IAM permission examples for Amazon GameLift Servers

Use the syntax in these examples to set Amazon Identity and Access Management (IAM) permissions for users that need access to Amazon GameLift Servers resources.

Example Syntax for Amazon GameLift Servers resource and PassRole permissions

  "Version": "2012-10-17",
  "Statement": [
