Getting started

To use this repository it is recommended that you first create a fork.

Bootstrap

After creating a fork, there are a handful of quick bootrap scripts to get your repository up and running.

1. Setup specific environment variables unique to your GitHub Repository and Google Cloud Project. The script will request a couple inputs about the environment and output ./.env files with relevant variables.

   . ./scripts/bootstrap/01-setup-env.sh

   input(s):
   
   "Enter GitHub organization or owner [${_GITHUB_ORG}]: "
   "Enter GitHub repository name [${_GITHUB_REPO}]: "
   "Enter GCP project ID [${_GCP_PROJECT_ID}]: "
   "Enter default value region for this setup [${_GCP_LOCATION}]: "
   "Enter short (3-5 char) identifier for cloud resources (e.g. gcp) [$_GCP_CUSTOMER_ID]: "

   output:
   
   ./.env

2. Enable applicable Google Cloud APIs

   . ./scripts/bootstrap/02-enable-api.sh

3. Enable GitHub Actions by setting up variables in forked repository. GitHub Actions leverages Workload Identity Federation for "keyless" authentication. In this setup we use Worklaod Identity Federation through a Service Account (sa-terraform).

   . ./scripts/bootstrap/03-enable-gh-actions.sh

4. Setup IAM permissions for Google Service Account sa-terraform to deploy resources on our behalf.

   . ./scripts/bootstrap/04-enable-iam.sh

5. Finally we will setup Terraform backend on Google Cloud Storage for when we start deploying our resources with Terraform through GitHub Actions.

   . ./scripts/bootstrap/05-setup-tf.sh
