Summary
Documents new validation rules for GKE cluster names that reject reserved Google Cloud Storage substrings (
google,g00gle,goog,g00g) at cluster creation time.Why
A recent platform change adds up-front validation for GKE cluster names. Because Porter derives GCS bucket names (for example, for Loki object storage) from the cluster name, and GCS hard-rejects bucket names containing these substrings, a cluster using a name like
rajeev-googlewould silently fail to fully provision and the only recovery path was recreating the cluster. The platform now rejects these names at contract validation time so users fail fast on cluster create.Changes
