Packer ec2-ami部署上的标记格式

Question

我正在尝试第一次使用Hashicorp创建一个amazon，但是在创建标记时遇到了这个失败，我已经尝试了一些格式的尝试和错误测试，但是仍然是不吉利的。

[ec2-boy-oh-boy@ip-172-168-99-23 pogi]$ packer init .
Error: Missing item separator

  on variables.pkr.hcl line 28, in variable "tags":
  27:   default = [
  28:    "environment"    : "testing"

Expected a comma to mark the beginning of the next item. 

我的代码ec2.pkr.hcl如下所示：

[ec2-boy-oh-boy@ip-172-168-99-23 pogi]$ cat ec2.pkr.hcl 
packer {
  required_plugins {
    amazon = {
      version = ">= 0.0.2"
      source  = "github.com/hashicorp/amazon"
    }
  }
}

source "amazon-ebs" "ec2" {
  ami_name      = "${var.ami_prefix}-${local.timestamp}"
  instance_type = "t2.micro"
  region        = "us-east-1"
  vpc_id        = "${var.vpc}"
  subnet_id     = "${var.subnet}"
  security_group_ids = ["${var.sg}"]
  ssh_username = "ec2-boy-oh-boy"
  source_ami_filter {
    filters = {
      name                = "amzn2-ami-hvm-2.0*"
      root-device-type    = "ebs"
      virtualization-type = "hvm"
    }
    most_recent = true
    owners      = ["12345567896"]
  }
  launch_block_device_mappings = [
    {
        "device_name": "/dev/xvda",
        "delete_on_termination": true
        "volume_size": 10
        "volume_type": "gp2"
    }
   ]
  run_tags = "${var.tags}"
  run_volume_tags = "${var.tags}"
}

build {
  sources = [
    "source.amazon-ebs.ec2"
  ]
}
[ec2-boy-oh-boy@ip-172-168-99-23 pogi]$ 

然后我的代码variables.pkr.hcl如下所示：

 [ec2-boy-oh-boy@ip-172-168-99-23 pogi]$ cat variables.pkr.hcl 
locals {
  timestamp = regex_replace(timestamp(), "[- TZ:]", "")
}

variable "ami_prefix" {
  type    = string
  default = "ec2-boy-oh-boy"
}

variable "vpc" {
  type    = string
  default = "vpc-asd957d"
}

variable "subnet" {
  type    = string
  default = "subnet-asd957d"
}

variable "sg" {
  type    = string
  default = "sg-asd957d"
}

variable "tags" {
  type = map
  default = [
    environment        = "testing"
    type               = "none"
    production         = "later"
  ]
}

Answer 1

tags变量的默认值为list(string)类型。标签和标签指令都期望类型为map[string]string。

我对变量文件进行了以下更改，并成功地运行了packer init：

variable "tags" {
  default = {
    environment = "testing"
    type        = "none"
    production  = "later"
  }

  type = map(string)
}
