尝试为AWS KMS编写Terraform代码

Question

  

目标：

     

    

我正在尝试创建以下东西A terraform模板     创建KMS密钥此模板应创建密钥和两个IAM角色。     这些角色将是一个用于管理功能和一个允许的角色     加密/解密我写了以下代码

  

我是否正确地实现了我的目标？

provider "aws"
{
access_key = "*****************"
secret_key = "4ZJaLh***********"
region     = "us-east-1"
}

resource "aws_kms_key" "test_key" {
  description             = "KMS Test key"
}

resource "aws_kms_alias" "alias" {
  name          = "alias/test_key"
  target_key_id = "${aws_kms_key.test_key.key_id}"
}

#IAM Role and Policy

resource "aws_iam_policy" "kms_user_policy" {
    name = "KMS-User-Policy"
    policy = <<EOF
{
    "Version": "2012-10-17",
    "Statement": [
        {

            ],
            "Resource": "*"
        }
    ]
}
