gke/BP/2023_004
GKE clusters are VPC-native.
Product: Google Kubernetes Engine
Rule class: BP - Best practice, opinionated recommendation
Description
It’s recommended to use VPC-native clusters. VPC-native clusters use alias IP address ranges on GKE nodes and are required for private GKE clusters and for creating clusters on Shared VPCs, as well as many other features.
VPC-native clusters scale more easily than routes-based clusters without consuming Google Cloud routes and so are less susceptible to hitting routing limits.
Remediation
Migrate to VPC-Native cluster by recreating the cluster.
