Terraform GReseller Provider

This is a terraform provider to add feature needed to act as a Google Cloud (or a GSuite in the future) reseller. This module was heavily inspired by https://github.com/DeviaVir/terraform-provider-gsuite/

Usage

Please see first installation to use the plugin. If you already use GCP Terraform Provider, the most forward usage would be

provider "greseller" { }

resource "greseller_cloud_billing_account" "a_billing_account" {
  display_name = "MyAccount"
  master_billing_account = "billingAccounts/MASTER_BILLING_ACCOUNT_ID"
}

Authentication

There are two possible authentication mechanisms for using this provider. Using a service account, or a personal account. The latter requires user interaction, whereas a service account could be used in an automated workflow.

provider "greseller" {
}

Using a service account

Service accounts are great for automated workflows.

Add credentials when initializing the provider.

provider "gsuite" {
  credentials = "/full/path/service-account.json"
}

Credentials can also be provided via the following environment variables:

• GOOGLE_CREDENTIALS
• GOOGLE_CLOUD_KEYFILE_JSON
• GCLOUD_KEYFILE_JSON
• IMPERSONATED_USER_EMAIL

Using a personal account

Use Google Cloud SDK login mechanism and then run:

$ gcloud auth application-default login

Installation

1. Download the latest compiled binary from GitHub releases.

2. Unzip/untar the archive.

3. Move it into $HOME/.terraform.d/plugins:

   $ mkdir -p $HOME/.terraform.d/plugins
   $ mv terraform-provider-greseller $HOME/.terraform.d/plugins/terraform-provider-greseller

4. Create your Terraform configurations as normal, and run terraform init:

   $ terraform init

   This will find the plugin locally.

Available resources

Sub billing account

This allows you to create a sub billing account as a google cloud reseller.

resource "greseller_cloud_billing_account" "a_billing_account" {
  display_name = "MyAccount"
  master_billing_account = "billingAccounts/MASTER_BILLING_ACCOUNT_ID"
}

Properties:

• display_name: Sub billing account display name
• master_billing_account: master billing account id in the format billingAccounts/MASTER_BILLING_ACCOUNT_ID

Caveats

Google currently don't allow to close / open a sub account through API. A subaccount can not be deleted. WARNING: When you remove the subaccount from terraform, it will juste remove the reference from terraform but won't close the subaccount nor delete it.

Development

1. cd into $HOME/.terraform.d/plugins/terraform-provider-greseller

2. Run make dep to fetch the go vendor files

3. Make your changes

4. Run make dev and in your terraform directory, remove the current .terraform and re-run terraform init

5. Next time you run terraform plan it'll use your updated version
