无法通过terraform提供aws_spot_instance

Question

我正在尝试通过terraform旋转现场实例。当我尝试使用预配置块（“remote-exec”或“file”）时，它会失败，并在DEBUG级别输出中看到SSH错误。当我从现场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", 
     ] 
     } 
    } 

我已经尝试了非工作代码的几个不同的迭代（包括愚蠢的尝试硬编码一个现场实例的公共IP和尝试自动引用现场实例公共IP - 这没有这样的属性错误）。不幸的是，我找不到任何人通过谷歌类似的问题。从我所读到的，我应该能够以这种方式提供现场实例。

感谢您提供的任何帮助。

您需要将wait_for_fulfillment = true添加到您的专色实例请求中，否则资源将在实例创建之前返回。
