如何在 terraform 中正确使用 for_each 中的 each.value? [英] How to correctly use each.value in for_each in terraform?

问题描述

我正在尝试为每个用户创建一个文件，并将分配给他们的项目作为文件的内容.我很高兴得到${each.value}"；因为它是一个字符串列表.请问有什么办法吗?

I am trying to create a files for each user with the projects assigned to them as content of the file. I amunable to get the "${each.value}" as it is a list of strings. Any way around this please?

locals {
  data = {
    "project1" = {
      user_assigned           = ["user1", "user2", "user3"]
     }
    "project2" = {
      user_assigned           = ["user2", "user3", "user4"]
     }
  }


`
resource "local_file" "foo" {
  for_each = transpose(zipmap(keys(local.data), values(local.data)[*].user_assigned))
  content  = "${each.value}"
  filename = "${each.key}"
}

错误:

  on test.tf line 85, in resource "local_file" "foo":
  85:   content  = "${each.value}"
    |----------------
    | each.value is list of string with 2 elements

推荐答案

content 必须是字符串，但在你的情况下它是一个列表，例如[project1"、project2"].将其转换为字符串的一种方法是通过 jsonencode:

The content must be string, but in your case it is a list, e.g. ["project1", "project2"]. One way to convert it to string is through jsonencode:

resource "local_file" "foo" {
  for_each = transpose(zipmap(keys(local.data), values(local.data)[*].user_assigned))
  content  = jsonencode(each.value)
  filename = each.key
}
