When there are any issues with a GCS (google cloud storage) bucket in GCP (google cloud platform), our teams / SREs / executives would almost always know (either or all of) the following info about the bucket:
bucket name
public URL
authenticated URL
gsutil URL
etc etc
However, from these info, it’s not clear which GCP project (out of the gazillion GCP projects in an organization account) owns the specific bucket.
The Solution
Step 1: Determine projectNumber using the bucket API explorer > Just add the bucket name into the bucket field of the form and leave everything else default as it is.
Step 2: Determine PROJECT_ID using the ‘gcloud projects list’ command
gcloud projects list --filter="projectNumber:<PROJECT_NUMBER>"
Thus, you can find out the PROJECT_ID / PROJECT_NAME of the GCS bucket.
