通过环境变量文件 .tfvars 在 Terraform 中 variables.tf 中提到的变量的值 [英] Values to variables mentioned in variables.tf in Terraform through environment variables file .tfvars

问题描述

如何传递 variable.tf 中提到的 "list" 或 "map" 类型的变量的值.下面提到的 input.tfvars 文件中的语法是否有错误?

How do I pass the values of variables mentioned in variable.tf of type "list" or "map" . Are there any mistakes in the syntax in the input.tfvars file mentioned below?

目标不是硬编码 variables.tf 或 main.tf 文件中的任何值.在 Terraform.io 文档中，我验证了可以以这种格式提供值.

The goal is not to hard code any values in the variables.tf or the main.tf file. In the Terraform.io docs I verified that the values can be provided in this format.

这是来自网站:
列表可以显式或隐式定义:

This is from the site:
Lists are defined either explicitly or implicitly:

 # implicitly by using brackets [...]
 variable "cidrs" { default = [] }

 # explicitly
 variable "cidrs" { type = "list" }

您可以在 terraform.tfvars 文件中指定列表:

You can specify lists in a the terraform.tfvars file:

 cidrs = [ "10.0.0.0/16", "10.1.0.0/16" ]

现在，当我尝试这样做时

Now, when I try to do

terraform plan -var-file=input.tfvars 

无法从 tfvars 文件中读取变量值并出现以下错误:

it is unable to read the variable values from the tfvars file and presents the following error:

错误:模块根目录:
模块 vpc:未设置所需变量vpccidr"
模块 vpc:未设置所需变量vpcname"

Error: module root:
module vpc: required variable "vpccidr" not set
module vpc: required variable "vpcname" not set

variables.tf 文件如下所示:

variable "vpccidr" { type = "list"}
variable "vpcname" { type = "list" }

input.tfvars 文件如下所示:

vpccidr=[ "10.1.0.0/16", "10.2.0.0/16", "10.3.0.0/16" ]
vpcname=[ "vpc1", "vpc2", "vpc3" ]

main.tf 文件如下所示:

module "vpc"{
  source = "modules/network/vpc"
}

modules/network下的VPC模块有如下配置文件main.tf和上面提到的variables.tf变量文件:

The VPC module under modules/network has the following configuration file main.tf and the variable file mentioned above in variables.tf:

resource "aws_vpc" "customVpc" {
  count = "${length(var.vpccidr)}"
  cidr_block = "${element(var.vpccidr, count.index)}"
  tags {
    count = "${length(var.vpcname)}"
    Name = "${element(var.vpcname, count.index)}"
  }
}          

推荐答案

您需要将变量传递给您的模块，即

You need to pass the variables to your module, i.e

module "vpc"{
  source = "modules/network/vpc"

  vpccidr = "${var.vpccidr}"
  vpcname = "${var.vpcname}"
}
