Using Google Storage Bucket As a Site Origin – StackPath Help Center

Setting up the StackPath CDN to use a Google Cloud Storage (GCS) bucket as an origin is a simple process that may require setting up storage.objects.list permissions for the StackPath CDN. This article will walk you through the setup process.

This article assumes you have already created a StackPath account, and have already performed the basic setup for a Google Cloud Storage Bucket.

Setting Up Bucket Access

For this example, the bucket was set up with Public Read access that allows everyone to view the bucket contents. This can be done by configuring bucket specific permissions and adding a rule, specifying all users the ability to read objects.

Select the bucket settings drop-down and select edit bucket permissions
Typ allUsers into the "Add members" field, and choose Storage Object Viewer from the Select Role drop-down
Select Add and then the bucket will have global read-only permissions

Setting Up The CDN

In this tutorial, a bucket named "stackpathtesting" was used for integration. Replace any instance of "stackpathtesting" or <bucketname> with the actual name of the bucket you would like to integrate.

Log in to the StackPath Control Panel
Create a new Site
Create the Domain Name you would like to use, this can be any fully qualified domain name. For this example, the bucket address was used.
Specify your bucket URL. Select "Origin Authentication" value, or leave at the default "None" if no authentication is required.

4.2 Go into the Settings tab for the newly created Site and confirm that the Host Header is <bucketname>.storage.googleapis.com. You can check the full host header by clicking on the dropdown menu, or add this as a custom option, if necessary.
Test the Site's Edge Address by navigating via the browser. This should produce an XML file that indexes the content of your GCS Bucket, showing that the CDN has access. The Edge Address can now be used to view any objects inside the bucket by going to http://cdnurl/path/to/object (Replacing cdnurl with the actual Edge Address that was provided upon creating the Site.)
