[英]How to transfer a powershell list variable to terraform by using Azure Devops?
I have a list which is filled with addressprefixes like 192.168.1.0/24我有一个列表,其中充满了地址前缀,如192.168.1.0/24
$listOfSubnetsToBeCreated = @()
Write-Host "##vso[task.setvariable variable=availableSubnetList]$listOfSubnetsToBeCreated"
created in a powershell and transferred to azure devops pipeline variable that i have already defined in Azure Devops.在 powershell 中创建并转移到我已经在 Azure Devops 中定义的 azure devops 管道变量。
I am using this variable which is set on the run with
我正在使用这个在运行时设置的变量
terraform apply -var="availableSubnetList=$(availableSubnetList)"
in my Terraform task to create a subnet.在我的 Terraform 任务中创建子网。 Here below is the tf script:
下面是 tf 脚本:
variable "availableSubnetList" {
type = list(string)
default = [""]
}
resource "azurerm_subnet" "Subnet-lab" {
count = var.project_subnet_number
name = join("-", ["${var.LabRGName}","subnet", "${count.index + 1}"])
resource_group_name = var.AdminRGName
virtual_network_name = var.lab_vnet
address_prefix = var.availableSubnetList[count.index]
}
When i executed the pipeline, i am having the following error on terraform apply task:当我执行管道时,在terraform 应用任务上出现以下错误:

Afaik, the variables in Azure Devops are strings. Afaik,Azure Devops 中的变量是字符串。 Do you have any idea on how to transfer a powershell list correctly to terraform by using Azure Devops?
您对如何使用 Azure Devops 将 powershell 列表正确传输到 terraform 有任何想法吗?
Output a comma-separated string of subnets from the PowerShell script: Output 来自 PowerShell 脚本的以逗号分隔的子网字符串:
Write-Host "##vso[task.setvariable variable=availableSubnetList]$($listOfSubnetsToBeCreated -join ',')"
Then split it into a list again when invoking terraform:然后在调用 terraform 时再次拆分成一个列表:
terraform apply -var='availableSubnetList=${split(",", $(availableSubnetList))}'
Or change the way you resolve each subnet in terraform:或者更改您在 terraform 中解析每个子网的方式:
address_prefix = split(",", var.availableSubnetList)[count.index]
