How to get project name/id from Google Cloud Storage bucket?

Question

I'm given a Google Cloud Storage bucket address (gs://some_bucket_name) to which I've already been granted read access. The bucket belongs to another project. Is there any way for me to find out what the project name or id that the bucket belongs to?

Answer 1

A good question.

Buckets don't have obvious scoping to projects and their globally unique names aren't presented as part of hierarchy that includes project identifiers.

However... acls may be a good bet... I'm not certain that this definitive, please check:

gsutil acl get gs://[[BUCKET-NAME]]

Which yields the projectNumber:

[
  {
    "entity": "project-owners-123456789012",
    "projectTeam": {
      "projectNumber": "123456789012",
      "team": "owners"
    },
    "role": "OWNER"
  },
  {
    "entity": "project-editors-123456789012",
    "projectTeam": {
      "projectNumber": "123456789012",
      "team": "editors"
    },
    "role": "OWNER"
  },
  {
    "entity": "project-viewers-123456789012",
    "projectTeam": {
      "projectNumber": "123456789012",
      "team": "viewers"
    },
    "role": "READER"
  }
