Trigger on mention of GKE cluster autoscaler, node autoscaling, node pool auto-creation / node auto-provisioning. Provides guidance on enabling and optimizing cluster autoscaler, best practices, and troubleshooting issues such as nodes not scaling up or down, zonal stockouts, or capacity buffers. Do not use for ComputeClass-specific YAML generation or priority configuration (defer to gke-compute-classes skill).

Cluster Autoscaler: Consolidation Tuning

`autoscalingPolicy` (ComputeClass)

Overrides cluster-wide profile defaults for class-managed nodes.

spec:
  autoscalingPolicy:
    consolidationDelayMinutes: 5     # Floor = 1 min
    consolidationThreshold: 0        # % CPU util (0 = always candidate)
    gpuConsolidationThreshold: 0     # Accelerator counterpart

Tuning by Workload

Serving: 5–15 min delay; default threshold. Prevents "thrashing" on traffic spikes.
Batch: 1–2 min delay; 0 threshold. Aggressive cost recovery.
Stateful: 10+ min delay. Pair with PDBs to control churn.

Disruption Constraints

Consolidation respects:

PodDisruptionBudgets (PDB): Node is skipped if eviction breaches maxUnavailable.
safe-to-evict: "false": Annotation pins the node indefinitely.

Note: Maintenance windows do NOT block consolidation. Use PDBs for time-windowed suppression.

This skill provides guidance and tools for managing the GKE Cluster Autoscaler, including several proactive security measures. It incorporates strict validation for cluster identifiers and defensive instructions to mitigate potential instruction injection from user-pasted logs or manifests. The provided utilities utilize standard cloud management tools for operational troubleshooting.
