CreateFleet

Creates a fleet of compute resources to host your game servers. Use this operation to set up the following types of fleets based on compute type:

Managed EC2 fleet

An EC2 fleet is a set of Amazon Elastic Compute Cloud (Amazon EC2) instances. Your game server build is deployed to each fleet instance. Amazon GameLift manages the fleet's instances and controls the lifecycle of game server processes, which host game sessions for players. EC2 fleets can have instances in multiple locations. Each instance in the fleet is designated a Compute.

To create an EC2 fleet, provide these required parameters:

If successful, this operation creates a new fleet resource and places it in NEW status while Amazon GameLift initiates the fleet creation workflow. To debug your fleet, fetch logs, view performance metrics or other actions on the fleet, create a development fleet with port 22/3389 open. As a best practice, we recommend opening ports for remote access only when you need them and closing them when you're finished.

When the fleet status is ACTIVE, you can adjust capacity settings and turn autoscaling on/off for each location.

Anywhere fleet

An Anywhere fleet represents compute resources that are not owned or managed by Amazon GameLift. You might create an Anywhere fleet with your local machine for testing, or use one to host game servers with on-premises hardware or other game hosting solutions.

To create an Anywhere fleet, provide these required parameters:

If successful, this operation creates a new fleet resource and places it in ACTIVE status. You can register computes with a fleet in ACTIVE status.

Examples

Create fleet with minimal configuration

This example creates an EC2 fleet for a game server build with a minimal configuration and a placeholder launch path. You can use this fleet to create queues and matchmakers, test Amazon GameLift Server API calls, etc. When you're ready to start hosting game sessions, complete the configuration settings using the UpdateFleet operations. If the fleet is in a Region that supports multiple locations, you can add remote locations with CreateFleetLocations later. Note: this example generates a TLS certificate for the fleet, which can only be enabled during fleet creation.

Create fleet with full configuration

This example creates an EC2 fleet with complete configuration details. The new fleet, which is created in the AWS Region us-west-2, also deploys instances to two remote locations. In this example, the runtime configuration defines two server process configurations. The first configuration calls for three concurrent processes of the game server to run in standard mode. The second configuration calls for one process of the game server to run in a test mode. As a result, all fleet instances will maintain a total of four processes concurrently. This example also references an instance role ARN, which allows the processes running on each instance to access other AWS resources. The example opens port 22 for debugging the fleet. The game server build in this example runs on Windows.

Create a Realtime Servers fleet

This example creates a fleet using a Realtime script that has been uploaded to Amazon GameLift. All Realtime servers are deployed onto Linux machines. This example represents a simple yet complete fleet configuration. You can change configuration settings with the UpdateRuntimeConfiguration operation. The new fleet, which is created in the AWS Region us-west-2, also deploys instances to two remote locations.

In this example, the uploaded Realtime script includes multiple script files, with the Init() function located in the script file called "myMainScript.js". This file is identified as the launch script in the runtime configuration.
