Cloudformation模板為SQS創建角色

Question

我正在嘗試使用cloudformation模板創建具有嵌入式策略的角色：

{
"AWSTemplateFormatVersion": "2010-09-09",
"Resources": {
  "SQSRole": {
     "Type": "AWS::IAM::Role",
     "Properties": {
        "AssumeRolePolicyDocument": {
           "Version" : "2012-10-17",
           "Statement": [ {
              "Effect": "Allow",
              "Principal": {
                 "Service": [ "sqs.amazonaws.com" ]
              },
              "Action": [
                    "SQS:SendMessage",
                    "SQS:ReceiveMessage",
                    "SQS:DeleteMessage",
                    "SQS:GetQueueUrl"
                ]
           } ]
        },
        "Path": "/"
        }
  },
  "RootInstanceProfile": {
     "Type": "AWS::IAM::InstanceProfile",
     "Properties": {
        "Path": "/",
        "Roles": [ {
           "Ref": "SQSRole"
        } ]
     }
  }
}
}

它給出錯誤“策略中的無效主體：“ SERVICE”：“ sqs.amazonaws.com”。

我還嘗試通過替換SQS隊列的確切URL：“ SERVICE”：“ sqs.ap-south-1.amazonaws.com/710161973367/CFI-Trace”

仍然給出相同的錯誤。 不確定要為sqs指定什么服務。

如果嘗試創建要由EC2實例承擔的IAM角色，則應改用以下方法：

{
  "AWSTemplateFormatVersion": "2010-09-09",
  "Resources": {
    "SQSRole": {
      "Type": "AWS::IAM::Role",
      "Properties": {
        "AssumeRolePolicyDocument": {
          "Version": "2012-10-17",
          "Statement": [
            {
              "Effect": "Allow",
              "Principal": {
                "Service": [
                  "ec2.amazonaws.com"
                ]
              },
              "Action": [
                "sts:AssumeRole"
              ]
            }
          ]
        },
        "Path": "/",
        "Policies": [
          {
            "PolicyName": "SqsAccess",
            "PolicyDocument": {
              "Version": "2012-10-17",
              "Statement": [
                {
                  "Sid": "1",
                  "Effect": "Allow",
                  "Action": [
                    "SQS:SendMessage",
                    "SQS:ReceiveMessage",
                    "SQS:DeleteMessage",
                    "SQS:GetQueueUrl"
                  ],
                  "Resource": [
                    "*"
                  ]
                }
              ]
            }
          }
        ]
      }
    },
    "RootInstanceProfile": {
      "Type": "AWS::IAM::InstanceProfile",
      "Properties": {
        "Path": "/",
        "Roles": [
          {
            "Ref": "SQSRole"
          }
        ]
      }
    }
  }
}

請注意，現在將擔當您IAM角色的服務是ec2.amazonaws.com 。 而且，現在僅允許EC2服務承擔您的IAM角色（通過sts:AssumeRole ）。 最后，您所有的sqs:*操作已移至IAM角色的“ Policies屬性中。
