Provides Google Cloud Storage (GCS) storage for Shrine.

gem "shrine-google_cloud_storage"

The GCS plugin uses the google-cloud-storage gem. Please refer to its documentation for setting up authentication.

require "shrine/storage/google_cloud_storage"

Shrine.storages = {
  cache: Shrine::Storage::GoogleCloudStorage.new(bucket: "cache"),
  store: Shrine::Storage::GoogleCloudStorage.new(bucket: "store"),
}

You can set a predefined ACL on created objects, as well as custom headers using the object_options parameter:

Shrine::Storage::GoogleCloudStorage.new(
  bucket: "store",
  default_acl: 'publicRead',
  object_options: {
    cache_control: 'public, max-age: 7200'
  },
)

Review the script test/create_test_environment.sh. It will:

• create a Google Cloud project
• associate it with your billing account
• create a service account
• add the roles/storage.admin iam policy
• download the json credentials
• create a test bucket
• add the needed variables to your .env file

To run, it assumes you have already run gcloud auth login. It also needs a .env file in the project root containing the project name and the billing account to use:

cp .env.sample .env
# Edit .env to fill in your project and billing accounts
./test/create_test_environment.sh

Create your own bucket and provide variables that allow for project and credential lookup. For example:

GCS_BUCKET=shrine-gcs-test-my-project
GOOGLE_CLOUD_PROJECT=my-project
GOOGLE_CLOUD_KEYFILE=/Users/user/.gcp/my-project/shrine-gcs-test.json

Warning: all content of the bucket is cleared between tests, create a new one only for this usage!

After setting up your bucket, run the tests:

$ bundle exec rake test

For additional debug, add the following to your .env file:

GCS_DEBUG=true
