Amazon GameLift examples using Amazon CLI

The following code examples show you how to perform actions and implement common scenarios by using the Amazon Command Line Interface with Amazon GameLift.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios and cross-service examples.

Scenarios are code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

Each example includes a link to GitHub, where you can find instructions on how to set up and run the code in context.

The following code example shows how to use create-build.

Amazon CLI

Example1: To create a game build from files in an S3 bucket

The following create-build example creates a custom game build resource. It uses zipped files that are stored in an S3 location in an Amazon account that you control. This example assumes that you've already created an IAM role that gives Amazon GameLift permission to access the S3 location. Since the request does not specify an operating system, the new build resource defaults to WINDOWS_2012.

aws gamelift create-build \ --storage-location file://storage-loc.json \ --name MegaFrogRaceServer.NA \ --build-version 12345.678

Contents of storage-loc.json:

{ "Bucket":"MegaFrogRaceServer_NA_build_files" "Key":"MegaFrogRaceServer_build_123.zip" "RoleArn":"arn:aws:iam::123456789012:role/gamelift" }

Output:

{ "Build": { "BuildArn": "arn:aws:gamelift:us-west-2::build/build-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111", "BuildId": "build-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111", "CreationTime": 1496708916.18, "Name": "MegaFrogRaceServer.NA", "OperatingSystem": "WINDOWS_2012", "SizeOnDisk": 479303, "Status": "INITIALIZED", "Version": "12345.678" }, "StorageLocation": { "Bucket": "MegaFrogRaceServer_NA_build_files", "Key": "MegaFrogRaceServer_build_123.zip" } }

Example2: To create a game build resource for manually uploading files to GameLift

The following create-build example creates a new build resource. It also gets a storage location and temporary credentials that allow you to manually upload your game build to the GameLift location in Amazon S3. Once you've successfully uploaded your build, the GameLift service validates the build and updates the new build's status.

aws gamelift create-build \ --name MegaFrogRaceServer.NA \ --build-version 12345.678 \ --operating-system AMAZON_LINUX

Output:

{ "Build": { "BuildArn": "arn:aws:gamelift:us-west-2::build/build-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111", "BuildId": "build-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111", "CreationTime": 1496708916.18, "Name": "MegaFrogRaceServer.NA", "OperatingSystem": "AMAZON_LINUX", "SizeOnDisk": 0, "Status": "INITIALIZED", "Version": "12345.678" }, "StorageLocation": { "Bucket": "gamelift-builds-us-west-2", "Key": "123456789012/build-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111" }, "UploadCredentials": { "AccessKeyId": "AKIAIOSFODNN7EXAMPLE", "SecretAccessKey": "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY", "SessionToken": "AgoGb3JpZ2luENz...EXAMPLETOKEN==" } }

The following code example shows how to use create-game-session-queue.

Amazon CLI

Example1: To set up an ordered game session queue

The following create-game-session-queue example creates a new game session queue with destinations in two regions. It also configures the queue so that game session requests time out after waiting 10 minutes for placement. Since no latency policies are defined, GameLift attempts to place all game sessions with the first destination listed.

aws gamelift create-game-session-queue \ --name MegaFrogRaceServer-NA \ --destinations file://destinations.json \ --timeout-in-seconds 600

Contents of destinations.json:

{ "Destinations": [ {"DestinationArn": "arn:aws:gamelift:us-west-2::fleet/fleet-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111" }, {"DestinationArn": "arn:aws:gamelift:us-west-1::fleet/fleet-a1b2c3d4-5678-90ab-cdef-EXAMPLE22222" } ] }

Output:

{ "GameSessionQueues": [ { "Name": "MegaFrogRaceServer-NA", "GameSessionQueueArn": "arn:aws:gamelift:us-west-2:123456789012:gamesessionqueue/MegaFrogRaceServer-NA", "TimeoutInSeconds": 600, "Destinations": [ {"DestinationArn": "arn:aws:gamelift:us-west-2::fleet/fleet-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111"}, {"DestinationArn": "arn:aws:gamelift:us-west-1::fleet/fleet-a1b2c3d4-5678-90ab-cdef-EXAMPLE22222"} ] } ] }

Example2: To set up a game session queue with player latency policies

The following create-game-session-queue example creates a new game session queue with two player latency policies. The first policy sets a 100ms latency cap that is enforced during the first minute of a game session placement attempt. The second policy raises the latency cap to 200ms until the placement request times out at 3 minutes.

aws gamelift create-game-session-queue \ --name MegaFrogRaceServer-NA \ --destinations file://destinations.json \ --player-latency-policies file://latency-policies.json \ --timeout-in-seconds 180

Contents of destinations.json:

{ "Destinations": [ { "DestinationArn": "arn:aws:gamelift:us-west-2::fleet/fleet-a1b2c3d4-5678-90ab-cdef-EXAMPLE11111" }, { "DestinationArn": "arn:aws:gamelift:us-east-1::fleet/fleet-a1b2c3d4-5678-90ab-cdef-EXAMPLE22222" } ] }

Contents of latency-policies.json:

{ "PlayerLatencyPolicies": [ {"MaximumIndividualPlayerLatencyMilliseconds": 200}, {"MaximumIndividualPlayerLatencyMilliseconds": 100, "PolicyDurationSeconds": 60} ] }
