Terraform - 从提供者获取区域并在资源名称中使用它

【问题标题】：Terraform - Fetch region from provider and use it in resource nameTerraform - 从提供者获取区域并在资源名称中使用它
【发布时间】：2020-08-11 18:38:27
【问题描述】：

provider "aws" {
  alias  = "sin"
  region = "ap-southeast-1"
}

provider "aws" {
  alias  = "mum"
  region = "ap-south-1"
}

resource "aws_sns_topic" "alarms_sin" {
  provider = aws.sin

  name = "${local.name_prefix}-alarms-${GET_CURRENT_REGION}"
}

resource "aws_sns_topic" "alarms_mum" {
  provider = aws.mum

  name = "${local.name_prefix}-alarms-${GET_CURRENT_REGION}"
}

通常，您可以使用data "aws_region" "current" {} 之类的数据块，但在这种情况下不起作用。

【解决方案1】：

我能够通过在数据块中添加提供程序来解决它 -

provider "aws" {
  alias  = "sin"
  region = "ap-southeast-1"
}

provider "aws" {
  alias  = "mum"
  region = "ap-south-1"
}

// Change
data "aws_region" "sin" {
  provider = "aws.sin"
}

data "aws_region" "mum" {
  provider = "aws.mum"
}

resource "aws_sns_topic" "alarms_sin" {
  provider = aws.sin

  name = "${local.name_prefix}-alarms-${data.aws_region.sin.name}"
}

resource "aws_sns_topic" "alarms_mum" {
  provider = aws.mum

  name = "${local.name_prefix}-alarms-${data.aws_region.mum.name}"
}
