How to upload a file to Google Cloud Storage on Python 3?

Question

How can I upload a file to Google Cloud Storage from Python 3? Eventually Python 2, if it's infeasible from Python 3.

I've looked and looked, but haven't found a solution that actually works. I tried boto, but when I try to generate the necessary .boto file through gsutil config -e, it keeps saying that I need to configure authentication through gcloud auth login. However, I have done the latter a number of times, without it helping.

Answer 1

Use the standard gcloud library, which supports both Python 2 and Python 3.

Example of Uploading File to Cloud Storage

from gcloud import storage
from oauth2client.service_account import ServiceAccountCredentials
import os


credentials_dict = {
    'type': 'service_account',
    'client_id': os.environ['BACKUP_CLIENT_ID'],
    'client_email': os.environ['BACKUP_CLIENT_EMAIL'],
    'private_key_id': os.environ['BACKUP_PRIVATE_KEY_ID'],
    'private_key': os.environ['BACKUP_PRIVATE_KEY'],
}
credentials = ServiceAccountCredentials.from_json_keyfile_dict(
    credentials_dict
)
client = storage.Client(credentials=credentials, project='myproject')
bucket = client.get_bucket('mybucket')
blob = bucket.blob('myfile')
blob.upload_from_filename('myfile')
