Bases: CfnResource

A CloudFormation AWS::GameLift::GameServerGroup.

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

Creates a GameLift FleetIQ game server group for managing game hosting on a collection of Amazon EC2 instances for game hosting. This operation creates the game server group, creates an Auto Scaling group in your AWS account , and establishes a link between the two groups. You can view the status of your game server groups in the GameLift console. Game server group metrics and events are emitted to Amazon CloudWatch.

Before creating a new game server group, you must have the following:

An Amazon EC2 launch template that specifies how to launch Amazon EC2 instances with your game server build. For more information, see Launching an Instance from a Launch Template in the Amazon EC2 User Guide .
An IAM role that extends limited access to your AWS account to allow GameLift FleetIQ to create and interact with the Auto Scaling group. For more information, see Create IAM roles for cross-service interaction in the GameLift FleetIQ Developer Guide .

To create a new game server group, specify a unique group name, IAM role and Amazon EC2 launch template, and provide a list of instance types that can be used in the group. You must also set initial maximum and minimum limits on the group’s instance count. You can optionally set an Auto Scaling policy with target tracking based on a GameLift FleetIQ metric.

Once the game server group and corresponding Auto Scaling group are created, you have full access to change the Auto Scaling group’s configuration as needed. Several properties that are set when creating a game server group, including maximum/minimum size and auto-scaling policy settings, must be updated directly in the Auto Scaling group. Keep in mind that some Auto Scaling group properties are periodically updated by GameLift FleetIQ as part of its balancing activities to optimize for availability and cost.

Create a new AWS::GameLift::GameServerGroup.

Parameters:

scope (Construct) –
- scope in which this resource is defined.
id (str) –
- scoped id of the resource.
game_server_group_name (str) – A developer-defined identifier for the game server group. The name is unique for each Region in each AWS account.
instance_definitions (Union[IResolvable, Sequence[Union[IResolvable, InstanceDefinitionProperty, Dict[str, Any]]]]) – The set of Amazon EC2 instance types that Amazon GameLift FleetIQ can use when balancing and automatically scaling instances in the corresponding Auto Scaling group.
role_arn (str) – The Amazon Resource Name ( ARN ) for an IAM role that allows Amazon GameLift to access your Amazon EC2 Auto Scaling groups.
auto_scaling_policy (Union[IResolvable, AutoScalingPolicyProperty, Dict[str, Any], None]) – Configuration settings to define a scaling policy for the Auto Scaling group that is optimized for game hosting. The scaling policy uses the metric "PercentUtilizedGameServers" to maintain a buffer of idle game servers that can immediately accommodate new games and players. After the Auto Scaling group is created, update this value directly in the Auto Scaling group using the AWS console or APIs.
balancing_strategy (Optional[str]) – Indicates how Amazon GameLift FleetIQ balances the use of Spot Instances and On-Demand Instances in the game server group. Method options include the following: - SPOT_ONLY - Only Spot Instances are used in the game server group. If Spot Instances are unavailable or not viable for game hosting, the game server group provides no hosting capacity until Spot Instances can again be used. Until then, no new instances are started, and the existing nonviable Spot Instances are terminated (after current gameplay ends) and are not replaced. - SPOT_PREFERRED - (default value) Spot Instances are used whenever available in the game server group. If Spot Instances are unavailable, the game server group continues to provide hosting capacity by falling back to On-Demand Instances. Existing nonviable Spot Instances are terminated (after current gameplay ends) and are replaced with new On-Demand Instances. - ON_DEMAND_ONLY - Only On-Demand Instances are used in the game server group. No Spot Instances are used, even when available, while this balancing strategy is in force.
delete_option (Optional[str]) – The type of delete to perform. To delete a game server group, specify the DeleteOption . Options include the following: - SAFE_DELETE – (default) Terminates the game server group and Amazon EC2 Auto Scaling group only when it has no game servers that are in UTILIZED status. - FORCE_DELETE – Terminates the game server group, including all active game servers regardless of their utilization status, and the Amazon EC2 Auto Scaling group. - RETAIN – Does a safe delete of the game server group but retains the Amazon EC2 Auto Scaling group as is.
game_server_protection_policy (Optional[str]) – A flag that indicates whether instances in the game server group are protected from early termination. Unprotected instances that have active game servers running might be terminated during a scale-down event, causing players to be dropped from the game. Protected instances cannot be terminated while there are active game servers running except in the event of a forced game server group deletion (see ). An exception to this is with Spot Instances, which can be terminated by AWS regardless of protection status.
launch_template (Union[IResolvable, LaunchTemplateProperty, Dict[str, Any], None]) – The Amazon EC2 launch template that contains configuration settings and game server code to be deployed to all instances in the game server group. You can specify the template using either the template name or ID. For help with creating a launch template, see Creating a Launch Template for an Auto Scaling Group in the Amazon Elastic Compute Cloud Auto Scaling User Guide . After the Auto Scaling group is created, update this value directly in the Auto Scaling group using the AWS console or APIs. .. epigraph:: If you specify network interfaces in your launch template, you must explicitly set the property AssociatePublicIpAddress to “true”. If no network interface is specified in the launch template, Amazon GameLift FleetIQ uses your account’s default VPC.
max_size (Union[int, float, None]) – The maximum number of instances allowed in the Amazon EC2 Auto Scaling group. During automatic scaling events, Amazon GameLift FleetIQ and EC2 do not scale up the group above this maximum. After the Auto Scaling group is created, update this value directly in the Auto Scaling group using the AWS console or APIs.
min_size (Union[int, float, None]) – The minimum number of instances allowed in the Amazon EC2 Auto Scaling group. During automatic scaling events, Amazon GameLift FleetIQ and Amazon EC2 do not scale down the group below this minimum. In production, this value should be set to at least 1. After the Auto Scaling group is created, update this value directly in the Auto Scaling group using the AWS console or APIs.
tags (Optional[Sequence[Union[CfnTag, Dict[str, Any]]]]) – A list of labels to assign to the new game server group resource. Tags are developer-defined key-value pairs. Tagging AWS resources is useful for resource management, access management, and cost allocation. For more information, see Tagging AWS Resources in the AWS General Reference . Once the resource is created, you can use TagResource, UntagResource, and ListTagsForResource to add, remove, and view tags, respectively. The maximum tag limit may be lower than stated. See the AWS General Reference for actual tagging limits.
vpc_subnets (Optional[Sequence[str]]) – A list of virtual private cloud (VPC) subnets to use with instances in the game server group. By default, all Amazon GameLift FleetIQ-supported Availability Zones are used. You can use this parameter to specify VPCs that you’ve set up. This property cannot be updated after the game server group is created, and the corresponding Auto Scaling group will always use the property value that is set with this request, even if the Auto Scaling group is updated directly.

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:

target (CfnResource) –

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:

policy (Optional[RemovalPolicy]) –
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type:

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:: attribute_name (str) – The name of the attribute.
Return type:: Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters:

key (str) –

See:

Return type:

Any

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

AutoScalingPolicyProperty

class CfnGameServerGroup.AutoScalingPolicyProperty(*, target_tracking_configuration, estimated_instance_warmup=None)

Bases: object

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

Configuration settings for intelligent automatic scaling that uses target tracking. After the Auto Scaling group is created, all updates to Auto Scaling policies, including changing this policy and adding or removing other policies, is done directly on the Auto Scaling group.

Parameters:

target_tracking_configuration (Union[IResolvable, TargetTrackingConfigurationProperty, Dict[str, Any]]) – Settings for a target-based scaling policy applied to Auto Scaling group. These settings are used to create a target-based policy that tracks the GameLift FleetIQ metric PercentUtilizedGameServers and specifies a target value for the metric. As player usage changes, the policy triggers to adjust the game server group capacity so that the metric returns to the target value.
estimated_instance_warmup (Union[int, float, None]) – Length of time, in seconds, it takes for a new instance to start new game server processes and register with Amazon GameLift FleetIQ. Specifying a warm-up time can be useful, particularly with game servers that take a long time to start up, because it avoids prematurely starting new instances.
