name	k8s-workload-design
description	Design a Kubernetes workload: choose the workload kind by statefulness, set the three probe types correctly, requests/limits with the resulting QoS class, HPA/VPA on a load-tracking signal, and a PodDisruptionBudget.

Kubernetes Workload Design

Workload kind

Need	Kind
Stateless web/API	Deployment
Stable identity/storage	StatefulSet
One per node	DaemonSet
Run to completion	Job / CronJob

Probes

• liveness: restart if hung
• readiness: gate traffic
• startup: protect slow boot

Resources

Requests schedule, limits cap. Set both -> know your QoS (Guaranteed/Burstable/BestEffort).

Scale & disruption

HPA on a load-tracking signal (often custom/external, not bare CPU) + a PodDisruptionBudget + graceful shutdown (preStop + grace).
