Serving Google Cloud Storage Content through Custom Domain over SSL

You may be using cloud storage for serving either dynamic and static content of your website or only static content such as images, videos, etc. In both cases, serving content from GCS over https is very important to secure your website.

If you have a website with dynamic content served from one platform like Google Appengine and static content served from cloud storage, implementing SSL on the platform which serves your dynamic content is not enough, you need to configure SSL for your domain or sub domain on cloud storage to make your website secure.

In this tutorial, you can learn how to implement SSL for your custom domain which points to cloud storage.

First make sure that you have a cloud storage bucket with content, then you need to Logon to cloud console and go to load balancing page by clicking network service and load balancing links in the left navigation.

Lastly, you need to update DNS record for the domain or sub domain that needs to be pointing to cloud storage bucket. To do that, you need to logon to your domain provider website which allows you to manage DNS for your domain and add A record to map your domain or sub domain to the IP address which was created while configuring load balancer on google cloud console. You can get the IP by clicking the load balancer on the load balancer screen of cloud console.
