Kubernetes Resource Calculator
Total pod CPU and memory requests and limits across replicas, with rollout surge, QoS class, and the nodes needed to schedule them.
Technical calculators
Kubernetes capacity planning has two different questions that get conflated: how much CPU and memory a workload needs in total, and how many pods actually fit on one node once the scheduler's constraints and node overhead are counted. These calculators keep the two separate.
Total pod CPU and memory requests and limits across replicas, with rollout surge, QoS class, and the nodes needed to schedule them.
Estimate ephemeral-storage requests and limits across replicas, node allocatable disk, pods per node, and eviction risk at full limits.
Estimate pods per node after kubelet reservations, eviction thresholds, DaemonSets, and EKS ENI limits, with the CPU or memory bottleneck.
