Validate the certificates from 2 different accounts in AWS Terraform - amazon-web-services

Question

I have an individual(dev) account and the certificate is created based on the below module. The validation takes place in the root account (i.e., prod account) so when I go to the route 53 of the root account and add the domain entries (create record) and copy the CVALUE of the domain and paste it over there, then my individual account certificate gets validated and changed from "Pending Validation" to "Issued".
I want the below tf to add the entries (domain name and CVALUE) to the root account so that while terraform apply the certificate gets validated. Right now, I am manually adding the CVALUE entries to the root account for validation.
public_dns.tf
resource "aws_route53_zone" "public" {
name = var.domain
}
resource "aws_acm_certificate" "elb_cert" {
domain_name = var.domain
subject_alternative_names = ["*.${var.domain}"]
validation_method = "DNS"
}
resource "aws_route53_record" "cert_validation" {
for_each = {
for dvo in aws_acm_certificate.elb_cert.domain_validation_options : dvo.domain_name => {
name = dvo.resource_record_name
record = dvo.resource_record_value
type = dvo.resource_record_type
}
}
allow_overwrite = true
name = each.value.name
records = [each.value.record]
ttl = 60
type = each.value.type
zone_id = aws_route53_zone.public.zone_id
}
resource "aws_acm_certificate_validation" "elb_cert" {
count = var.certify_domain ? 1 : 0
certificate_arn = aws_acm_certificate.elb_cert.arn
validation_record_fqdns = [for record in aws_route53_record.cert_validation : record.fqdn]
}

Answer 1

To accomplish what you want, you will need to use multiple aws providers (alias).
One for the root account and one for the dev account, as you will be managing resources in two different accounts.
it will look something like this:
provider "aws" {
alias = "prod"
***
}
provider "aws" {
alias = "dev"
***
}
resource "aws_******"{
provider = aws.prod
***
***
}
resource "aws_******"{
provider = aws.dev
***
***
}
