How to pass subdomains and domains

[Saba-Shavidze]

I'm trying to pass domains to Route53 like this:

  domain_config = {
    viewer_certificate = {
      acm_certificate_arn = local.acm_certificate_arn
    }
    sub_domain = "dev"
    hosted_zones = [
      {
        name = "dev.abc.ge"
      },
      {
        name = "www.dev.abc.ge"
      }
    ]
  }

but getting this error

Error: no matching Route53Zone found │ │ with module.deploy.module.public_resources[0].data.aws_route53_zone.hosted_zone["www.dev.abc.ge-false"], │ on terraform-aws-open-next/modules/tf-aws-open-next-public-resources/data.tf line 5, in data "aws_route53_zone" "hosted_zone": │ 5: data "aws_route53_zone" "hosted_zone" {

What is this -false? What am I doing wrong?

hi @Saba-Shavidze,

What is this -false? This flag indicates whether the hosted zone is private (true) or public (false). This documentation https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/hosted-zones-private.html provides more context on private hosted zones

It looks like the issue is with the "www.dev.abc.ge" hosted zone.

Are you trying to have the domain dev.abc.ge associated with the distribution? If so, assuming you have a hosted zone called abc.ge, you would need to set the subdomain argument to be "dev" If your hosted zone is called dev.abc.ge, then you can omit the subdomain

[Saba-Shavidze]

No, I just need to have two 2 records for this domain dev.abc.ge and www.dev.abc.ge

[RJPearson94]

Hi @Saba-Shavidze, I just noticed a bit of a flaw in the module. So you can add dev.abc.ge however I need to modify the module to support www.dev.abc.ge

If your hosted zone is set to dev.abc.ge you will need the following config

domain_config = {
    viewer_certificate = {
      acm_certificate_arn = local.acm_certificate_arn
    }
    hosted_zones = [
      {
        name = "dev.abc.ge"
      }
    ]
  }

If your hosted zone is set to abc.ge you will need the following config

domain_config = {
    viewer_certificate = {
      acm_certificate_arn = local.acm_certificate_arn
    }
    sub_domain = "dev"
    hosted_zones = [
      {
        name = "abc.ge"
      }
    ]
  }

[RJPearson94]

to support www.dev.abc.ge I am going to add another input argument (likely called include_www) to domain_config to allow this to be conditionally enabled. to prevent a change in behaviour the default of this will be false

So the terraform config would be

domain_config = {
    viewer_certificate = {
      acm_certificate_arn = local.acm_certificate_arn
    }
    include_www = true
    sub_domain = "dev"
    hosted_zones = [
      {
        name = "abc.ge"
      }
    ]
  }

Does that work for you?

[RJPearson94]

I just need to write up some documentation. Hopefully, will have a patch out by the 7th March.

[Saba-Shavidze]

Yes, as soon as possible if u have a time, or give me some sugesstion how to do that. Also, there is an error when trying to update the domain names:

creating Route 53 Record: InvalidChangeBatch: [Tried to create resource record set [name='dev.abc.ge.', type='A'] but it already exists]
│       status code: 400, request id: 346ebe8f-c80b-4bf8-a09c-12

Maybe we need to set allow_overwrite = true for route53

[RJPearson94]

Hey @Saba-Shavidze, I have pushed out v2.3.0 of the module, this should allow you to set the www subdomain and also configure the module to override the Route53 entries

[RJPearson94]

You will need to update your terraform configuration to include the following

domain_config = {
    viewer_certificate = {
      acm_certificate_arn = local.acm_certificate_arn
    }
    include_www = true
    route53_record_allow_overwrite = true
    sub_domain = "dev"
    hosted_zones = [
      {
        name = "abc.ge"
      }
    ]
  }

The full documentation for the possible configuration options can be found at https://github.com/RJPearson94/terraform-aws-open-next/blob/main/docs/domain-config.md

[Saba-Shavidze]

Thanks, I will update it for tomorrow and update about my updates as well ❤️😀

[Saba-Shavidze]

One quick question why you changed the route53_entries to temp_aliases in /modules/tf-aws-open-next-public-resources/main.tf

[RJPearson94]

So I needed a new local variable to hold a value internally then conditionally apply another modification. The aliases local is set using the temp variable

[RJPearson94]

I misread your message slightly. 2 new locals were introduced for route53_entries and aliases. to hold temporary values to apply subsequent changes conditionally.

Aliases before

aliases = var.domain_config != null ? formatlist(join(".", compact([var.domain_config.sub_domain, "%s"])), distinct([for hosted_zone in var.domain_config.hosted_zones : hosted_zone.name])) : []

Aliases after

temp_aliases = var.domain_config != null ? concat(formatlist(join(".", compact([var.domain_config.sub_domain, "%s"])), distinct([for hosted_zone in var.domain_config.hosted_zones : hosted_zone.name]))) : []

aliases = try(var.domain_config.include_www, false) == true ? flatten([for alias in local.temp_aliases : [alias, "www.${alias}"]]...) : local.temp_aliases

Route 53 entries before

route53_entries = try(var.domain_config.create_route53_entries, false) == true ? { for hosted_zone in var.domain_config.hosted_zones : join("-", compact([hosted_zone.name, hosted_zone.id, hosted_zone.private_zone])) => { name = join(".", compact([var.domain_config.sub_domain, hosted_zone.name])) zone_id = coalesce(hosted_zone.id, data.aws_route53_zone.hosted_zone[join("-", compact([hosted_zone.name, hosted_zone.private_zone]))].zone_id) } } : {}

Route 53 entries after

temp_route53_entries = try(var.domain_config.create_route53_entries, false) == true ? { for hosted_zone in var.domain_config.hosted_zones : join("-", compact([hosted_zone.name, hosted_zone.id, hosted_zone.private_zone])) => { name = join(".", compact([var.domain_config.sub_domain, hosted_zone.name])) zone_id = coalesce(hosted_zone.id, data.aws_route53_zone.hosted_zone[join("-", compact([hosted_zone.name, hosted_zone.private_zone]))].zone_id) allow_overwrite = var.domain_config.route53_record_allow_overwrite } } : {}

route53_entries = try(var.domain_config.include_www, false) == true ? merge([for name, route53_details in local.temp_route53_entries : { "${name}" = route53details, "www${name}" = { name = "www.${route53_details.name}", zone_id = route53_details.zone_id, allow_overwrite = route53_details.allow_overwrite } }]...) : local.temp_route53_entries

Have you managed to resolve your issue?

[Saba-Shavidze]

@RJPearson94 I'll update you for Monday.

[Saba-Shavidze]

Hi again, It didn't add alternate domain name with www : www.dev.abc.ge

[RJPearson94]

Are you able to share your terraform/ terragrunt config? Can I just check you are using v2.3.0 of the module too?

[Saba-Shavidze]

  domain_config = {
    viewer_certificate = {
      acm_certificate_arn = local.acm_certificate_arn
    }
    include_www = true
    route53_record_allow_overwrite = true
    hosted_zones = flatten([
      for name in keys(local.route53_zone_zone_id) : { name = name }
    ])
  }

Yes I'm using latest version v2.3.0.

[RJPearson94]

Hi @Saba-Shavidze,

I have been unable to replicate this using Terraform or OpenTofu. I have been able to deploy a website with www subdomain using the following terraform code

data "aws_caller_identity" "current" {}

locals {
    route53_zone_zone_id = { "abc.co.uk": "test" }
}

module "zone" {
  source = "RJPearson94/open-next/aws//modules/tf-aws-open-next-zone"
  version = "2.3.0"

  prefix = "open-next-sz-${data.aws_caller_identity.current.account_id}"
  folder_path = "./.open-next"
  s3_exclusion_regex = ".*\\.terragrunt*"

  continuous_deployment = {
    use = true
    deployment = "NONE"
    traffic_config = {
      header = {
        name = "aws-cf-cd-staging"
        value = "true"
      }
    }
  }

  website_bucket = {
    force_destroy = true
  }

  domain_config = {
    route53_record_allow_overwrite = true
    include_www = true
    hosted_zones = flatten([
      for name in keys(local.route53_zone_zone_id) : { name = name }
    ])

    viewer_certificate = {
        acm_certificate_arn = "arn:aws:acm:us-east-1:11111111111:certificate/abc1234"
    }
  }

  providers = {
    aws.server_function = aws.server_function
    aws.iam = aws.iam
    aws.dns = aws.dns
    aws.global = aws.global
  }
}

In CloudFront, this created the following

Note: I have changed the html to mask my account/ CloudFront details

I hope this helps, but if you require any further assistance, I would need access to your Terraform script to see if I can replicate the issue

Kind Regards Rob

[shavidze]

hmm, I will try again.

It actually created and add the www domain, but throw this error while deploying application

[Saba-Shavidze]

I resolved it, you can close the issue. Thanks a lot for your help.

[RJPearson94]

No problem, glad I could help
