Google GKE Guide — KubeBolt Docs

Authentication

Workload Identity — recommended for in-cluster deployments
GKE comes with Metrics Server pre-installed

Helm with GCE Ingress

helm install kubebolt \
  oci://ghcr.io/clm-cloud-solutions/kubebolt/helm/kubebolt \
  --set ingress.enabled=true \
  --set ingress.className=gce

GKE Autopilot clusters are compatible — no privileged containers needed.

Google Managed Prometheus (GMP)

If your metrics already live in GMP, deploy the optional agent in promread mode and it reads the metric families straight from your project, authenticating with GCP IAM (Workload Identity supported) — no second scrape pipeline. Configure it from the Add Cluster wizard — see Connecting clusters and Metrics.
