License
GNU General Public License, version 3 or later.

Installing
pip install gcsannex

Configuring Google Cloud Storage

Log into the Google Developers Console.
Create a project if you don’t already have one. Remember its
project ID.
In the project’s settings, go to APIs & auth > Credentials.
Click “Create new Client ID”, select “Service account”, then click
“Create Client ID”.
A credentials file will be downloaded to your computer. You will need
this file when configuring gcsannex.

Adding a remote
git annex initremote <remotename> type=external externaltype=gcs encryption={none|shared|pubkey|hybrid} project=<gcs-project-id>
Set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the
path to your credentials file. This is only necessary when running
initremote; afterward, git-annex will remember your credentials.

Mandatory settings

encryption
See the git-annex encryption documentation.

project
Your project ID from the Google developer console.

Optional settings

bucket
The bucket name, which must be globally unique within GCS. The default
name is based on the remote name and UUID.

chunk
Enable chunking.

embedcreds
Set to yes to commit the login credentials to the Git repository
so other clones can read them. When using GPG encryption, the default is
yes and the credentials are stored encrypted. Otherwise, the default
is no; if set to yes, anyone with access to the repo can also
access the GCS bucket.

fileprefix
A string, such as mydata/, to be prepended to the name of each object.
This allows a bucket to be shared by multiple remotes.

location
The physical location for the data. Can be any of the location strings
supported by GCS, such as ASIA, EU, or US. Defaults to US.

public
If yes, newly-uploaded objects are made publicly readable. Defaults
to no.

readonly
If set to true when enabling an existing public remote, files
can be retrieved without GCS credentials and without gcsannex installed.
Requires development version of git-annex.

storageclass
A storage class supported by GCS, such as STANDARD,
DURABLE_REDUCED_AVAILABILITY, or NEARLINE. Defaults to
STANDARD.
