Configure Google Cloud

Configure Google Cloud so Terraspace can connect to it. The recommended way is to:

  1. set up the ~/.gcp/credentials.json


To configure your GOOGLE_APPLICATION_CREDENTIALS you need to set up a service account. Follow the Google Getting Started with Authentication.

You’ll download a JSON credentials file that looks something like the following. This is just an example:


  "type": "service_account",
  "project_id": "project-123456",
  "private_key_id": "06410f6eb4d7701419afbaceb21d9a239EXAMPLE",
  "private_key": "-----BEGIN PRIVATE KEY-----\n...==\n-----END PRIVATE KEY-----\n",
  "client_email": "",
  "client_id": "109186985834EXAMPLE",
  "auth_uri": "",
  "token_uri": "",
  "auth_provider_x509_cert_url": "",
  "client_x509_cert_url": ""

In your ~/.bashrc or ~/.profile, use these lines to set environment variables:

export GOOGLE_APPLICATION_CREDENTIALS=~/.gcp/credentials.json
# The rest of the environment variables are used by the Google terraform provider. See:
export GOOGLE_PROJECT=$(cat ~/.gcp/credentials.json  | jq -r '.project_id')
export GOOGLE_REGION=us-central1
export GOOGLE_ZONE=us-central1-a

Note, it makes use of the jq command to grab the GOOGLE_PROJECT from the credentials.json file. You can either install jq or just add the actual value of your google project id.

Test Google API Access

To check that GOOGLE_APPLICATION_CREDENTIALS is valid and is working you can use the boltops-tools/google_check test script to check. Here are the summarized commands:

git clone
cd google_check
bundle exec ruby google_check.rb

You should see something like this:

$ bundle exec ruby google_check.rb
Listing gcs buckets as a test
Successfully connected to Google API with your GOOGLE_APPLICATION_CREDENTIALS

Note, if there are no buckets in the project, then no buckets will be listed, but you’ll still get a “Successfully connected” message

Set up gcloud cli

Though not necessary for Terraspace and Terraform to work, it is useful to also install the gcloud cli. Here are the instructions to install the Google SDK Install Docs. After you install it, you’ll need to login:

gcloud auth login

After you’ve authenticated, here are some useful commands to test that the GCP CLI is working:

gcloud config list
gcloud compute zones list --filter=region:us-central1

Next, we’ll create a new project.
