設定應用程式預設憑證

如要在 Vertex AI 上使用 Gemini，您必須使用 Google Cloud API 金鑰或應用程式預設憑證進行驗證。建議您在測試時使用 API 金鑰，並在正式環境中使用應用程式的預設憑證。本頁面說明如何設定應用程式預設憑證。

事前準備

選取專案、啟用帳單功能、啟用 Vertex AI API、安裝 gcloud CLI

  1. Sign in to your Google Account.

    If you don't already have one, sign up for a new account.

  2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

    Go to project selector

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

  4. Enable the Vertex AI API.

    Enable the API

  5. Install the Google Cloud CLI.

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

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

    gcloud init

  8. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

    Go to project selector

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

  10. Enable the Vertex AI API.

    Enable the API

  11. Install the Google Cloud CLI.

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

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

    gcloud init

建立本機驗證憑證

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.
