Terraform GCP plans

Prerequisites

A GCP organization
A top-level GCP folder within that organization where the plans will create resources within.

Modify all variables, depending on the TF plan, within variables.tf or overriding them through environment variables, according to your company, such as:
- var.shared_suffix, which should not be a long string.
- var.group_*
- var.region
- var.billing_id
- var.org_id
- var.directory_customer_id
Execute the following plans first:
- gcp-terraform
- gcp-organization
Then feel free to execute the other plans as you need.
Once the gcp-terraform plan has been executed, you can use the resulting terraform GCP serviceaccount in your automated CI/CD.
You can then also uncomment the GCS backend state configuration in every plan.
