Pour obtenir les autorisations nécessaires pour utiliser les bases de données Spanner et interagir avec elles, demandez à votre administrateur de vous accorder les rôles IAM suivants :
Créez un projet Google Cloud ou ouvrez un projet existant en cliquant sur son nom.
...Afficher les consignes d'attribution de noms
Ouvrez une fenêtre de terminal et définissez votre projet comme projet par défaut pour la Google Cloud CLI. Pour ce faire, remplacez MY_PROJECT_ID par l'ID de votre projet (et non pas son nom) dans la commande suivante :
Remarque : Si vous utilisez un compte de service dans un autre projet pour accéder à votre instance Spanner, vous devez activer l'API Spanner dans les deux projets.
Configurer l'authentification
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
Installez la Google Cloud CLI.
Une fois que la Google Cloud CLI est installée, initialisez-la en exécutant la commande suivante :
Pour configurer la gcloud CLI afin qu'elle utilise l'emprunt d'identité d'un compte de service pour s'authentifier auprès des Google APIs plutôt que d'utiliser vos identifiants utilisateur, exécutez la commande suivante :
Pour utiliser le code Terraform dans un environnement de développement local, installez et initialisez la gcloud CLI, puis configurez le service Identifiants par défaut de l'application avec vos identifiants utilisateur.
Pour utiliser des bibliothèques clientes dans un environnement de développement local, installez et initialisez la gcloud CLI, puis configurez le service Identifiants par défaut de l'application avec vos identifiants utilisateur.
Pour configurer votre fichier ADC local afin d'utiliser l'emprunt d'identité d'un compte de service pour vous authentifier auprès des Google APIs plutôt que vos identifiants utilisateur, exécutez la commande suivante :
Pour en savoir plus, consultez la section S'authentifier pour utiliser REST dans la documentation sur l'authentification Google Cloud .
Vous pouvez utiliser l'emprunt d'identité d'un compte de service pour générer un jeton d'accès pour les requêtes API REST.
Pour en savoir plus, consultez la section Compte de service dont l'identité est empruntée.
Exécuter la Google Cloud CLI
Maintenant que vous avez configuré l'environnement de développement et l'authentification, exécutez l'outil de ligne de commande gcloud pour interagir avec Spanner :
gcloudspannerinstance-configslist
La liste des configurations d'instance Spanner auxquelles votre projet a accès doit s'afficher. Elle inclut les configurations régionales, birégionales et multirégionales. Pour en savoir plus, consultez la présentation des instances.
Vous avez terminé la configuration.
Étapes suivantes
Apprenez à utiliser les bibliothèques clientes et les pilotes Cloud pour créer une instance, une base de données, des tables et des index Spanner. Ensuite, stockez, interrogez et lisez des données dans Spanner.

Create a new Google Cloud project, or open an existing project by clicking on the project name.\n| **Important:** The name you use must be between 4 and 30 characters. When you type the name, the form will suggest a project ID, which you can edit. The project ID you use must be between 6 and 30 characters, with a lowercase letter as the first character. You can use a dash, lowercase letter, or digit for the remaining characters, but the last character cannot be a dash. You should be aware that some resource identifiers (such as project IDs) might be retained beyond the life of your project. For this reason, avoid storing sensitive information in resource identifiers.\n...see naming guidelines\n3.\n Open a terminal window, and set your project as the default project for\n the Google Cloud CLI, replacing\n `MY_PROJECT_ID` with your project ID (not your project name):\n\n gcloud config set project \u003cvar translate=\"no\"\u003eMY_PROJECT_ID\u003c/var\u003e\n\n4.
