Per ottenere le autorizzazioni necessarie per utilizzare e interagire con i database Spanner, chiedi all'amministratore di concederti i seguenti ruoli IAM:
Crea un nuovo Google Cloud progetto o aprine uno esistente facendo clic sul nome del progetto.
...vedi le linee guida per l'assegnazione dei nomi
Apri una finestra del terminale e imposta il tuo progetto come progetto predefinito per
Google Cloud CLI, sostituendo
MY_PROJECT_ID con il tuo ID progetto (non il nome del progetto):
Per configurare gcloud CLI in modo che utilizzi la simulazione dell'identità dei service account per l'autenticazione alle
API di Google, anziché le tue credenziali utente, esegui questo comando:
Per utilizzare il codice Terraform in un ambiente di sviluppo locale, installa e inizializza
gcloud CLI, quindi configura le credenziali predefinite dell'applicazione con le tue credenziali
utente.
Per utilizzare le librerie client in un ambiente di sviluppo locale, installa e inizializza
gcloud CLI, quindi configura le credenziali predefinite dell'applicazione e con le tue credenziali
utente.
Per configurare il file ADC locale in modo che utilizzi la simulazione dell'identità dei service account per l'autenticazione alle API di Google, anziché le credenziali utente, esegui il seguente comando:
Puoi utilizzare l'imitazione dell'account di servizio per generare un token di accesso per le richieste API REST.
Per saperne di più, vedi
Service account con rappresentazione.
Esegui Google Cloud CLI
Ora che hai configurato l'ambiente di sviluppo e l'autenticazione, esegui lo strumento a riga di comando
gcloud per interagire con
Spanner:
gcloudspannerinstance-configslist
Dovresti visualizzare un elenco delle configurazioni di istanza Spanner a cui
il tuo progetto può accedere, incluse le configurazioni regionali, a due regioni e multiregionali. Per saperne di più, consulta la panoramica
delle istanze.
Hai completato la configurazione.

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.
