无法通过 terraform 配置 aws_spot_instance

Question

我正在尝试通过 terraform 启动一个现货实例。当我尝试使用配置程序块（“remote-exec”或“file”）时，它失败，并且我在调试级别输出中看到 SSH 错误。当我从 Spot 实例请求切换到标准 aws 实例资源声明时，配置工作正常。

代码不起作用：

    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",
         ]
       }
    }

我尝试了非工作代码的一些不同迭代（包括愚蠢地尝试对现货实例的公共 IP 进行硬编码，以及尝试对现货实例公共 IP 进行自引用 - 这给出了 no such attribute 错误） 。不幸的是，我无法通过谷歌找到有类似问题的人。根据我所读到的内容，我应该能够以这种方式提供一个现货实例。

感谢您的任何帮助，您可以提供。

您需要添加wait_for_fulfillment = true到您的竞价实例请求中，否则资源将在创建实例之前返回。
