Terraform CloudFormation Multi Region Stacksets

[rads18]

Hello team,

We have been using AWS Stacksets to deploy directly from AWS UI(Cloudformation) and trying to use Terraform to deploy the same Stacksets templates.

Based on documentation it appears we should be able to supply multiple regions but i do not see a key to supply multiple regions for parallel execution. However, per document (link below) for Resource: aws_cloudformation_stack_set_instance it has a operational_preference parameter that allows PARALLEL execution.

region_concurrency_type

• (Optional) The concurrency type of deploying StackSets operations in Regions, could be in parallel or one Region at a time.

thanks Rads

Note: The below configuration works But only for one region (us-east-1). There is not provision to provide multiple regions, yet in the instance configuration and documentation we can do PARALLEL, what is the meaning and significance for that? Hence, the confusion!

CreateCloudstackSet.tf

resource "aws_cloudformation_stack_set" "amitest" {
  name = "ami-test-stackset"

  parameters = {
    ImageName = "xxxxxx"
  }

  template_body = file("../cftemplates/TestAmiLambda.yaml")
}

My instance.tf file is:

resource "aws_cloudformation_stack_set_instance" "amitest" {
  account_id = "xxxxxxxx"
  region     = "us-east-1"
  timeouts {
    create = "60m"
  }
  operation_preferences {
    region_concurrency_type = "PARALLEL"
  }
  stack_set_name = aws_cloudformation_stack_set.amitest.name
}

main.tf

provider "random" {}

## Provider us-east-1
provider "aws" {
  region = "us-east-1"
}

Hi @rads18 👋

Sorry you ran into trouble here.

I'm wondering if perhaps this issue should have been opened on the AWS Terraform Provider repository as the aws_cloudformation_stack_set_instance is part of the AWS provider.

Thanks @bendbennett for getting back to me .
