To use Google Cloud CDN on top of your current Google Storage bucket in Django, you only need to set a custom domain (or IP) of your CDN.

For example, in settings.py:

GS_CUSTOM_ENDPOINT = 'https://cdn.yourdomain.com'

On your domain registrar, the custom endpoint should direct to the IP of the load balancer you set in Google Cloud.
