# gcp-subdomain-from-aws

Nullstone module to create a GCP-managed subdomain using an AWS domain.

## Overview

This module creates a DNS Zone on Google Cloud DNS.

By default, this module will create an SSL certificate using GCP Certificate Manager.
This can be disabled by setting the variable `disable_certificate = true`.
This certificate is created for Cloud CDNs and Load Balancing (most common use case).
A certificate and certificate map are created and emitted as outputs for use to attach to a GCP Load Balancer.

The `domain` connection refers to a Nullstone domain that is AWS-managed.
This module performs delegation -- it will add records to the root domain in AWS to direct the subdomain to newly-created GCP DNS Zone.
This allows a user to manage this subdomain fully in GCP without having access to the root domain in AWS.

## Subdomain Calculation

This module adds the current Nullstone environment into the FQDN for the resulting subdomain.

#### Example
Domain: `acme.com`
Env: `dev`
`dns_name`: `api`
FQDN: `api.dev.acme.com`

If `var.create_vanity = true`, then the environment chunk is omitted from the FQDN.
In the above example, the FQDN becomes: `api.acme.com`.
Typically, enabling this variable is done to create a production URL.
