# 11-billing-iam-hardening.sh — GCP Billing Account Health fixes
|

# Løser to offisielle GCP-advarsler:
|
|
# 1. "0 billing account viewers" — gir billing.viewer til spesifiserte brukere
|
|
# 2. "Billing Account Creator rolle på for domenet" — fjerner domain-wide Creator
|
|
#
|
|
# Agent-identitet: jason.vauger@vauco.no får billing.viewer
|
|
# slik at agenten kan hente og rapportere kostnadsdata autonomt.
|
|
#
|
|
# Krav: du må være Billing Account Administrator for å kjøre dette.
|
|
# Source .env før kjøring: source .env
