Accurately calculate CPU and memory resources for your Kubernetes deployments. This calculator helps you determine appropriate request and limit values for containers, pods, and entire deployments while ensuring optimal Quality of Service (QoS) class assignment.
Set appropriate requests to ensure your pods get scheduled and receive guaranteed resources.
Configure proper limits to prevent runaway containers from impacting other workloads.
Right-size resources to maximize cluster efficiency without over-provisioning.
Understand how your resource configuration affects pod priority during node pressure.
Requests are guaranteed resources used for scheduling decisions. Limits are the maximum resources a container can use. A container can exceed its request (if available) but never its limit.
Guaranteed: requests equal limits for all resources. Burstable: at least one request or limit set, but not equal. BestEffort: no requests or limits set. During node pressure, BestEffort pods are evicted first.
Not necessarily. CPU is compressible, so setting higher limits allows bursting. However, for predictable performance, some prefer matching request and limit for Guaranteed QoS.
Unlike CPU which gets throttled, exceeding memory limit triggers OOMKill (Out of Memory Kill). The container is terminated and potentially restarted based on restart policy.
Start by profiling your application under load. Set requests to the typical usage and limits to handle peak load. Use tools like kubectl top or Prometheus to monitor actual consumption.
