Question

我正在编写一个 tf 脚本来创建一个角色并将 AWS 托管策略附加到该角色。如果我的策略是自定义策略，这有效，如果我需要使用 AWS 托管策略，我如何将我的策略附加到角色。有没有办法使用“数据”从 AWS 推断角色 ARN

resource "aws_iam_role" "CloudWatchAgentServerRole" {
  name               = "CloudWatchAgentServerRole"
  description        = "Role created to allow Memory metrics to CloudWatch "
  assume_role_policy = file("role.json")
}

#Create Policy - Not Required as its an AWS Managed Policy
/*resource "aws_iam_policy" "CloudWatchAgentServerPolicy" {
  name        = "CloudWatchAgentServerPolicy"
  description = "Permissions required to use AmazonCloudWatchAgent on servers"
  policy      = file("policy.json")
}*/

# Attach Policy 
resource "aws_iam_role_policy_attachment" "CloudWatchAgentServer" {
  role       = aws_iam_role.CloudWatchAgentServerRole.name
  policy_arn = aws_iam_policy.CloudWatchAgentServerPolicy.arn  
}

谢谢

AWS 托管策略的 ARN 将是 arn:aws:iam::aws:policy/，后跟策略名称。确实没有必要使用 data 元素查找它，因为它始终采用该格式。因此，要在您的示例中附加策略，您将使用以下内容：

resource "aws_iam_role_policy_attachment" "CloudWatchAgentServer" {
  role       = aws_iam_role.CloudWatchAgentServerRole.name
  policy_arn = "arn:aws:iam::aws:policy/CloudWatchAgentServerPolicy"
}

通过 Terraform 将 AWS 托管策略附加到自定义角色
