Create GCP Recources

Create resource by Terraform

Run on infra dir

cd infra && make init

1. Comment out secret resources(infra/secrets.tf)

2. Create resource exclude secret

make plan
make apply -auto-approve

3. Encrypt your production secrets: rails_master_key, pscale_db_user, pscale_db_password

e.g)

echo -n $RAILS_MASTER_KEY | gcloud kms encrypt --location asia-northeast1 --keyring ring1 --key crypto1 --plaintext-file - --ciphertext-file - | base64

4. Set google_kms_secret, and uncomment

e.g)

data "google_kms_secret" "rails_master_key" {
  crypto_key = google_kms_crypto_key.crypto_key.id
  # Must Replace!: echo -n $RAILS_MASTER_KEY | gcloud kms encrypt --location asia-northeast1 --keyring key-ring --key crypto-key --plaintext-file - --ciphertext-file - | base64
  ciphertext = ### Here! ###
}

5. Create secret

make
make apply -auto-approve
