Impersonated Credentials allows credentials issued to a user or service account to impersonate another. The target service account must grant the originating credential principal the `Service Account Token Creator`_ IAM role: For more information about Token Creator IAM role and IAMCredentials API, see `Creating Short-Lived Service Account Credentials`_. .. _Service Account Token Creator: https://cloud.google.com/iam/docs/service-accounts#the_service_account_token_creator_role .. _Creating Short-Lived Service Account Credentials: https://cloud.google.com/iam/docs/creating-short-lived-service-account-credentials Usage: First grant source_credentials the `Service Account Token Creator` role on the target account to impersonate. In this example, the service account represented by svc_account.json has the token creator role on `impersonated-account@_project_.iam.gserviceaccount.com`. Enable the IAMCredentials API on the source project: `gcloud services enable iamcredentials.googleapis.com`. Initialize a source credential which does not have access to list bucket:: from google.oauth2 import service_account target_scopes = [ 'https://www.googleapis.com/auth/devstorage.read_only'] source_credentials = ( service_account.Credentials.from_service_account_file( '/path/to/svc_account.json', scopes=target_scopes)) Now use the source credentials to acquire credentials to impersonate another service account:: from google.auth import impersonated_credentials target_credentials = impersonated_credentials.Credentials( source_credentials=source_credentials, target_principal='impersonated-account@_project_.iam.gserviceaccount.com', target_scopes = target_scopes, lifetime=500) Resource access is granted:: client = storage.Client(credentials=target_credentials) buckets = client.list_buckets(project='your_project') for bucket in buckets: print(bucket.name) Ncstt|t||_t|jtjr,|jt j |_t |jdr,|jj r,|j d||_||_||_|p8t|_d|_t|_||_||_d|_dS)aL Args: source_credentials (google.auth.Credentials): The source credential used as to acquire the impersonated credentials. target_principal (str): The service account to impersonate. target_scopes (Sequence[str]): Scopes to request during the authorization grant. delegates (Sequence[str]): The chained list of delegates required to grant the final access_token. If set, the sequence of identities must have "Service Account Token Creator" capability granted to the prceeding identity. For example, if set to [serviceAccountB, serviceAccountC], the source_credential must have the Token Creator role on serviceAccountB. serviceAccountB must have the Token Creator on serviceAccountC. Finally, C must have Token Creator on target_principal. If left unset, source_credential must have that role on target_principal. lifetime (int): Number of seconds the delegated credential should be valid for (upto 3600). quota_project_id (Optional[str]): The project ID used for quota and billing. This project may be different from the project used to create the credentials. iam_endpoint_override (Optiona[str]): The full IAM endpoint override with the target_principal embedded.
