I'm trying to create a script to query google groups API from GCP instance. The instance has SA attached to it, this SA has SCOPE - 'https://www.googleapis.com/auth/admin.directory.group.readonly' allowed in GSuite, and the user is also setup in GSuite with a custom role attached to it(list groups).
For the SA I created a key file in GCP console. Then I get the credentials as documentation says:
from googleapiclient.discovery import build
from google.oauth2 import service_account
creds = service_account.Credentials.from_service_account_file(
SERVICE_ACCOUNT_FILE, scopes=SCOPES)
then add the user - to act as.
creds = creds.with_subject('[email protected]')
service = build('admin', 'directory_v1', credentials=creds)
results = service.groups().list(domain=tenant, maxResults=10,
orderBy='email',
query='email:{}*'.format(group_name)).execute()
Then I query API, everything works perfect and I get the groups.
So my question is: Is there a way to use the SA attached to the instance without generating the json key file. Like get compute_instance / default credentials / from instance metadata and then somehow authenticate them to the GSuite API?
Or is there a way to query groups without hitting Gsuite API, just call some from within GCP?
