What this tool does not do / Limits

This is simple multiplication of the numbers you enter. It does not read a live cluster, account for node overhead, or guarantee that a workload will schedule.

Frequently asked questions

Are limits required?

No. If you leave limits blank, the request values are used for the limit totals too.

Does this check my cluster capacity?

No. It only calculates from the numbers you enter; compare the totals with your own node capacity.
