Terraform

Question

背景

Terraform 文档明确指出根模块中定义的变量可以在 tfvars 文件中设置。

The type constructors allow you to specify complex types such as collections:

set(<TYPE>)

Assigning Values to Root Module Variables

When variables are declared in the root module of your configuration, they can be set in a number of ways:

In variable definitions (.tfvars) files, either specified on the command line or automatically loaded.

可以在根模块中定义 set 类型的输入变量。

variables.tf

variable "roles" {
  description = "IAM roles to grant to the service account"
  type    = set(string)
}

问题

请指教如何初始化tfvars中的set变量？不允许使用函数，据我环顾四周，Terraform 文档中似乎没有示例。或者如果设置 set 不受支持，是否明确记录？

terraform.tfvars

roles = toset([
  "roles/cloudsql.client",
  "roles/bigquery.dataEditor",
  "roles/storage.admin",
  "roles/pubsub.edito",
  "roles/secretmanager.secretAccessor",
  "roles/artifactregistry.reader"
])

Answer 1

您只需将其定义为：

roles = [
  "roles/cloudsql.client",
  "roles/bigquery.dataEditor",
  "roles/storage.admin",
  "roles/pubsub.edito",
  "roles/secretmanager.secretAccessor",
  "roles/artifactregistry.reader"
]

TF 会自动将其转换为正确的类型。
