Terraform aws_spot_fleet_request iam_instance_profile

Question

我阅读了来自here的Terraform spot舰队示例用法。

"iam_instance_profile_arn“的意义是什么?它在示例1中的作用是什么？

我在某些情况下收到错误"launch_specification.0: invalid or unknown key: tags“，而在其他情况下却没有，所以我认为这可能与iam_profile有关。

iam_instance_profile_arn  = "${aws_iam_instance_profile.example.arn}"

示例1：

# Request a Spot fleet
resource "aws_spot_fleet_request" "cheap_compute" {
  iam_fleet_role      = "arn:aws:iam::12345678:role/spot-fleet"
  spot_price          = "0.03"
  allocation_strategy = "diversified"
  target_capacity     = 6
  valid_until         = "2019-11-04T20:44:20Z"

  launch_specification {
    instance_type             = "m4.10xlarge"
    ami                       = "ami-1234"
    spot_price                = "2.793"
    placement_tenancy         = "dedicated"
    iam_instance_profile_arn  = "${aws_iam_instance_profile.example.arn}"
  }

  launch_specification {
    instance_type             = "m4.4xlarge"
    ami                       = "ami-5678"
    key_name                  = "my-key"
    spot_price                = "1.117"
    iam_instance_profile_arn  = "${aws_iam_instance_profile.example.arn}"
    availability_zone         = "us-west-1a"
    subnet_id                 = "subnet-1234"
    weighted_capacity         = 35

    root_block_device {
      volume_size = "300"
      volume_type = "gp2"
    }

    tags {
      Name = "spot-fleet-example"
    }
  }
}

示例2：

resource "aws_spot_fleet_request" "foo" {
  iam_fleet_role  = "arn:aws:iam::12345678:role/spot-fleet"
  spot_price      = "0.005"
  target_capacity = 2
  valid_until     = "2019-11-04T20:44:20Z"

  launch_specification {
    instance_type     = "m1.small"
    ami               = "ami-d06a90b0"
    key_name          = "my-key"
    availability_zone = "us-west-2a"
  }

  launch_specification {
    instance_type     = "m3.large"
    ami               = "ami-d06a90b0"
    key_name          = "my-key"
    availability_zone = "us-west-2a"
  }

  depends_on = ["aws_iam_policy_attachment.test-attach"]
}

Answer 1

实例配置文件与错误无关。错误是这样说的：

tags {
       Name = "spot-fleet-example"
     }

第一个示例的一部分无法识别。您可以了解哪些实例配置文件是here

实例配置文件是IAM角色的容器，您可以使用该容器在EC2实例启动时将角色信息传递给该实例。
