Tried to create GKE cls, got error message: Service account "firstname.lastname@example.org" does not exist. Does this have something to do with billing?
Hello! I’d like to start by pointing out something related to your comment that might seem a bit pedantic but is actually important: You don’t actually do things in your trial account, because that’s a billing account. Rather, you do something in a project which might happen to be linked to your trial billing account. So that leads me to my question that I hope will help you get unblocked…
Are you doing this–creating the GKE cluster–inside your networking project or in another one? I would recommend that you use a new project for this GKE stuff–or at least your "Services Exploration Labs" one–because we messed around with the service accounts in the networking project and that could cause this error.
