Changes (request, response)
Request

{'InstanceRoleArn': 'string'}

Response

{'FleetAttributes': {'InstanceRoleArn': 'string'}}

Creates a new fleet to run your game servers. A fleet is a set of Amazon Elastic Compute Cloud (Amazon EC2) instances, each of which can run multiple server processes to host game sessions. You set up a fleet to use instances with certain hardware specifications (see Amazon EC2 Instance Types ), and deploy your game build to the fleet.

To create a new fleet, you must provide the following: (1) a fleet name, (2) an EC2 instance type, (3) the build ID for your game build, and (4) a run-time configuration, which specifies the server processes to run on each instance in the fleet. If fleet type is not set, the new fleet will use on-demand instances by default.

If the CreateFleet call is successful, Amazon GameLift performs the following tasks. You can track the process of a fleet by checking the fleet status or by monitoring fleet creation events:

Creates a fleet record. Status: NEW .
Begins writing events to the fleet event log, which can be accessed in the Amazon GameLift console. Sets the fleet's target capacity to 1 (desired instances), which triggers Amazon GameLift to start one new EC2 instance.
Downloads the game build to the new instance and installs it. Statuses: DOWNLOADING , VALIDATING , BUILDING .
Starts launching server processes on the instance. If the fleet is configured to run multiple server processes per instance, Amazon GameLift staggers each launch by a few seconds. Status: ACTIVATING .
Sets the fleet's status to ACTIVE as soon as one server process is ready to host a game session.

type Name

string

param Name

[REQUIRED]

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

type Description

string

param Description

Human-readable description of a fleet.

type BuildId

string

param BuildId

[REQUIRED]

Unique identifier for a build to be deployed on the new fleet. 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.

type ServerLaunchPath

string

param 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 run-time configuration will continue to work.)

type ServerLaunchParameters

string

param ServerLaunchParameters

This parameter is no longer used. Instead, specify server launch parameters in the RuntimeConfiguration parameter. (Requests that specify a server launch path and launch parameters instead of a run-time configuration will continue to work.)

type LogPaths

list

param LogPaths

This parameter is no longer used. Instead, to specify where Amazon GameLift should store log files once a server process shuts down, use the Amazon GameLift server API ProcessReady() and specify one or more directory paths in logParameters . See more information in the Server API Reference.

(string) --

type EC2InstanceType

string

param EC2InstanceType

[REQUIRED]

Name of an EC2 instance type that is supported in Amazon GameLift. A fleet instance type determines the computing resources of each instance in the fleet, including CPU, memory, storage, and networking capacity. Amazon GameLift supports the following EC2 instance types. See Amazon EC2 Instance Types for detailed descriptions.

type EC2InboundPermissions

list

param EC2InboundPermissions

Range of IP addresses and port settings that permit inbound traffic to access server processes running on the fleet. If no inbound permissions are set, including both IP address range and port range, the server processes in the fleet cannot accept connections. You can specify one or more sets of permissions for a fleet.

(dict) --

A range of IP addresses and port settings that allow inbound traffic to connect to server processes on Amazon GameLift. Each game session hosted on a fleet is assigned a unique combination of IP address and port number, which must fall into the fleet's allowed ranges. This combination is included in the GameSession object.
- FromPort (integer) -- [REQUIRED]
  
  Starting value for a range of allowed port numbers.
- ToPort (integer) -- [REQUIRED]
  
  Ending value for a range of allowed port numbers. Port numbers are end-inclusive. This value must be higher than FromPort .
- IpRange (string) -- [REQUIRED]
  
  Range of allowed IP addresses. This value must be expressed in CIDR notation. Example: " 000.000.000.000/[subnet mask] " or optionally the shortened version " 0.0.0.0/[subnet mask] ".
- Protocol (string) -- [REQUIRED]
  
  Network communication protocol used by the fleet.

type NewGameSessionProtectionPolicy

string

param NewGameSessionProtectionPolicy

Game session protection policy to apply to all instances in this fleet. If this parameter is not set, instances in this fleet default to no protection. You can change a fleet's protection policy using UpdateFleetAttributes, but this change will only affect sessions created after the policy change. You can also set protection for individual instances 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.

type RuntimeConfiguration

dict

param RuntimeConfiguration

Instructions for launching server processes on each instance in the fleet. The run-time configuration for a fleet has a collection of server process configurations, one for each type of server process to run on an instance. A server process configuration specifies the location of the server executable, launch parameters, and the number of concurrent processes with that configuration to maintain on each instance. A CreateFleet request must include a run-time configuration with at least one server process configuration; otherwise the request fails with an invalid request exception. (This parameter replaces the parameters ServerLaunchPath and ServerLaunchParameters ; requests that contain values for these parameters instead of a run-time configuration will continue to work.)

ServerProcesses (list) --

Collection of server process configurations that describe which server processes to run on each instance in a fleet.
- (dict) --
  
  A set of instructions for launching server processes on each instance in a fleet. Each instruction set identifies the location of the server executable, optional launch parameters, and the number of server processes with this configuration to maintain concurrently on the instance. Server process configurations make up a fleet's RuntimeConfiguration .
  - LaunchPath (string) -- [REQUIRED]
    
    Location of the server executable in a game build. All game builds are installed on instances at the root : for Windows instances C:\game , and for Linux instances /local/game . A Windows game build with an executable file located at MyGame\latest\server.exe must have a launch path of " C:\game\MyGame\latest\server.exe ". A Linux game build with an executable file located at MyGame/latest/server.exe must have a launch path of " /local/game/MyGame/latest/server.exe ".
  - Parameters (string) --
    
    Optional list of parameters to pass to the server executable on launch.
  - ConcurrentExecutions (integer) -- [REQUIRED]
    
    Number of server processes using this configuration to run concurrently on an instance.
MaxConcurrentGameSessionActivations (integer) --

Maximum number of game sessions with status ACTIVATING to allow on an instance simultaneously. This setting limits the amount of instance resources that can be used for new game activations at any one time.
GameSessionActivationTimeoutSeconds (integer) --

Maximum amount of time (in seconds) that a game session can remain in status ACTIVATING . If the game session is not active before the timeout, activation is terminated and the game session status is changed to TERMINATED .

type ResourceCreationLimitPolicy

dict

param ResourceCreationLimitPolicy

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

NewGameSessionsPerCreator (integer) --

Maximum number of game sessions that an individual can create during the policy period.
PolicyPeriodInMinutes (integer) --

Time span used in evaluating the resource creation limit policy.

type MetricGroups

list

param MetricGroups

Name of an Amazon CloudWatch metric group to add this fleet to. A metric group aggregates the metrics for all fleets in the group. Specify an existing metric group name, or provide a new name to create a new metric group. A fleet can only be included in one metric group at a time.

(string) --

type PeerVpcAwsAccountId

string

param PeerVpcAwsAccountId

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.

type PeerVpcId

string

param PeerVpcId

Unique identifier for a VPC with resources to be accessed by your Amazon GameLift fleet. The VPC must be in the same region where your fleet is deployed. Look up a VPC ID using the VPC Dashboard in the AWS Management Console. Learn more about VPC peering in VPC Peering with Amazon GameLift Fleets.

type FleetType

string

param 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. You can acquire on-demand instances at any time for a fixed price and keep them as long as you need them. Spot instances have lower prices, but spot pricing is variable, and while in use they can be interrupted (with a two-minute notification). Learn more about Amazon GameLift spot instances with at Set up Access to External Services.

type InstanceRoleArn

string

param InstanceRoleArn

Unique identifier for an AWS IAM role that manages access to your AWS services. Any application that runs on an instance in this fleet can assume the role, including install scripts, server processs, daemons (background processes).

DescribeFleetAttributes (updated)

Link ¶
Changes (response)

{'FleetAttributes': {'InstanceRoleArn': 'string'}}

Retrieves fleet properties, including metadata, status, and configuration, for one or more fleets. You can request attributes for all fleets, or specify a list of one or more fleet IDs. When requesting multiple fleets, use the pagination parameters to retrieve results as a set of sequential pages. If successful, a FleetAttributes object is returned for each requested fleet ID. When specifying a list of fleet IDs, attribute objects are returned only for fleets that currently exist.

Note

Some API actions may limit the number of fleet IDs allowed in one request. If a request exceeds this limit, the request fails and the error message includes the maximum allowed.

Use the Amazon GameLift console to access stored logs.
