Terraform

Prerequisite

GCP project is already created and linked to a billing account.

Set up backend (optional)

Note

You can skip this step if you use an existing bucket for Terraform state.

1. Set up variables.

   PROJECT="cloud-run-template-naka"
   REGION="asia-northeast1"
   BUCKET="cloud-run-template-naka-terraform"
   

2. Login

   gcloud auth login
   

3. Create a GCS bucket for Terraform state.

   gsutil mb -p "$PROJECT" -l "$REGION" gs://"$BUCKET"
   

Initial Setup

1. Create your new GitHub repository from this template.

   gh repo create <your new repo name> --template=nakabonne/cloud-run-app-template
   

2. Write your own terraform.tfvars and terraform.tfbackend file.

   cp terraform.tfvars.example terraform.tfvars
   

   Example of terraform.tfvars:

   project      = "cloud-run-template-naka"
   region       = "asia-northeast1"
   service_name = "cloud-run-template"
   

   cp terraform.tfbackend.example terraform.tfbackend
   

   Example of backend.tfbackend:

   bucket  = "cloud-run-template-naka-terraform"
   prefix  = "terraform/state"
   

3. Log in to GCP.

   gcloud auth application-default login
   

4. Init

   terraform init -backend-config=terraform.tfbackend
   

5. Apply

   terraform apply
   

   [!WARNING] It might fail for the first time, because it takes some time to enable the Cloud Run service API. Please try again.

6. Set GitHub repository secrets

   gh secret set PROVIDER_NAME --body=$(terraform output github_actions_provider_name | tr -d '"')
   gh secret set SA_EMAIL --body=$(terraform output github_actions_sa_email | tr -d '"')
   

7. Create a PR!

   GitHub Actions will be run with the service account created by Terraform.
