无法通过Terraform提供AWS_SPOT_INSTANCE

Question

我试图通过Terraform旋转一个点实例。当我尝试使用Provisioner Block（"远程证明"或"文件"）时，它会失败，并且在调试级别输出中看到SSH错误。当我从点实例请求切换到标准AWS实例资源声明时，该配置正常。

代码无法正常工作：

    resource "aws_spot_instance_request" "worker01" {
      ami           = "ami-0cb95574"
      spot_price    = "0.02"
      instance_type = "m3.medium"
      vpc_security_group_ids = [ "${aws_security_group.ssh_access.id}", "${aws_security_group.tcp_internal_access.id}","${aws_security_group.splunk_access.id}","${aws_security_group.internet_access.id}" ]
      subnet_id     = "..."
      associate_public_ip_address = true
      connection {
        type = "ssh"
        user = "ec2-user"
        private_key = "${file("${var.private_key_path}")}"
      }
       provisioner "remote-exec" {
         inline = [
           "touch foo",
         ]
       }
    }

错误：

    aws_spot_instance_request.worker01 (remote-exec): Connecting to remote host via SSH...
    aws_spot_instance_request.worker01 (remote-exec):   Host:
    aws_spot_instance_request.worker01 (remote-exec):   User: ec2-user

工作代码：

    resource "aws_instance" "worker01" {
      ami           = "ami-0cb95574"
      instance_type = "m3.medium"
      vpc_security_group_ids = [ "${aws_security_group.ssh_access.id}", "${aws_security_group.tcp_internal_access.id}","${aws_security_group.splunk_access.id}","${aws_security_group.internet_access.id}" ]
      subnet_id     = "..."
      associate_public_ip_address = true
      connection {
        type = "ssh"
        user = "ec2-user"
        private_key = "${file("${var.private_key_path}")}"
      }
       provisioner "remote-exec" {
         inline = [
           "touch foo",
         ]
       }
    }

我尝试过一些非工作代码的不同迭代（包括愚蠢的尝试将公共IP备用公共IP进行点现场实例，并尝试对现场实例进行自我参考 - 这给出了没有这样的实例属性错误）。不幸的是，我找不到通过Google有类似问题的人。从我阅读的内容来看，我应该能够以这种方式提供一个点实例。

感谢您提供的任何帮助。

您需要将wait_for_fulfillment = true添加到您的点实例请求中，否则资源将在创建实例之前返回。
