Terraform Providers

Providers are plugins that allow Terraform to integrate into different sources and types of cloud infrastructure. AWS is example of a provider.

Multiple Providers

There are multiple regions in AWS. To specify resources in different regions, define multiple terraform providers.

For example, there is a requirement that AWS CloudFront certificates must be issued in the us-east-1.

provider "aws" {
  region = "ap-southeast-1"
  profile = "myapp"
}

provider "aws" {
  region = "us-east-1"
  alias = "us-east-1"
  profile = "myapp"
}

Then the certificate resource can reference the relevant provider attribute. The first entry above is aws while the second entry is referred to as aws.us-east-1

resource "aws_acm_certificate" "www_example_com" {
  domain_name       = "www.example.com"
  validation_method = "DNS"
  provider = aws.us-east-1
}
