Google Cloud Storage plugin Plugin

A plugin for uploading media files to Google Cloud Storage.

Google Cloud Storage plugin allows you to upload media files to a
Google Cloud Storage bucket.

Installation

Download the plugin and place it in your /wp-content/plugins/ directory.
Enable this plugin in the WordPress admin UI,
Configure your Google Cloud Storage bucket in the plugin setting
UI.
In Google Cloud Console, set the default acl of the bucket so that
allUsers can read.

Depending on your environment, you may need to configure a Google
Service Account to call the APIs.

To run this plugin on Google App Engine for PHP 7.2, it will work
without additional configuration.

To run this plugin on Google Compute Engine or App Engine Flexible,
you will need to do the following:

Visit Cloud Console, go to Compute -> instances and select
the instance where WordPress is running.
Stop the instance.
Once the instance has stopped, click Edit and you can now
modify the scopes under Cloud API access scopes. Change
the Storage scope from Read Only to Full.

If you want to run this plugin outside of Google Cloud Platform, you
need to configure your service account as follows:

Visit Cloud Console, go to IAM & Admin -> Service accounts
and create a service account with Storage Object Admin
permission and download the json key file.
Upload the json key file to the hosting server. Don’t put it
in a public serving area.
Add the following line to wp-config.php (replace the file path
with the real one).
putenv('GOOGLE_APPLICATION_CREDENTIALS=/secure-place/my-service-account.json');

A. See the section about configuring the service account in the
