Explanation

A GKE cluster with a private endpoint is only reachable from networks that have private connectivity to the control plane (same VPC or peered). By default, Cloud Deploy uses a public Cloud Build pool, which cannot reach the private endpoint. Creating a Cloud Build private pool that is peered with the same VPC as the GKE cluster, and configuring Cloud Deploy to use this pool as its execution environment, gives the deploy job private network access to the cluster and resolves the deployment failures.
