Google Drive fsspec implementation

This is an implementation of the fsspec interface for Google Drive.

This software is in beta stage and should not be relied upon in production settings.

Installation

You can install it with pip from pypi or directly from source:

pip install gdrive_fsspec
pip install git+https://github.com/fsspec/gdrive-fsspec

Usage

As gdrivefs implements the fsspec interface, most documentation can be found at https://filesystem-spec.readthedocs.io/en/latest/usage.html.

Authentication

There are several methods to authenticate gdrivefs against Google Drive.

1. Service account credentials

In this method, you provide a dict containing the service account credentials obtained in the GCP console. The dict content is the same as the JSON file downloaded from the GCP console. More details can be found here: https://cloud.google.com/iam/docs/service-account-creds#key-types. This credential can be useful when integrating with other GCP services, and when you don't want the user to be prompted to authenticate.

from gdrive_fsspec import GoogleDriveFileSystem
fs = GoogleDriveFileSystem(creds=service_account_credentials,
                           token="service_account")

2. OAuth with user credentials

A browser will be opened to complete the OAuth authentication flow. Afterwards, the access token will be stored locally, and you can reuse it in subsequent sessions.

# use this the first time you run
token = 'browser'
# use this on subsequent attempts
# token = 'cache'
fs = GoogleDriveFileSystem(token=token)

On headless or remote machines (SSH sessions, containers, CI, and similar environments), you may not be able to bind a local callback server or open a browser on the same host. In that case, pass use_local_webserver: False in auth_kwargs to request a token via the console.

fs = GoogleDriveFileSystem(
    token=token,
    auth_kwargs={'use_local_webserver': False},
)

3. Anonymous (read-only) access

If you want to interact with files that are shared publicly ("anyone with the link"), then you do not need to authenticate to Google Drive.

token = 'anon'
fs = GoogleDriveFileSystem(token=token)

See GoogleDriveFileSystem docstring for more details.

Development

Running tests

The tests require defining the following environment variables:

• gdrive_fsspec_CREDENTIALS_PATH: location of a credentials.json or the json blob itself (starting with "{")
• gdrive_fsspec_CREDENTIALS_TYPE: token type ("service_account" default)
• gdrive_fsspec_DRIVE: shared drive to use.

As can be seen, the assumption is, that a service account will be operating on a shared drive. This requires the account to be have full shared access to the drive.

You could use your own personal gdrive too, either by creating a credentials JSON, or by using type "cache" following successful browser-based auth.

All tests take place in a directory "gdrive_fsspec_testdir".

pip install -e . pytest
pytest -v

Style

Please run pre-commit before submitting PRs. You can automate this by calling

$ pre-commit install

in the repo (once) before committing.
