Worked example

Inputs

Allocatable CPU
8 cores
Allocatable RAM
32 GiB
Pod CPU request
1.5 cores
Pod memory request
5 GiB
Required pods
27 pods

Expected results

Pods per node
5 pods
Required nodes
6 nodes

How to use this tool

  1. Enter allocatable cpu, allocatable ram, pod cpu request, pod memory request, required pods in the displayed units.
  2. Calculate the scenario, then compare it with measurements before changing a system.

Try this example

{
  "cpu": 8,
  "mem": 32,
  "pc": 1.5,
  "pm": 5,
  "n": 27
}

Accuracy and scope

Identical nodes and pods; ignores affinity, system reserves beyond allocatable values, storage and scheduling constraints.
