The following example creates a GameLift build named MyGameServerBuild. The build package is located in an S3 bucket, specified by the S3Bucket and S3Key input parameters. The example also creates the AWS Identity and Access Management (IAM) role that GameLift assumes so that it has permissions to download the build package files.
