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 for more information), and deploy your game build to run on each instance.

To create a new fleet, you must specify the following: (1) a fleet name, (2) the build ID of a successfully uploaded game build, (3) an EC2 instance type, and (4) a run-time configuration, which describes the server processes to run on each instance in the fleet. If you don't specify a fleet type (on-demand or spot), the new fleet uses on-demand instances by default.

You can also configure the new fleet with the following settings:

If you use Amazon CloudWatch for metrics, you can add the new fleet to a metric group. By adding multiple fleets to a metric group, you can view aggregated metrics for all the fleets in the group.

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.

[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 a metric group to add this fleet to. A metric group tracks metrics across all fleets in the group. Use an existing metric group name to add this fleet to the group, or use 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. To get VPC information, including IDs, use the Virtual Private Cloud service tools, including the VPC Dashboard in the AWS Management Console.

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).

CreateGameSession (updated) Link ¶
Changes (response)
{'GameSession': {'StatusReason': 'INTERRUPTED'}}

Creates a multiplayer game session for players. This action creates a game session record and assigns an available server process in the specified fleet to host the game session. A fleet must have an ACTIVE status before a game session can be created in it.

To create a game session, specify either fleet ID or alias ID and indicate a maximum number of players to allow in the game session. You can also provide a name and game-specific properties for this game session. If successful, a GameSession object is returned containing the game session properties and other settings you specified.

Idempotency tokens. You can add a token that uniquely identifies game session requests. This is useful for ensuring that game session requests are idempotent. Multiple requests with the same idempotency token are processed only once; subsequent requests return the original result. All response values are the same with the exception of game session status, which may change.

Resource creation limits. If you are creating a game session on a fleet with a resource creation limit policy in force, then you must specify a creator ID. Without this ID, Amazon GameLift has no way to evaluate the policy for this new game session request.

Player acceptance policy. By default, newly created game sessions are open to new players. You can restrict new player access by using UpdateGameSession to change the game session's player session creation policy.

Game session logs. Logs are retained for all active game sessions for 14 days. To access the logs, call GetGameSessionLogUrl to download the log files.

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.

          Unique identifier for an event resource, such as a fleet ID.

        • EventCode (string) --

          Type of event being logged. The following events are currently in use:

          Fleet creation events:

          • FLEET_CREATED -- A fleet record was successfully created with a status of NEW . Event messaging includes the fleet ID.

          • FLEET_STATE_DOWNLOADING -- Fleet status changed from NEW to DOWNLOADING . The compressed build has started downloading to a fleet instance for installation.

          • FLEET_BINARY_DOWNLOAD_FAILED -- The build failed to download to the fleet instance.

          • FLEET_CREATION_EXTRACTING_BUILD – The game server build was successfully downloaded to an instance, and the build files are now being extracted from the uploaded build and saved to an instance. Failure at this stage prevents a fleet from moving to ACTIVE status. Logs for this stage display a list of the files that are extracted and saved on the instance. Access the logs by using the URL in PreSignedLogUrl .

          • FLEET_CREATION_RUNNING_INSTALLER – The game server build files were successfully extracted, and the Amazon GameLift is now running the build's install script (if one is included). Failure in this stage prevents a fleet from moving to ACTIVE status. Logs for this stage list the installation steps and whether or not the install completed successfully. Access the logs by using the URL in PreSignedLogUrl .

          • FLEET_CREATION_VALIDATING_RUNTIME_CONFIG -- The build process was successful, and the Amazon GameLift is now verifying that the game server launch paths, which are specified in the fleet's run-time configuration, exist. If any listed launch path exists, Amazon GameLift tries to launch a game server process and waits for the process to report ready. Failures in this stage prevent a fleet from moving to ACTIVE status. Logs for this stage list the launch paths in the run-time configuration and indicate whether each is found. Access the logs by using the URL in PreSignedLogUrl .

          • FLEET_STATE_VALIDATING -- Fleet status changed from DOWNLOADING to VALIDATING .

          • FLEET_VALIDATION_LAUNCH_PATH_NOT_FOUND -- Validation of the run-time configuration failed because the executable specified in a launch path does not exist on the instance.

          • FLEET_STATE_BUILDING -- Fleet status changed from VALIDATING to BUILDING .

          • FLEET_VALIDATION_EXECUTABLE_RUNTIME_FAILURE -- Validation of the run-time configuration failed because the executable specified in a launch path failed to run on the fleet instance.

          • FLEET_STATE_ACTIVATING -- Fleet status changed from BUILDING to ACTIVATING .

          • FLEET_ACTIVATION_FAILED - The fleet failed to successfully complete one of the steps in the fleet activation process. This event code indicates that the game build was successfully downloaded to a fleet instance, built, and validated, but was not able to start a server process. A possible reason for failure is that the game server is not reporting "process ready" to the Amazon GameLift service.

          • FLEET_STATE_ACTIVE -- The fleet's status changed from ACTIVATING to ACTIVE . The fleet is now ready to host game sessions.

          VPC peering events:

          • FLEET_VPC_PEERING_SUCCEEDED -- A VPC peering connection has been established between the VPC for an Amazon GameLift fleet and a VPC in your AWS account.

          • FLEET_VPC_PEERING_FAILED -- A requested VPC peering connection has failed. Event details and status information (see DescribeVpcPeeringConnections ) provide additional detail. A common reason for peering failure is that the two VPCs have overlapping CIDR blocks of IPv4 addresses. To resolve this, change the CIDR block for the VPC in your AWS account. For more information on VPC peering failures, see http://docs.aws.amazon.com/AmazonVPC/latest/PeeringGuide/invalid-peering-configurations.html

          • FLEET_VPC_PEERING_DELETED -- A VPC peering connection has been successfully deleted.

          Spot instance events:

          • INSTANCE_INTERRUPTED -- A spot instance was interrupted by EC2 with a two-minute notification.

          Other fleet events:

          • FLEET_SCALING_EVENT -- A change was made to the fleet's capacity settings (desired instances, minimum/maximum scaling limits). Event messaging includes the new capacity settings.

          • FLEET_NEW_GAME_SESSION_PROTECTION_POLICY_UPDATED -- A change was made to the fleet's game session protection policy setting. Event messaging includes both the old and new policy setting.

          • FLEET_DELETED -- A request to delete a fleet was initiated.

          • GENERIC_EVENT -- An unspecified event has occurred.

        • Message (string) --

          Additional information related to the event.

        • EventTime (datetime) --

          Time stamp indicating when this event occurred. Format is a number expressed in Unix time as milliseconds (for example "1469498468.057").

        • PreSignedLogUrl (string) --

          Location of stored logs with additional detail that is related to the event. This is useful for debugging issues. The URL is valid for 15 minutes. You can also access fleet creation logs through the Amazon GameLift console.

    • NextToken (string) --

      Token that indicates where to resume retrieving results on the next call to this action. If no token is returned, these results represent the end of the list.

DescribeGameSessionDetails (updated) Link ¶
Changes (response)
{'GameSessionDetails': {'GameSession': {'StatusReason': 'INTERRUPTED'}}}

Retrieves properties, including the protection policy in force, for one or more game sessions. This action can be used in several ways: (1) provide a GameSessionId or GameSessionArn to request details for a specific game session; (2) provide either a FleetId or an AliasId to request properties for all game sessions running on a fleet.

To get game session record(s), specify just one of the following: game session ID, fleet ID, or alias ID. You can filter this request by game session status. Use the pagination parameters to retrieve results as a set of sequential pages. If successful, a GameSessionDetail object is returned for each session matching the request.

SearchGameSessions (updated) Link ¶
Changes (response)
{'GameSessions': {'StatusReason': 'INTERRUPTED'}}

Retrieves all active game sessions that match a set of search criteria and sorts them in a specified order. You can search or sort by the following game session attributes:

  • gameSessionId -- Unique identifier for the game session. You can use either a GameSessionId or GameSessionArn value.

  • gameSessionName -- Name assigned to a game session. This value is set when requesting a new game session with CreateGameSession or updating with UpdateGameSession. Game session names do not need to be unique to a game session.

  • gameSessionProperties -- Custom data defined in a game session's GameProperty parameter. GameProperty values are stored as key:value pairs; the filter expression must indicate the key and a string to search the data values for. For example, to search for game sessions with custom data containing the key:value pair "gameMode:brawl", specify the following: gameSessionProperties.gameMode = "brawl". All custom data values are searched as strings.

  • maximumSessions -- Maximum number of player sessions allowed for a game session. This value is set when requesting a new game session with CreateGameSession or updating with UpdateGameSession.

  • creationTimeMillis -- Value indicating when a game session was created. It is expressed in Unix time as milliseconds.

  • playerSessionCount -- Number of players currently connected to a game session. This value changes rapidly as players join the session or drop out.

  • hasAvailablePlayerSessions -- Boolean value indicating whether a game session has reached its maximum number of players. It is highly recommended that all search requests include this filter attribute to optimize search performance and return only sessions that players can join.

Note

Returned values for playerSessionCount and hasAvailablePlayerSessions change quickly as players join sessions and others drop out. Results should be considered a snapshot in time. Be sure to refresh search results often, and handle sessions that fill up before a player can join.

To search or sort, specify either a fleet ID or an alias ID, and provide a search filter expression, a sort expression, or both. If successful, a collection of GameSession objects matching the request is returned. Use the pagination parameters to retrieve results as a set of sequential pages.

You can search for game sessions one fleet at a time only. To find game sessions across multiple fleets, you must search each fleet separately and combine the results. This search feature finds only game sessions that are in ACTIVE status. To locate games in statuses other than active, use DescribeGameSessionDetails.

    FilterExpression='string',
    SortExpression='string',
    Limit=123,
    NextToken='string'
)
type FleetId

string

param FleetId

Unique identifier for a fleet to search for active game sessions. Each request must reference either a fleet ID or alias ID, but not both.

type AliasId

string

param AliasId

Unique identifier for an alias associated with the fleet to search for active game sessions. Each request must reference either a fleet ID or alias ID, but not both.

type FilterExpression

string

param FilterExpression

String containing the search criteria for the session search. If no filter expression is included, the request returns results for all game sessions in the fleet that are in ACTIVE status.

A filter expression can contain one or multiple conditions. Each condition consists of the following:

  • Operand -- Name of a game session attribute. Valid values are gameSessionName , gameSessionId , gameSessionProperties , maximumSessions , creationTimeMillis , playerSessionCount , hasAvailablePlayerSessions .

  • Comparator -- Valid comparators are: = , <> , < , > , <= , >= .

  • Value -- Value to be searched for. Values may be numbers, boolean values (true/false) or strings depending on the operand. String values are case sensitive and must be enclosed in single quotes. Special characters must be escaped. Boolean and string values can only be used with the comparators = and <> . For example, the following filter expression searches on gameSessionName : " FilterExpression": "gameSessionName = 'Matt\\'s Awesome Game 1'" .

To chain multiple conditions in a single expression, use the logical keywords AND , OR , and NOT and parentheses as needed. For example: x AND y AND NOT z , NOT (x OR y) .

Session search evaluates conditions from left to right using the following precedence rules:

  • = , <> , < , > , <= , >=

  • Parentheses

  • NOT

  • AND

  • OR

For example, this filter expression retrieves game sessions hosting at least ten players that have an open player slot: "maximumSessions>=10 AND hasAvailablePlayerSessions=true" .

type SortExpression

string

param SortExpression

Instructions on how to sort the search results. If no sort expression is included, the request returns results in random order. A sort expression consists of the following elements:

  • Operand -- Name of a game session attribute. Valid values are gameSessionName , gameSessionId , gameSessionProperties , maximumSessions , creationTimeMillis , playerSessionCount , hasAvailablePlayerSessions .

  • Order -- Valid sort orders are ASC (ascending) and DESC (descending).

For example, this sort expression returns the oldest active sessions first: "SortExpression": "creationTimeMillis ASC" . Results with a null value for the sort operand are returned at the end of the list.

type Limit

integer

param Limit

Maximum number of results to return. Use this parameter with NextToken to get results as a set of sequential pages. The maximum number of results returned is 20, even if this value is not set or is set higher than 20.

type NextToken

string

param NextToken

Token that indicates the start of the next sequential page of results. Use the token that is returned with a previous call to this action. To start at the beginning of the result set, do not specify a value.
