Using a private google cloud storage with a custom domain

Question

I have an google cloud storage buckets and one rails app to access this buckets. My app works with files from 1M until 300M in uploads/downloads. On my rails app I use carriewave gem, so...all the throughput comes to my app, after to the bucket....until now, everything normal.

Recently I implementGCP direct upload but, the base url is storage.googleapis.com. This is terrible for my customers that have such a high level security in their local networks.

I need that storage.googleapis.com becomes storage.mycustomdomain.com. In this approach my customers will just allow *.mycustomdomain.com in their networks.

Someone could help me? Tnks

Cloud Storage public objects are served directly from GCP through storage.googleapis.com , as explained in the documentation . From John Hanley's comment, and according to this guide , Cloud Storage does not directly support custom domains:

Because Cloud Storage doesn't support custom domains with HTTPS on its own, this tutorial uses Cloud Storage with HTTP(S) Load Balancing to serve content from a custom domain over HTTPS.

The guide goes into creating a load balancer service which you can use to serve user content from your own domain, using the buckets as the service backend. Otherwise, it is also possible to create a CDN which is supported by Cloud Storage and uses a custom domain, as mentioned by the blog objectives:

• I want to serve images on my website (comparison for contact lenses) from a cloud bucket.
• I want to serve it from my domain, cdn.kontaktlinsen-preisvergleich.de
• I need HTTPS for that domain, because my website uses HTTPS everywhere and I don't want to mix that.

This related thread also mentions implementation of a CDN to use a custom domain to serve Cloud Storage objects.
