CreateContainerFleet

Creates a managed fleet of Amazon Elastic Compute Cloud (Amazon EC2) instances to host your containerized game servers. Use this operation to define how to deploy a container architecture onto each fleet instance and configure fleet settings. You can create a container fleet in any AWS Regions that Amazon GameLift supports for multi-location fleets. A container fleet can be deployed to a single location or multiple locations. Container fleets are deployed with Amazon Linux 2023 as the instance operating system.

Define the fleet's container architecture using container group definitions. Each fleet can have one of the following container group types:

The game server container group runs your game server build and dependent software. Amazon GameLift deploys one or more replicas of this container group to each fleet instance. The number of replicas depends on the computing capabilities of the fleet instance in use.
An optional per-instance container group might be used to run other software that only needs to run once per instance, such as background services, logging, or test processes. One per-instance container group is deployed to each fleet instance.

Each container group can include the definition for one or more containers. A container definition specifies a container image that is stored in an Amazon Elastic Container Registry (Amazon ECR) public or private repository.

Request options

Use this operation to make the following types of requests. Most fleet settings have default values, so you can create a working fleet with a minimal configuration and default values, which you can customize later.

Create a fleet with no container groups. You can configure a container fleet and then add container group definitions later. In this scenario, no fleet instances are deployed, and the fleet can't host game sessions until you add a game server container group definition. Provide the following required parameter values:
- FleetRoleArn
Create a fleet with a game server container group. Provide the following required parameter values:
- FleetRoleArn
- GameServerContainerGroupDefinitionName
Create a fleet with a game server container group and a per-instance container group. Provide the following required parameter values:
- FleetRoleArn
- GameServerContainerGroupDefinitionName
- PerInstanceContainerGroupDefinitionName

Results

If successful, this operation creates a new container fleet resource, places it in PENDING status, and initiates the fleet creation workflow. For fleets with container groups, this workflow starts a fleet deployment and transitions the status to ACTIVE. Fleets without a container group are placed in CREATED status.

You can update most of the properties of a fleet, including container group definitions, and deploy the update across all fleet instances. Use a fleet update to deploy a new game server version update across the container fleet.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

The request accepts the following data in JSON format.

Note

In the following list, the required parameters are described first.

FleetRoleArn

The unique identifier for an AWS Identity and Access Management (IAM) role with permissions to run your containers on resources that are managed by Amazon GameLift. Use an IAM service role with the GameLiftContainerFleetPolicy managed policy attached. For more information, see Set up an IAM service role. You can't change this fleet property after the fleet is created.

IAM role ARN values use the following pattern: arn:aws:iam::[AWS account]:role/[role name].

Type: String

Length Constraints: Minimum length of 1. Maximum length of 512.

Pattern: [a-zA-Z0-9:/-]+

Required: Yes

BillingType

Indicates whether to use On-Demand or Spot instances for this fleet. Learn more about when to use On-Demand versus Spot Instances. This fleet property can't be changed after the fleet is created.

By default, this property is set to ON_DEMAND.

You can't update this fleet property later.

Type: String

Valid Values: ON_DEMAND | SPOT

Required: No

Description

A meaningful description of the container fleet.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Required: No

GameServerContainerGroupDefinitionName

A container group definition resource that describes how to deploy containers with your game server build and support software onto each fleet instance. You can specify the container group definition's name to use the latest version. Alternatively, provide an ARN value with a specific version number.

Create a container group definition by calling CreateContainerGroupDefinition. This operation creates a ContainerGroupDefinition resource.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 512.

Pattern: ^[a-zA-Z0-9\-]+$|^arn:.*:containergroupdefinition\/[a-zA-Z0-9\-]+(:[0-9]+)?$

Required: No

GameServerContainerGroupsPerInstance

The number of times to replicate the game server container group on each fleet instance.

By default, Amazon GameLift calculates the maximum number of game server container groups that can fit on each instance. This calculation is based on the CPU and memory resources of the fleet's instance type). To use the calculated maximum, don't set this parameter. If you set this number manually, Amazon GameLift uses your value as long as it's less than the calculated maximum.

Type: Integer

Valid Range: Minimum value of 1. Maximum value of 5000.

Required: No

GameSessionCreationLimitPolicy

A policy that limits the number of game sessions that each individual player can create on instances in this fleet. The limit applies for a specified span of time.

Type: GameSessionCreationLimitPolicy object

Required: No

InstanceConnectionPortRange

The set of port numbers to open on each fleet instance. A fleet's connection ports map to container ports that are configured in the fleet's container group definitions.

By default, Amazon GameLift calculates an optimal port range based on your fleet configuration. To use the calculated range, don't set this parameter. The values are:

Port range: 4192 to a number calculated based on your fleet configuration. Amazon GameLift uses the following formula: 4192 + [# of game server container groups per fleet instance] * [# of container ports in the game server container group definition] + [# of container ports in the game server container group definition]

You can also choose to manually set this parameter. When manually setting this parameter, you must use port numbers that match the fleet's inbound permissions port range.

Note

If you set values manually, Amazon GameLift no longer calculates a port range for you, even if you later remove the manual settings.

Type: ConnectionPortRange object

Required: No

InstanceInboundPermissions

The IP address ranges and port settings that allow inbound traffic to access game server processes and other processes on this fleet. As a best practice, when remotely accessing a fleet instance, we recommend opening ports only when you need them and closing them when you're finished.

By default, Amazon GameLift calculates an optimal port range based on your fleet configuration. To use the calculated range, don't set this parameter. The values are:

Protocol: UDP
Port range: 4192 to a number calculated based on your fleet configuration. Amazon GameLift uses the following formula: 4192 + [# of game server container groups per fleet instance] * [# of container ports in the game server container group definition] + [# of container ports in the game server container group definition]

You can also choose to manually set this parameter. When manually setting this parameter, you must use port numbers that match the fleet's connection port range.

Note

If you set values manually, Amazon GameLift no longer calculates a port range for you, even if you later remove the manual settings.

Type: Array of IpPermission objects

Array Members: Maximum number of 50 items.

Required: No

InstanceType

The Amazon EC2 instance type to use for all instances in the fleet. For multi-location fleets, the instance type must be available in the home region and all remote locations. Instance type determines the computing resources and processing power that's available to host your game servers. This includes including CPU, memory, storage, and networking capacity.

By default, Amazon GameLift selects an instance type that fits the needs of your container groups and is available in all selected fleet locations. You can also choose to manually set this parameter. See Amazon Elastic Compute Cloud Instance Types for detailed descriptions of Amazon EC2 instance types.

You can't update this fleet property later.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 1024.

Required: No

Locations

A set of locations to deploy container fleet instances to. You can add any AWS Region or Local Zone that's supported by Amazon GameLift. Provide a list of one or more AWS Region codes, such as us-west-2, or Local Zone names. Also include the fleet's home Region, which is the AWS Region where the fleet is created. For a list of supported Regions and Local Zones, see Amazon GameLift service locations for managed hosting.

Type: Array of LocationConfiguration objects

Array Members: Minimum number of 1 item. Maximum number of 100 items.

Required: No

LogConfiguration

A method for collecting container logs for the fleet. Amazon GameLift saves all standard output for each container in logs, including game session logs. You can select from the following methods:

CLOUDWATCH -- Send logs to an Amazon CloudWatch log group that you define. Each container emits a log stream, which is organized in the log group.
S3 -- Store logs in an Amazon S3 bucket that you define.
NONE -- Don't collect container logs.

By default, this property is set to CLOUDWATCH.

Amazon GameLift requires permissions to send logs other AWS services in your account. These permissions are included in the IAM fleet role for this container fleet (see FleetRoleArn).

Type: LogConfiguration object

Required: No

MetricGroups

The name of an AWS CloudWatch metric group to add this fleet to. You can use a metric group to aggregate metrics for multiple fleets. You can specify an existing metric group name or use a new name to create a new metric group. Each fleet can have only one metric group, but you can change this value at any time.

Type: Array of strings

Array Members: Maximum number of 1 item.

Length Constraints: Minimum length of 1. Maximum length of 255.

Required: No

NewGameSessionProtectionPolicy

Determines whether Amazon GameLift can shut down game sessions on the fleet that are actively running and hosting players. Amazon GameLift might prompt an instance shutdown when scaling down fleet capacity or when retiring unhealthy instances. You can also set game session protection for individual game sessions using UpdateGameSession.

NoProtection -- Game sessions can be shut down during active gameplay.
FullProtection -- Game sessions in ACTIVE status can't be shut down.

By default, this property is set to NoProtection.

Type: String

Valid Values: NoProtection | FullProtection

Required: No

PerInstanceContainerGroupDefinitionName

The name of a container group definition resource that describes a set of axillary software. A fleet instance has one process for executables in this container group. A per-instance container group is optional. You can update the fleet to add or remove a per-instance container group at any time. You can specify the container group definition's name to use the latest version. Alternatively, provide an ARN value with a specific version number.

Create a container group definition by calling https://docs.aws.amazon.com/gamelift/latest/apireference/API_CreateContainerGroupDefinition.html. This operation creates a https://docs.aws.amazon.com/gamelift/latest/apireference/API_ContainerGroupDefinition.html resource.

Type: String

Length Constraints: Minimum length of 1. Maximum length of 512.

Pattern: ^[a-zA-Z0-9\-]+$|^arn:.*:containergroupdefinition\/[a-zA-Z0-9\-]+(:[0-9]+)?$

Required: No

Tags

A list of labels to assign to the new fleet resource. Tags are developer-defined key-value pairs. Tagging AWS resources are useful for resource management, access management and cost allocation. For more information, see Tagging AWS Resources in the AWS General Reference.
