Requests are the guaranteed resources a pod gets. The
scheduler uses this for placement. Limits are the maximum resources a pod can use. If
exceeded, the pod may be throttled (CPU) or OOMKilled (memory).
ResourceQuota sets limits on the total resources (CPU,
memory, pods, etc.) that can be consumed in a namespace. It prevents
resource hoarding.
Cost estimates are based on standard on-demand pricing for
general-purpose instances. Actual costs vary based on region, instance
type, reserved capacity, and spot instances.
Kubernetes Resources FAQs
Requests vs limits?
Requests guarantee scheduling; limits cap maximum usage. Start with requests≈typical load and add modest headroom.
Language presets guidance
Use presets per runtime, then profile under realistic load. Tune CPU for latency and memory for GC or heap growth.
Avoiding OOMKilled
Set memory limits above peak, monitor RSS, and avoid extreme overcommit for critical workloads.
