# terraform-google-bootstrap



The purpose of this module is to help bootstrap a GCP organization, creating all the required GCP resources & permissions to start using the Cloud Foundation Toolkit (CFT). For users who want to use Cloud Build & Cloud Source Repos for foundations code, there is also a submodule to help bootstrap all the required resources to do this.



## Usage



Basic usage of this module is as follows:



```hcl

module "bootstrap" {

  source  = "terraform-google-modules/bootstrap/google"

  version = "~> 9.0"



  org_id               = ""

  billing_account      = ""

  group_org_admins     = "[email protected]"

  group_billing_admins = "[email protected]"

  default_region       = "australia-southeast1"

}

```



Functional examples are included in the

[examples](./examples/) directory.



## Features



The Organization Bootstrap module will take the following actions:



1. Create a new GCP seed project using `project_prefix`. Use `project_id` if you need to use custom project ID.

1. Enable APIs in the seed project using `activate_apis`

1. Create a new service account for terraform in seed project

1. Create GCS bucket for Terraform state and grant access to service account

1. Grant IAM permissions required for CFT modules & Organization setup

    1. Overwrite organization wide project creator and billing account creator roles

    1. Grant Organization permissions to service account using `sa_org_iam_permissions`

    1. Grant access to billing account for service account

    1. Grant Organization permissions to `group_org_admins` using `org_admins_org_iam_permissions`

    1. Grant billing permissions to `group_billing_admins`

    1. (optional) Permissions required for service account impersonation using `sa_enable_impersonation`



For the cloudbuild submodule, see the README [cloudbuild](./modules/cloudbuild).

## Requirements



### Software



-   [gcloud sdk](https://cloud.google.com/sdk/install) >= 206.0.0

-   [Terraform](https://www.terraform.io/downloads.html) >= 0.13.0

-   [terraform-provider-google] plugin 3.50.x



### Permissions



- `roles/resourcemanager.organizationAdmin` on GCP Organization

- `roles/orgpolicy.policyAdmin` on GCP Organization

- `roles/billing.admin` on supplied billing account

- Account running terraform should be a member of group provided in `group_org_admins` variable, otherwise they will loose `roles/resourcemanager.projectCreator` access. Additional members can be added by using the `org_project_creators` variable.



### Credentials



For users interested in using service account impersonation which this module helps enable with `sa_enable_impersonation`, please see this [blog post](https://cloud.google.com/blog/topics/developers-practitioners/using-google-cloud-service-account-impersonation-your-terraform-code) which explains how it works.



### APIs



A project with the following APIs enabled must be used to host the

resources of this module:



- Google Cloud Resource Manager API: `cloudresourcemanager.googleapis.com`

- Google Cloud Billing API: `cloudbilling.googleapis.com`

- Google Cloud IAM API: `iam.googleapis.com`

- Google Cloud Storage API `storage-api.googleapis.com`

- Google Cloud Service Usage API: `serviceusage.googleapis.com`



This API can be enabled in the default project created during establishing an organization.
