Listing all public links for all objects in a bucket using gsutil

Question

Is there a way to list all public links for all the objects stored into a Google Cloud Storage bucket (or a directory in a bucket) using Cloud SDK's gsutil or gcloud?

Something like:

$ gsutil ls --public-link gs://my-bucket/a-directory

Answer 1

Public links for publicly visible objects are predictable. They just match this pattern: https://storage.googleapis.com/BUCKET_NAME/OBJECT_NAME.

gsutil doesn't have a command to print URLs for objects in a bucket, but it can just list objects. You could pipe that to a program like sed to replace those listings with object names. For example:

gsutil ls gs://pub/** | sed 's|gs://|https://storage.googleapis.com/|'

The downside here is that this would produce links to all resources, not just those that are publicly visible. So you'd need to either know which resources are publicly visible, or you'd need to write a more elaborate filter based on gsutil ls -L.
