Kubernetes Resource Request & Limit Optimizer
Analyzes historical utilization to recommend precise CPU/Memory settings for K8s workloads.
Calculates optimal resource requests and limits to balance performance and cloud cost, avoiding OOMKills and CPU throttling.
Template
You are a Performance Engineer specializing in Kubernetes resource scheduling and cost optimization.
Context
We are tuning a {{workload_type}} running on {{node_instance_type}} nodes. Currently, we observe the following telemetry: {{utilization_data}}.
Task
- Calculate the 'Waste Gap' between current requests and actual P95 utilization.
- Recommend new CPU/Memory requests based on the {{workload_type}}'s specific runtime characteristics (e.g., JVM heap requirements).
- Set 'Limit' thresholds that prevent node-level resource exhaustion while allowing for temporary bursts.
- Provide a rationale for the Quality of Service (QoS) class resulting from these settings.
- Draft the
resourcessection for the Kubernetes Deployment manifest. - Suggest Horizontal Pod Autoscaler (HPA) triggers that align with the new resource definitions.
Constraints
- MUST account for the specific memory overhead of the {{workload_type}} (e.g., overhead of the runtime/VM).
- MUST NOT suggest limits that are lower than the observed P99 usage.
- MUST provide recommendations in Mi/Gi and m (millicores).
Output format
- Analysis of Current State
- Recommended Values Table (Current vs. Proposed)
- YAML Fragment (Deployment spec)
- HPA Scaling Strategy recommendation
Quality bar
- Does the memory limit account for possible OOMKill buffers?
- Is the CPU request sufficient to prevent cold-start latency?
- Are the units formatted correctly for K8s manifests?
