[ aws . gamelift ]



Updates a fleet’s mutable attributes, such as game session protection and resource creation limits.

To update fleet attributes, specify the fleet ID and the property values that you want to change. If successful, Amazon GameLift returns the identifiers for the updated fleet.

--fleet-id (string)

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

--name (string)

A descriptive label that is associated with a fleet. Fleet names do not need to be unique.

--description (string)

A human-readable description of a fleet.

--new-game-session-protection-policy (string)

The game session protection policy to apply to all new game sessions created in this fleet. Game sessions that already exist are not affected. You can set protection for individual game sessions using UpdateGameSession .

  • NoProtection – The game session can be terminated during a scale-down event.
  • FullProtection – If the game session is in an ACTIVE status, it cannot be terminated during a scale-down event.

Possible values:

  • NoProtection
  • FullProtection

--resource-creation-limit-policy (structure)

Policy settings that limit the number of game sessions an individual player can create over a span of time.

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.

PolicyPeriodInMinutes -> (integer)

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

Shorthand Syntax:


JSON Syntax:

  "NewGameSessionsPerCreator": integer,
  "PolicyPeriodInMinutes": integer

--metric-groups (list)

The name of a metric group to add this fleet to. Use a metric group in Amazon CloudWatch to aggregate the metrics from multiple fleets. Provide an existing metric group name, or create a new metric group by providing a new name. A fleet can only be in one metric group at a time.



"string" "string" ...

--anywhere-configuration (structure)

Amazon GameLift Anywhere configuration options.

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 .

Shorthand Syntax:


JSON Syntax:

  "Cost": "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.

--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.


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 .
