARN value.

--instance-id (string)

A unique identifier for an instance to retrieve. Specify an instance ID or leave blank to retrieve all instances in the fleet.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


Instances -> (list)

A collection of objects containing properties for each instance returned.


Properties that describe an instance of a virtual computing resource that hosts one or more game servers. A fleet may contain zero or more instances.

FleetId -> (string)

A unique identifier for a fleet that the instance is in.

InstanceId -> (string)

A unique identifier for an instance.

IpAddress -> (string)

IP address that is assigned to the instance.

DnsName -> (string)

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 instance.

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 -> (timestamp)

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

NextToken -> (string)

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.
