Set up your environment

This page walks you through the setup steps required to use the Cloud Spanner API with the Google Cloud CLI, client libraries, and Spanner drivers.

If you want to use Spanner with the Google Cloud console, see Quickstart using the console.

Set up a Google Cloud project

  1. Go to the Projects page in the Google Cloud console.

    Go to the Projects page

  2. Create a new Google Cloud project, or open an existing project by clicking on the project name.

  3. Open a terminal window, and set your project as the default project for the Google Cloud CLI, replacing MY_PROJECT_ID with your project ID (not your project name): 

    gcloud config set project MY_PROJECT_ID

  4. Make sure that billing is enabled for your Google Cloud project.

    5. You can also learn about Spanner pricing.

  5. Enable the Cloud Spanner API for the project.

    Enable the Cloud Spanner API

    Note: If you use a service account in a different project to access your Spanner instance, you need to enable the Spanner API in both projects.

Set up authentication

Select the tabs for how you plan to access the API:

Console

When you use the Google Cloud console to access Google Cloud services and APIs, you don't need to set up authentication.

gcloud

After installing the Google Cloud CLI, initialize it by running the following command: 

gcloud init

If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

Terraform

To use the Terraform samples on this page in a local development environment, install and initialize the gcloud CLI, and then set up Application Default Credentials with your user credentials.

  1. Install the Google Cloud CLI.

  2. If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

  3. To initialize the gcloud CLI, run the following command: 

    gcloud init

  4. If you're using a local shell, then create local authentication credentials for your user account: 

    gcloud auth application-default login

    You don't need to do this if you're using Cloud Shell.

    If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity.
