gsutil: specify project on copy

Question

I'm attempting to come up with commands to facilitate deployment to different environments (production, staging) in my GCP project using gsutil.

The following deploys to production without issue:

gsutil cp -r ./build/* gs://<production-project-name>/

I'd like to deploy to a bucket in another project. The gsutil help page alludes to a -p option for ls and mb used to change the project context of the gsutil command.

I'd like to use a command like this to deploy my app to a staging environment:

gsutil cp -r ./build/* gs://<existing-bucket-in-staging-project>/ -p <staging-project-name>

Alas, the -p option is not available for the cp command. I confirmed on the gsutil cp doc page.

What is the best way to deploy a build artifact to a Google Cloud storage bucket to a bucket in a project other than the one currently specified in the terminal environment?

Answer 1

The bucket namespace is global, so as long as the credentials you're using have permission to the other project, you shouldn't need a project parameter with the cp command. In other words, this command should work fine:

gsutil cp -r ./build/* gs://<bucket-in-staging-project>
