describe-game-server-instances

Description

This operation is used with the GameLift FleetIQ solution and game server groups.

Retrieves status information about the Amazon EC2 instances associated with a GameLift FleetIQ game server group. Use this operation to detect when instances are active or not available to host new game servers. If you are looking for instance configuration information, call DescribeGameServerGroup or access the corresponding Auto Scaling group properties.

To request status for all instances in the game server group, provide a game server group ID only. To request status for specific instances, provide the game server group ID and one or more instance IDs. Use the pagination parameters to retrieve results in sequential segments. If successful, a collection of GameServerInstance objects is returned.

This operation is not designed to be called with every game server claim request; this practice can cause you to exceed your API limit, which results in errors. Instead, as a best practice, cache the results and refresh your cache no more than once every 10 seconds.

describe-game-server-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: GameServerInstances

Options

--game-server-group-name (string)

A unique identifier for the game server group. Use either the GameServerGroup name or ARN value.

--instance-ids (list)

The Amazon EC2 instance IDs that you want to retrieve status on. Amazon EC2 instance IDs use a 17-character format, for example: i-1234567890abcdef0 . To retrieve all instances in the game server group, leave this parameter empty.

(string)

Syntax:

"string" "string" ...

--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json

  • text

  • table

  • yaml

  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on

  • off

  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64

  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Output

GameServerInstances -> (list)

The collection of requested game server instances.

(structure)

This data type is used with the GameLift FleetIQ and game server groups.

Additional properties, including status, that describe an EC2 instance in a game server group. Instance configurations are set with game server group properties (see DescribeGameServerGroup and with the EC2 launch template that was used when creating the game server group.

Retrieve game server instances for a game server group by calling DescribeGameServerInstances .

GameServerGroupName -> (string)

A developer-defined identifier for the game server group that includes the game server instance. The name is unique for each Region in each Amazon Web Services account.

GameServerGroupArn -> (string)

A generated unique identifier for the game server group that includes the game server instance.

InstanceId -> (string)

The unique identifier for the instance where the game server is running. This ID is available in the instance metadata. EC2 instance IDs use a 17-character format, for example: i-1234567890abcdef0 .

InstanceStatus -> (string)

Current status of the game server instance.

  • ACTIVE – The instance is viable for hosting game servers.

  • DRAINING – The instance is not viable for hosting game servers. Existing game servers are in the process of ending, and new game servers are not started on this instance unless no other resources are available. When the instance is put in DRAINING, a new instance is started up to replace it. Once the instance has no UTILIZED game servers, it will be terminated in favor of the new instance.

  • SPOT_TERMINATING – The instance is in the process of shutting down due to a Spot instance interruption. No new game servers are started on this instance.

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.
