Properties

BuildId

A unique identifier for a build to be deployed on the new fleet. If you are deploying the fleet with a custom game build, you must specify this property. The build must have been successfully uploaded to Amazon GameLift and be in a READY status. This fleet setting cannot be changed once the fleet is created.

Required: Conditional

Type: String

Pattern: ^build-\S+|^arn:.*:build\/build-\S+

Update requires: Replacement

CertificateConfiguration

Indicates whether to generate a TLS/SSL certificate for the new fleet. TLS certificates are used for encrypting traffic between game clients and game servers running on GameLift. If this parameter is not set, certificate generation is disabled. This fleet setting cannot be changed once the fleet is created. Learn more at Securing Client/Server Communication.

Note: This feature requires the AWS Certificate Manager (ACM) service, which is available in the AWS global partition but not in all other partitions. When working in a partition that does not support this feature, a request for a new fleet with certificate generation results fails with a 4xx unsupported region error.

Required: No

Type: CertificateConfiguration

Update requires: Replacement

Description

A human-readable description of a fleet.

Required: No

Type: String

Minimum: 1

FleetType

Indicates whether to use On-Demand instances or Spot instances for this fleet. If empty, the default is ON_DEMAND. Both categories of instances use identical hardware and configurations based on the instance type selected for this fleet. Learn more about On-Demand versus Spot Instances.

Required: No

Type: String

Allowed values: ON_DEMAND | SPOT

Update requires: Replacement

InstanceRoleARN

A unique identifier for an AWS IAM role that manages access to your AWS services. With an instance role ARN set, any application that runs on an instance in this fleet can assume the role, including install scripts, server processes, and daemons (background processes). Create a role or look up a role's ARN from the IAM dashboard in the AWS Management Console. Learn more about using on-box credentials for your game servers at Access external resources from a game server.

Required: No

Type: String

Minimum: 1

Update requires: Replacement

LogPaths

This parameter is no longer used. When hosting a custom game build, specify where Amazon GameLift should store log files using the Amazon GameLift server API call ProcessReady(). See more information in the Server API Reference.

Required: No

Type: List of String

Update requires: Replacement

MaxSize

The maximum value that is allowed for the fleet's instance count. When creating a new fleet, GameLift automatically sets this value to "1". Once the fleet is active, you can change this value.

Required: No

Type: Integer

Minimum: 0

Update requires: No interruption

MetricGroups

The name of an Amazon CloudWatch metric group. A metric group aggregates the metrics for all fleets in the group. Specify a string containing the metric group name. You can use an existing name or use a new name to create a new metric group. Currently, this parameter can have only one string.

Required: No

Type: List of String

Maximum: 1

Update requires: No interruption

MinSize

The minimum value allowed for the fleet's instance count. When creating a new fleet, GameLift automatically sets this value to "0". After the fleet is active, you can change this value.

Required: No

Type: Integer

Minimum: 0

Update requires: No interruption

Name

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

Required: Yes

Type: String

Minimum: 1

Maximum: 1024

Update requires: No interruption

NewGameSessionProtectionPolicy

A game session protection policy to apply to all game sessions hosted on instances in this fleet. When protected, active game sessions cannot be terminated during a scale-down event. If this parameter is not set, instances in this fleet default to no protection. You can change a fleet's protection policy to affect future game sessions on the fleet. You can also set protection for individual game sessions.

Required: No

Type: String

Allowed values: FullProtection | NoProtection

Update requires: No interruption

PeerVpcAwsAccountId

A unique identifier for the AWS account with the VPC that you want to peer your Amazon GameLift fleet with. You can find your account ID in the AWS Management Console under account settings.

Required: No

Type: String

Minimum: 1

Maximum: 1024

Update requires: Replacement

PeerVpcId

A unique identifier for a VPC with resources to be accessed by your Amazon GameLift fleet. The VPC must be in the same Region as your fleet. To look up a VPC ID, use the VPC Dashboard in the AWS Management Console. Learn more about VPC peering in VPC Peering with Amazon GameLift Fleets.

Required: No

Type: String

Minimum: 1

Maximum: 1024

Update requires: Replacement

ResourceCreationLimitPolicy

A policy that limits the number of game sessions an individual player can create over a span of time for this fleet.

Required: No

Type: ResourceCreationLimitPolicy

Update requires: No interruption

RuntimeConfiguration

Instructions for launching server processes on each instance in the fleet. Server processes run either a custom game build executable or a Realtime script. The runtime configuration defines the server executables or launch script file, launch parameters, and the number of processes to run concurrently on each instance. When creating a fleet, the runtime configuration must have at least one server process configuration; otherwise the request fails with an invalid request exception.

This parameter is required unless the parameters ServerLaunchPath and ServerLaunchParameters are defined. Runtime configuration has replaced these parameters, but fleets that use them will continue to work.

Required: Conditional

Type: RuntimeConfiguration

Update requires: No interruption

ScriptId

A unique identifier for a Realtime script to be deployed on a new Realtime Servers fleet. The script must have been successfully uploaded to Amazon GameLift. This fleet setting cannot be changed once the fleet is created.

Note: It is not currently possible to use the !Ref command to reference a script created with a CloudFormation template for the fleet property ScriptId. Instead, use Fn::GetAtt Script.Arn or Fn::GetAtt Script.Id to retrieve either of these properties as input for ScriptId. Alternatively, enter a ScriptId string manually.

Required: Conditional

Type: String

Pattern: ^script-\S+|^arn:.*:script\/script-\S+

Update requires: Replacement

ServerLaunchParameters

This parameter is no longer used but is retained for backward compatibility. Instead, specify server launch parameters in the RuntimeConfiguration parameter. A request must specify either a runtime configuration or values for both ServerLaunchParameters and ServerLaunchPath.

Required: Conditional

Type: String

Minimum: 1

Maximum: 1024

Update requires: Replacement

ServerLaunchPath

This parameter is no longer used. Instead, specify a server launch path using the RuntimeConfiguration parameter. Requests that specify a server launch path and launch parameters instead of a runtime configuration will continue to work.

Required: Conditional

Type: String

Minimum: 1

Maximum: 1024

Update requires: Replacement

Return values

Ref

When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the fleet ID, such as fleet-1111aaaa-22bb-33cc-44dd-5555eeee66ff.

For more information about using the Ref function, see Ref.

Examples

Create GameLift fleet with a Build

The following example creates and configures a GameLift fleet for a custom game build. The fleet uses a Ref intrinsic function to specify a build, which can be declared elsewhere in the same template. The example syntax for log path and server launch path uses values for a Windows build.

Note: the JSON example shows how to escape the slashes (\\).

Create GameLift fleet with a Script

The following example creates and configures a GameLift fleet to run Realtime Servers. The fleet uses a GetAtt intrinsic function to specify a script, which can be declared elsewhere in the same template. Note that the syntax example for the log path and server launch path are for Linux, as all Realtime Servers are deployed with Linux.
