无法将 AWS 策略应用于组，只能应用于用户

Question

我正在尝试在 CloudSearch 域上设置权限。

此政策有效：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::55555555:user/SearchUser"
      },
      "Action": "cloudsearch:*"
    }
  ]
}

这不是：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::55555555:group/SearchGroup"
      },
      "Action": "cloudsearch:*"
    }
  ]
}

唯一的区别是 user/SearchUser 与 group/SearchGroup

当我尝试应用后者时，它只是给我一个错误：

Error setting policy: [{"Version":"2012-10-17","Statement":[{"Effect":"Allow","Principal":{"AWS":"arn:aws:iam::55555555:group/SearchGroup"},"Action":"cloudsearch:*"}]}]

关于为什么该策略适用于用户而不适用于组的任何想法？

Answer 1

不支持群组。

Specifying a Principal

You specify a principal using the Amazon Resource Name (ARN) of the AWS account, IAM user, IAM role, federated user, or assumed-role user. You cannot specify IAM groups as principals.
