处理 for_each 中的空值并分配默认值 terraform [英] Handling empty value in for_each and assign default value terraform

问题描述

我正在创建 aws_workspace，在这个 terraform 中，我正在循环主文件中提供的变量并为每个循环分配值.但是我面临的问题是我试图将用户名仅作为第二个变量传递，现在我正在尝试 for-each 循环应该选择默认值，如果该值不是从 main.tf 文件中给出的，而是它的不工作.就像它应该选择第二个用户名并默认附加其他值

main.tf

模块aws_workspace"{source = "./modules/aws_workspace";aws_workspace = {用户 1 = {user_name = "john.doe";root_volume_encryption_enabled = 真user_volume_encryption_enabled = truevolume_encryption_key =别名/aws/工作区"；compute_type_name = "VALUE";user_volume_size_gib = 10root_volume_size_gib = 80running_mode = "AUTO_STOP";running_mode_auto_stop_timeout_in_minutes = 60},用户 2 = {用户名 = 詹姆斯"}}标签 = {名称 = 云"}bundle_id = data.aws_workspaces_bundle.value_windows_10.iddirectory_id = aws_workspaces_directory.example.id}

解决方案

你必须稍微改变你的设计，以便默认值在变量之外.例如:

<预><代码>变量aws_workspace"{默认 = {用户 1 = {user_name = "john.doe";root_volume_encryption_enabled = 真user_volume_encryption_enabled = truevolume_encryption_key =别名/aws/工作区"；compute_type_name = "VALUE";user_volume_size_gib = 10root_volume_size_gib = 80running_mode = "AUTO_STOP";running_mode_auto_stop_timeout_in_minutes = 60},用户 2 = {用户名 = 詹姆斯"}}description =aws 工作空间的配置"；}当地人{my_defaults = {root_volume_encryption_enabled = 真user_volume_encryption_enabled = truevolume_encryption_key =别名/aws/工作区"；compute_type_name = "VALUE";user_volume_size_gib = 10root_volume_size_gib = 80running_mode = "AUTO_STOP";running_mode_auto_stop_timeout_in_minutes = 60}final_aws_workspace = {对于 var.aws_workspace 中的 k,v:k＝＞合并(local.my_defaults，v)}}

然后你可以使用:

for_each = var.final_aws_workspace

I am creating aws_workspace, In this terraform I am looping over the variables provided in the main file and assigning the values using for each loop. But the issue that I am facing is that I am trying to pass the username only as a second variable and now I am trying that for-each loop should pick the default value if the value is not given from the main.tf file but its not working. like it should pick the second username and append other values by default with it

main.tf

  source        = "./modules/aws_workspace"

解决方案

You have to change your design a bit, so that default values are outside of variable. For example:

variable "aws_workspace" {
  default = {
          user1 = {
            user_name                                 = "john.doe"
            root_volume_encryption_enabled            = true
            user_volume_encryption_enabled            = true
            volume_encryption_key                     = "alias/aws/workspaces"
            compute_type_name                         = "VALUE"
            user_volume_size_gib                      = 10
            root_volume_size_gib                      = 80
            running_mode                              = "AUTO_STOP"
            running_mode_auto_stop_timeout_in_minutes = 60
        },
          user2 = {
            user_name                                 = "james"

          }
        }
  description = "configuration of aws workspaces"
}


locals {

  my_defaults =   {
      root_volume_encryption_enabled            = true
      user_volume_encryption_enabled            = true
      volume_encryption_key                     = "alias/aws/workspaces"
      compute_type_name                         = "VALUE"
      user_volume_size_gib                      = 10
      root_volume_size_gib                      = 80
      running_mode                              = "AUTO_STOP"
      running_mode_auto_stop_timeout_in_minutes = 60
  }
  
  final_aws_workspace = {for k,v in var.aws_workspace:
                            k => merge(local.my_defaults, v)
                        }

}

Then you can use :

for_each = var.final_aws_workspace
