使用 terraform 版本 13 时，我收到错误“区域参数中的变量的默认值无效”，如何解决？

Question

变量.tf

variable "region" {
  default = "us-central1"
}

variable "zone" {
  description = "override default zone specified in region_params"
  default     = ""
}

variable "region_params" {
  description = "Map of default zones for each region. Can be overridden using the `zone`."
  type        = map(string)

  default = {
    asia-east1 = {
      zone = "asia-east1-b"
    }
    asia-east2 = {
      zone = "asia-east2-b"
    }

}

variable "network" {
}

variable "instance_tags" {
  default = []
}

variable "ip_cidr_range" {
  description = "Subnetwork range - required"
}

variable "environment" {
  description = "The build environment tier"
  default     = "dev"
}

output "nat-gateway-ip" {
  value = module.nat.external_ip
}

./terraform0.13 init-重新配置

There are some problems with the configuration, described below.

The Terraform configuration must be valid before initialization so that
Terraform can determine which modules and providers need to be installed.

Answer 1

尝试将其设置为 us-central-1。您的区域格式错误，数字前需要加一个破折号。此外，您不需要指定 a、b 或 c，因为 terraform 会从您的子网设置中获取信息。
