How to determine GCP project of a GCS bucket

How to determine GCP project of a GCS bucket

The Problem Statement

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.

Done

The problem of “shifting all items” in a Terraform array

In Terraform, it’s very easy to use count & count.index to create a series of similar resources from a single array. locals { roles = [ "roles/viewer", "roles/storage.admin", "roles/compute.admin", "roles/cloudsql.admin" ] } resource "google_project_iam_member" "group_access" { count = length(local.roles) role = local.roles[count.index] member = "group:devs@example.com" }
