Carrierwave Google Storage

Use the official google-cloud gem by Google for Google Cloud Storage, instead of Fog.

• No need to activate Interoperable Access on your project.
• Rely on Google's preferred authentication mechanism. ie: Service Accounts.

Add this line to your application's Gemfile:

gem 'privy-carrierwave-google-storage'

• Rails 4 and 5.

In config/initializers/carrierwave.rb add the following initialization code:

CarrierWave.configure do |config|
  config.storage                             = :gcloud
  config.gcloud_bucket                       = 'your-bucket-name'
  config.gcloud_bucket_is_public             = true
  config.gcloud_authenticated_url_expiration = 600
  config.gcloud_content_disposition          = 'attachment' // or you can skip this

  config.gcloud_attributes = {
    expires: 600
  }

  config.gcloud_credentials = {
    gcloud_project: 'gcp-project-name',
    gcloud_keyfile: 'path-to-gcp-keyfile.json'
  }
end

Then, in your Uploader classes:

class FileUploader < CarrierWave::Uploader::Base
   storage :gcloud
end

To generate a new keyfile, perform the following steps:

• Go to Cloud Console > API Manager > Credentials
• Click Create Credentials > Service Account Key
• Service Account > New Service Account
• Give any name for "Service Account Name"
• Set Key type to JSON
• Click "Create"

Here's a quick GIF for those who are visual like myself:

You should have access to a Google Cloud Platform account, as you'll need the keyfile and a project ID in order to contribute to the development of this gem. You'll need the the following files:

• .gcp-keyfile.json (sample file provided: .gcp-keyfile.sample.json)
• .env (sample file provided: .env.sample)
