[New Data Source]: aws_route53_zones Get list (!) of hosted zones

[DJAlPee]

Description

I have several hosted zones in my AWS account and some zones are sub-zones e.g. example.com, app1.example.com, app2.example.com, etc., which are managed by an "external" stack.

If I want to to place a new application to my account, I want to select the "best fitting" zone, depending on the domain for the new application:

• app1.example.com -> "" (empty) A record in app1.example.com
• new.example.com -> "new" A record in example.com
• very.deep.app2.example.com -> "very.deep" A record in example.com

I have already implented a some logic with terraform functions for selecting the zone, but for getting the list of hosted zones I'm using external provider, which just executes aws route53 list-hosted-zones --query HostedZones --output json (plus some hacky workaround by converting this output to base64, because this data source supports "key/value JSON", only)

It would be great, if I could use a native list data source for better stability and less external dependencies...
This new data source might be ideal for new contributers, because of existing similar list data sources and the "List" API is already being used by the existing aws_route53_zone(without trailing 's'):

terraform-provider-aws/internal/service/route53/zone_data_source.go

Line 116 in 42ad982

resp, err := conn.ListHostedZonesWithContext(ctx, req)

Requested Resource(s) and/or Data Source(s)

• aws_route53_zones

(Mind the trailing 's'!)

Potential Terraform Configuration

data "aws_route53_zones" "account_zones" {
  private_zone = false
}
