Manages core GKE cluster provisioning, credentials, Autopilot vs Standard selection, and workload deployment. Use when creating GKE clusters, fetching kubectl credentials, configuring Workload Identity, or deciding between Autopilot and Standard modes. Don't use for specialized GKE networking (use gke-networking), advanced security hardening (use gke-platform-security or gke-workload-security), or cluster upgrades (use gke-upgrades).

Routing Note: For Workload Identity KSA/GSA setup, open
gke-workload-identity/SKILL.md. For cluster security flags (--database-encryption-key,--security-posture, RBAC, Shielded Nodes, Binary Authorization), opengke-platform-security/SKILL.md. For cluster upgrades or maintenance windows, opengke-upgrades/SKILL.md. For generating Kubernetes YAML manifests (Deployment,StatefulSet,Service,HTTPRoute,PodDisruptionBudget), opengke-manifest-generation/SKILL.md.
Managed Kubernetes platform on Google Cloud. Defaults to Autopilot mode unless Standard is explicitly required.
Key Selection Rules: Autopilot vs. Standard
- Default to Autopilot for almost all workloads.
- Use Standard ONLY if:
- Custom node OS kernel parameters (
sysctl) are required. - Custom node taints or specific hardware node pools are required.
- DaemonSets require raw
hostPathmounts to the host OS filesystem.
- Custom node OS kernel parameters (
- When explaining why Standard is required over Autopilot, explicitly cite all matching restrictions (e.g., custom sysctls and custom node taints).
- For advanced cluster architecture or complex node pool creation planning, refer to
gke-cluster-creation.
Critical Gotchas & Best Practices
Private Autopilot Clusters:
- Use
--enable-private-nodesfor private node IP addresses. - Use
--enable-private-endpointto disable public IP access to the control plane. - Restrict control plane access with
--enable-master-authorized-networksand--master-authorized-networks=CIDR_BLOCK:gcloud container clusters create-auto CLUSTER_NAME --region=REGION \ --enable-private-nodes \ --enable-private-endpoint \ --enable-master-authorized-networks \ --master-authorized-networks=CIDR_BLOCK
- Use
Workload Identity (IAM Binding):
- Never mount raw GCP Service Account JSON keys in Pods; open
gke-workload-identity/SKILL.mdfor KSA/GSA setup.
- Never mount raw GCP Service Account JSON keys in Pods; open
Autopilot Resource Requests:
- In Autopilot, CPU requests must be specified in increments of 250m (0.25 vCPU). If an unaligned CPU request (e.g., 300m) is requested, round up to the nearest 250m increment (500m / 0.5 vCPU).
- Resource requests equal limits automatically. Omit
limitsto allow Autopilot to set defaults matchingrequests.
Cluster Credentials:
- Always explicitly specify
--region(for regional clusters) or--zone(for zonal clusters) when fetching credentials:gcloud container clusters get-credentials CLUSTER_NAME --region=REGION --quiet
- Always explicitly specify
