update-fleet-capacity

Description

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

Updates capacity settings for a managed EC2 fleet or container fleet. For these fleets, you adjust capacity by changing the number of instances in the fleet. Fleet capacity determines the number of game sessions and players that the fleet can host based on its configuration. For fleets with multiple locations, use this operation to manage capacity settings in each location individually.

Use this operation to set these fleet capacity properties:

  • Minimum/maximum size: Set hard limits on the number of Amazon EC2 instances allowed. If Amazon GameLift receives a request--either through manual update or automatic scaling--it won't change the capacity to a value outside of this range.
  • Desired capacity: As an alternative to automatic scaling, manually set the number of Amazon EC2 instances to be maintained. Before changing a fleet's desired capacity, check the maximum capacity of the fleet's Amazon EC2 instance type by calling DescribeEC2InstanceLimits .

To update capacity for a fleet's home Region, or if the fleet has no remote locations, omit the Location parameter. The fleet must be in ACTIVE status.

To update capacity for a fleet's remote location, set the Location parameter to the location to update. The location must be in ACTIVE status.

If successful, Amazon GameLift updates the capacity settings and returns the identifiers for the updated fleet and/or location. If a requested change to desired capacity exceeds the instance type's limit, the LimitExceeded exception occurs.

Updates often prompt an immediate change in fleet capacity, such as when current capacity is different than the new desired capacity or outside the new limits. In this scenario, Amazon GameLift automatically initiates steps to add or remove instances in the fleet location. You can track a fleet's current capacity by calling DescribeFleetCapacity or DescribeFleetLocationCapacity .

Options

--fleet-id (string)

A unique identifier for the fleet to update capacity settings for. You can use either the fleet ID or ARN value.

--desired-instances (integer)

The number of Amazon EC2 instances you want to maintain in the specified fleet location. This value must fall between the minimum and maximum size limits. Changes in desired instance value can take up to 1 minute to be reflected when viewing the fleet's capacity settings.

--min-size (integer)

The minimum number of instances that are allowed in the specified fleet location. If this parameter is not set, the default is 0.

--max-size (integer)

The maximum number of instances that are allowed in the specified fleet location. If this parameter is not set, the default is 1.

--location (string)

The name of a remote location to update fleet capacity settings for, in the form of an Amazon Web Services Region code such as us-west-2 .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

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

--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.

Output

FleetId -> (string)

A unique identifier for the fleet that was updated.

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 .

Location -> (string)

The remote location being updated, expressed as an Amazon Web Services Region code, such as us-west-2 .
