Share Google Cloud Storage Bucket across Projects

Question

I want a storage bucket to be owned by multiple projects, without the use of a service account. How can I accomplish this?

Answer 1

Google Cloud Storage buckets can only belong to a single project, and that project will foot the bill for that bucket. Permissions can absolutely span multiple accounts, though. Any permission for a user or a group that can be applied to a bucket in one project can also be applied to a bucket in another project.

What exactly are you hoping to do?
