地形。属性值不合适...需要字符串

Question

有没有办法将 Terraform 字符串列表中的每一项拆分为双引号并作为字符串输出格式？我想将这个动态变量放在 permissions 参数中。

variables.tf

variable "ext_permissions" {
  type        = list(string)
  default = ["iam.roles.list", "iam.roles.create", "iam.roles.delete"]
}

main.tf

resource "google_project_iam_custom_role" "my-custom-role" {
  role_id     = "myCustomRole"
  title       = "My Custom Role"
  description = "A description"
  permissions = ["iam.serviceAccounts.create","iam.serviceAccounts.getIamPolicy", "${var.ext_permissions}"]
}

错误：属性值类型不正确

var.ext_permissions is list of string with 2 elements Inappropriate value for attribute "permissions": element 9: string required.

AFAIS 你需要列表连接，比如

concat(["a", "b"], ["c", "d"]) -> ["a",  "b",  "c",  "d"]

或者您的情况：

permissions = concat(["iam.serviceAccounts.create","iam.serviceAccounts.getIamPolicy"], var.ext_permissions)
