在Terraform中，是否有一种为模块使用不同提供程序的方法？

Question

我使用https://github.com/cloudposse/terraform-aws-acm-request-certificate生成证书，使用terraform和aws。

有什么方法可以为模块使用不同的提供程序吗？

我的意思是，在第一个模块中，我想在我们-东-1区域做，另一个我想在我们-东-2做。

但是，由于我有一个提供程序，这可以在单一文件或单一目录中的terraform完成吗？

provider "aws" {
  version = "~> 2.12.0"
  profile = "..."
  region  = "us-east-1"
}

module "example_com" {
  # Should be in us-east-1
  source                            = "git::https://github.com/cloudposse/terraform-aws-acm-request-certificate.git?ref=master"
  domain_name                       = "example.com"
  process_domain_validation_options = false
  ttl                               = "300"
  subject_alternative_names         = ["*.example.com"]
}

module "cdn_example_com" {

  # Should be in us-east-2
  source                            = "git::https://github.com/cloudposse/terraform-aws-acm-request-certificate.git?ref=master"
  domain_name                       = "cdn.example.com"
  process_domain_validation_options = false
  ttl                               = "300"
}

类似于：

provider "aws" "aws-east-1" {
  version = "~> 2.12.0"
  profile = "..."
  region  = "us-east-1"
}

provider "aws" "aws-east-2" {
  version = "~> 2.12.0"
  profile = "..."
  region  = "us-east-2"
}

module "example_com" {
  provider = "aws-east-1"

  source                            = "git::https://github.com/cloudposse/terraform-aws-acm-request-certificate.git?ref=master"
  domain_name                       = "example.com"
  process_domain_validation_options = false
  ttl                               = "300"
  subject_alternative_names         = ["*.example.com"]
}

module "cdn_example_com" {

  provider = "aws-east-2"

  # Should be in us-east-2
  source                            = "git::https://github.com/cloudposse/terraform-aws-acm-request-certificate.git?ref=master"
  domain_name                       = "cdn.example.com"
  process_domain_validation_options = false
  ttl                               = "300"
}

基于地形记录，您可以创建不同的提供程序，并将它们“传递”给模块。

就您的情况而言，这可能是以下情况：

provider "aws" {
  version = "~> 2.12.0"
  profile = "..."
  region  = "us-east-1"
}


# create second provider with alias of "us-east-2" 
provider "aws" {
  version = "~> 2.12.0"
  profile = "..."
  region  = "us-east-2"
  alias   = "us-east-2" 
}

#
# Then for your modules
#

# use default provider
module "example_com" {

  source                            = "git::https://github.com/cloudposse/terraform-aws-acm-request-certificate.git?ref=master"
  domain_name                       = "example.com"
  process_domain_validation_options = false
  ttl                               = "300"
  subject_alternative_names         = ["*.example.com"]
}


# use non-default provider
module "cdn_example_com" {

   providers = {
    aws = aws.us-east-2
  }

  # Should be in us-east-2
  source                            = "git::https://github.com/cloudposse/terraform-aws-acm-request-certificate.git?ref=master"
  domain_name                       = "cdn.example.com"
  process_domain_validation_options = false
  ttl                               = "300"
}
